The Phenom II X4 810 & X3 720: AMD Gets DDR3 But Doesn't Need It

Blender 2.48a
Blender is an open source 3D modeling application. Our benchmark here simply times how long it takes to render a character that comes with the application.
While AMD is competitive in many applications, some do favor Intel's architectures; Blender is one of them. Only the Phenom II 700 series is competitive thanks to its triple-core advantage.
Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
AMD is very competitive here, outperforming all of the equivalently priced Intel CPUs. The clock speed and cache advantage of the Phenom II X3 720 is enough to even outpace the Core 2 Quad Q8200.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
The performance breakdown is more of what we've been seeing here tonight.
WinRAR - Archive Creation
Our WinRAR test simply takes 300MB of files and compresses them into a single RAR archive using the application's default settings. We're not doing anything exotic here, just looking at the impact of CPU performance on creating an archive:
The entire Phenom II lineup ends up performing very similarly, largely because there are IO limitations at work here despite our use of an SSD. Cache size matters as Intel's smaller cache quad-core chips don't do nearly as well as the 12MB behemoths.

In the Sysmark benchmark results, you have the following comment:Against to its Intel competition, the Phenom II X3 720 falls short of the Core 2 Duo E7500 and the E8400. The X4 810 also falls short of one of its intended targets: the Q8200.
While the X3 720 does fall to the E7500 (didnt bother comparing against E8400), the second line about the X4 810 losing out to the Q8200 is totally unfounded. The Sysmark results have the AMD chip losing in only 1 test set and the AMD wimming in the other 4 or 5.
I would probably buy the Intel anyway in today's market, but you should at least keep your review as honest and accurate as possible.

I've seen some scores with the X4 810 at ~3.7GHz, but not with a 2.7GHz NB clock.That would be nice to see some benchmarks at this clock speeds to know what is the boost in performance with a so higher nb clock speed.
Including a simillar clocked Core2Duo would be very nice too.
ps: yeah, my english is not so great, so sorry if there is some gramatical erros ;D

I'm really surprised that no one there put any thought into testing the difference between the memory controller and L3 cache running at 2.0 GHz instead of 1.8 GHz.I mean, you have a BE edition, with the 940, so what would have prevented you from running at at, say 2.6 GHz, like the 920, putting them on the same platform, and then benching them so we could see the difference the "uncore" speed makes.
It's really an important consideration, because obviously AMD will be releasing Phenom II's at 2.8 and 3.0 GHz, with 2.0 GHz uncore speeds, on AM3, and it helps people make a decision whether to wait or not. With AM2+ is shackled with DDR2 (I don't buy that there's no difference between DDR2 and DDR3, especially when other websites have identified them to be roughly 2%), the degenerate speed of the uncore could exacerbate this issue.
My other question is, does the uncore on the 910, et al, still run at 2.0 GHz when running in the AM2, and AM2+ platforms? I don't see why it would, but anything is possible.
I think two sets of benchmarks would be interesting. An underclocked 940 (to 2.6 GHz) versus a 910 processor. One on an AM2+ (yes, it's obsolete, but people will still buy it for a while) with the exact same memory. This assumes, of course, the uncore runs at 2 GHz for the 910 on this platform. The other is the 940 in its obsolete platform running at 2.6 GHz, against the 910 running on the modern AM3 platform, with high performance memory. If you really want to be thorough, you can run the 910 on both the AM3 and AM2+, each with the best memory available for it. I think these would all be helpful.

Any word if there will be a Phenom II Black Edition in the near future?WillR - Monday, February 9, 2009 - link
Do you mean another Phenom II Black Edition? Is the 940 not good enough for you?jchan2 - Monday, February 9, 2009 - link
Why not? Imagine the ghz you can gain if there was one. AMD did it before, why not now?jchan2 - Monday, February 9, 2009 - link
Nvm, didn't realize the 940 was already BEWillR - Tuesday, February 10, 2009 - link
Yep. And it makes sense imo for only the highest clocked quad core and the highest clocked tri core to be Black Editions rather than also having an 8xx BE. I've heard they should have a 990 BE out Q3 or Q4 this year.strikeback03 - Monday, February 9, 2009 - link
Such as the 720 Black Edition tested here?jchan2 - Monday, February 9, 2009 - link
Yeah, besides the 720 such as the 800 or 900 series.
