Sapphire A75 Pure Platinum Review

» Discuss this article (3)


Testing the AMD A8-2950 APU will include running it and comparison product(s) through the OCC test suite of benchmarks that includse 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


Comparison Boards:

  • Gigabyte A775M-UD2H




Overclocked Settings:

  • Processor: AMD A8-3850 at 138MHz x 28

Overclocking the Llano is slightly different, so I wasn't entirely sure what to be expecting. One thing I noticed right away is that at the stock 29 multiplier my hardware would go unstable at almost any BCLK increase. Dropping the multiplier down to 28 fixed this problem instantly. I was than able to increase the BCLK in nice 10MHz increments until 140MHz where I couldn't boot to windows. Dropping down the frequency to 138MHz allowed me to boot, and get through OCC benchmark suite, and remained stable. As for how decent of an overclock it was, after looking around the net I decided that this is a fairly decent overclock. However, I have not yet used enough A75 motherboards to know if the Sapphire A75 Pure Platinum unlocked all the potential from my chip, or if it just did an average job. At this time, I'm willing to give it the benefit of the doubt.
