    why does amd have half the front side bus speed of intell and does it matter

    When looking at the amd boards the front side bus speed is either 200 or 266 mhtz with intel boards it is 400 or 532. Are they just measured differently are are Amd processors actually half as fast. How exectly does the bus work anyway?

    intel has speed, amd has performance. benchmarks show that AMDs perform better than Intel, but Intel just has the higher hertz. That's the basics of it.

    It kinda goes back and forth like this. When the Athalon came out AMD ran at 200 and 266 MHz bus while the PIII was at 133. When AMD's next generation processor comes out (soon) it will most likely be up around the PIV.

    And the FSB is the path between the processor and the RAM. The quicker the two can talk, the faster your PC is. A 3 GHz processor running on a 100 Mhz bus would be not much faster than say, a 1 GHz processor. There would be so much latency it would be rediculas.

    That's how the bus works. Oh, and as of right now, the fastest Intel (with the 532 Mhz bus and RAM to support it) is faster than the fastest AMD

    that doesn't make a difference. speed is not everything, and it's almost nothing compared to what's really important for a processor.

    do you know what benchmarks are? well, amd has better numbers in the benchmarks. a 1600+ destroys a 2.0A+ processor in mips and mflops and integer conversions. amd does a lot better than intel in a multimedia benchmark.

    so, if all you're looking at is hertz, then the average person would say "of course intel is better, they're faster!" but, if you do a little research on results and tests then you would realize there's more to processors and AMD just is better with that.

    intel has numbers, amd has performance. that's it, and that's what it comes down to. if you want to impress your friends with a 2.5GHz cpu, and laugh at a 2000+, then you'd better step back and take a look at the bigger picture.

    Yeah.

    Performance = IPC (Instructions per clock cycle) * Clock Speed;

    I'm talking about in benchmarks

    Intel has been ahead of AMD in hertz for quite some time, but the fastest Intel has always BENCHMARKED worse than that average AMD. Untill now. The fastest of each company, as of about a month ago, Intel benchmarked faster than AMD. Not by much, but it was in PC World magazine, m'kay?

    just in case anybody's is curious as to what Hillbillie is talking about, Intel uses CISC and AMD uses RISC. summed up, cisc is complex and risc is rapid. i'm pretty sure that's correct.

    CISC

    RISC
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Hmm...did not know that.

    Ya learn something new everyday...

    debates between better processors can go on forever, based on the fact that there are so many facets to cpus and what they deal with, it's such of a copias amount of information.

    No. Both may have a RISC like core (which doesn't necessarily mean they are RISC processors), but as both are x86's they can't be different as both share the instruction set.

    point is this:

    Intel is faster.

    Intel is more stable.

    Intel is more reliable.

    Intel holds up much better in overclocking situations.

    Intel chips can pass 3ghz already, amd can't. The first 3ghz P4 was done 2 days after the release of the P4.

    Booya, AMD can suck a fat one.

    Ignorance at it's prime. I suggest you read the links Hillbillie and Joe posted. I know I learned a lot.

    i don't want to create enemies and i don't plan on doing it. but...you're wrong. tell me, do you overclock? well, i do. i am an accomplished overclocker. and i have an amd processor. sure, they generate more heat, but if you don't have the necessary cooling, you shouldn't overclock.

    >> Intel chips can pass 3ghz already, amd can't. The first 3ghz P4 was done 2 days after the release of the P4. <<

    you know, i get a kick out of this. didn't you read any above posts? speed doesn't matter!!!

    it's proven that amd is better for multimedia (do you want to see numbers? i can post benchmark results if you like) and in most cases, integer/floating operations.

    i knew this would turn into a heated debate, and amd guys aren't going to convert to Intel, and vice versa. so, let's try to keep this as civil as possible.
