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.

"We're in the midst of a price war folks, and at a time when the global economy is looking a little shaky this actually works very well for us. Let's recap what's happened."That works very well for us until AMD, despite having a good product portfolio (this includes video cards), goes belly up thanks to this worldwide recession (a little shaky? Where have you been the last couple of months!?).And then what? Back to moon prices courtesy of Intel?
I hope not, but fear the worst. :(

Why does the Ph II 940 system use only 4W more than the 810 at load? This is not consistent with TDPs (125W vs 95W). The HEXUS.net review found a 23W difference under load. Is something wrong here?Axloth - Monday, February 9, 2009 - link
I'd love to see detailed test of impact of cache size per core, because test results in this review are really weird. Something like x4 910 vs x4 810 vs x3 710. Pretty please with sugar on top...ET - Monday, February 9, 2009 - link
Needs more comprehensive testing, period. The results look really strange sometimes. Not only did the 810 sometimes outperformed the 910 significantly, but the 710 consistently beat the 910 in the gaming tests.(So far -- and I haven't read other reviews -- the 710 is looking like a good candidate to replace my aging X2 3800+.)

From the rumors ive seen in the web, this will be a pretty cheap cpu.Myt little brother is crying for My 4800 X2 (he always get free upgrades) with 4Gb DDR2.
Just one question, With a Stock VID 1.325 to 1.55 isn't that a little bit aggressive (even with good air cooling), for everyday operation ? I was hoping for a OC up to 3.6Ghz in decent voltage. 3.8Ghz Would be very good, but the voltage seems somewhat too large for day-to-day operation.
Thanks for reading, and replying if you have the time, of course.

On our samples, starting around 3.5GHz you really had to ramp the Core VID. 3.6 required about 1.45V in the BIOS, with droop it was around 1.4375V real on this board. If the retail chips follow the 940, then I would say around 1.425V should be realistic for 3.6GHz on the right board. 1.55V is not outside of AMD's spec and is the limit they have found for air cooling. It is about the same limit we have noticed also for the most part, but these chips are designed to take a lot voltage if you keep them properly cooled.RadnorHarkonnen - Monday, February 16, 2009 - link
I'm already checking prices and availability for this hardware. I'll check the speed bump and the temp bump between 3.5 and 3.6. Thanks for the info Gary.duploxxx - Monday, February 9, 2009 - link
most run 3.4 ghz already on stock vcore@review, you state that there is no performance difference between ddr2-ddr3 but you didn't show anything? Anyhow official statement from AMD is that the ddr3 part bios is not fully ready yet, so I hope you will do a full review later.

"@review, you state that there is no performance difference between ddr2-ddr3 but you didn't show anything? Anyhow official statement from AMD is that the ddr3 part bios is not fully ready yet, so I hope you will do a full review later."AMD told us a couple of weeks ago to concentrate on performance with the AM2+ boards since the AM3 BIOS releases were immature. I received several BIOS releases last week for our AM3 boards and felt safe enough to display numbers with them in the OC section today.
We are still testing and will have comparisons up in the near future. That said, we still have a list of requests back to the motherboard companies to fix. For the most part now, the AM3 boards are usable and clock well. I figure another BIOS spin or two and they should be good to go.
Also, in a best case scenario, AMD had performance improvements of 5% at best in memory bandwidth limited benchmarks with DDR3. Things might change with the 945 hits in a couple of months, but on these processors, there really are not any differences between DDR2 and DDR3 at this point.

Power consumption and framerates at the max stable overclock?
