View Full Version : Early Intel Nehalem Performance Projections Leaked

A leaked PDF from Sun Microsystems' website (which has now been removed) suggests that Intel could have something quite impressive up its sleeve with its upcoming Nehalem processor. The processor was already rumoured to feature three channels of DDR3 memory per core compared to two channels of DDR2 per core on AMD’s Barcelona and upcoming Shanghai CPUs, and it seems that could give the Nehalem quite a performance boost. Extrapolated figures from ZDNet based on data in the slide are shown in the graph below, and as you can see, the Nehalem on average scores twice as highly as a 2.3GHz Barcelona and almost 40% better than a 2.8GHz Shanghai in SPEC CPU tests. As always with benchmarks on unreleased hardware it’s important to remember that the data may not be accurate and synthetic benchmarks don’t always reflect real-world performance, but if these are at all reliable then Intel’s next generation of processors could be a huge leap forward.

Thanks to [I.R.A]_FBi (http://www.techpowerup.com/forums/member.php?u=39344) for sending this story in. I have attached the PDF from Sun with this post - make sure to scan for viruses just in case because I had to upload it as a compressed file, although I'm pretty sure my system's clean.

That looks like a huge performance jump, folding@home should be pleased with this new information ;)

It will be almost early 2010 by when we could see a humanely-priced desktop implementation of this architecture. I'll wait. This humble Kentsfield will cruise me to 2010 at a blink.

A bit late for this to go up on the news page.

Im most impressed by how well the AMD Shangai 2.8ghz QC did compared to this, 2 points less I think? Impressive. Also impressive is the scores over current intel cpus.

Are you sure about that info? Could be... but I thought skulltrail on FB DIMM was able to go quad-channel. Seems odd that Nahelem wouldnt keep quad channel or go better.

Just for the know, Nehalem is of a totally new/different CPU socket from the LGA 771/775.

Nehalem: 163FP/176INT
Shanghai: 121FP/123INT

Nehalem wins by 30-40%. What "2 points or less" are you talking about? Are you sure about that info? Could be... but I thought skulltrail on FB DIMM was able to go quad-channel. Seems odd that Nahelem wouldnt keep quad channel or go better.Only MP Nehalem will use quadchannel FB-DIMMs, DP and lower are dual/trichannel DDR3.

Nehalem Desktop gets dual and trichannel
server version gets tri and quadchannel not sure about quadchannel its more for FB dimm

-edite-
nvm :P
Nehalem for the win :)
and nehalem comes in 3 socket types
