The Kaveri Refresh 'Godavari' Review: Testing AMD's A10-7870K

Agisoft Photoscan – 2D to 3D Image Manipulation: link
Agisoft Photoscan creates 3D models from 2D images, a process which is very computationally expensive. The algorithm is split into four distinct phases, and different phases of the model reconstruction require either fast memory, fast IPC, more cores, or even OpenCL compute devices to hand. Agisoft supplied us with a special version of the software to script the process, where we take 50 images of a stately home and convert it into a medium quality model. This benchmark typically takes around 15-20 minutes on a high end PC on the CPU alone, with GPUs reducing the time.
Cinebench R15
Cinebench is a benchmark based around Cinema 4D, and is fairly well known among enthusiasts for stressing the CPU for a provided workload. Results are given as a score, where higher is better.
HandBrake v0.9.9: link
For HandBrake, we take two videos (a 2h20 640x266 DVD rip and a 10min double UHD 3840x4320 animation short) and convert them to x264 format in an MP4 container. Results are given in terms of the frames per second processed, and HandBrake uses as many threads as possible.
Hybrid x265
Hybrid is a new benchmark, where we take a 4K 1500 frame video and convert it into an x265 format without audio. Results are given in frames per second.

Your words are sage indeed sir. Reading them in 2019 it is clear how right you are. Of course your suggested combo is better buying for gaming performance.Cryio - Monday, June 1, 2015 - link
8320E? That's almost as expensive as the 8350.The best bang for the buck in AMD's portofolio is the 8300. Yes, you've read that right, 8300. Same TPD as the 8320E with some frequencies, same overclock capabilities and for 20% cheaper. It's only slightly more than an FX 6300.

The 8320E is $100 from Microcenter.Cryio - Tuesday, June 2, 2015 - link
Then awesome. But generally, the 8300 is the cheapest you can buy.Dresdenboy - Monday, June 1, 2015 - link
What is the BIOS version being used? And what was the voltage?According to CPU World there might be heavy throttling with a somewhat older BIOS. The newer version fixes the problems:
"Update (May 31): Throttling problem was fixed by upgrading to P2.60 BIOS. Thanks to Roger Harshman for the hint! The processor is stable now, and runs CPU benchmarks and games without throttling and lockups. By the way, new BIOS sets lower core voltage, close to 1.45V."

The only thing that saddens me is that on average, the iGPU in the 7870K is still just 3 fps faster on average than a 240 DDR3.On paper, the iGPU should be as fast as a 7750 GDDR5 ! Not to mention the iGPU is based on GCN 1.1.
But for whatever reason, it's still 50% slower than it should be.

No, it has the same number of shaders as the 7750, but lower clocks, less bandwidth, and a limited thermal envelope. I don't know why you think it should be as fast as the 7750.Cryio - Monday, June 1, 2015 - link
Same number of shaders (both have 512), indeed lower clocks but newer architecture which should compensate for deficiencies.Plus 2400 DDR3 dual channel should allow it all the bandwidth in the world.

Nope. GDDR5 is immensely better than any DDR3 on the planet, plus the APU has to throttle back due to the TDP constraints. NO WAY it will reach a 7750. the newer architecture isn't much faster, the main improvement are the added features.fallaha56 - Monday, June 1, 2015 - link
where is a DX12 preview? this is what is really needed to see which chip is the one to get...
