CPU-Z and GPU-Z

On the left we see the A10-6800k which is clocked at an impressive 4.1 GHz out of the box and can jump up to 4.4 GHz with Turbo Boost. On the right is the 6700 which has slightly lower clocks at 3.7 and 4.3 GHz base and boost speeds respectively. Aside from the obvious clock speed change, the difference between these two chips is that the 6800k is unlocked meaning the multiplier can be adjusted up for overclocking and the 6800k supports faster memory speeds (2133 MHz versus 1866). The 6800k also has a higher TDP at 100W compared to the 6700’s 65W.

Both the 6800k and the 6700 have the same exact GPU, a Radeon HD8670D clocked at 844 MHz with 384 shaders.

Cinebench


6800k	6700	5600k

Cinebench tests a systems CPU performance through rendering a complex 2D scene utilizing every core. The 6800k showed a 4% increase over the 6700 due simply to the clock difference between the two chips and both chips showed a fairly significant increase over last generations A8-5600k.

SiSoft Sandra


6800k and 6700	5600k (stock and overclocked)

SiSoft Sandra is a tool capable of testing just about every part of your system. I focused on two CPU intensive benchmarks, arithmetic processing, and multi-media performance. In the arithmetic processing benchmark the 6800k averaged about a 6% increase over the 6700 and a 15% increase over the 5600k at stock clocks. Even when the 5600k is overclocked to the 6800k’s level, the 6800k still beats it by around 4%.


6800k and 6700	5600k (stock and overclocked)

In the multimedia benchmark the 6800k beats the 6700 by about 6% and the 5600k by 14-15%. Again even when overclocked the 5600k still gets beat by a few percent.

x264

x264 is a benchmark that measures how fast your PC can encode 1080p video into the x264 format. On the first pass the 6800k and 6700 averaged 34.62 and 32.07 fps respectively. On the second pass they averaged 7.93 and 7.94 respectively. Overall we saw about a 6-7% increase from the 6700 to the 6800k. The 5600k was about 9% behind the 6800k.
