AMD Phenom II X6 1090T 6-Core Processor Review
Date: Apr 27, 2010
Author: Marco Chiappetta
Introduction and Related Information

Way back in November of 2007, AMD unveiled all of the components of the "Spider" platform, which consisted of a Phenom processor, 700-series chipset-based motherboard, and Radeon HD 3800 series graphics. A little over a year later, in January of 2009, AMD completed a refresh of their total platform and dubbed it "Dragon". Similarly, the Dragon platform consisted of an all-AMD processor, chipset, and GPU combo, but this time the Phenom II, a revamped 700-series chipset with a new southbridge, and Radeon HD 4800 series graphics were at the heart of the platform. Do you see a pattern forming, here?

If you recalled AMD's platform roll-out plans for the last few years, the new "Leo" platform we'll be showing you in this article may not come as a total surprise. After all, we have already shown you the 890GX chipset, the first in the 800-series. And we've almost lost count of how many Radeon HD 5000-series graphics cards we've featured on these pages. Today, AMD completes the platform picture with the release of a new series of six-core processors, aptly named the Phenom II X6. We should also point out a new enthusiast-class chipset is arriving alongside the Phenom II X6, the 890FX.

We hinted at the Phenom II X6's arrival in our coverage of the
AMD 890GX chipset a few weeks back. And if you're familiar with AMD's chipset naming convention, figuring out what makes the 890FX tick shouldn't be too difficult--whereas the 890GX features integrated graphics, the 890FX does not. But there are a few more wrinkles to the story we'll explain on the pages ahead. For now, check out the features and specifications of the new 3.2GHz Phenom II X6 1090T and 2.8GHz 1055T processors arriving today, and then move on for the rest of the scoop...

AMD Phenom II X6 1090T Processor

AMD Phenom II X6 Processors
Specifications & Features

The new Phenom II X6 is the final piece of the Leo platform. As we've already mentioned, however, some of the components of the Leo platform are not new. In fact, most of its core components have already been available for quite some time now. As such, we have already covered them in-depth here on HotHardware in previous articles, so we won't do the same again here. We will, however, recommend that you take a look at a few recent articles to get familiar with the underlying technology and components that comprise AMD's Leo platform.

All of the various Radeon HD 5000 series, 890-series chipset, Phenom, Phenom II, and Athlon related articles listed above cover the gamut of features that are avaialble with the AMD Leo platform--with the exception of the new Phenom II X6 1090T featured here, of course.

New Feature: Turbo CORE

Although the new Phenom II X6 1090T has two more cores than previous Phenom II X4 processors, the executions cores themselves are largely unchanged; there are just more of them in the X6. However, with this new generation of processors, AMD is introducing a new feature dubbed Turbo CORE.

Since the introduction of their Nehalem microarchitecture, Intel's processors have been outfitted with a feature called Turbo Boost that in essence overclocked one or more of the processor's cores under certain workload conditions, power and thermals permitting. Turbo Boost afforded the processors the ability to enhance the performance of lightly-threaded workloads by increasing the performance of active cores, while inactive cores remained idle. AMD's new Turbo CORE technology functions in a similar way.

AMD's Turbo CORE technology automatically increases the frequency of three active CPU cores by up to 500MHz, without the need for any special software or drivers. The technology will be enabled on Phenom II X6 processors and will work with all AM3-based motherboards after a BIOS update. The Phenom II X6 1090T we tested has a peak Turbo CORE frequency of 3.6GHz, while the 1055T which is arriving today maxes out at 3.3GHz.

AMD Turbo CORE Technology Explained; Click For Larger View

Turbo CORE technology works by putting three cores into a boost-enabled P-state when power consumption is below the processor's rated TDP. Being in the boost-enabled P-state doesn't necessarily mean the three cores are overclocked by 500MHz immediately, but rather that they are ready to have their frequencies increased based on the processing workload. When Turbo CORE is active, Cool 'n' Quiet still functions, so each core could be operating at anywhere up to that maximum clock, but is not necessarily at the absolute maximum. And the individual cores don't necessarily have to be operating at the same frequency either. Essentially, when three or more of a Phenom II X6's six cores are at low or no utilization, the processor determines that it is in a boost-eligible state, and the active cores are put into a Turbo-enabled state to increase performance. According to AMD, the active cores must be in a software P0 state for transition to boost and the processors will fully utilize available TDP budget to maximize performance, while remaining within electrical limits.

Vital Signs and Overclocking

Below are a couple of pictures of the AMD Phenom II X6 1090T processors.  As you can see, from the outside, there is little to differentiate it from its socket-AM3 based counterparts.

