Re: <New AMD chip to wait for fast bus >

The beauty about the AMD K6-3D is, unlike the PII-350 and 400, it is not clock-multiplier locked. That means you can insert it in an ordinary socket 7 board, use 66x4 or 66x4.5,(or even 66x5) and get up to the stated clock speed. When the super-7 boards become available in volume (and an MVP3 board has already been available in Hong Kong for over a month on retail shelves), users can simply upgrade their motherboard ($100) and get a 15% boost in performance. They don't even need to change their DRAM since the MVP3 can use a 66MHz memory bus while accessing the L2 cache at 100MHz. Since most MVP3 board will have either 512 or 1024 kB of PBSRAM, the speed of the memory is not as crucial to performance. As for Intel, their PII350 and 400 are locked at 3.5x and 4x, which means you cannot run these chips at their stated clock frequency with a 66mHz bus. That means a lot of expense upgrading the motherboard (>$165) and DIMMS (PC100 DIMMS cost 2x as much). On the other hand, the 66MHz processors can be easily overclocked with a 100MHz board, which would persuade users to run a PII-266 at 350MHz (easily). Isn't this decision dumb or what!
