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.

Although why would u want to go the Nvidia route if you have an APU? Why would you want to do dual vendor? The 750 isnt a good value so it only makes sense in applications that need to have a power sipping GPU.RussianSensation - Monday, June 1, 2015 - link
The suggestion of getting a stand-alone budget CPU and a GPU is sound but your recommendation for GTX750 is not. That line is garbage for games for the price.R9 270X costs $125 USD and is 44% faster than a GTX750Ti, which means > 50% faster than GTX750. If gaming is the primary consideration on a budget, under no circumstances should a budget gamer pick a 750/750Ti over the nearly 50% faster $125 270X:

I know that, but apparently the 260 and 270 line simply don't work well with intel dual cores, as digital foundry found out.meacupla - Monday, June 1, 2015 - link
After playing around with a Pentium G3258, I can clearly say that you're better off with 4 cores, even if 2 of them are virtual.There are now plenty of programs and games that will use up more than 1 thread.

2 haswell cores are just as fast as 2 steamroller modules (wich, i remind, aren't really 4 actual "cores") in multithreaded tasks, and the pentium is MUCH better in single threaded tasks.As for the GPU, the 750 is way better than the APU's iGPU.
It's either a tie or a win for my combo in 90% of the situations.

You'll see. The issues with dual cores crop up when those two cores somehow get maxed out or one of them maxes out. 2 cores + 2 virtual cores just has better overhead when one of them gets maxed out.nikaldro - Monday, June 1, 2015 - link
An APU dooesn't have virtual cores. Maybe you are confusing their design with intel's hyperthreading.basically, an APU module is composed of 2 ALUs but only one FPU, so a dual module APU, like this one, does ok in ALU heavy workloads but just fails in FPU heavy ones.
And if a workload can "max out" 2 haswell cores, it sure as hell will kill 2 steamroller modules in almost all cases.
With the pentium you have equal multi thread performance and better single thread performance, as well as a better GPU.

Try crysis 3 on the pentium and the 870K, use the same dedicated gpu 750, 260, 980ti is you want. With just 2 cores youll get an stutter festival, IPC means nothing when the game actually demand core resources.nikaldro - Monday, June 1, 2015 - link
IPC IS core resources.If core count was all that mattered, we'd use ARM octacores.

...or AMD FX 8xxx CPUs. Sadly, reality is a mixture of IPC and core count.
