That is awesome. I can't wait to buy an E8400 or a Q9450 and OC it hopefully over 4Ghz on air.

It will be quite an upgrade from an AMD XP-M 2500+.

Wow, I'm seriously tempted to buy this cpu.

Do you guys think I'll notice a big difference from an E2160 @ 3ghz to this? I.E. do you guys think my cpu is bottlenecking my games yet?

At what voltages did you get that OC?
I would like to buy one to but i would like to keep the Cpu many years to come so could you tell me the max oc at standard voltage?
Thanks

Wow, I'd probably go with something like this over a slower quad core.

I can definitely back up the 4 GHz on air bit, I've seen it done by multiple people, although whether you'd want to keep it there for everyday use, I'm not so sure.

Bu the bottom line is those Wolfdales are pretty freakin' impressive.

Dry ice can do it for you however a vCore of 1,86v is too high for my liking :shock:

Picked up one for a build this weekend and one for another forum member and they are both running 4.0GHz at 1.28v. I'm extremely impressed with the performance and the temps are extremely good. With a Thermalright Ultra Extreme and Scythe S-Flex (model F) fan load temps in Orthos/Prime 95 have yet to break 53c!! :prayer:
These things make great folders too...in Win SMP it's just a touch over 9min per percent which is solidly in quad core territory, the QX9770 at 3.8GHz is just 2min faster.

Man, I want a 4Ghz cpu.

Launch the rest of the 45nm quads already intel!

what about vs the e6600 oc'd to 3.4? is that better or worse? or phenon at 2.6?. I've looked up some benches but, nothing really looks to trustworthy. Its all biased

Nice summary via hardwareanalysis forums
Ok here are some benchmarks on the new 45nm Wolfdale E8400.

Here is how they compared them to benchmark the architecture clock for clock:

all three processor where set to dual core @ 2.4ghz

stock Wolfdale E8400 = 3ghz 1333fsb (333fsb x 9) ---> down clocked to 2.4ghz 1066fsb (266fsb x 9)

stock C2D E6600 = 2.4ghz 1066fsb (266fsb x 9)

stock Phenom 9700 = 2.4ghz quad core ---> two cores disabled




benchmark review = http://www.pcgameshardware.de/?article_id=622892 (it is in German)

benchmark graphs of results = http://www.pcgameshardware.de/?menu=bro ... _id=741790


so from the graphs... it looks like:

Wolfdale = 10~15% faster than C2D @ same clock speed
Wolfdale = 16~26% faster than Phenom @ same clock speed
C2D = 9~15% faster than Phenom @ same clock speed
You can't really say which would win out with a 3.4Ghz conroe vs a 3Ghz wolfdale, as the wolfdale can be overclocked to match the conroe speeds with ease, negating the mhz difference and taking it back to architectural improvements as shown above.

awesome thanks Dan
The phenom was tested as a dual core? So what about at 4 cores? Anyone know the difference in a program that uses all 4? And so far seems the wolfdale is winning. But, the phenom seems pretty decent.

So that 5ghz overclock was reached with dry ice cooling? That's interesting...

Anyone have any links to interesting articles about exotic high-end cooling solutions like that? I wouldn't mind doing a bit of reading tonight. :)

This looks like a really nice cpu, relatively cheap also.
Might be the new "gold" :)

I'll seriously think of throwing out my Q6600 for this

No reason to go quad core with cpus like this.
