AMD FX-8370 and FX-8370E 8-Core CPU Reviews

Test Setup and PCMark 7 and 8

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 the memory speed to each platform's highest, officially supported frequency--1866MHz in the case of AMD's newest FX series processors.

The solid state drives in the test systems were then formatted, and Windows was installed. When the Windows installation was complete, we fully updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, performed a disk clean-up, cleared any prefetch and temp data, and ran the tests.

Futuremark PCMark 7
General Application and Multimedia Performance

Futuremark's PCMark 7 is a whole-system benchmarking suite. It has updated application performance measurements targeted for a Windows environment and uses newer metrics to gauge relative performance. Below is what Futuremark says is incorporated in the base PCMark suite and the Entertainment, Creativity, and Productivity suites--the four modules we have benchmark scores for you here.

In PCMark 7, the FX-8350 pulls ahead of both the FX-8370E and FX-8370. There's no clear reason why this is the case, though we suspect its because the chip is turboing to higher clocks, for longer stretches. The good news is that the full-powered FX-8350 and the lower power FX-8350E score virtually identically; AMD doesn't appear to be taking a performance hit for hitting that lower TDP target.

PCMark 8 v2
System Level Benchmark

PCMark 8 v2 is the latest version in Futuremark’s series of popular PC benchmarking tools. It is designed to test the performance of all types of systems, from tablets to desktops. PCMark 8 offers five separate benchmark tests--plus battery life testing—to help consumers find the devices that offers the perfect combination of efficiency and performance for their particular use case. This latest version of the suite improves the Home, Creative and Work benchmarks with new tests using popular open source applications for image processing, video editing and spreadsheets. A wide variety of workloads have also been added to the Work benchmark to better reflect the way PCs are used in enterprise environments.

These tests can be run with our without OpenCL acceleration. We chose to run with OpenCL acceleration enabled to leverage all of the platforms’ CPU and GPU compute resources…

In PCMark 7, AMD platforms lag badly compared to the Intel CPUs but in PCMark 8 that trend is reversed. This is thanks to better OpenCL support in AMD's driver stack and possibly better multi-threading performance thanks to the FX-8370's eight real cores, compared to the 4670K's quad core (no Hyper-Threading on this model).
