AMD A10-5800K & A8-5600K Review: Trinity on the Desktop, Part 2
by Anand Lal Shimpi on October 2, 2012 1:45 AM ESTVideo Transcoding Performance
x264 HD 3.03 Benchmark
Graysky's x264 HD test uses x264 to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
CPU based video transcode performance is as good as it can get from AMD here given the 2/4 module/core setup of these Trinity APUs. Intel's Core i3 3220 is a bit slower than the A10-5800K. We're switching to a much newer version of the x264 HD benchmark for our new test suite (5.0.1). Some early results are below if you want to see how things change under the new test:
| x264 HD 5.0.1 Benchmark | ||||
| 1st Pass | 2nd Pass | |||
| AMD A10-5800K (3.8GHz) | 33.5 fps | 7.41 fps | ||
| AMD A8-5600K (3.6GHz) | 32.2 fps | 7.12 fps | ||
| Intel Core i3 3220 (3.3GHz) | 35.2 fps | 6.61 fps | ||

That seems to be a big if rather than a matter of when, though, given the patchy support that's been forthcoming for QuickSync so far! So possibly a valid avenue of investigation anyway. :)eBombzor - Tuesday, October 2, 2012 - link
Am I missing something in the benchmarks? Tom's did a CPU comparison with the 2100 and the 8120 (which isn't a whole lot different from the 8150) and the 8120 is near the Phenom CPU gaming wise.http://www.tomshardware.com/reviews/gaming-fx-pent...
Something is not right here, the 2100 dominated the 8120 in Tom's benchies, the 3220 should be better.

Just thumbing through Tom's article, it looks like they're using 1920x1080 with high quality settings (GPU-limited settings) while we're mostly using 1024 and 1680 in order to ensure we're CPU-limited.Rezurecta - Wednesday, October 3, 2012 - link
Who cares about CPU limiting? You're not going to play a game @ 1024. 1680 might be valid, but why not show benchmarks at 1920? It just doesn't make sense to show a benchmark that isn't at a major demographic point.It could be a very misleading benchmark for a substantial amount of readers.

But it makes amd look better, so it's awesome, and irresistible.Rand - Tuesday, October 2, 2012 - link
Why was the overclocking test done on Windows 8 (Image shows Win8), while the performance testing was done on Windows 7 (Test setup lists Win7)?nofumble62 - Tuesday, October 2, 2012 - link
This Trinity performance didn't beat i3, let alone i5.AMD statement " i5 performance at i3 price" is a total lie.

It's only true for heavily threaded integer work and AES...But yeah, disappointing...

Legit reviews state that AMD advised them to disable turbo mode else it will throttle the overclock. They were able to overclock it to 4.6 with full stability using a larger cooler.http://www.legitreviews.com/article/2047/18/
