Testing:

Testing the AMD A8-2950 APU will include running it and comparison product(s) through the OCC test suite of benchmarks that include both synthetic benchmarks and real world applications to see how each of these products perform. The gaming tests will also include both synthetic benchmarks and actual game play to see if similarly prepared setups offer any performance advantages. Instead of leaving the gaming tests to a discrete video card, the gaming prowess of the IGP will get a small workout as well. The APU will receive a fully updated fresh install of Windows 7 Professional 64-bit edition and I've used the latest drivers for each board and the latest AMD Catalyst drivers for the XFX HD 6970. To ensure as little variables as possible, all hardware will be tested at their stock speeds, timings, voltages and latencies - unless otherwise stated.

 

Testing Setup: AMD Socket FM1

 

Testing Setup: Intel Core i5/i7 Socket 1155


 

Comparison Boards:

  • Intel Core i7 2500K

 

 

Overclocking:

Overclocked Settings:

  • Processor: AMD A8-3850 at 125MHz x 29

The AMD A8-3850 APU has a locked multiplier so there is not much you can do in the way of easily raising the multiplier while keeping the rest of the system at stock speeds. I went into overclocking by raising the reference clock little by little and upping the voltage a bit at a time to keep stability. I found that anything over 1.48 volts caused the processor to heat up very quickly which caused the system to throttle down to keep the hardware from burning up. But, it never blue-screened. To compensate, I had to keep the voltage under 1.48 volts and milk it as much as I could. I was able to get the reference clock up to 125MHz before losing stability. With the multiplier at the stock 29x, that put me at a total of 3.625GHz speed. Not bad for a little chip like this. As a by-product, the memory was able to reach 2000MHz with no issues on the platform.
