Does Intel give a mid-quarter update soon? Is it now a regular event?

Thanks.

RE:"Northwood (0.13 micron process) will initially launch in quarter 1 at 2.2 GHz - 400 MHz FSB, but will be succeeded by a 2.4 GHz - 533 MHz Northwood in (early) Quarter 2. It has also been confirmed that Northwood has 512 KB L2-cache on board"

Looks AMD is in big trouble...They will need a couple hundred extra Mhz by then or else...

Re: 2.4 GHz - 533 MHz Northwood in (early) Quarter 2

Northwood with expensive dual channel RDRAM - 3.2Gbytes/second

Northwood with single channel DDR266 - 2.1Gbytes/second

Northwood with single channel DDR333 - 2.7Gbytes/second

The only thing the P4 is any good for is streaming data because it has a 3.2Gbyte/second front side bus. While AMD's DDR is a superior solution to Intel's RDRAM approach, single channel DDR266 and DDR333 are both still slower than P4's FSB and neither can be run with it synchronously (as can RDRAM). PC1066 with 133x4 FSB will help P4 on artificial benchmarks that move bytes from one place in memory to another, (in real world applications, if bytes are in memory, there is rarely any reason to move them around to other locations) but P4 was designed for RDRAM, not DDR, and its FSB continues face a mis-match penalty when working with DDR.

That's the price you pay when you're a follower, and not a leader: you have to kluge your parts to work with the standard the industry leader has established. Your stuff winds up costing more and not working as well.
