MAYNARD, Mass., Feb. 2 /PRNewswire/ -- Digital Equipment Corporation
(NYSE: DEC - news) today introduced the Alpha 21264 family, a new
generation of the 64-bit Alpha architecture that will break the
GigaHertz (1,000MHz) speed barrier and continue Alpha's industry
performance leadership over all other architectures.
------------------------------------------------------------------------------

That's all, plus a major P.R. orgy.

In case anyone cares, actual bits:

21264 ought to be in volume in "second quarter", in "Spring", in "a
couple-three months" (from 21st of January), in 0.35 um at 400 MHz up
to 600 MHz. (So maybe mortals can get them this summer?)

The 0.25 um 21264A from Samsung (a quarter later?) will go to 800 Mhz.

The 0.18 shrink, I've no idea.

In a presentation for ISSCC Samsung will be talking about some 833 MHz
SRAM and they mention off-hand the bandwidth when plugged into an 800
MHz bus with a 1200 MHz supercooled 21264A at the other end. Make of
that what ye will.

Also, the code we used to crack ECCp-89 does 525 K iters/sec on a 400
MHz 21264 prototype. The code was tuned for my 500 Mhz 21164A which
does 388 K. I only managed to coax 48 K out of a 200 MHz PPro.

While I'm at it, gratuitous plug: soak up your spare cycles on
ECC2-89! Head over to;

Grab the 32-bit or 64-bit code. Run it on Linux, NetBSD, NextStep,
Irix, Digital Unix etc. (or even RISC OS or VMS if you ask me for
source). We're half way through so if you don't hurry, this chance of
a lifetime will pass you by! Make money now! XXX-rated live sex!
No, actually, just some source code and stats on our progress.

Bah,
Rob.
