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.

Such as power consumption/heat charts for the dual core chips.(I mean, come on, these chips still hang with the quads in many cases, I want to see how much better they are from a power consumption standpoint - is it worth the upgrade to quad if you've got a speedy dual?).
To me it looks like the AMD chips give a lot better scaling when increasing the core count (X3 720 -> X4 920) than the Intel chips (e8400 -> Q9650). In most of the multi-threaded apps the AMD processors saw >95% increase (of the theoretical 33.3% possible) versus Intel with about 70-80% (of the theoretical 100%) on average. I wonder if this has to do with the fact the AMD chips are monolithic in design (more efficient interface among cores).

The image of the "socket AM3" is actually of the AM2... it still has 940 pin sockets, not 938.JimmiG - Monday, February 9, 2009 - link
You need to change the "compatibility matrix" to reflect that an AM3 CPU will "maybe" work with an AM2+ mobo. Second-rate manufacturers like Asus will not release the needed BIOS updates for some of their older boards like the 790FX/SB600-based Asus M3A32-MVP Deluxe. If you have a SB7xx-based board and it's not made by Asus or another second-rate mobo manufacturer, the matrix is probably accurate.fishbits - Monday, February 9, 2009 - link
"We really have to applaud both companies here. Intel for responding so quickly and effectively; the 40% price drop on the Q9650 just made sense and now you can have a chip with 12MB of L2 cache for under $300 thanks to the Q9550."You're applauding Intel over this? To me, looks like they were screwing over customers with a gigantic artificial price premium. If it weren't for stepped-up competition from AMD, the price would have remained in the stratosphere. Intel is entitled to price however it wants, but I'm not going to applaud them for lowering prices only because another company exposed their gargantuan profit margin.
Juat a tiny taste of what would be to come if only Intel were left standing. If fanbois who wish AMD harm ever got their wish, there'd be no competitive pressure on CPU prices, and we see what Intel does in that position. We really need two healthy CPU makers in business.

You know something's fishy, when a supposed article about a new AMD CPU starts with one full page of how Intel is the greatest evar... (and how much dropped their prices, which shall suggest to your mind that they are more interesting while they in fact go from Gargantuan to "normal" pricing for their products...)Maroon - Monday, February 9, 2009 - link
^agree^Why in the hell would you "applaud" Intel for price gouging? I know it's partly AMD's fault by not having truly competitive cpus for the last 2 years, but I'm not gonna give Intel props because they had to reduce prices to remain competitive in those price segments.

AMD Phenom II X3 710 is gonna be priced at around 125-135 i imagine, maybe even less, and for that price im sorry its a clear pick for those on a budget!! Its got 7.5mb cache, 3 cores, and will overclock to 3.6ghz if the 720 is any indication. Such sweetness. Any eta on em yet?BLaber - Monday, February 9, 2009 - link
As far as I have read on some other sites AMD sent an email along with the test samples to reviewers to test the cpus on AM2+ mobo for time being bcz AM3 mobo bios are having some performance issues.Nightstalker - Monday, February 9, 2009 - link
I don't understand the conclusion that there is no benefit to DDR3, when these CPU's were tested with DDR2. How about including results on these CPU's with both types of memory so we can see how they perform?Gary Key - Monday, February 9, 2009 - link
We will have additional DDR3/DDR2 results this week, we had AM3 BIOS releases coming until Friday night, the last one actually worked although it broke AOD and TurboV compatibility on the ASUS boards. We still cannot get DDR3-1866/2000 working. Of course, DDR3-1333 is the highest official support offered but we figure if it is in the BIOS then it should work.
