New Intel Chipset and Extreme Edition CPU Tested

Steve writes "Today sees the launch of both a new CPU and chipset from Intel. The CPU takes the form of a 3.46Ghz Pentium 4 Extreme Edition, running at 1066FSB, and the chipset is the i925XE, the first Intel chipset to support this new FSB. HEXUS.net have a review of both. It looks like AMD still have the lead when it comes to performance, despite Intel's attempts to counter the Athlon 64 FX-55." Hack Jandy links to more reviews at AnandTech, HardOCP, and ExtremeTech.

      Long pipelines have a few bad side effects. Of those directly impacting performance: longer latency, worse branch miss penalty.

      Now for the first one I will tell you: You do not care how latent (that is, laggy?) your processor is, as long as it is not extremely high. A lack of throughput is what slows down an application, not how long any individual instruction takes to go through the processor. This may change with multi-processor systems where something as fast as the processor (another processor) is active, but not in a conventional system. You want latency? Check out main memory.

      Now the branch miss penalty is a bigger issue. The 20 stage P4 has a 19 cycle branch miss penalty meaning that if there's a branch and it guesses incorrectly, it will lose 19 cycles worth of work. What you need to take into account is that the P4 has one of the best branch predictors ever. The P3 is 10 stages, the P4 (pre-Prescott) is 20 stages with a 30% (this is what Intel says) better branch predictor, and of course a much faster clock. The P3 would not be able to run at the faster clock time (that's the advantage of pipelining).

      The other side effects of many pipeline stages include a core size increase therefore a lower yield therefore a higher cost and longer design and redesign time, and more power consumption / heat dissipation therefore clock limited. That last one is the kicker at Intel right now. The Pentium M is Intel's rising (albeit embarrassing) star. All I know about the Pentium M's pipeline is that it is "between 10 and 20", unless Intel has said anything new.

      So I don't mean to say you're wrong, just it's not so simple. There are plenty of factors playing a roll. There may be a sweet spot in number of stages which has been exceeded, although I don't think there will ever bee a stable number.

Is it possible for Adobe to make a benchmark based on Premiere or Photoshop? Anywho, this is getting off-topic.. I'd like to see if this chip outperformed the AMD competitors in this arena.

  21. Re:64 vs. 32 by Sivar · · Score: 5, Informative
    I noticed that the summary points out how the AMD64 is faster. Well, what were you expecting, its 64bit vs. 32bit.

    If you want a fair comparison then compare the AMD 32bit processors against Intel 32bit processors.

    And compare AMD64s against Intel's 64 bit chips.

    Someone needs a gentle tap with a cluestick.

    1) Being 64-bit does not necessarily improve performance and, in fact, can degrade performance when used on the VAST majority of applications that primarily use integer numbers of less than 4.3 billion (2^32 unsigned). Take a look at Solaris/SPARC64 for an example.

    2) Even in applications that can make use of 64-bit integers, the AMD64 specification defines an "integer" as 32-bits. Software has to expressly use a "long" (or similar) to make use of the other half of the register size, and because on 95% of computers out there (read: vanilla x86 systems) a "long" is the same thing as an "int", this is done rarely at best.

    3) Even if all software in the universe could get a staggering performance boost from 64-bit registers AND were instantly tuned to use them, it wouldn't matter because all of the software used to compare the Athlon64 to the Pentium IV is 32-bit software running on a 32-bit operating system, except in the occasional tests that are designed specifically to test the benefit of the Athlon64's 64-bit mode.

    4) Even if every one of the professional review sites were manned by biased or clueless authors (generally true of Tom's Hardware and GamePC (and any review website run by your average l33t w4r3z d00d or non-technical game enthusiast), though the former appears to be improving), the 10% average gain when compiling software to use the 64-bit extentions of the Athlon64 is nowhere near the actual performance gain, in 32-bit software, that the Athlon64 has over the Pentium IV in most games and a number of other applications.

