  3. Choked Bus? by rice_web · · Score: 4, Informative

    This upgrade raises the concern of the choked bus. I mean, who really wants to run a 3000+ on a 133MHz system bus?

    I do, and benchmarks have consistently shown that an increase in bandwidth for the Athlon rarely produces a substantial increase in speed (i.e. the recent speed "jumps" from AMD).

      In Quake3 and most of the other benchmarks the CPU with a 133MHz bus @ 2.133GHz performs worse than the cpu running with a 166MHz bus at 1.833GHz.

      The Athlon is comparatively simple, and the 400MHz FSB is overkill.

      This isn't because of simplicity - it has to do with the size of cache lines in the L2 cache. The P4 fetches larger blocks with each miss, meaning a longer wait when a miss occurs. The Athlon, making smaller fetches, requires less bandwidth for a given miss. Obviously, if you designed worst-case code that was aimed at generating pure misses, both processors would be abbysmal and heavily affected by FSB, but normal code is not like that.

      Take a look at the pipeline stages and you'll see that we're on the same page. The Athlon has many fewer pipeline stages (one reason that the Athlon typically beats the P4 at the same clock speed) than the Pentium IV. As you said, the "P4 fetches larger blocks with each miss", and that's true, thanks to its larger pipeline.

      ...thanks to its larger pipeline.

      You can set cache line size to any arbitrary length when you design a processor. Now, because of the longer pipeline and higher clocks of the P4, I believe that larger cache lines make more sense, but you don't inherently need longer cache lines when you have a longer pipeline.

    The two main PC parts stores (small private stores, not the big-box retailers) have had no-return policies on CPUs for a while now. Once you buy it, you have to go to the manufacturer if anything is wrong. They are willing to drop it into a system before you leave the store to check it is not DOA. Best Buy, etc, may have different return policies, but I don't know anyone that is into OC'ing that would buy a CPU at an overpriced place like BB.

    It is? If you're having trouble with the stability of your system, it's most probably either your Power Supply Unit or RAM, don't blame the CPU.

    I have an "Athlon System" with good RAM and CPU and it hasn't been down in about 3 years.

    "How in the hell do you conclude that anyone that wants to overclock is likely to be a liar as well?"

    That is not my conclusion. My conclusion is that someone is going to notice the selling point for this particular adaptor, namely what I quoted with a stress on "The warranty of your processor can be kept alive." And will think they now have a risk-free overclocking experience.

    I have NO problems with people that want to overclock and risk burning out their system, as long as they don't ask for a refund the next day. You can overclock it, use it as a paperweight, or use it as a heater in the Winter for all I care.

    The example I gave of Joe Smith returning his CPU was in the context of what the original company was pushing, not a general statement of overclockers.

    So now stores that sell these CPUs now have even less to work with when determining whether John Smith walking into the store asking for a CPU exchange actually had a faulty CPU to begin with or was doing mad l33t overclocking in his basement last night.

    As someone that's worked for a computer store, who gives a shit? If there's nothing on the CPU indicating it's been tampered with or abused, then the retailer can make a warranty/DOA claim with their distributor/supplier and won't be left out of pocket, since if there's no way the store can prove the CPU was abused, there's no way the distributor can, either!

  11. 2600+ isn't a Barton chip... by WIAKywbfatw · · Score: 5, Informative

    An Athlon XP 2600+ isn't a Barton core chip, it's a Thoroughbred "B" chip.

    The Barton core chips are:

    Barton 3200+ (2.250GHz, 512KB cache);
    Barton 3000+ (2.167GHz, 512KB L2 cache);
    Barton 2800+ (2.083GHz, 512KB L2 cache);
    Barton 2500+ (1.833GHz, 512KB L2 cache).

    The top Thorougbred core chips are:

    Thoroughbred 2800+ (2.250GHz, 256KB L2 cache);
    Thoroughbred 2700+ (2.167GHz, 256KB L2 cache);
    Thoroughbred 2600+ (2.083GHz, 256KB L2 cache);
    Thoroughbred 2400+ (2.000GHz, 256KB L2 cache).

    Note the increased L2 cache size on the Barton, which AMD cite as the reason for the 200-300 point rise in their performance rating for those chips (eg, Barton 2.167 GHz = Thoroughbred 2.167GHz + 300). Obviously, the latest FSB bump introduced with the Barton family helps too.

    In some situations a Thoroughbred 2800+ will outpace a Barton 3000+ because of it's greater clock speed but, in most cases, the Barton with its greater L2 cache will win out.

    Anyhow, given this story is about "overclockers looking to upgrade their age old Athlon mobo (KT133, KT266 etc.) with a spanking new AMD Barton CPU", I thought it prudent to point out your incorrect assumption about the XP 2600+ chip.

    In all likelyhood, you probably wouldn't need any sort of adapter to fit a Thoroughbred chip to most older Athlon motherboards - I know that I could swap the 1.2GHz CPU in my machine for a 2800+ with no hassle but wouldn't be able to do the same with a 3200+, or even a 2500+.

    But if you're really going to skip the 2800+ for the 3000+ or 3200+, then you're paying 50 percent or 110 percent more for your CPU in the first place. And if you're doing that, then you might as well be buying a new motherboard.

    I wouldn't touch a VIA chipset! Utter crap. I have an old motherboard KT133 which I was thinking of using in my Linux fileserver, but I remembered how much trouble I had with it in Windows.

    The problem is the PCI implementation is flawed (to put it mildly) and especially since my fileserver on an old Intel 440BX runs a software raid array with 3 IDE controllers (including onboard), we're talking serious PCI usage here. Definately NOT a job for VIA.

    My desktop (windows) is running an nForce2 and its rock solid.

    So remember: VIA? JUST SAY NO!
