AMD's Phenom II X4 965 Black Edition

Power Consumption
Idle power consumption is a strong point of the Phenom II architecture, only the i7s manage to draw less power. Under load, the 965 draws the most power of anything on the chart - there's its 140W TDP hard at work.

amd's only hope to beat the i7s is the istambul core, if it brings istambul to the desktop market, I guess this future cpu can beat some high-end i7 processors, and after some revisions on the deneb core, amd will place it to ''fight'' the i5s leaving the athlon x4 playing against the i3s, but most denebs must be at 95W to be efficient against i5. of course this strategy depends if amd is economically capaple of putting a 300mm squared die in the desktop market...deneb is already too large to compete against the i7!Denithor - Friday, August 14, 2009 - link
You measured performance in video encoding and then power consumption under the same test. Why not take the obvious next step to calculate performance/watt and post those results?And I was quite disappointed to see that you posted only about half of each CPU list on each of those charts - a few chips overlap but many do not so we cannot even do the calculation for ourselves except in less than half the cases.

Two things : Intel's SSE extentions are used by everyone, and should be the difference in some of these tests.

The other disturbing thing is the FarCry benchmark, the writer:
FarCry 2 is another example of a title well optimized for Intel's architectures and thus we see that the 965BE can't even win against its Q9550 competition. Thankfully for AMD, I do not believe FarCry 2 is representative of the majority of titles on the market.
I believe this is an example of how SSE extentions deliver; but looking at the game benchmark data closer, we see that all cpu's are comparatively the same even the i7's vs Intel Core ll. Most, if not all vendors optimize in Intels favor

Intel's biggest (only?) advantage is hyperthreading; realize Windows 7 had to be optimized (how much more code?)for hyperthreading..how will Intel's i7's react in an openCL, CPUGPU environment (WARP) compared to Phenoms II's and an ATI graphics card, is it cost efficient(less code) and more efficient (faster) to go with CPUGPU over hyper..Will multicores do away with hyperthreading? These current comparisons on vista or XP do not necessary reflect comparisons on Windows 7 or DirectX 11. staytuned- Thursday, August 13, 2009 - link
I would also love my excel spreadsheets to have the advantage of CPUGPU...Photoshop too- Thursday, August 13, 2009 - link
oh yeah, Intels game plan to fight AMD's CPUGPU concept-a)license the SLI technology from Nvidia for Nehelam
b)get Microsoft to optimise Windows 7 for hyperthreading (sidebar-Intel pushes Windows 7 for corporate upgrades- can you say payoff))
innovative genius
but in reality they will probably make sure this great technological concept dies, thereby assuring comp's remain in the dark ages for another 10 years

You really had zero clue what you were talking about .... it is funny to come back in time and re-read all this AMD fanboy nonsense. Very entertaining, thank you for the horrendously great laugh.ash9 - Thursday, August 13, 2009 - link
"Now once you start throwing in background tasks and look at future titles being more threaded then the picture becomes a little more muddy"I dont understand where the writer is going with these conclusions. As CPUGPU or OpenCL begins to take hold, the old comparative model of simply looking at raw speed becomes obsolete, now, overall power can be reduced while concurrent events run parallel in multicores and GPU, thats is where AMD is heading. These comparisons with Vista may not be as eye opening as compared on Windows 7 or DirectX 11, this is where AMD planed to rock and roll from the start.
