Intel vs AMD...FSB Wars!!!

[Stumpjumper5200]

Wow, fsb speeds are about to get HUGE. Well, effective speeds at least :D

Intel's decided to change Prescott's 166fsb (664mhz) to a 200fsb (800mhz)! And it'll have a 1Mb L2 cache!

Now for the REALLY fun suff: (mind you these are not offical, but it's kinda fun to toy with rumors)

AMD's Hammer line may have an effective 800mhz fsb!!! (Probably 200quad-pumped like Intel....???) If this is true, AMD would have the 64-bit technology PLUS huge bandwidth AND their performance per mhz. OMG, Intel better let those clock speeds FLY. :D

And in a few years, Intel will come out with the Tejas core, the processor that will replace Prescott. Rumors here include 64/32-bit technology like the Hammer and a 1.2GHZ FSB!!! (300mhz!!!)

And my system doesn't even run stable past 145fsb...ROFL!:eek:

Hammer's "FSB" that's 800MHz is the hypertransport link, which, as I recall is 32-bits wide on the Clawhammers (maybe it was 16, who knows). This would offer an effective bandwidth of 3.2 GB/sec, compared to the current Northwood's 64-bit wide 533FSB that offers 4.2 GB/sec.
I should mention that the hypertransport link is only used to communicate with other chips such as the south bridge and peripherals (such as the AGP port or the PCI bus), so 3.2 GB/sec is plenty. Hammer will also have a separate dedicated channel via its onboard memory controller running at 333DDR (166MHz DDR) to memory.
Comparison between this model and the unified FSB (i.e. everything goes through the FSB, including memory and accesses to other devices) of the P4 and Prescott is best avoided as there is no direct way to compare the two.

too deep... just too deep...

but... compeitition is always good... the consumer will be benefitted.... without AMD.... intel will still selling their flagship cpu @ US$1000 or more....

Not to mention alot slower. If it weren't for AMD really pushing to break the "Gigahertz Barrier" Intel wouldn't plan out chips this fast and far ahead.

As for the Hammer i heard it was Dual Channel DDRII at 200mhz double pumped to 400DDR at 128 bits a channel,and was able to get like 6.4gigs bandwidth. This info is probably old(months ago) or inaccurite tho.

I haven't heard of the initial Hammers using DDRII. The chips probably won't support it until their second revision in the second half of next year. Of course, what it "supports" is always a moving target.

One problem with the Hammer design is each chip is locked into a specific memory type due to the integrated memory controller. If you buy a Hammer designed for DDR400, it's pretty much guaranteed to not support DDRII.

Yeah, that might turn out to be a major problem for AMD. "Oh so now you want this processor with THAT kind of memory......well, first you have to buy a new processor...."

Not being able to transfer a processor to a different mobo with better memory because it's built into the chip?? Even Intel didn't go THAT low!!!
