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.

Would it be worth putting the gaming tests first? Perhaps for the mid range CPUs, it makes more sense.yannigr2 - Wednesday, May 13, 2015 - link
Much more expensive i7 and i5 in the charts and wrong higher-older prices on AMD APUs. Am I wrong?Please, I am NOT asking you to make AMD APUs look good, don't make it look like that, just do not make them look awful. You want to add a much more expensive i7, at least change the color of the line, do it black or something. Even the i5 is much more expensive than the APUs especially considering that AMD changed it's prices a few days ago, which means that the AMD prices on the charts are also wrong. 7850K's price that is the most expensive is $127 not $173.
From the five Intel processors you have in the charts only three of them are at the same price range as the APUs. Some Intel prices are the tray prices, not the box, and most of them are the prices on Intel's site. AMD prices on the other hand are the old much higher prices. Even in your article you give lower prices than those on the charts. AM I WRONG?
Accept the critic when it is fair, don't try to make the other guy look like a brainless fanboy who asks you to make AMD APUs look good by putting GPU test first.

What is being benchmarked are APU's; AMD's integrated graphics processors.akamateau - Tuesday, May 12, 2015 - link
I comment becasue they are JUNK. I read them hoping that Anand will write something useful.I am also settting the record straight and I am challenging ANANDTECH to write the truth.

You sound like a paid shill with all your whining.Maybe AMD could hire shills with better English grammar.

That's an insult to paid shills. No one being paid to shill for a company would act that obnoxious and incoherent. Looks more like a volunteer effort, or someone who deliberately wants to make vocal AMD supporters look obnoxious and incoherent.akamateau - Tuesday, May 12, 2015 - link

Review says that it's 720p benchmark, but screenshot is 1080p. Normally I wouldn't care, but screenshot even shows number of FPS. What is wrong?Ian Cutress - Tuesday, May 12, 2015 - link
I use the same screenshot in all the games on the other pages where I am testing 1080p. It's just a generic screenshot of the game showing what happens in the benchmark.lilmoe - Tuesday, May 12, 2015 - link
Too painful to watch. I just hope things getter better in 2016-17
