Rob - Re: "So if you want a low-cost high-powered 64-bit
desktop wait for the .18 micron 21264, 15 million transistors , two shrinks down from .35 micron (initial
21264) should put it in the 110-120 mm2 range, i.e. cheap.
Boxes in April at the latest I'd say"
Oh ??
I guess that's a SIX MONTH SLIP at LEAST !!!!
The 750 MHz parts are due to ship
in August, the 800 MHz EV67 and 833 MHz EV68 shipping in November.
933 MHz EV68 in February copper and aluminum parts at that time.

<Remember that the Alpha 21264 was a year late. Not only that, but it performed about 33% lower than previous expectations of 40 SpecInt and 60 SpecFP. (Initial parts scored 24 and 40, respectively. They can only go up from there, but it will be a while before the original targets will have been met.)>
You got the late part correct... the rest of it isn't correct. The
21264 shipped at 30 SpecInt95 just what Jim Keller described were
the initial target Specs from his Oct. 1996 MicroProcessor Forum
presentation. You can root around mdronline.com and
find it. You can also find 30 SpecInt95 numbers for the 8400 at
specbench.org site... 47 SpecFp95 if I recall correctly
which is VERY close to the 1996 estimate of 50.
The 667 MHz parts will exceed the original targets, shipping now
from Samsung in the UP2000 MB. The 750 MHz parts are due to ship
in August, the 800 MHz EV67 and 833 MHz EV68 shipping in November.
933 MHz EV68 in February copper and aluminum parts at that time. 1 GHz end of Q2 2000, 1.2 GHz end of 2000 and finally Samsung talks of
getting to 1.5 GHz in .18 SOI... Frankly, I believe 1.2 GHz.. and earlier targets... 1.5 GHz may be posturing on their part (we'll
see).
Note this good TechWeb article talks of low-cost Alpha.. i.e.
EV68 shrink:
techweb.com
"The company will also tip word of a low-cost version of
the Alpha 21264 processor it plans to produce early next
year, and it will demo a 1-GHz version of the chip that is
expected to ship in next year's second quarter."
Probably a $400 part in that box.
That in combination with UP1000 (based on Irongate chipset) will allow
for "loaded" boxes to get in the engineering desktop sweet spot
of $2500-$3500.. today Samsung talks of 750 MHz EV67 and UP1000
hitting $3500 in August timeframe.
Want to guess SpecInts and Fps? Better or worse than Merced?
(Hint: EV67 parts at 700 MHz reportedly do 42 SpecInt95)
By the way, what do you consider "will be a while?" Does today
count as "a while?"
How's that low-cost IA64?

So, Rob - what is Compaq shipping TODAY ??
And....do they have any recent design wins ?
