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

3dsmax 9 - SPECapc 3dsmax CPU Rendering Test
Today's desktop processors are more than fast enough to do professional level 3D rendering at home. To look at performance under 3dsmax we ran the SPECapc 3dsmax 8 benchmark (only the CPU rendering tests) under 3dsmax 9 SP1. The results reported are the rendering composite scores:
The Phenom II 900 and 800 series are once again competitive with the equivalent Intel offerings. Since we're dealing with a well threaded workload, the Phenom II X3 720 manages to inch ahead of its Core 2 Duo competitors.
Cinebench R10
Created by the Cinema 4D folks we have Cinebench, a popular 3D rendering benchmark that gives us both single and multi-threaded 3D rendering results.
Taxing only a single core all you can rely on is frequency, hence the E7500 being at the top of the charts. But we are in the multi-core era, so let's look at the multi-threaded results:
AMD does very well in the multi-threaded Cinebench test thanks to its architectu, only the fastest Core 2s and of course Core i7 are able to outperform the Phenom II. The triple core 720 has a clear advantage over its dual core competitors here.
POV-Ray 3.73 beta 23 Ray Tracing Performance
POV-Ray is a popular, open-source raytracing application that also doubles as a great tool to measure CPU floating point performance.
I ran the SMP benchmark in beta 23 of POV-Ray 3.73. The numbers reported are the final score in pixels per second.
AMD continues to do quite well in POV-ray. The 900, 800 and 700 series are all competitive.
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 more cores the merrier; AMD does very well in our par2 test, especially down at the X3 720 level. Nothing can touch the 8-threads of madness that is Core i7 however, but today we're talking about much lower price points.

"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?
