Intel Core i7-4770K Review: Haswell Has Landed

18 thumbs up
With the release of the Haswell architecture, Intel's new integrated graphics cores will be branded with the “Iris” moniker. Now, we’ll see Intel HD 5000 graphics along with the higher-end Intel Iris Graphics 5100 and Iris Pro Graphics 5200; previously, these were codenamed GT3 (15W), GT3 (28W), and GT3e, respectively. Iris graphics are primarily designed for mobile devices, and we’ll be seeing them in Intel-based ultrabooks, higher-end notebooks, and desktop all-in-one devices. Upcoming Haswell desktops will still be branded as "Intel HD Graphics." High-end desktop parts will carry the "HD 4600" label, with lower-end parts branded as "HD 4400" and "HD 4200."



Iris brings new features including integrated on-package eDRAM memory for the GT3e graphics core, DX11.1, OpenGL 4.0, and OpenCL 1.2 support, double the bandwidth with DisplayPort 1.2, support for a 3-screen collage display, faster Intel Quick Sync Video performance and fast JPEG decode and MPEG encode.  Of note is the GT3e's eDRAM (embedded DRAM) cache complement that dramatically increases bandwidth and lowers latency with much faster access for the graphics and CPU cores.  Again, this is a feature for mobile Iris Graphics variants only, however.



Intel is claiming overall performance improvements of up to 2X for Iris Graphics, over previous 3rd Gen Ivy Bridge integrated graphics. The company also boasts that Iris will bring triple the 3D performance for desktop R-series chips. The R-series chips are the BGA-only (non-socketable) variants -- conventional desktop parts will be confined to GT2-class graphics.

Intel will also offer Iris switchable, hybrid graphics implementations with NVIDIA and AMD GPUs, in systems with a discrete graphics card. Iris will also supports 4k UltraHD display output.

We'll be stepping through benchmark numbers of the desktop Intel HD 4600 series devices in the pages ahead but you'll have to wait for our Haswell mobile coverage to get a glimpse of Iris graphics in action, along with our direct confirmation of Intel's performance claims you see above.  In the meantime, in case you missed it, you can feast your eyes our quick side-by-side demo of Haswell GT3 Iris graphics in action versus NVIDIA discrete graphics, that we shot earlier this year at CES 2013.


Side-by-side Haswell graphics vs. NVIDIA demo

So, as you can see, Haswell definitely has the chops to at least hang with discrete graphics in Dirt 3 but we'll have more detailed numbers for you in the days ahead as we get Iris Graphics-powered machines in house for testing.

Looks like you could use this CPU as a room heater. Yikes!

Lmao XD

just because it runs at a high temperature doesn't mean it heats more than the previous CPUs. in fact, it doesn't. it only runs at a high temp because the heat spreader isn't soldered to the die. there is a bad heat transfer medium betweem them: the thermal paste.

What makes you say that? A full system under load barely pulled over 100w.

Ill stay on budget pc im not really more on heavy work loads :v

This looks like a very worthy successor to Ivy Bridge for sure, however I was expecting (And so was everyone else I can safely say at this point) to get a little more juice out of this TOCK level CPU.

It's still a freaking wonderful thing, but I'm just a little sad we didn't see much more raw performance gains.

Oh well, it's still amazing, and I certainly would not mind getting a rig built with this as its heart, no sign of that happening ever though :P

Intel is mainly pushing Haswell for better mobile solutions and this review is of the desktop chip!

Features like the Iris Pro GMA 5100/5200 will only be available for the mobile versions and support for the full range of S0ix power states will only be supported on the mobile chips for maximum battery life potential.

So expect more bang for your buck with tablets, hybrids, and laptops that use Haswel than the desktop/server versions...

I'm building a Haswell based computer right now! I just got all my parts yesterday!

I'll be replacing the computer in my sig.

Intel Core i7 4770k

2x 120GB Kingston HyperX 3K SSDs in a RAID 0 (Atto bench results show 1.1GB+ read AND write speeds)

2x 4GB G. Skill DDR3 2400Mhz 10-12-12-31 timings

ASRock x87 Extreme6 MB

Corsair TX850M psu

4x 1.5TB HDD in a raid 10

A lite-on Blu-Ray drive

I will be moving my 660 Ti over to do a couple ot benches to see what improvements the new system has over my last one with the same GPU. I want to wait for the 760 Ti to come out to see how it performs, but if I get impatient, I might just buy a 770.

The system is already assembled except for the 4x 1.5TB drives and I haven't moved the 660ti over yet. I'm on igp right now. i also decided to go with Windows 8. I like it so far, but it is taking a little getting used to.

Nice review, Marco and Dave. Very good information. I have to get a new PC for work and school. Plan on building one, and trying to decide the CPU.

I still have my 980x, no reason to change yet.
