AMD's Fall Refresh: New Phenom II and Athlon II CPUs Balance Price and Performance

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.
Video encoding performance is a definite strength of the Phenom II X6. You get comparable performance to the more expensive Core i7 860. And without Hyper Threading, the Core i5s are unable to distance themselves from the Phenom II X4 970.
Again the Athlon II X4 645 and X3 450 dominate their respective competitors.
PAR2 Multithreaded Archive Recovery Performance
Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive
Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.
The direct comparisons we've been pointing out this entire match continue to hold as we look at different applications. The Phenom II X6 1075T performs as it should, while the Phenom II X4 970 falls short of the i5 750. The triple and quad-core Athlon IIs couldn't be better.
7-Zip Benchmark Performance
Included in 7-zip is a pure algorithm test that completely removes IO from the equation. This test scales with core count and as a result we get a good theoretical picture of how these chips perform. Note that the actual 7-zip compression/decompression process is limited to 2 threads so there's no real world advantage to having more cores.

OMG YOURRRR SO INSITEFULLL!!!11111Learn to spell, moron.

I just bought the 95W version of the 1055T and it took a few months for it to be available. I put it in my ECS A780GM-A Black Edition Motherboard and it works for awhile then the screen goes blank.Going to have to get a new motherboard. So much for backward compatibility with AM2+ socket.

I have seen a few desktops form OEMs featuring an AMD Phenom II X6 1035T.Is this an OEM only CPU ? Could you include it in your performance charts? Thanks

The 970BE looks interesting especially if it has headroom for more OC.coronaJet - Monday, October 4, 2010 - link
I think its astonishing, that the new Athlons X2 and X3 have lower power consumption than the old ones, even if they work at a higher frequency.How is that possible? Is that a new stepping or better voltage magagement ?

Looking at these charts. The Core i5 750 consistently beats the X4 970 and they're priced to compete against each other. Not only does Intel win more, but they win in all the areas that really matter to me; not to mention the power consumption advantage.Secondly, where AMD actually does very well, encoding video, that advantage is negated by the fact that regardless of how good the CPU is a encoding and rendering video doing those things on the CPU is almost entirely obsolete. I know I do all that stuff using my Nvidia GPU and it's exponentially faster.
In other words, AMD can't win anywhere at a similar price compared to intel. The ONLY reason I can see buying an AMD CPU and that price point right now is if the CPU is all your changing and you already have an AMD Motherboard. Unfortunetly for AMD if you're building a whole new system Intel is the way to go and every price point with decent profit margins.

Ivy Bridge is meant to be still on track for 2H 2011. This just seems crazy. Intel are not going to release a whole new generation in Sandy Bridge and then replace it within 6 months!??I guess they might just release a few 22nm parts like they did with 32nm but even that seems so unlikely right now. I mean we won't even have high-end Sand Bridge parts out yet and we will have the replacement for Sand Bridge at our door step!
Anyone know what is really going on?

I am quite confused as to WHY Athlon II X3-450 with higher speed is actually cooler and more efficient than X3-440? Also, the same between X4-645 and X4-635?!I thought they're all the same core, no?
If these are more efficient, are they ideal for HTPC stored in a cabinet? using Antec Fusion Case?