AMD Phenom II X6 1090T

The AMD Phenom II X6 1090T is based on the processor core codenamed Thuban. It, and other Phenom II X6 processors, feature 768K of total L1 cache (64K instruction and 64K data cache, per core), 3MB of L2 cache (512KB per core), and 6MB of shared L3 cache. The processors are manufactured using Global Foundries' 45nm SOI process technology and have a die size of 346mm2. Like other socket-AM3 based processors, the Phenom II X6 supports both DDR2 and DDR3 memory types and they feature one 4GT/s HyperTransport link.

CPU-Z Phenom II X6 Processor Details

If we use CPU-Z to verify, the information outlined above is confirmed. According to CPU-Z, the Phenom II X6 1090T we tested is based on stepping 0 of the Thuban core. And as you can see, its default clock speed is 3.2GHz, which is derived my multiplying 16--the processor's stock multiplier--with the standard 200MHz HT base clock. Please note, however, with Turbo CORE enabled, the 1090T's frequency will peak at 3.6GHz.

Overclocking The Phenom II X6 1090T

AMD Phenom II X6 1090T Overclocked to 4.01GHz

We also spent some time overclocking the new AMD Phenom II X6 1090T processor, using a stock AMD PIB cooler. For our overclocking tests, we bumped the CPU voltage up to 1.5v in the system BIOS of the MSI 890FXA-G70 motherboard, increased the Turbo CORE multiplier to 19.5x, and then from within Windows we used the AMD Overdrive to slowly increase the base HT frequency until our test system was no longer stable. In the end, we were able to take the Phenom II X6 1090T up to a completely stable 4.01GHz. At those speeds, even with a stock air-cooler, core temps hovered around the 68'C mark, which is lower than we expected. Considering how easy it was to take our CPU over the 4GHz mark, we suspect that somewhat higher clock speeds will be possible with exotic cooler and more aggressive voltage tweaking.

Enter The 890FX Chipset

To coincide with the launch of the Phenom II X6 processor family, AMD is also launching the enthusiast class 890FX chipset. As its name suggests, the 890FX is very similar to the 890GX, minus the integrated graphics core. The 890FX, however, also sports some additional PCI Express lanes for true x16 / x16 CrossFire support...

AMD 890FX Chipset Block Diagram

Above is a high-level block diagram of the new AMD 890FX / SB850 chipset. As you can see, the chipset supports AMD socket AM3 processors with DDR3 memory, and features a total of 42 PCI Express lanes, with flexible configuration options.

Other features of the 890FX chipset a full HT 3.0, 5.2GT/s link between the CPU and NB. A an Alink Express III interface with 4GB/s of bandwidth between the 8F0GX and SB850. The SB850 features all of the typical amenities of a modern chipset; USB 2.0, HD Audio, Gigabit Ethernet, PATA, and PCI are present. In addition, the SB850 also features an additional pair of PCI Express Gen 2 x1 lanes, along with native support of SATA 6G.

AMD 800-Series Chipset Feature Comparison Chart

The 890GX and 890FX aren't the only members of the 800-series chipset family, however. The chart above breaks down the features of the 890FX, 890GX, 870, and 880G chipsets, along with their companion southbridge chips. Like the previous generation 770, the 870 is a pared down version of the 890GX without a graphics core. The 880G, however, does feature a DirectX 10.1 IGP, albeit a less powerful one than what's incorporated into the 890GX.

AMD 890FX Motherboards: Asus, MSI

To test out the AMD Phenom II X6 1090T processor, we procured a couple of 890FX-chipset based motherboards from Asus and MSI, the CrossHair IV Formula and the 890FXA-GD70, respectively...


Asus CrossHair IV Formula

Asus' CrossHair motherboards for the AMD platform have been some of our favorites. Previous iterations of the CrossHair have all been outfitted with some unquie features to help differntiate them from the crowd, and the CrossHair IV Formula is no different.  The CrossHair IV Formula features support for USB 3.0 and SATA 6G, and the board's chipset and VRM are cooled by large angular-shaped heatsinks, linked together via heat-pipes. But the board also supports a number of Asus proprietary technologies like ExpressGate, MemOK, and TurboV, among others.

