Sources among Intel’s partners said the company will unveil its new server chips introduced back in February on Monday, the 28th of June, 2004. The introduction will be notable because of the fact that Intel starts shipments of its first 64-bit IA32 chip. Previously the company only supplied 64-bit IA64 products.
The new Intel Xeon “Nocona” processors will be fairly different compared to the Xeon CPUs shipping now from numerous micro architectural points of view. The main difference is certainly support for 64-bit extension technology; however, there are numerous factors that will drive speed of Xeon products upwards. Firstly, Nocona’s L1 cache is two times larger compared to the current Xeon DP processors’ and equals to 16KB. Secondly, Nocona includes 16K uOps Trace Cache, a substantial improvement over current 12K uOps. Thirdly, 90nm DP products will make use of Prescott’s new, more efficient branch prediction mechanism. Fourthly, the fresh Xeon 1M microprocessors will feature SSE3 technology. Fifthly, the innovative Xeon chips will have 1MB of L2 cache compared to 512KB L2 cache on current offerings. Finally, the new Intel Xeon “Nocona” will boast with enhanced efficiency of the Hyper-Threading technology. Additionally, the new Xeon chips will have 800MHz Quad Pumped Bus, a boost over Intel’s present Xeon chips’ that feature 400MHz or 533MHz processor system bus.
In addition, Intel will release its much-anticipated Tumwater (E7525) core-logic for 2-way workstations bring PCI Express x16, dual-channel DDR2 SDRAM memory as well as some other capabilities for the workstation market segment. Server chipsets code-named Lindenhurst will be available in the third quarter.
World’s leading workstation makers – IBM, Dell, HP and some others are expected to release workstations powered by Intel’s Xeon DP chips with EM64T technology.
Officials from Intel did not comment on the story.

So does this mean Windows XP 64-bit is coming soon since Intel won't release the hardware if the software isn't there to support it?

I think the realities of life dictated that they not wait till the OS was in place to offer the chips. Classically the hardware always comes ahead of the software, otherwise why introduce SSE3?
Be interesting to see how it performs however, or if AMD64 will be out and out more efficient...

To bad there isn't lot’s of 64bit software, to see who’s faster at 64bit.
I was watching a document of Intel Willamette 42M transistors:
SSE2, HT, 256kb cache,...
Too bad Prescott isn't a dual core Willamette, less transistors (84M) and i bet better performance.

All the LGA 775 CPUs are crippled with only 36 address bits. And if you are going to cripple your 64-bit technology, at least include NX. I didn't see any mention of it.

Hmmm, so all these enhancements are noted, but what about the added pipelines. It has been shown time and time again that clock vs clock Northwood vs. Prescott, Northwood is faster 90% of the time.
The main benefit to the newer chips is the addition of 800Mhz FSB. I guess we'll have to wait and see how much it improves performance. They are still suck with a shared bus architecture for multi processor systems.

If it were going to perform well, you'd have seen specs by now...
We all have seen how the 925X turned out. Intel can't compete on the high end, and turning down/off the oc'ing is really just to keep people from finding out that even later (overclocked) they aren't going to get back on top again.
Turning off the overclocking was kind of trying to hide their dirty laundry.
