Benchmarks

System setup

Below is a complete set of AMD A10-7850K and A10-7870K benchmarks from our CPU benchmark database. Both microprocessors were tested on ASRock FM2A88M Extreme4+ motherboard with 16GB dual-channel G.SKILL RipJawsX DDR3-2133 F3-2133C9D-16GXH memory, and Integrated on-chip Radeon Rx graphics.

All tests were performed at default frequency and voltage, using manufacturer's stock fan/heatsink. None of the components were overclocked. Motherboard BIOS options were left at default settings.

The results of all benchmarks are broken into four categories: multi-threaded, single-threaded, memory intensive and graphics / gaming.


A10-7850K vs A10-7870K single-threaded benchmarks

Single-threaded benchmarks run on a single CPU core, and do not depend on such features as the number of cores, or Hyper-Threading technology. Additionally, they do not utilize on-chip caches, dedicated to other cores.

A10-7850K vs A10-7870K graphics benchmarks

Graphics benchmarks depend on the type of integrated or discrete graphics adapter, and to less extent on the processor performance. Because these benchmarks are synthetic, they may not truly represent gaming performance. However, they still can be used to estimate whether one processor will perform faster or slower than another CPU in games and other 3D tasks.

Had both on the same hardware setup

One thing I noticed, is the A10-7870k says much cooler. Not sure why. I had my fans set to silent on both CPU's, but the 7850k packs a lot of heat and constantly required the CPU fan on high. They both use the same OEM heatsink and fan, so I can't figure that one out. Also, my 7850 used Arctic Silver compound, while I am using the provided heatsink compound with the 7870.

I noticed improvement in CPU performance in games. The 7870k seems to perform on par and net me identical performance as my old 8-core FX8150, at their default clock rates. I even moved my graphics card over to my wife's PC, which now houses my old FX, runs Windows 10, the same AMD 16.1 hotfix drivers and has a Gigabyte mATX board, where mine uses the Gigabyte ITX board. I ran Star Citizen on her PC, which is very CPU intense, used the same graphics configuration file that I use for Star Citizen on my mini-ITX gamer, at the exact same resolution and graphics quality, with the same AMD control panel settings and I get slightly better performance and even frames with my 7870k. However, if I run Cinebench, the FX trashes the 7870k in bench scores. This tells me that heavily threaded applications tip in favor of my old FX. Games seem to lag behind in utilizing multiple threads and more or less cater towards quad core CPU's.

7870k comes with a stronger cooler from the FX cpus that has a copper core, not aluminium anymore.
