Benchmarks

Test System

AMD A10-6800k
ASRock FM2A85X Extreme 6
Corsair H100

We decided to test the memory using just the 6800k with no discrete GPU to demonstrate the improvements faster memory has on these new APUs. The memory was tested at stock speed and then downclocked to 1600 and 1333 MHz to compare the results.

CPUZ

In CPU-Z we see that our memory is clocked at 1866 MHz with the timing set at the stock 10-10-10-30 at 1.5v. The timing on this memory is quite loose compared to similar kits which are around 9-10-9-28 at the same voltage.

3DMark


1333 MHz	1600 MHz	1866MHz

The new 3DMark benchmark stresses both the GPU and CPU heavily and should show a significant gain from increased memory speeds.
At the downclocked 1333 MHz our Ballistix allowed the 6800k to score a 5043 in the Cloud Gate benchmark and 823 in Fire Strike. Bumping the speed to a still downclocked 1600 MHz gave us a 10-11% increase and finally bringing the RAM to the stock 1866 MHz speed gave us an extra 6-7%. Simply increasing our memory speed netted us around a 17% increase overall which is quite significant.

3DMark 11


1333 MHz	1600 MHz	1866MHz

3DMark 11, like the new 3DMark, stresses both CPU and GPU, focusing specifically on DirectX 11 features.
Our score of 1385 at 1333 MHz increased to 1510 at 1600 MHz, giving us an 8% gain. Bumping the speeds to the stock 1866 increased our score 14% over 1333, giving us a final score of 1616.

Unigine Heaven


1333 MHz	1600 MHz	1866MHz

Unigine Heaven is a graphically intensive DirectX 11 benchmark that heavily stresses the GPU as well as the CPU.
At 1333 MHz our average fps was 9.2. Increasing the speeds to 1600 bumped that average up to 10.4, and finally bringing it to the stock 1866 we were able to pull 11.6 fps. Now this might now seem like much considering the fps itself is so low, but comparing the numbers to each other we see that increasing our RAM speed from 1333 to 1866 gave us a massive 20% increase.

DiRT 3


1333 MHz	1600 MHz	1866MHz

DiRT 3 represents a mid-level graphically intensive game which we ran at the high preset.
Our 6800k with memory clocked at 1333 MHz was able to pull an average fps of 22.7. Jumping up to 1600 MHz added another 3.5 fps and moving up to 1866 added another 2.8 fps to our average. Going from the downclocked 1333 MHz to the stock 1866 MHz netted us an impressive 21% increase.

Bioshock Infinite

Bioshock Infinite is the newest title in the popular Bioshock series and is fairly graphically intensive. We ran the built-in benchmark at the Ultra preset.
Although the 6800k struggled at such a high preset without a discrete GPU, we can clearly see that as the memory speed increased the fps increased as well. Going from 1333 MHz to 1866 we see a 16-17% increase to both our average and minimum fps.
