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.

Both the 860k and the 870k are steamroller CPUs.They're pretty much the same.

Yep.Either 750 Ti and a 860K OR
260X and an i3.
Same performance, same cost.

The 260X (and radeon GPUs in general) don't do well with dual cores, as proven by digital foundry. It looks like their DX11 drivers are having problems.You could go i5 + 260X for just a bit more than i3 + 750ti, and have way better performance.

Would such cpu only processors be any faster than the equivalent APU?ie. - are there any performance or other downsides to having the integrated gpu?
as in, if you had an apu anyway, are there advantages for a dgpu rig to swap processors?

But this is a dual core. A dual core with CMT, which even AMD admits has failed and is dumping for Zen.It can only run two floating point threads.

There are no separate integer and floating point threads. AMD's 870K can run four threads, end of story. It has four 128-bit FMAC's, so I don't see your point.nikaldro - Monday, June 1, 2015 - link
The point is, the 860k has 4 ALUs but only 2 FPUs.Jimster480 - Tuesday, June 2, 2015 - link
It has 4 128-bit FMAC's (FPU's) which can combine to make 2 256b FPU's.It can process 4 normal floating point threads or 2 AVX threads.

Try playing crysis 3 or any game with actually suffer with a 2 core cpu (worse without ht). Crysis 3 on pentium are a nice stop motion experience, 4 secs of game then half a second of stutter.nikaldro - Monday, June 1, 2015 - link
Games like that are a lag fest on an 860k too, wich is pretty much the same as this APU's CPU.If you wanna play that kind of games, you don't even think about a 400$ budget build.
