I read AMD will sell dual core cpus in 2005.
What's a dual core cpu? Is that like 2 cpu's in one package?

Define 'sell' .. do you mean to HP, or Sun, or do you mean to me/you,
and did you mean 'a few units' or 'as many as the market wants'.

>What's a dual core cpu? Is that like 2 cpu's in one package?

Essentially yes. Even better, it just drops into an existing motherboard
(if you picked the right one) and runs (if you have XP Pro, or the right
flavour of *nix). Lots of interest here ...

Yup, as will Intel. First chips are expected in about 3 months time,
though I doubt that they'll be all that widely available until the
fall.

>What's a dual core cpu? Is that like 2 cpu's in one package?

Pretty much. It's actually a single chip with 2 separate CPUs on the
same piece of silicon. It's already quickly becoming the norm for the
high-end of things, eg IBM's Power4 and Power5 chips, Sun's Ultrasparc
IV and HP's PA-RISC 8800 are all dual-core. Intel's Itanium is
expected to go dual-core this year as well, and IBM is talking about
making a dual-core PowerPC 970MP chip for use in Apple's computers.

any idea on which ones are the "right ones"...? i'm considering the Tyan
K8WE with a single cheapo opteron 244/246 to start with, and then later
upgrading to 2 speedy dual core cpus.

on linuxhardware.org tyan had this to say when asked the question on
dual core support:

--
yan) Dual core support on Tyan's Opteron platforms, is a feature we are
very much looking forward to providing to all of our current and future
customers. Unfortunately while its not possible at this time to directly
comment on whether support will be implemented on the S2885, S2895 or
other models from Tyan, customers should be pleased to know we are
working to ensure compatibility on platforms going forward.

doesn't sound very promising....

I read this the other way. Of course they cannot guarantee anything until
the processors are available and tested. Their attitude seems to be that
thay'll support their customers as best they can. I expect nothing less
from Tyan.

AMD has said repeatedly that if a motherboard meets AMD's
original thermal/power specs for Socket 940, then the dual-core
socket 940 chips will work with nothing more than a possible BIOS
upgrade needed.

HP recently demoed a machine with four dual-core Opterons.
That demo machine supposedly used a motherboard made by Tyan -
but nothing I read said whether it used one of Tyan's standard 4P
motherboards or whether it was something custom made for HP.

As well, the S289x boards use the nForce4 chipset and nVidia has
said that dual-core will work just fine with all versions of the
NF4. I can't remember if nVidia has said anything about the NF3.

Yup, I saw such a beast a few months ago on a Windows fair in
Copenhagen (was there to meet a friend, not to attend the fair. But
it was not a Tyan board, it was one of the standard HP boxes, based on
one of the AMD chipsets, as I recall. Alongside of that, there was an
OEM design also running 4 dual-cores. (It was in the AMD booth).

AMD's Dual Core 90nm Opteron Demonstration Dissected
Published: 9/2/04
http://www.amdzone.com/modules.php?o...rtid=56&page=1
Next we come to the HP Proliant DL585. Equipped with 4 940 pin CPU
sockets filled with dual core Opterons. HP has clearly put engineering
hours into the Proliant and it was well cooled and laid out. Putting
our hand to the back of the CPU exhaust revealed an airflow that was far
from hot. In fact it reminded us of our air flow test of the original
Opteron demo in San Francisco.

I did some more searching at it turns out that it is HP's xw9300
that uses the Tyan S2895: two sockets rather than 4. Lots of
sites made reference to that system, but the only one I that
mentioned dual-cores in that system was the Inquirer - so not
much credibility. The Inq said it handled the dual-cores after a
BIOS upgrade.

That was my understanding. One hopes that Tyan followed those
specifications for *all* of their products and will stand behind their
product. So far they have, IMO, which is why I prefer them. OTOH, I
haven't seen the 2875 discussed. ;-)
