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.

    However the real question is, how many decision-makers are reading these review/benchmarks, or do they just buy Intel because it's Intel, or that's what xx-business weekly says?

      You may have forgotten the memory bandwidth. That leap from 533MHz FSB to 800MHz FSB was accompanied by a huge leap in memory bandwidth from single-channel DDR266/333 (845PE chipset) to dual-channel DDR400 (865/875 chipsets). There were no memory bandwidth increases to go along with today's leap to 1066MHz FSB.

      Also, the Anandtech article notes that Pentium 4 Extreme Edition doesn't use its FSB as much as the non-Extreme because the P4EE has a large 2MB on-die 8-way associative L3 cache.

      I disagree. I've been running 64bit Gentoo (amd64) for some time now.

      Many apps don't even compile under amd64, but the most important ones do (as they are tested/fixed first or have been running on 64bit platforms before). There is still a lot to do. There is no 64bit flash. There are no 64 bit accelerated drivers for ATI cards. For some reason even OpenOffice does not compile or work well in amd64 (a 32bit version can be used however).

      Under Gentoo (possibly other distros, I have not checked) you can run normal 32 bit binaries if you install compatiblity libraries and kernel support. This can be used to run those apps that do not compile in 64bit. These mixed environments bring their own problems though. The most obvious one is diskspace. Compiling must be done under a complete 32bit chroot enviromentand thus requires a seperate 32bit install.

      In short, running a clean 64bit linux environment is a pain. Too many apps are not tested yet. Very little closed source linux apps (skype for example) and (closed source) drivers actually run under amd64. Many verdors' linux support is limited... their 64bit linux support is usually best described as "absent".

      Well, you can disagree, but I didn't really make a straight point for you to exactly disagree with.

      Disk space should really not be a concern these days. When you can buy a 200GB drive for $120 at Best Buy, I can't see this as being a big issue.

      But the other problems, well, I don't own an Athlon 64 yet so I couldn't say one way or another for sure if it's worth the trouble. As far as I've heard, the 32-bit drivers for the ATI suck anyways =) nVidia supplies AMD64 drivers, so that's a nice thing (I don't care what anyone says, I think it's great to have nVidia supporting Linux even if they don't open source the thing.)

      I'm sure you have to install compatibility layers on all distributions, just as Windows 64 must do the same (Microsoft uses the old Windows on Windows trick they did with Win16 apps.) On other distributions this may be a lot less of a headache since you usually don't have to compile everything, but at the same time it will likely cause trouble with some packages that aren't expecting to find some 64-bit libraries in place of 32-bit ones.

      AMD64 does bring a complex set of issues to the table - we want compatibility to run 32-bit stuff and we want to run 64-bit native when possible. Although I have seen some dispair with Linux on AMD64, it really hasn't been too bad yet and considering what it is, it sounds like there's some resonable drawbacks at this point. Since all the source code for most apps is available, getting stuff to run in AMD64 is probably not too daunting of a task.

      And you're lucky if you can get OpenOffice to compile on anything, nevermind AMD64! I've set up a clean, new Gentoo box and tried to install OO with all the correct versions of whatever it needs, and STILL have it fail on me. Of course, there's a chance you could get it to work, and that's more then AMD64, at least. But like you said, you can use the 32 bit version.

      There's a few closed source games that seem to work normally in AMD64, such as Doom3 and UT. I presume that once all those "EMT64" chips from Intel start being used more, with the popularity of the Athlon 64's, all these bugs will be worked out in due time, and it will probably help other 64-bit platforms in doing so. I'm always amazed at the speed in which OSS software moves.

      Good information, though. I'm planning on getting a couple Athlon 64's soon, one for Linux and one for Windows.

      You are quite correct in stating OO moves fast and that the availability of source makes porting things seem "not too daunting". Please do not forget however the huge amount of available packages and the limited amount of amd64 owners who are both willing to run 64bit environments and capable of fixing bugs.

      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.

    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.

    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.

Sometimes you'd rather optimize for space, and so you use the smallest integer size that is large enough for the task at hand. In the few places where your code really could take advantage of very large integers, you can change those to long longs.

Keep in mind that if you change the size of time_t, you automatically break binary compatibility with any library or system calls that use time_t. A better plan would be to have something like a time64_t and accompanying new library and system calls.

    Presumably they did this for backward compatibility, then broke it by making size_t 64bit

    This doesn't break anything. There was never any guarantee that a size_t would fit inside a long, so any code that assumed so was nonportable to begin with. If you're storing a size_t, you should use a size_t variable.
