AMD Kaveri Review: A8-7600 and A10-7850K Tested
by Ian Cutress & Rahul Garg on January 14, 2014 8:00 AM ESTCPU Performance: Continued
Xilisoft Video Converter 7 - link
The XVC test I normally do is updated to the full version of the software, and this time a different test as well. Here we take two different videos: a double UHD (3840x4320) clip of 10 minutes and a 640x266 DVD rip of a 2h20 film and convert both to iPod suitable formats. The reasoning here is simple – when frames are small enough to fit into memory, the algorithm has more chance to apply work between threads and process the video quicker. Results shown are in seconds and time taken to encode. XVC also offers acceleration via CUDA and AMD APP, so if these are available on the CPU we offer results with and without.
With large frame data, the IGP on Kaveri does not particularly help much.
For smaller frames however, there is an advantage to enabling the AMD APP function.
HandBrake v0.9.9 - link
For HandBrake we do the same files as XVC but convert them into the default format Handbrake offers upon loading the software. Results shown are in Frames Per Second.
Handbrake loves cores, threads and MHz
Adobe After Effects 6
Published by Adobe, After Effects is a digital motion graphics, visual effects and compositing software package used in the post-production process of filmmaking and television production. For our benchmark we downloaded a common scene in use on the AE forums for benchmarks and placed it under our own circumstances for a repeatable benchmark. We generate 152 frames of the scene and present the time to do so based purely on CPU calculations.
7-Zip 9.2 - link
As an open source compression tool, 7-Zip is a popular tool for making sets of files easier to handle and transfer. The software offers up its own benchmark, to which we report the result.
PovRay 3.7 - link
PovRay historically loves threads, MHz and IPC. The standard benchmark from PovRay is what we use to test here.
TrueCrypt 7.1a - link
TrueCrypt is an off the shelf open source encoding tool for files and folders. For our test we run the benchmark mode using a 1GB buffer and take the mean result from AES encryption.

Kind of funny to hear "Iris" mentioned here given that the SGI O2 was an early example of a workstation with HUMA back in the mid-90's. :) There was no such thing as GPGPU back then (it might have helped save SGI if there was), but it provided a big help for memory-intensive things like texture-mapping.vinayshivakumar - Thursday, January 16, 2014 - link
Why are the iGPU codenames mentioned in the CPU benchmark and the CPU is in brackets ?? What is the reason to mention the GPU at all in a CPU test ? To the untrained eye , it might look as is HD3000 is faster than the AMD R7... Which is obviously not true...vinayshivakumar - Thursday, January 16, 2014 - link
Am I missing something here , apart from a bias ?Th-z - Thursday, January 16, 2014 - link
I agree the labels can be misleading, in CPU benchmarks other than the second table "Agisoft PS v1.0 Mapping IGP" on page 10, all other are done with CPU only. Some tables got it right while some have iGPU names leading the labels and model names in the brackets. What should be in the brackets are iGPUs. Consistency in labelling is needed. It's probably not intentional, just a result of messing up the labels and get the review out ASAP.ryrynz - Thursday, January 16, 2014 - link
You should be listing the GPU first in the Winrar results. The GPU is obviously not important in this benchmark and really shouldn't be specified at all.sonofsanta - Thursday, January 16, 2014 - link
"...the benchmark follows Jenson Button in the McLaren who starts on the grid in 22nd place, with the field made up of 11 Williams cars, 5 Marussia and 5 Caterham in that order."You sure a 2013 McLaren could make it through that field? I reckon it'd still fail to make the podium.

What's the story with Iris Pro and huge difference between average FPS and minimum FPS?In BI performance test: 78 average and 6 minimum, quality test: 20 average and 1 minimum.
If this is happening during gameplay this makes game almost unplayable. AMDs lineup has much smaller variance.
It would be nice to see time frame tests.

What a disappointment... I thought the 7850K would be the first rig I've built in years but it's barely an improvement over the 6800 and still no match for an i5 :(Rogatti - Thursday, January 16, 2014 - link
Drivers still immature ... I will wait to form an opinionSolMiester - Thursday, January 16, 2014 - link
WOW, looks to me that the A10 6800k is the better bang. I saw only 1 game where the R7 bettered the 6800K where any of them were playable....
