Intel Pentium 4

Last guide, we were impressed that Intel managed to release their “ Prescott 2M” Pentium 4 [RTPE: “Pentium 4” 2MB] processors ahead of schedule. Intel CPU pricing is fairly stringently controlled, and so after the initial fluctuations while shipments were coming in, prices have pretty much leveled out at where they will remain until the next pre-determined price cuts. A new Prescott 2M, clocking at 3.8GHz, is also in Intel’s near future. We are under NDA for those sorts of topics, but in completely unrelated news, May 26 th looks like it will be a wonderful day for a picnic.


For those of us not ready to move up to the larger cached chips, Intel is still breathing life into the 5xx series with some new SKU announcements. Several months ago, all Pentium 4 5xx ( Prescott) processors received a revision bump as Intel enabled XD protection on their chips. These new processors received the “J” suffix although most merchants didn’t really differentiate the “J” processors from their non-XD predecessors. Sometime this month, Intel will start shipping the XD processor successors, which end in a “1”. These new processors are identical to the “J” revisions, but now also have EM64T. For those of you following at home, you may recall that EM64T instructions are already on the Prescott core, and enabling the extensions doesn’t require any new fabrication techniques on Intel’s behalf. Expect the “5x1” processors to replace the “5x0” processors quickly.


The 3.4GHz Pentium 4 550s are the most popular Pentium on the market right now, but prices aren’t moving:


Intel Pentium 4 (775) 550 800FSB 1MB

To hint a little bit at the upcoming Intel schedule, sometime in Q4 this year, the higher echelon Prescott 2M processors will also receive a similar revision bump. All of the 6xx chips already have EM64T, but Intel’s virtualization instructions – VT – are not present yet. Processors with VT will end in a “2” in their product name.

The dual core “ Smithfield” Pentium D processors are starting to show up for preorder on several vendors. Pricing seems extremely competitive, but we will have more details once the chips are actually available.

    i don't know... after seeing the next gen consoles i care a lot less about new x86 procs. even in their early days the next gen consoles should cost less than the x2.

    AMD Athlon 64 (939) 3700+ 1MB San Diego is $329 not $299
    that suprised me...

    where are the X2's?
  • Rand - Monday, May 23, 2005 - link

    Any reason why you don't list any of the 533MHz FSB Pentium M's?

    Can't wait to see if AMD includes 64-bit on Sempron processors now.

    Kristopher,
    May be a slight error or 2 in the AMD SKU overview.
    "Hammer" is not the name of *any* AMD stepping. It's the very general code name for the K8 architecture, encompassing, well, everything.
    You meant "ClawHammer". And it's not true that all ClawHammers are C0; there are some CG's. Consider the socket 754 3700+, and some of the mobile chips. Unless the ones that I think are CG are actually the SledgeHammers.
    Speaking of SledgeHammers: it's the FX-53/4000+ 130nm and FX-55/130nm, which are said to have ripping memory controllers compared to like-week'd NewCastles but are otherwise similar to CG ClawHammers.

    And were are the opterons?

    I see no mention of the Pentium M Sonoma Plaform why is that? It woudl be nice to include this is your review for next time.

    The best buy is socket 939 3700+. Its a San Diego core, it has 1MB cache, new SSE3 instructions, its memory controller is revised and its under US$ 300,00. Not quite a bargain, but still an incredible price/performance ratio.

    That would be my pick, if a powerful system was needed today.
