Dothan vs the World

Omega65 May 23, 2004 7:18 AM ET in Tech

X86-Secrets takes the Dothan and compares it to the top X86 architecures available. There are clock for clock CPU comparisons as well as 2.4ghz overclocked Dothan benchmarks! The article is in French but the graphs are universal.

I thought I posted this before…well better late than never

    HOLY ****!!!!

    If it only had a higher FPU it would no doubt win every test out there. They should be able to make up the performance difference by moving to a 133 MHz FSB.

    Dothan: The best CPU ever made. If it was only for the desktop.

    Dothan is the second best CPU ever made. The Opteron is first in that realm. Simply because the Dothan is ridiculously efficient, but is missing the bells and whistles of a desktop processor like specific registers, a better FPU and a higher bus speed.

    But, if they fixed all those issues and released it in a Xeon/P4 Successor as has been seen more than once, I wouldn't be morally-offended by purchasing one.

    holy hell....so did intel go the way of amd and fix structural issues instead of just increasing the fsb and ghz? i'm not really 'up' on how exactly processors work as long as they do lol

    Yes, that is precisely what Intel did with the Banias and the Dothan (Pentium-M chips).

    mmonnin... there are a number of Desktop Banias boards that *should* work with the dothan- Commell has an itx one that you can get with either a mini-agp or a mini-pci slot, along with a full-size pci slot. RadiSys has a mATX board with an AGP slot. Both boards have internal connectors for LVDS LCD displays, keyboards, and mice, and the Commell board only needs a +12v power supply, and it has both an atx12v connector and an external barrel plug, at least if I remember correctly.

    so if they went amd's route, how come these things aren't hot enough to fry an egg on?? amds suffer from tons of heat (well, maybe not _suffer_...perhaps an affliction is more like it lol) due to how they're designed, and p4s are cooler because of design. so how'd they make this thing kick the crap out of a 3.4 and a 3.2EE (i think that's what they were) and not make it double as a space heater?

    P4s run hotter than any Athlon to date, so much so that Intel lies about their thermal output to disguise this fact.

    First, the idea that the P4 runs cooler than the Athlon XP is a farce. It's a myth. It's like saying that "aluminum cases cool better". It has no foundation in fact what-so-ever.

    Second, the Pentium M is a mobile CPU. It was designed from the ground up to have low power consumption and heat output. The Mobile Athlon XPs and P4ms also run very cool. Right now, my 2600m in the KX7, which is sitting on my desk, has a SLK-800 with a 50cfm Sunon fan on it. I'm ducting outside air onto the heatsink, not because it needs it, but just for the hell of it. It's like 65*F outside right now. The CPU is at 2.2GHz and 1.45v, it's under full load, and it's running at 25*C. The board temperature is also 25*C.

    hm ... just always seems like whenever anyone says their amd's idle temp (not mobile ones) it's usually around 40*C give or take. my 2.8 @3.2c idles at 23*C give or take. under load, i think they usually come pretty close to each other.

    P4's have automatic speed throttling to prevent overheating. Your P4 2.8C @ 3.2ghz may actually be idling at ~1.6ghz

    and wouldn't that be visible? not only in performance, but in CPU-Z or any of those sorts of programs? and it it's to prevent overheating the time when it would do that would be at load when it's actually hot, not idling.

    It indeed would be noticeable in performance. The throttling though, is not invoked if the CPU is well-cooled. Noticeable in monitoring software? Don't know.

    Pentium M. Got two Centrino system laptops at the office. Excellent design, execution, and performance. Intel hit a home run with them.

    No the Freq doesn't actually change, only a % of the cycles do anything while idling. You can say it's better at saving power than the Athlon.

    All along Leo, I've maintained that I hate Intel for their constant barrage of Pentium 4 bull****. If they changed their tune, then perhaps I could view them in a mildly favourable light.

    Well those graphs illustrate quite nicely why intel decided to bury the PIV.
    Those benches looks nice, if the numbers are correct.
    I believe a desktop P-M could indeed be a nice processor.
    Intel still lacks a 64-bit desktop processor though.

    Intel's next desktop CPU is a Pentium M/Dothan descendant codenamed "Merom" I believe. I would expect that this chip would be fully 64bit capapble. It's not due until 2006

    Interesting.

    I heard something about a 32bit desktop P-M moved forward to 2005.
    The original plan was to introduce it in 2006, according to various news sources.
    This change of plans should be one of the main reasons why they scrapped the Tejas.
    Well that and the fact that PresHot is hotter than a supernova.

Hey, be nice. Icrontic is full of good people, we promise.
