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.

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.