The CrossHair IV Formula is outfitted with four PCIe x16 slots and a pair of legacy PCI slots. It sports a dark colored PCB with distinctive red, black and white accents, and as is typical of high-end offerings from Asus, the board is loaded with features. The CrossHair IV Formula supports Asus' TurboV real-time overclocking, Core Unlocker, MemOK, and features integrated SupremeFX X-Fi audio. It also supports Asus' GameFirst technology, which prioritizes game packets through the integrated gigabit NIC, and RoG connect. The RoG Connect port in the CrossHair IV Formula's backplane will allow users to connect the board to a second system (like a notebook or netbook) for real-time hardware monitoring and tweaking. Very cool.

Overall, the layout of the CrossHair IV Formula is excellent, as was the layout of its feature-laden BIOS, and working with the board proved to be a pleasure, at least in the short time we've had with it.



Like Asus' offering, the MSI 890FXA-GD70 is a feature-rich motherboard that exploits all of the inherent capabilities of the 890FX-chipset, in addition to a few added features courtesy of MSI. The 890FXA-GD70 is built upon a dark colored PCB with blue and black accents. The 890FX and VRM are situated under a relatively large heatsink that rests between the CPU socket and backplane and the SB850 southbridge is under its own heatsink, situated in the traditional southbridge location. Both heatsinks are linked via heat-pipe. Along with SATA6G support (which comes by way of the SB850), the MSI 890FXA-GD70 also supports USB 3.0 a few other MSI-proprietary features. MSI claims the board uses "Military Class Components" to ensure longevity and stability, and the 890FXA-GD70 it is outfitted with an OC Dial that gives users the ability to overclock by simply turning a knob on the board (it is visible in the corner by the power and reset switches).

The MSI 890FXA-GD70 has five PCI Express x16 slots, a single x1 slot, and a single PCI slot, and its I/O backplane is loaded with other connectivity options, including eSATA, USB 3.0, audio, etc. Overall, the layout of the board is very good and we had no issues with its installation into a generic mid-tower case. The layout of its BIOS is also very good and should please even the most ardent overclockers.

Test Systems and SiSoft SANDRA

Test System Configuration Notes: When configuring our test systems for this article, we first entered their respective system BIOSes and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set memory timings for either DDR3-1333 with 8,8,8,24 timings. The hard drives were then formatted, and Windows 7 Ultimate x64 was installed. When the Windows installation was complete, we updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled, finally, we installed all of our benchmarking software, performed a disk clean-up, defragged the hard drives, and ran all of the tests.

 Preliminary Testing with SiSoft SANDRA 2010 SP1
 Synthetic Benchmarks

We began our testing with SiSoftware's SANDRA 2009 SP4, the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2009 SP4 suite with Intel's new Core i7-980X Extreme (CPU Arithmetic, Multimedia, Memory Bandwidth, and Cache and Memory).  All of the scores reported below were taken with the processor running at its default clock speeds of 3.2GHz with 4GB of DDR3-1333 RAM running in dual-channel mode on the MSI 890FX-GD70 motherboard.

Processor Arithmetic
Phenom II X6 1090T

Phenom II X6 1090T

Memory Bandwidth
Phenom II X6 1090T

Cache and Memory
Phenom II X6 1090T

The AMD Phenom II X6 1090T performed well in the various SiSoft SANDRA tests that we ran. In the processor arithmetic and multimedia benchmark, the CPU finished about in the middle of the pack, unable to overcome the higher-end Intel processors. In the memory bandwidth test, the AMD platform offered up over 12GB/s of peak bandwidth, and in the combined cache and memory test, the Phenom II X6 finished at the top of the charts.

Futuremark PCMark Vantage

Next up, we ran a number of different test systems through Futuremark‚Äôs latest system performance metric, PCMark Vantage. PCMark Vantage runs through a host of different usage scenarios to simulate different types of workloads including High Definition TV and movie playback and manipulation, gaming, image editing and manipulation, music compression, communications, and productivity.  Most of the tests are multi-threaded as well, so the tests can exploit the additional resources offered by a multi-core CPU.

Futuremark PCMark Vantage
Simulated Application Performance

According to PCMark Vantage, the new AMD Phenom II X6 1090T performed somewhere in between the Core i7 975 (Bloomfield) and the Core i7 870 (Lynnfield), and it was clearly the fasted AMD-built processor yet. Of course, considering Intel's high-end quad-core was able to outpace the Phenom II X6 1090T here, the Core i7 980X six-core was fastest overall.

LAME MT and x264 Encoding

In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content.  LAME is an open-source mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications.

Audio Encoding

In this test, we created our own 223MB WAV file (a hallucinogenically-induced Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.


