Very intresting!

Your "upgrade" Phenom 9500 ~ (4U / 38.5) / (2U/27.0) ~ 1.4 faster than my Core 2 Duo E6550 @3.15 GHz!


But note that you run your C2D under Windows using the E@H client that still uses scalar FPU instructions, while the Phenom is running under Linux and is using a "power user app", which means faster SSE (vector) math instructions. If you were using that app as well under Linux, your C2D would be able to come much closer to the Phenom although the Phenom has twice as many cores.


Can we run this application under Windows in the not very distant future?

Thank you for attention!

I was wondering, too, if Windows is even being considered for such an "upgrade", or is the risk too high because so much of the work is being run on Windows machines and it is not worth the risk of changing from the very successful Windows 4.15 app?

Thanks! :)

Bernd wrote in this message about the top development issues on his agenda, most of the items are related directly or indirectly to increasing stability rather than performance, but OTOH the current Mac OS and Linux "power user" app got completed as well, so there is some hope for Windows users.

Does Phenom benefit from SSE as much as Intel CPUs? My Opteron 2218 doesn't show any notable speed difference between 4.20 and "power user" 4.21 and I've seen reports that Athlon-64 is in the same boat ...

In "theory" it really should, as the K10 generation of AMD CPUs includes improvements in the SSE vector unit that are similar to those for the Core 2 : 128 wide internal data paths, more parallelism in execution of SIMD instructions... but somehow it just doesn't seem to deliver ... I think it's not unfair to say that there's a general feeling of disappointment with the K10 performance so far, and the E@H app is no exception.

How come he was able to

How come he was able to install the AMD Phenom in Linux in the first place? Old motherboard?
I actually went to the post office and got my BE2300 with the Asus M2N-VM motherboard but all components listed in are "unknown" hency i am not able to get even the tiniest piece of a workunit through the non-existing NIC.
Tested under gentoo-sources 2.6.23-r3 kernel-version.
Any idea anyone?
Since then running in Windows XP Pro x64 eval, soon to be Windows Server 2008 RC0 Standard.

Both ARCH Linux and Fedora 8 installed with minor hassles. First on a BioStar TF560 A2+ (a "Kludge" MB- Bios fix to run Phenom, but had Bios problems with "Cool & Quit"- found workable Bios at Rebels Haven), and then on an ECS A770M-A.
The performance is not what I would like, but it does twice the work of a 3800+ X2 with the same power usage. I'm waiting for the new Steppings and then I will try again.
PS- The 9500 doesn't over-clock worth a flip. I could get the bus from 200 to 204 (anything higher would not post in either MB)- I didn't even bother to try and run it there, just set it to "stock" and went with it.

I could set up a Phenom 9600

I could set up a Phenom 9600 to crunch Einstein WUs.

CPU:2300MHz / NB,L3: 1000MHz / RAM: 800MHz
Power consumption with Einstein@Home: 128W

The inability to do an FSB overclock with phenom is fairly well known. Fortunately unlike Intel's Extreme Edition CPUs AMDs Black Editions provide unlocked multiupliers at a reasonable price and the phenom does overclock reasonably well by increasing the multiplier.

Well, the Q6600 and Xeon3210

Well, the Q6600 and Xeon3210 doesnt need unlocked multiplier to OC well, and Q6600 dont need overclock to outperform an overclocked Phenom, as Phenom Black Edition does not overclock that well, 3GHz is as rare as bicycledoors.
