Just recently we brought you a quick guide to AMD's 2004 CPU roadmap, citing that Intel's was already known and easier to understand in the first place thus necessitating the guide to AMD's roadmap.

Since then, however, we have received countless requests for a similar guide to Intel's forthcoming CPUs so we went to task on preparing a similar article for Intel's roadmaps. After flipping through pages of the latest Intel roadmaps, we realized that the Intel roadmaps aren't as straightforward as we once thought.

Unlike the AMD Roadmap article, here we're focusing on CPUs and chipsets, and what better way to start out than with a quick look at information we already know.

The Socket-478 Pentium 4 roadmap has already been published here and on other sites like The Inquirer, below is just a summary of what is already public knowledge:

What's important to note here is that 3.4GHz is the end of the line for the Socket-478 Pentium 4s; we've left the Extreme Edition chips off of this roadmap but you should be able to see where they fit into the picture.

It's also interesting to note that Intel will offer 533MHz FSB versions of the Prescott based Pentium 4; these chips will not have Hyper-Threading support.

Although the Pentium 4's days are limited on Socket-478, the Prescott-derived Celerons will continue to live on the platform:

Like AMD's multiple Socket approach, Intel will use the Socket 775 for high end (and eventually mainstream) CPUs, but keep Socket 478 around for Celeron and low end chips.

The Northwood Celerons are getting beat up pretty badly by sub $80 Bartons and even puny Durons but by adopting the Prescott core on the Celeron early, Intel might be able to pull ahead of AMD in price/performance for the entry level systems. The increased FSB frequency will help performance, as will the larger L2 cache but it will take a lot to catch up to AMD's performance in the value sector.

    #9, if you read the article it says that there WILL be a 533 MHz FSB Prescott and several other sites like Xbit have been saying for weeks that there will be a 2.8 GHz Prescott with 533 MHz FSB but with no HT support. In any case, the authors have fixed the table and it now shows a Prescott 2.8 GHz with 533 MHz FSB.

    I'm sitting pretty with my Athlon64 3200+. While there will likely be faster CPUs from both AMD and Intel this year, I don't really see a reason to upgrade from that chip for quite a while.

    To bad i've already decided on getting a Athlon 64 939 pin setup this summer. Sorry Intel, better luck next time.

    I believe that they were talking in regards to the "C" model of the P4 which use the 800mhz FSB, not 533mhz which the've stop producing last I heard.

    Could we have a updated roadmap for Xeons.

    I know were never happy are we.

    Shouldn't one of the Pentium 4 2.8GHz processors in the first table be listed with a 533 MHz FSB? Right now all are listed with an 800 MHz FSB. Reply

    #5: Yeah, I agree. $200 for a 2.8 says #1. Well $200 will get you an A64 3000+ that you can oc and upgrade (for a little while). Not only that, it totally dominates the p4 in everything except the encoding department, in which case it's pretty much even. Reply

    #1: Or, for less money, you can pick up an Athlon64. Once socket 939 comes out, thats the direction that seems most obvious to me. Should have a long upgrade path, and at least its a CPU designed for the future(64bit). Kinda sick of investing in 1985 technology on steroids... Reply

    Price/performance of the new Celerons will be interesting to see. I think the 256K of cache is still going to hurt it, but it might actually be able to pass up the Duron chips now. (I doubt it will be able to match the Athlon XP chips, though.) One thing to definitely look forward to is the likely HIGH overclockability of the 90 nm low-end Celerons. I wouldn't be surprised to see people take the 2.53 and 2.8 up to "FSB666" - which would clock them at 3.17 and 3.5 GHz - or maybe even higher. If they only cost around $100, we could be looking at a return to the "glory days" of the Celery! :)

    As for the Socket 478 ending at 3.4 GHz, I'm not too surprised. Or disappointed. Getting a good P4 right now is a viable option - you can pick up the 2.8 for under $200. I doubt that the minor speed increase to 3.4 GHz will be that noticeable for most applications. Graphics cards are much more important for gaining performance in any games at this point, especially at reasonable resolutions. Sure, you can't upgrade the system that much further, but a 2.8 GHz machine should last at least a couple years from now.