The LAME MT benchmark showcases the effectiveness of AMD's Turbo CORE technology. In this test, despite the 1090T's 200MHz default clock speed disadvantage versus the Phenom II X4 965, the 1090T is able to pull ahead of the X4. When Turbo CORE is enabled, the 1090T peaks at 3.6GHz and is able to outpace the X4. Intel's processors have an obvious advantage here, however.

x264 Video Encoding Benchmark
H.264 HD Video Encoding

The x264 benchmark measures how fast a system can encode a short, DVD quality MPEG-2 video clip into a high-quality H.264 HD video clip. The application reports the compression results in frames per second for each pass of the video encoding process, and it is threaded so it can take advantage of the additional resources afforded by multi-core processors.

Surprisingly, in the first pass of the x264 benchmark, the Phenom II X6 1090T trailed the X4 965. In the second pass of the test, however, the additional cores of the X6 allowed it to significantly outperform the Phenom II X4, although it just missed the mark set by the Core i7 870.

Cinebench R11.5 and POV-Ray

Cinebench R11.5 is an OpenGL 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by 3D animation houses and producers like Sony Animation and many others. It's very demanding of system processor resources and is an excellent gauge of pure computational throughput.

Cinebench R11.5
3D Rendering

This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The rate at which each test system was able to render the entire scene is represented by the Cinebench scores in the graph below.

The Phenom II X6 1090T performed very well in the CInebecnh R11 benchmark. Here, AMD's new 6-core chip performed right in between the Core i7 975 and Core i7 870, but well ahead of the Phenom II X4 965.

POV-Ray Performance
Ray Tracing

POV-Ray , or the Persistence of Vision Ray-Tracer, is a top-notch open source tool for creating realistically lit 3D graphics artwork. We tested with POV-Ray's standard 'all-CPU' benchmarking tool on all of our test machines, and recorded the scores reported for each. Results are measured in pixels-per-second throughput; higher scores equate to better performance.

Our POV-Ray benchmark results mirror those of Cinebench above. The Phenom II X6 1090T almost catches the Core i7 975, and puts a beating on the Phenom II X4 965. Nothing can catch the Core i7 980X, though.

WinRAR Compression and Image Processing

In our custom WinRAR x64 benchmark, we take a directory loaded with two hundred, 12.1 megapixel image files and compress them into a single archive using the default WinRAR compression scheme. The length of time it took each system to save the completed archive is represented in the graph below.

WinRAR x64 v3.9 Benchmark
Multi-Threaded File Compression Performance


WinRAR didn't fully utilize the processor resources offered by the Phenom II X6 1090T, but it was still able to outpace the Phenom II X4 965 due to the effectiveness of AMD's Turbo CORE technology.

VSO Image Resizer
Batch Image Processing

For this next test, we use the VSO Image Resizer utility to convert two hundred, 12.1 megapixel image files copied directly from a digital SLR camera to compressed, 640x480 JPGs, suitable for the web. We used the Lanczos filtering method available within the application, which is slower, but offers higher quality compression than most other methods.

Our custom VSO Image Resizer test showed a performance trend that was very similar to WinRAR. In this test, again, the additional resources offered by the 6-core 1090T weren't fully exploited, but the processor's higher-clock when Turbo CORE is engaged gives it the ability to outrun the Phenom II X4 965.

3DMark06 and Vantage CPU Tests

3DMark06's built-in CPU test is a multi-threaded DirectX gaming metric that's useful for comparing relative performance between similarly equipped systems.  This test consists of two different 3D scenes that are processed with a software renderer that is dependent on the host CPU's performance.  Calculations that are normally reserved for your 3D accelerator are instead sent to the CPU for processing and rendering.  The frame-rate generated in each test is used to determine the final score.

Futuremark 3DMark06
Synthetic DirectX Gaming

The trend we've seen up to this point continued in the 3DMark06 CPU benchmark, where the new Phenom II X6 1090T finished in between the Core i7 870 and i7 975, but well ahead of the Phenom II X4 965.

Futuremark 3DMark Vantage
Synthetic DirectX Gaming

3DMark Vantage's CPU Test 2 is a multi-threaded test designed for comparing relative game physics processing performance between systems.  This test consists of a single scene that features an air race of sorts, with a complex configuration of gates. There are aircraft in the test that trail smoke and collide with various cloth and soft-body obstacles, each other, and the ground. The smoke spreads, and reacts to the planes as they pass through it as well and all of this is calculated on the host CPU.

The new Phenom II X6 1090T fared somewhat worse in the 3DMark Vantage CPU Test 2. Here, AMD's new 6-core just missed the mark set but the Core i7 870, but it was much faster than the Phenom II X4 965.

