There are some CPU WEI numbers here.http://episteme.arstechnica.com/eve/forums/a/tpc/f/99609816/m/961009454931/r

a part,
C2D E8400 @ 3.0 ghz Processor: 5.8 (Apparently other factors play
Processor: 5.7 so the CPU benchmark dependson more
Processor: 5.6 than the CPU.)
Core 2 Quad Q6600 (2.4GHz) Processor: 5.9
C2D E8400 @ 3.6 Processor: 5.9
*******
So 2x3.0 = 6 units, gives 5.8
2x3.6 = 7.2 units, gives 5.9
4x2.4 = 9.6 units, gives 5.9
Hard to say how AMD would compare. On integer, Q6600 beats AMD. On
floating point, then a 9850 or 9950 would be needed to match it.
So a Toliman won't be enough, as near as I can guess. You'd need
the top AMD processor, if you hope to hit 5.9. And it's not that
expensive.
According to my best guesstimate, a Toliman would need to be clocked at
2.8GHz to score 5.9 on WEI. This processor (8750) is one of the first
phenoms said to overclock well, some have reported 3GHz stable. I'm not
counting on it. I'll be happy to hit 2.6 or 2.7GHz stable, which should be
no problem with either motherboard, the DFI or the Foxconn. But then there
is the X factor. That is, a CPU that is capable of 5.9 can be held back by
other components. And, those "other components" can be held back by a slow
CPU, also. There are just way too many variables to predict what your WEI
score will be, until the system is actually built. But near as I can tell,
I will be one of the first builders to use really high quality components to
support a 8750, AND who cares to benchmark it with WEI. It's going to be an
interesting experiment to be sure. I'll be surprised, but not too
disappointed, if the CPU doesn't quite hit 5.9. In other words, if I aim
for 5.9 and hit 5.8 with the lowest score being the CPU, but the CPU is
STABLE and cool at 5.8 WEI, I'll be happy. And if that happens, I will have
confirmed that, building with AMD, the minimum requirement for 5.9 WEI is a
9850:
A 9850 at 2.5GHz will do 5.9 on WEI (not overclocked). But this is $35
extra, and draws more power from the power supply and voltage regulators.
This will also generate more heat that needs to be removed. All this is not
a big deal, but I see no reason for four cores (as opposed to JUST three
anyway) at any time that this system will be in use. Besides, if you know
in advance what your WEI score will be, what's the fun in that? Ha Ha
And a 9950 at 125W (now that there is such an animal) will be virtually
identical to a 9850, yet cost a little more.
Actually, a two core processor would probably do just fine, for now. But
I've always been partial to AMD, even with their recent troubles. And with
these triple-core processors being fast and relatively cheap, I see no
reason not to give it a shot. :)
I did consider a Q6600, but couldn't stomach paying 50 bucks more for a
processor clocked at 2.4GHz. And a Core 2 Duo is so ummmmm, yesterday. :)
I have nothing against Intel. I've built with them in the past, will
probably build with them in the future. But I want to go with AMD this time
around. I suspect that having three or four cores will help tremendously,
whenever the next OS (to replace Vista) is released. So I think a 8750 is a
wiser choice for future-proofing than a C2D anything. Not that I care to
future-proof this system, but if the price is low, it's a no-brainer to opt
for a more future-proof processor. And as I said before, a Q6600 just does
not look that appealing for an extra 50 bucks, and that is the least
expensive processor with more than two cores in the Intel lineup, near as I
can tell. -Dave
