AMD's Quad FX: Technically Quad Core

Gaming Performance with Half Life 2: Episode One and Valve SMP Benchmarks
Intel continues to be at the top of the charts in gaming performance with Half Life 2: Episode One:
And once again, Quad FX doesn't do so well if all you're doing is running a single game; an Athlon 64 X2 setup is faster.
Our final two benchmarks are synthetic tests that Valve left us with to give us a preview of the impact of multi-core CPUs in future games. We've talked about both of these tests in our Valve Hardware Day 2006 article if you're interested in learning more about them and what they do.
Both tests favor Intel's Core 2 processors, but both show incredible scaling from two to four cores.

Could the reason be that 1GB per memory node is simply too little?On a configuration like this, you'll easily see one of the nodes with only 256MB or so left...
So, put in some more memory! At this point 32-bit XP will be limiting, even for 32-bit apps. (XP won't address more than 2^32 Bytes, some of this will be masked by PCI and PCIe devices, and additionally each process only has a 2GB address space for code&data unless you upgrade to 64-bit Windows) Also be aware that nVidia ForceWare 80.00 and newer lost PAE support. You'll experience crashes and non-working games if combined with a PAE aware 32-bit OS (such as Win2003). ForceWare 79.11 works fine though.
(BTW: MSFT added NUMA support in XP SP2)

Hi Ananand,sounds credible, because there is some extra cache snooping traffic going on, anyways, please keep us posted if there is a new BIOS version available, and if it would "do" something :)
Windows schweduler differences between XP and VISTA would be interesting, too.
So far there were only Win32 XP vs. Win Vista64 comparisions, not possible to draw a fair conclusion with that data.
Thanks a lot

One important question:Are those new FX-7x CPU identical or is there some differentiation employed ???
Kiijibari - Saturday, December 2, 2006 - link
identical to what ?If you meant Socket-F Opterons, then yes, they are identical, if the BIOS allows it, then normal Opterons should be able to run in 4x4 boards, too.
cheers

Thanks that info(if correct) pretty much clears the FUD.Griswold - Saturday, December 2, 2006 - link
How so? The 2P+ Opteron IMC wants buffered RAM, while these FX types do not. I dont think a simple BIOS hack can circumvent that.Kiijibari - Saturday, December 2, 2006 - link
*gasp*Du you really think AMD engineers, tests, validate, etc. a CPU for a niche market ??
There are maybe only a few thousand 4x4 CPUs, that are sold worldwide per month ... it would be economical ridiculous.
But if you dont know anything about business, maybe that will convince you:

All idiots talking about old CPUs here :D Fast forward 11 years, Ryzen will be out in a week's time.
