Intel Begins Shipping 64-bit Prescotts

Posted by CowboyNeal on from the unheralded-releases dept.

Rucas writes "With a minimum of fanfare, Intel has begun shipping a version of the Pentium 4 with 64-bit instruction set extensions. The news came to light not via an Intel press release, but rather through the spec sheet for a new server from IBM. In the midst of the new IBM eServer xSeries servers based on the recently released 64-bit Xeon is a blade server powered by the 64-bit Prescott. This marks the first product appearance of the new CPU."

  2. Xeon-Nocona no faster on 64-bit code? by vincecate · · Score: 5, Informative
    There are benchmarks from anadtech.com and xbitlabs.com that show AMD64 chips have higher performance on 64-bit code. Since there are more registers in 64-bit mode, it seems very reasonable for it to run 64-bit code faster. However, both theinquirer.net and infoworld.com claim that the 64-bit performance of Xeon-Nocona is no higher than its 32-bit performance. At first this seems unreasonable, since it will also have the additional registers that helped AMD. However, some of the 64-bit instructions can be longer, so relying on a big cache may not work as well and high memory bandwidth may be more important. So it could well be that AMD's chips are better suited for 64-bit code.

    Though Xeon-Nocona has been available for more than a month it seems there there are no substantial reports on 64-bit performance of Nocona. Is there anyone here who can report anything about the 64-bit performance of Nocona?

  3. Dell is shipping 64-bit Pentium 4 workstations. by MojoStan · · Score: 5, Informative
    This slashdot story (and the Ars story it ripped off) seem to say that only servers are getting the new 64-bit Pentium 4 Prescotts now. That is false. In case you missed it, Dell is now shipping the Dell Precision 370 workstation with 64-bit Pentium 4 (EM64T) at 3.2GHz, 3.4GHz, and 3.6GHz.

    Also, Anandtech just posted a new roadmap with some info on upcoming 64-bit Pentium 4 CPU/chipsets for the desktop. The Intel 925XE chipset (with 1066MHz FSB) will ship in October along with 64-bit Pentium 4 "F" processors. "F" supposedly means it's a 64-bit Prescott.

    Please do not post links to thefreedictionary.com - they are a dodgy site which repackages Wikipedia content, with ads, for profit, whilst stretching the GFDL as far as they possibly can.

    Look at that link you posted - you'll see a credit to Wikipedia at the bottom. Now disable javascript in your browser and refresh - ooh, the credit is gone! They insert it in with javascript rather than putting it in the body of the page to ensure that Google doesn't pick it up. Why? Because a link to Wikipedia's article would help lift Wikipedia's pagerank above that of thefreedictionary.com.

    Just say no, and if you want to read about PAE, read the original Wikipedia article.