    5) Even if the performance gain of 64-bit mode was greater by far than it is now, the bulk of the performance improvement in most software is from a: the integrated memory controller (which is also used in 32-bit mode), and b: the fact that the number of general-purpose registers has doubled from 8 to 16, greatly reducing the amount of register variable swapping needed. Again, most apps simply do not care if they can fit huge numbers in a register, because they do not need them.

    So as you can see, your assertion is flawed.

  22. Intel starting to go off their rocker? by TheLink · · Score: 2, Insightful

    No. They went off their rocker more than 3 years ago when they designed the P4 and went for GHz for marketing reasons and not engineering reasons. That said the P4 actually served them well for a number of years, but they didn't get off at the right station...

    I remember Intel talking about 5-10GHz CPUs. They were probably taking a bet that the process and material engineers would save them.

    I'm sure they realized they lost the bet when the Opterons/Athlon64s started spreading their wings and actually flying, but when you have multi-billion dollar fabs, commitments to partners, it takes a while to turn the ship.

    If you observe, they've canned a lot of stuff and changed their product milestones/announcements.

    They just can't tell Dell, forget the next bunch of P4s, we're going to go Pentium-M NOW (even though we haven't got it fully buzzword compliant)!

    Any idiot can realize the Prescott was bad news ONCE it was testing. But by then it's just too late.

    AMD has a window of opportunity till at least early 2006. As long as they don't screw up! They better use overwhelming force if they want to win. It's not an easy battle. Intel is no pushover.

    I mean - what's there to prevent Intel doing the same stuff as AMD? e.g. Pentium-M with memory controller on CPU?

    Meanwhile I'm really curious about the new Intel SMP server chips. What are the power consumption and cooling requirements like?

  25. intel blew it on multiple fronts. by bani · · Score: 2, Insightful

    they sunk billions into itanic, thus wasting valuable company resources (engineers, fabs, marketing, etc) that could have been better put to use on their mainstream chips.

    then they blew it by designing p4 to purely target a mhz goal, expecting that advances in materials and fabs would easily let them scale to 10ghz.

    basically, intel was overconfident and then refused to abandon a ship (itanic) when it was obvious it was in trouble, instead desperately trying to save face and keep it afloat.

    while they were busy mending their doomed ship, the popularity of amd64 completely caught them off guard. now amd is eating their core markets for lunch.

    in the meantime, intel's itanic partners are beginning to abandon ship. this has to be really alarming to intel.

    intel is trying to go too many directions at once, all of them wrong.

    amd took the safer bet (amd64) while intel was pooh-poohing and ridiculing them over it. that decision has now come back to haunt intel.

    I've handled hundreds of AMD chips, and I've never had one single DOA broken one, ever. The only broken AMD CPU I have owned was an Athlon 900Mhz chip, because I fucked up and busted the chip by putting too much pressure while installing the heat-sink.

    I should mention that AMD not only replaced the thing for free, they sent me a 950Mhz chip, and sent it overnight delivery, no charge.

    Since then, I have been a lot more careful installing heat sinks. The Pentium 3 "flip chips" were *EXACTLY* the same as the Athlons, and you could break them just as easily.

    I call bullshit on you for that FUD. And not to mention, the Athlon 64's all have a heat spreader on them now, so your point is moot.

    AMD Processors have always treated me very well. I never have problems with them, and they always run how I expect them to run, plus some. Intel makes good CPU's too, and I use them as well.

    AMD chips used to cost very little, yes, but nowadays they're pretty much on par with Intel.

    Athlon 64 FX-55 ... 899 Euro
    Athlon 64 FX-53 ... 849 Euro

    Athlon 64 3000+ (socket 754, 2 GHz) ... 174 Euro

    Pentium 4 3000 GHz (Northwood) ... 189 Euro
    Pentium 4 3000 GHz (Prescott) ... 184 Euro

    So it looks to me like they're very much on par, as price goes.

    Now this isn't a scientific study or anything, and I didn't even try to find the lowest price or anything. I just stopped at the first online shop that came to mind.
