AMD FX 8370 & FX 8370E Review


AMD FX 8370 & FX 8370E Testing:

Testing AMD's FX refresh CPUs, the FX 8370 and FX 8370E will involve running it and its comparison products through OCC's test suite of benchmarks, which include both synthetic benchmarks and real-world applications. The gaming tests will also consist of both synthetic benchmarks and actual gameplay, in which we can see if similarly prepared setups offer any performance advantages. The system will receive a fully updated, fresh install of Windows 7 Professional 64-bit edition, in addition to the latest chipset drivers for each board and GeForce drivers for the NVIDIA GTX 770. To ensure as few variables as possible, all hardware will be tested at their stock speeds, timings, voltages, and latencies, unless otherwise stated. Turbo Boost will be disabled on all processors to make a fair comparison without skewing results. After stock speed testing, each processor will then be overclocked as much as possible, while still maintaining full stability.


Testing Setup: AMD (Socket AM3+)


Testing Setup: Intel Socket 2011 V-3


Testing Setup: Intel Socket 2011


Testing Setup: Intel (Socket 1150)



Overclocked settings:

  • Processor: AMD FX-8370 5092MHz   204.7 x 24.5
  • Processor: AMD FX-8370E 4990MHz  203.7 x 24.5


It seems the break point for these two processors is right around the 5GHz mark, much like what I saw with the FX-9590 and FX-9370, even down to the voltages used to reach the final clock speeds. Let's start with the FX-8370E. For a quick and dirty start, I employed the BIOS save file I had for my FX-8350, which was a solid IBT-stable 4.7GHz clock speed save file. I rebooted the system and sure enough this energy conscious chip responded with perfect stability at a much cooler operating temperature than the FX-8350. Applying a bit more voltage, it was able to post at 5.2GHz, but anything over 1.525v would not boot the system. As such, the day in day out setting for the FX-8370E is more along the lines of 4.99GHz using up to 1.5v. It will run that speed with as little as 1.475v, but is not fully stable at that point.

The FX-8370 got the same treatment, but I started with the 5.067GHz setup that I used to get the FX-9590 stable at over 5GHz, and the FX-8370 posted and ran benchmarks, just without any repeatable stability. To get fully stable at this speed required more voltage than the Corsair H100i could shed before throttling the clock speed. Backing down to 5.015GHz at 1.475v got the FX-8370 fully stable and gets the chip right in the 5GHz range for less coin than the FX-9590. Comparing the voltage applied for both chips, it's clear that the same overclocking experience will get you pretty close to the maximum clock speed using an AIO liquid cooling solution. Air cooling is going to lower your overclocking margin just due to the heat these chips will shed when overvolted.
