AMD A10-7850K Kaveri APU Processor Review
To start off the benchmarking session, I started off with Aida64 Engineer. The AMD A10-7850K fairs well against the A10-6800K. There is a little back and forth but over all the 6800K enjoys a slight advantage due to the increased clock speed.
Next up I ran the memory & cache benchmark within Aida64. The memory bandwidth has been improved with the A10-7850K.
Next up, Cinebench R10. The 6800K leads in the single core benchmark but makes up some ground with the multicore benchmark. One anomaly with this benchmark was the A10-7850K just couldn’t surpass the 6800K in the OpenGL benchmark.
Cinebench R11 shows a pretty even battle between the 7850K and the 6800K.
In Luxmark, the 6800K takes a slight advantage in the CPU only tests. The R5 series integrated GPU really stretches out the lead over the older 6800K. Adding the CPUs back into the mix the 7850K with a few more compute units is able to maintain the lead.
The speed advantage the 6800K holds over the 7580K is erased in the Wprime 32M test.
Moving out of synthetic testing, first up is Handbrake. Handbrake is a video encoding software. To test, we took a 101 MB MPEG 2 video vile and encoded it to an MP4 file. Default settings were used in the software. There is virtually no difference between the two processors with the 6800K leading by 1 second.
With WinRAR, we used the built in benchmark. We let the benchmark run for 1 minute and recorded the reported speed at the time. Here the 6800K leads due to the increase in speed over the 7850K.
In this review, I do a VERY LIMITED over clocking test. In the next series of tests, I bumped the speed of the 7850K to match the 6800K. Turbo core was turned off in the BIOS. The CPU speed was set using a 41 multiplier with 100 Mhz base clock. I did this to level the playing field and test IPC clock for clock between the two processors.
Moving back into the synthetic tests, we can see with both processors at 4.1 Ghz, the A10-7850K performs better than the 6800K, which should be expected when comparing current generation technology with the previous generation.
Testing WPrime at 4.1 GHz yielded a 1.2 second advantage over the previous result with the 7850K and a 4.7 second lead over the 6800K at the same clock speed.
Our score in handbrake improved as well. At stock clock speed, 3.7GHz for the 7850K, there was only a 1 second advantage for the 6800K. With both processors running at 4.1 GHz, the AMD A10-7850K pulls a head with a 4 second advantage.
With WinRAR we see that the AMD A10-7850K takes the lead. This should show that AMD has made IPC improvements over the previous generation 6800K.
