The AMD A8-7670K APU Review: Aiming for Rocket League

Agisoft PhotoScan – 2D to 3D Image Manipulation: link
Agisoft PhotoScan creates 3D models from 2D images — a process that 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 achieve the best performance. 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 to 20 minutes on a high-end PC on the CPU alone, with GPUs reducing the time.
PhotoScan shows most APUs performing around 41 to 42 minutes, which suggests that there is a bottleneck in the core design.
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 a video (a 2h20 640x266 DVD rip) and convert it 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.

Where is the i3-6100 in those gaming tests?Ian Cutress - Wednesday, November 18, 2015 - link
We haven't had one in to test.Samus - Wednesday, November 18, 2015 - link
Yeah, my guess is the i3-6100 is going to render AMD's entire A-series irrelevant (unless you're looking for a sub-$100 chip) simply because of it's DX12 iGPU + DDR4. Early reviews show it to be around 15% faster than the i3-4130 in single threaded performance alone.tipoo - Wednesday, November 18, 2015 - link
No option for dual graphics with a cheap Radeon though, you'd have to wait for DX12 Multiadaptor to take off, if it does.Samus - Wednesday, November 18, 2015 - link
That's true. AMD still has their niche features. But I suspect Intel's 500-series IGP is going to be pretty strong against 6 of AMD's compute cores based on DDR4 bandwidth alone. Will have to wait for the review, obviously.hojnikb - Thursday, November 19, 2015 - link
Why bother with dual graphics at all ?Just buy a beefier card and an athlon x4.
Unless you hit the right combo, hybrid crossfire will be a mess.

Intel needs to work on their drivers, their current ones are a real mess. I feel like if they improved their drivers they might actually get to the point you're talking about where you could buy a system with Intel graphics for light gaming, but right now it's a really poor experience.tipoo - Wednesday, November 18, 2015 - link
AMDs APUs seem more bandwidth constrained than limited by themselves. I hope they take HBM2 as an opportunity to provide at least a PS4 equivalent GPU in an APU in the coming years.Refuge - Wednesday, November 18, 2015 - link
They don't plan to bring HBM to their APU's anytime soon from the product slides that they released with their HBM announcement.tipoo - Wednesday, November 18, 2015 - link
Yeah, that's why I gave it a longer time frame. It's going to be high end GPU exclusive for a while, but I hope the trickle down comes fast enough. Or if not, go eDRAM.
