We desperately need memory benchmarks. :)
Run stream , it's a tiny program which should run no matter what.Used for testing the memory system of computers ranging from desktops to servers with thousands of CPUs.
http://www.cs.virginia.edu/stream/FT...32/wstream.exe
You'll need to open the command console ( remember where you saved it ) and type wstream <core frequency , 2933 this case > < iterations , try with 1 , 4 and 8 >.
Something like this c:\...desktop\wstream 2933 4
*I've noticed you're running single channel mode.
Those Wprime benchs are really impresive, compare to a QX9650 below:
So your 2.93GHz (with dual channel?), beat my result at 4.2GHz with Dual Channel (by a fair margin)

this Nehalem is going to be a monster in multi-threaded apps even if it only does 3.6GHz on air.
Thanks for all the benchmarks JC. I was going to buil d a Q67000 or Q9450 system for video editing, but now I will wait for Nehalem. As others have noted, this looks like it will be a great multi-thread chip. Just what I am looking for to run Sony Movie Studio (which can generate upto 4 threads :up: )
Yup... just about 50%:

When I did my back of the envelop calculation, I used the 32M numbers... so here is what I get...
For Nehalem @ 2.93G
32M = 9.218 Secs
For Yorkie @ 2.93G
32M = 13.859
This translates to a increase in speed of 50.3% (these are time to complete so you need to take [(1/slower)-(1/faster)]/(1/slower) to calculate the actual rate, or you could convert into digitis per second and then it calculates out like FPS in game).
For Nehalem @ 2.93 G
1024M = 288.937
For Yorkie @ 2.93 G
1024M = 439.39
This translates to about 52% speed improvement.
This is estimated because I am using 1.58 Wprime, JC is using 1.55 Wprime.

wow, this is dropping some amazing numbers!!!! too bad we have to wait till q1 09 for retail :(
Thanks for the tests JC, we all appreciate it :up:
Very impressive Wprime speeds..
Would it be possible to change the thread count in ADV settings to 1 Thread.. Then we can really see how much SMT is helping the score?
:confused:
I'm not quite grasping your point... are you trying to say that while we currently don't know what the max Ghz Intel will release the new Nehalem @, it probably can't be faster than the current 3.2Ghz already known?
Knowing Intel always takes a conservative stance, which coincidentally has been proven by the EXTREMELY ingenious people here and elsewhere by overclocking them. Somehow, since nobody has officially posted Ghz in excess of 3.2gig, it somehow impossible or wrong to discuss them?

Actually I can. I just picked up a refurb Dell Optiplex 755 with a E8500 for just over $600. I tried to build something similar at Newegg, but even using the cheapest components for everything the lowest total was >$700. Plus it comes with a three year on-site (in this case, meaning at home) warranty. This will easily last me until next year until the price/supply for Nehalem has stabilized. After that, I will pass it on to my wife.
From another thread I am wondering: Is it confirmed that there will be <600$ Nehalems in Q4 2008?
