Mainly, we should compare UP2000 to DS20. Both are dual processor
capable with 256-bit wide memory. The DS20 has slightly higher memory
bandwidth due mostly in part to the 200-pin SODIMMs (UP200 uses 168-pin
DIMM). DS20 max. memory is 4GB compared to 2GB for UP2000. UP2000 is
available in 667MHz with 2 or 4MB cache or in 750MHz with 8MB cache. By
the way, the UP2000 with 750MHz/8M provides the highest SPECcpu95
ratings ever, both int95 and fp95. The UP2000 will be available with
1GHz 21264, when this cpu is released. We believe that this will be the
first 1GHz Alpha platform.
The chipset used in both DS20 and UP2000 is the same, Tsunami. The only
difference is the memory controller chip.
Where the DS20 has the slight edge in memory bandwidth, UP2000 makes up
for this, and more, with the faster CPU. Testing to date shows that the
UP2000/667MHz is much faster than DS20 in most areas.
UP2000 was designed specifically for Linux, it does not run Tru64 UNIX
or OpenVMS. And, well we all know where NT is going. DS20 was designed
specifically for Tru64 UNIX and can run Linux. Our testing shows that
UP2000 is overall a better choice for Linux, than DS20 - in terms of
performance, support and most importantly, pricing.
Yes, although you can squeek by (barely) with a 400W supply, if you buy
a dual CPU with a couple of storage devices.. you should really consider
600W as a minimum. With 1 CPU and 1 or 2 devices, 400W is sufficient,
provided it is of high quality.
You can receive a quote on UP2000 from
or, send me a note at chr...@harddata.com
You mean the Compac Fortran and C for linux? If so, yes.
