CPU Performance

I jumped right into benchmarking with the A10-7800. To start things off I jumped into the CPU performance side of things. The onboard GPU is exactly the same as the 7850K so I really wanted to see how much of a difference the slight clock speed difference would make. Additionally after our 7850K review I added PCMark 8 to get a better idea of how well the 7800 would handle real world tasks using OpenGL and without OpenGL. Not surprisingly the 7800 came in behind the 7850K in all of our benchmarks. In X264 HD its performance was down near the A10-6800.

Cinebench is still one of if not my favorite CPU benchmark because it gives me a chance to test the overall CPU as well as a single core. This is a great way to see how well the actual architecture performs as well as compare performance between 6 and 8 core CPUs versus 2 and 4 core CPUs. In this care the overall CPU came in just barely under the 7850K as expected. The single core test was hit a little harder, it’s obvious that Kaveri relies on clock speed to really push things.

The Passmark CPU score showed once again that the 7800 performed just barely under the 7850K. This is an interesting test because some of the older APUs actually perform better than both Kaveri APUs. With this chip performing like its big brother, it shows that this is an architecture issue or drive issue, not a fluke in our testing.

PCMark 7 had a little bit larger difference between the 7850K and the 7800 than our other tests. Enough for the 980X to slip past. That really goes to show you how much things have improved. The 980X is a 6 core monster CPU that cost $1,000 when new and the 7800 is getting nearly the same numbers in this benchmark with a MUCH lower price. In PCMark 8 the performance difference between the I7-4790K and the A10-7800 wasn’t as big as the price difference might imply. We will have to get more testing to really see what the results mean.

wPrime tells the same store on its 32M benchmark with the 7800 performing just under the 7850K.

Okay now we are talking, in 3DMark Fire Strike the A10-7800 came in at the bottom of the charts, but that is when compared to a stack of Intel CPUs that cost up to 7 times as much.

You can expect a one to two FPS difference between the Kaveri APUs. More importantly, three of our the four games tested really didn’t show a big difference at all between the much faster CPUs and the budget A10-7800. Hitman: Absolution did hit the CPU hard though with it making a HUGE difference in performance. Most games are GPU limited though, as long as most of the games you play fall into that category you could easily get the same gaming experience with the A10-7800 as you would a $400 or $1,000 CPU.

For those of you who are thinking about building an HTPC or a SFF build the A10-7800 might fit the bill, check it out!