Low-Res Gaming: Crysis and ETQW

For our next set of tests, we moved on to some in-game benchmarking with Crysis and Enemy Territory: Quake Wars. When testing processors with Crysis or ET:QW, we drop the resolution to 800x600, and reduce all of the in-game graphical options to their minimum values to isolate CPU and memory performance as much as possible.  However, the in-game effects, which control the level of detail for the games' physics engines and particle systems, are left at their maximum values, since these actually do place some load on the CPU rather than GPU.

Low-Resolution Gaming: Crysis and ET: Quake Wars
Taking the GPU out of the Equation

The new 6-Core Phenom II X6 1090T performed right on-par with the Phenom II X4 965 in our low-res gaming tests, which is to say it performed well, but not quite as well as Intel's offerings.

Total System Power Consumption

We'd like to cover a few final data points before bringing this article to a close. Throughout all of our benchmarking and testing, we monitored how much power our test systems consumed using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the processors alone.

Total System Power Consumption
Tested at the Outlet

AMD claimed the six-core Phenom II X6 would fall within the same 125W TDP as the previous generation quad-core Phenom II, and they wern't kidding. In our total system power consumption tests, the new Phenom II X6 1090T consumed less power than the Phenom II X4 965 while idling, and only about 12 - 18 more watts under load, despite offering much better overall performance. Intel's Bloomfield-based Core i7 processors / platforms consumed more power than the Phenom II X6 under both idle and load conditions, but the Lynnfield-based Core i5 and i7 processors / platform was the most power friendly overall.

Performance Summary and Conclusion

Performance Summary: The new AMD Phenom II X6 1090T six-core processor performed very well throughout our entire battery of benchmarks. In the more heavily multi-threaded tests, the additional processor resources of the Phenom II X6 1090T allowed it to pull well ahead of AMD's previous flagship quad-core CPU, the Phenom II X4 965. And in all but a couple of tests, performance of the AMD Phenom II X6 1090T fell somewhere in between the Intel Core i7 870 (Lynnfield) and i7 975 (Bloomfield), although it was much closer to the 975 more often than not. With single or lightly-threaded workloads the AMD Phenom II X6 1090T also performed well, and thanks to its support for Turbo CORE technology, it was able to surpass the Phenom II X4 965 in these tests as well, despite the latter's higher default clock speed (3.2GHz vs. 3.4GHz). With that said, the 6-core Intel Core i7 980X was significantly faster overall, but it is also 3x the price of the AMD Phenom II X6 1090T.

First things first. We really like the new AMD Phenom II X6 1090T processor. It may not be the undisputed performance champion in light of Intel's excellent offerings, but all things considered, the Phenom II X6 1090T is a heck of processor for under $300 and it's undeniably the fastest to ever come out of AMD. Our tests showed the 1090T performing in roughly the same neighborhood as the Core i7 870 and Core i7 975 depending on the application, but the Phenom II X6 1090T costs hundreds of dollars less than both. Turbo CORE worked as advertised and helped push the 1090T's performance ahead of AMD's previous flagship Phenom II X4 965 in some lightly-threaded workloads.  The Phenom II X6 1090T also overclocked well, and its power consumption is right in line with previous-gen quad-cores. Factor in the AMD Phenom II X6 1090T processor's compatibility with existing socket AM2+ and AM3 motherboards and it's a compelling option to be sure, other than the fact that Intel still has a performance advantage at the ultra high end.

AMD Phenom II X6 1090T In The MSI 890FXA-GD70 Motherboard

AMD is officially launching two six-core processors today, the $285 AMD Phenom II X6 1090T we looked at here and the lower-clocked $199 Phenom II X6 1055T. An X6 1035T and a Phenom II X4 960T quad-core based on Thuban should be arriving soon as well. A handful of 890FX-based motherboards should be hitting the scene too. All things considered, there is a lot to like with regard to AMD's Leo platform. No, it's not the fastest platform out there; that distinction still belongs to Intel's Core i7 / X58 combo, but at its price point the AMD Phenom II X6 1090T is a very compelling option. Mate a Phenom II X6 1090T to a decent 890FX-based motherboard, a few gigabytes of RAM, and a Radeon HD 5800 series card, and you'll have the foundation of one heck of a powerful rig without breaking the bank. It may not be the "Intel killer" AMD fans may have been hoping for, but that doesn't matter. The Phenom II X6 is a strong product at a very competitive price, and that's good enough to earn it a Recommended Award in our book.
