The point of the E5620 is to get a 32 nm LGA1366 chip for less than the i7 970 sells for. The only other 32 nm Xeon that sells for less than $870 is the Xeon E5630, which is merely 133 MHz faster than the E5620 but costs a couple hundred bucks more. All of the rest of the 32 nm Xeons are very expensive and more expensive than the i7 970 and i7 980X.
[citation][nom]elbert[/nom]Pretty good article. I wonder how a AMD Opteron 6128 Magny-Cours would stack up? Could you try OCing the 6128? Its only $275 on newegg.http://www.newegg.com/Product/Prod [...] 6819105266I know the motherboard tho is going to be costly but the Rampage III Formula isn't cheap either. If ASUS would add some OCing options to the ASUS KGPE-D16 would put a smile on my face. The ASUS KGPE-D16 would be a nice SLI motherboard for this test because its an X16 PCIE. I think it would be easier to get ASUS to fix OCing with this mobo than get Intel to make an enthusiast xeon.http://www.newegg.com/Product/Prod [...] 6813131643[/citation]
I have the setup you describe there with two Opteron 6128s sitting on an ASUS KGPE-D16. Note that I run Linux and some programs they run won't run on WINE. Here's roughly how it would stack up with these units being tested:
- 3DMark Vantage: won't run on my system. I'm predicting it will come in under the stock Xeon E5620 since the stock E5620 is quite a bit behind the 4 GHz units, and the 6-core i7 970 is barely faster than the other quad-core units at 4 GHz.
- Sandra Arithmetic & Multimedia: should beat any one of those there due to having 16 real cores.
- Sandra Memory Bandwidth: eight channels of DDR3-1333 is more than twice as fast as their systems. The only question is to whether or not Sandra likes NUMA or not. If it does, then two Opteron 6128s would be much, much faster. If not, then it would be much lower. I'm downloading it right now and will update when I get to run it and tell you for certain.
- COD2: lower score than the E5620 since this is a clock-speed-limited benchmark that does not scale beyond four cores.
- Metro 2033: would probably be similar to the other units since this is not a CPU-limited benchmark.
- DiRT2: would be slightly lower than the stock E5620 since we see no scaling advantage with the i7 970 and a small decrease in framerates with the stock E5620 versus the other chips.
- Just Cause: not a CPU-bound game, just like Metro 2033
- iTunes 10: this is a single-threaded benchmark and the Opteron 6128s would be considerably slower than the stock E5620.
- Handbrake: should beat any of the chips there since this is well-threaded. I can't directly compare to their test since I don't have their same 1 GB VOB file to work on.
- DivX: should be the same story as Handbrake.
- XviD: not a very well-threaded program, and any of the chips there will beat two Opteron 6128s. XviD on Linux is poorly-threaded too.
- MainConcept: same as Handbrake and DivX, with the two 6128s likely being much faster than the Xeons and Core i7s.
- Photoshop: unknown. Photoshop loves Intel CPUs and is moderately-threaded, so I couldn't tell you if it would beat an i7 970.
- 3dsMax: the Linux version of this app scales very well, like the Windows version tested here appears to. The 6128s should beat the chips here handily.
- AVG: AVG isn't that well threaded beyond four cores, so the 6128s would not do all that stellar in this application.
- WinRAR: same as AVG, it's not a very well threaded program.
- 7-zip: is very threaded and two 6128s would be faster than any of the chips here.
- Temperatures above ambient: impossible to directly compare, but my 6128s run about 35 C over ambient (52-57 C) full-load using Dynatron A6s heatsinks with roughly 2000 rpm on the fans. The Dynatron A6s are far smaller than the units used to cool the LGA1366 chips.
- Power consumption: my system is obviously set up differently from theirs, but the CPU idle/load power consumption figures in my box are roughly in line with the 4 GHz chips and higher than the stock Xeon E5620. That is because I have two CPUs in the machine instead of just one like they do. A single Opteron 6128 has an idle power draw within a few watts of a single Xeon E5620 but consumes 20-30 W or so more power at full load.
