    Lets make sure we're comparing apples to apples. The 400 MHz bus on the Athlon is a DDR doublepumped bus, so its really 200 MHz. The 800 MHz FSB on the P4 is a quadpumped bus, so its really 200 MHz.

      Yes, and the peak bandwidth of the double-pumped 200 MHz Athlon bus is 3.2 GB/s, and the peak bandwidth of the quad-pumped 200 MHz P4 bus is 6.4 GB/s.

      So factoring the double/pumped into frequency gives the more realistic performance picture.

      Yes, but calling it "Mhz" is misleading. That's like saying the PCI bus runs at 1056Mhz because it is 32 lines running at 33Mhz.

      We already have enough misleading and confusing computer terms, we don't need to add another one.

      Does it give the more realistic picture? I'm not a hardware designer or anything, but I've always been under the strong impression that the front-side bus speed mainly matters when you have a memory access. In that case, what really is going to make a difference isn't bandwidth. Instead, it's latency.

      I'm assuming that when something isn't in the cache, the processor is going to read a whole line at a time, but will start with the word actually needed and then fill the rest of the cache line after that. In that case, the processor only has to sit and wait while just one word is fetched from RAM. So what really matters is not how fast you can stream in multiple words, but how fast you can read in one word. (Of course, there are times when streaming in lots of data is helpful, such as when the processor isn't mainly hitting its cache but instead is copying a large block of memory...)

      As I said, I am not an expert, and there is always the possibility that doubling or quadrupling the data rate will reduce the latency of memory reads as well as increasing the bandwidth. If so, I'd love to be enlightened about this topic...

      The thing with overclocking usually isn't to get the newest, and fastest CPU and then overclock the hell of it. It's to get something in the midrange and then overclock. For instance, when the Barton core was first released you didn't see curious overclockers buying 3000+ parts to overclock, no they (myself included) purchased the 2500+ part at a savings of roughly $400. I can overclock my 2500+ up to what SiSoft Sandra says is 3200+ performance specs with very little noise a-la my watercooling system. I needed a watercooler anyway due to the high temperatures in the summer in my room, and guess what? It's completely stable. People won't buy the 3200+ CPU's en mass to overclock them, but they will buy the boards updated to run the 400Mhz bus so that they can overclock their old 266 and 333Mhz bus CPU's in a more stable environment.

      I'm going to assume that you are trolling, but as I'm an angler myself I can appreciate a good set of inline blades.

      What I don't think you understand about the CPU business is that when Intel, AMD, whomever makes CPUs, they make them without knowing which one will end up going what speed. It's not until they test them that they find out, and then they put them into a bin based on the max speed they run.

      Well, let's say that they have a good run and they get 60% of them to go at 3000+ speeds, with the rest waterfalling down from there. That's great, but the market isn't demanding a bunch of 3000+ chips. Turns out the big push is for, say, 2400+ chips. So, to fill those orders they set many of those faster chips to run at the 2400+ speeds via the cutting of bridges.

      Why not just release all those 3000+ chips at 3000+ speeds? Profit, dear troll, profit. If they flooded the market with those higher-priced chips, then the price would go down. Better to make a large profit on those fewer faster chips.

      At least, that's how I understand it.

    Acording to my sources, this should be the last Athlon XP to be released by AMD. Their next desktop processor will probably be Athlon 64, wich will need a different motherboard.

    So my advice is for not buying a computer with Atlhon XP 3200, as your upgrade roadmap will be locked. It is better to buy a computer with a slower (and cheaper) Athlon, and wait untill the price drop to buy an Atlon XP 3200. Or wait for the release of Athlon 64 - it will be an excelent computer for video edition, 3D rendering and games like Unreal Tournament 2003 or Doom III.

    Now I browse with many windows, 24bit colour at higher resolutions (rarely anything as pathetic as 1024x768).
    I can play mp3's without skipping a beat, along with movies. I was glad to get a .mod playing on my 386 without skipping.

    AMD CPUs outperform Intel CPUs at similar frequencies. That's why AMD stopped marketing their processors based on their frequency. In some benchmarks, an Itanium running at 900 MHz outperforms 3 GHz Pentium IVs. Once upon a time, before clock multiplying, MHz meant more than it does now. But even in the 8-bit days, a 6502 running at 1 MHz would perform similarly to an 8086 running at 4.3 MHz.

      I think you mean 8080 or Z-80, not 8086... The 8086 is a 16-bit processor with a 20-bit address space (IIRC). The 8088 was an 8086 with an 8-bit data bus. The 8080 (and faster clone, the Zilog Z-80) was an 8-bit processor.

      The 6502 (1 MHz) compared so well against the higher-clocked 8080/Z-80 (usually 4-5 MHz) because of better pipelining and shorter instruction cycle times (IIRC).

    I wouldn't blame the chipsets right away... Most problems as you've described are caused by the motherboard itself. It's a well known fact in the IT world that ECS motherboards are crap, and are oftentimes expected to crash.. i.e. it's an anomoly to have one run stable for more than 3 days. Same deal with Abit, Tiger, and to an extent Asus. The latter manufacturers put more of an emphasis on performance than stability. For the past 3 years I've worked as a system builder and technician for a small company, and have worked with virtualy every motherboard manufacturer on the planet. I've seen a number of very stable motherboards, mainly from MSI, Biostar, DFI, and a few others, with VIA chipsets, and not one of them had any sort of hardware problems, once all drivers are properly installed. I have seen and heard of many issues with SiS chipsets, but VIA is rock solid when integrated properly by a manufacturer.

    That comparison is kind of difficult because when you compare the most expensive AMD to a similarly priced Intel chip the AMD is only a marginally better value, but as the prices go down the AMD power/dollar advantage gets larger.

    Example: ~$320 will get you an AMD Athlon XP 3000, the most similarly priced Intel P4 is their 2.8GHz for ~$300, you're only getting a slight price advantage with AMD. However for ~$90 you can get a 1.6GHz Intel P4 or an AMD Athlon XP 2400.

If you didn't know, Quake 3 has always run faster on P4's than on Athalons. To be fair, he should have also benched something like Serious Sam 2 which has a similar advantage on AMD chips. I would be similarily suspicious of his other benchmarks, like mp3 and mpeg encoding. If he knowingly uses a game that's better optimized for one processor in a benchmark, whats to stop him from doing the same in others?

    Remember that Tom plays favorites with Intel and AMD, depending on who's giving him more free stuff these days. A year or two ago he was loudly claiming there was no way Intel would be able to compete with AMD and that they'd end up exiting the consumer processor business.

    Perhaps from a marketting perspective, but certainly not from a technological perspective. We took a $13,000 quad P3-Xeon machine, replaced it with a $3,000 dual AthlonMP, and guess what - the loads dropped in *half*.

    They were (and are) very good performers. Their only limitation was a memory bandwidth limit. AMD went to all of the trouble to give each AthlonMP it's own independent bus, but they never took the time to mate that with a dual-channel memory controller, so that each processer could actually *utilize* the entirety of it's bus. Even so, they were (and still are) very capable machines.

    Barton (Model 10) comes in three flavors: 3000+ (2.167 GHz), 2800+ (2.083 GHz) and 2500+ (1.83 GHz). All other things equal, the 3200+ should run at 2.25 GHz, same as the 2800+ Thoroughbred (Model 8).

    However, if AMD were to increase the FSB speed, you can expect the CPU frequency to be slightly lower. I would guess between 2.083 and 2.167 Ghz.
