DivX 6.8.5 with Xmpeg 5.0.3
Our DivX test is the same DivX / XMpeg 5.03 test we've run for the past few years now, the 1080p source file is encoded using the unconstrained DivX profile, quality/performance is set balanced at 5 and enhanced multithreading is enabled.
Thanks to AMD's Turbo Core the Phenom II X6 is pretty close here, but still not able to topple Intel's Core i5 and i7.
x264 HD Video Encoding Performance
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.
And we finally see the Phenom II X6 flex its muscle, even the 1055T is faster than the Core i7 860:
In the actual encoding pass the 1055T falls behind the 860 but it's still a good 19% faster than the Core i5 750.

I think people buying an Extreme Edition CPU know exactly what they're getting themselves into.Those CPUs are never good price/performance, you pay a premium to get the absolute fastest CPU on the market, that's the whole point of the Extreme Edition concept.
Obviously Intel isn't going to offer only one expensive 32nm six-core forever. Perhaps this X6 CPU will trigger Intel to release more 'mainstream' six-cores and other 32nm CPUs.

For home use, yes. For professional use, that 48.8 frames/second on the 980x vs. 28.5 on the 1090T, for x264 2nd pass encoding, looks quite justifiable. If that's your business, that'll pay for itself in a couple of weeks..

Point taken. I was speaking for home users. ;)pow123 - Wednesday, May 5, 2010 - link
Exactly. A few seconds. I will not pay for an over priced processor for a few seconds. Keep it coming AMD.Lolimaster - Tuesday, April 27, 2010 - link
Watch tom's reviewhttp://www.tomshardware.com/reviews/amd-phenom-ii-...
More justice to the AMD cpu's. Just pass the synthetic intel compiler bugged benchmarks.

Actualy the results are what I expected and what was also explained in the review. Not stellar, but very good for the money spent ...I guess I'll buy one of the 4-cores.

Anand, why do you not try to push the chip on overclocking? Also, why not do an I7 overclocked vs Phenom X6 overclocked performance comparison? Overall, I feel that this review was pretty limited and unenthusiastic for such an exciting product.ymetushe - Tuesday, April 27, 2010 - link
Second this. I was really hoping you'd do some overclocked benchmarks, say at 4GHz, so that we could see clock for clock performance of 6 Thuban cores vs. 8 Bloomfield/Lynfield threads.JGabriel - Tuesday, April 27, 2010 - link
Check the x264 and Cinebench results. Clock for clock, at 2.8 Ghz, two hyper-threaded Lynnfield cores seems to match three Thuban cores - at least for rendering & encoding purposes..

I try to provide a look at what sort of headroom you can get out of the chip while feeding it as little voltage as possible. The idea is to keep power consumption at a minimum while increasing performance. I found that the jump from 3.8 to 3.9GHz required quite a bit of additional voltage, while just going to 3.8GHz was basically a non-issue - which to me is more impressive than trying to squeeze another 100 - 200MHz out of the chip.Take care,
Anand
