The AMD A8-7650K APU Review, Also New Testing Methodology

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.
Photoscan prefers full threads and high IPC, so the low end i3, AMDs APUs and the G3258 all perform within a similar margin.
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.
Despite the single thread performance, in multithreaded the gap between Pentium, i3-T, APU and i3 is similar to that seen in Photoscan.
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.
It's a similar story here, especially when we bring up 4K encoding in Handbrake. The APUs outperform the G3258 and the more expensive i3-T, but the i3-4330 is marginally quicker.
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 comments assume that ANAND provided benchmarks using DX12 and they did not. ALL of the GRAPHIC benchmarks were with either synthetic benchmarks or game benchmarks using DX11.DX11 cripples the performance of ALL APU's, IGP and dGPU. Draw calls ARE a measure of CPU-to-GPU "bottleneck" or elimination thereof. You can not render a polygon until you draw it.
DX12 enables CPU core scaling; basically increased draw calls are a function of the amount of multithreaded cpu cores. DX11 does not allow multithreeaded gaming.
DX11 may be current but why should I base hardware purchases from testing based on obsolete software AND benchmarks?
DX12 will be in widespread use by game developers by Christmas.
Anand has psent quite a bit of time and money testing hardware on obsolete benchmarks TO WHAT END?
Starswarm and 3dMArk API Overhead Test are available but ANAND ignore them.
Why?
AMD's APU was designed to FLY using Mantle and DX12. It is not AMD's fault that Intle IGP is so poorly designed. That is Intel's problem.
Test Intel IGP using the latest API and you will see. Comaparatively test AMD and Intel using obsolete benchmarks with DX11 and ANAND is lying to the consumer and can not be trusted.
AN unbiased and well balanced piece should use legacy benchmarks, they should also use the very latest available. ANAND di not do this.

"Starswarm and 3dMArk API Overhead Test are available but ANAND ignore them.Why?"
Because they want to hide the truth. "It is hard for a person to wake if he is asleep because he pretends to be asleep but infact he is not. He just want to fool you because of his stupidity"
The refusal to support the upcoming DX12 give as hint that the review is biased and something fishy going at the backdoor. I am not an IT guy and new on this site but i could easily detect what is the difference between biased and unbiased review.
The reviewer and Anadtech guys for sure are all intellegent guys but they allowed themselves to be succumed by their own personal interest.

Or its just something as simple as DX12 not being released yet, the performance is likely to change, so is an invalid test for comparing hardware at this time. The benchmarks you refer to are only valid as a preview for potential gains.akamateau - Tuesday, May 12, 2015 - link
Windows 10 with DX12 will be released in less than 2 months. Mantle is final and DX12 is final. Anand has it but ignores it.By Christmas ALL new games released will be DX12.

DX12 may not be final. API probably is, runtime is likely close, drivers likely won't be.And you're delusional if you think all new games released at the end of this year will be DX12. It takes years to develop a AAA game, so they would need to have started before DX12 was available. The market for DX12 will be tiny by Christmas as DX12 will be Windows 10 only. Not everyone will be willing or able to upgrade the OS. Not all hardware even supports DX12. You're completely ignoring the history of previous DirectX roll outs.

Ah, so basically the choice is buy an AMD APU and get shoddy performance now, and great performance in a year, or buy an Intel/Intel-Nvidia solution and get great performance now and great performance in a year!So theres really no reason to get the AMD is what you're saying?
JumpingJack - Tuesday, May 12, 2015 - link
I will bet you what ever you make in a year that not all games released between DX12 release and christmas of this year will be DX12 native.akamateau - Tuesday, May 12, 2015 - link
@Ian Cutress"as well as having parallelizable code"
ARE YOU NUTS?
You really need to cut the crap.
Mutlthreaded gaming will come as a result of DX12 and Asynchronous Shader Pipelines and Asynchronous Compute Engines.
galta - Tuesday, May 12, 2015 - link
I don't think he is nuts, but you seem a bit angry.From a CPU perspective, multithreaded games need not wait for DX12. They could have been written before.
Anyway, we have a clear statement of you: DX12 will make AMD shine. We should talk again on Christmas.
Just keep in mind that the same was said when DX11 was about to be released, with known results...
