AMD Moving to a 400MHz Bus?
An anonymous reader writes "According to this tantalizing Infoworld Scoop, AMD soon introduce a 400 Mhz bus. Seems that SiS's big announcement at CEBIT is the SiS748 chipset, which supports both 400 MHz DDR & AGP 8X, and is targeted at the upcoming Athlon 3200+."
There have been rumors about AMD going for a 400MHz bus for quite some time now. Some chipsets even have experimental support for it. With the Athlon 64 being delayed until September I would say that is the only way for AMD to try and stay competitive with the Barton core.
Maybe I'm being a little arrogant, but I still feel this isn't really much to be that excited about.

Hmm. Yes, the K7 has gone from 500MHz to 2250MHz over its lifespan so far - but Intel's P6 core went from 150Mhz PPro to 1400MHz PIII.
Looks to me like they could still have plenty of room to play.
AMD better forget these little incremental speed bumps and switch to a whole new architecture this year if they want to remain competetive.
It's called x86-64. The Opteron ships next month.
The current architecture is like milking a deadhorse and they are already running waay too hot.
I did not need that mental image...
Current Thoroughbred and Barton core Athlons don't run all that hot. An Athlon 3000+ runs cooler than a 3GHz P4.
I reclocked my TBred core Athlon XP 1700+ to 8x202MHz (404MHz DDR) on my ASUS A7N8X Deluxe motherboard (Corsair PC3200C2 DIMM). I kept the default core voltage (1.5v). MemTest86 verified that it works reliably. Upping the FSB is mostly a matter of motherboard and memory support, not CPU support (outside of being able to adjust the clock multiplier). A few years ago I reclocked a 150MHz Pentium to 1.5x100MHz. Worked just fine.
