dual - dual core solutions?

[opcode]

Does AMD and Intel have any dual core chips that work in SMP so that you could put 2 of them together essentially making it a quad system?

If so, which core? And what would be a recommended motherboard to place these in?

I currently run a Tyan Thunder K8WE mb with dual opteron 275's, so yup, at least AMD does. I don't know about Intel.

You would be looking at a dual Socket 940 motherboard like the Tyan Thunder K8WE or a K8HM for even more memory capacity (but has a bigger form factor) and a pair of Opteron 260 to 285 (1.6 to 2.6GHz Italy cores). I'm sure there are many other high end server motherboards that you could consider as well.

All Socket 940 motherboards require Registered DDR memory.

You would end up with an expensive(ish) but powerfull workstation, especially if you tackle SMP aware, CPU intensive tasks.

Entry level servers and workstations with two processors dominate the SMP market today. The most popular entry level SMP systems use the x86 instruction set architecture and are based on Intel’s Xeon processors or AMD’s Athlon MP, Athlon 64 X2 or Opteron 200 series processors. Other readily available non-x86 processor choices in the same market are the Sun Microsystems UltraSPARC, Fujitsu SPARC64, SGI MIPS, Intel Itanium, Hewlett Packard PA-RISC, Hewlett-Packard (formerly Compaq formerly Digital Equipment Corporation) DEC Alpha, IBM's POWER and Apple Computer PowerPC processors. In all cases, these systems are available in uniprocessor versions as well.

I would love to see a benchmark of those dual op 275s crunching distributed.net's RC5-72. How many keys/sec? Anyone care to guess? 😀

Intel does have some DC Xeons, at least it says so on their website. But I have not been able to see any on any vendor websites. If you were to get a hold of two and put them in a dual-socket board, that would work. But Opteron 265-285 models are widely available and generally work better than Xeons, so I'd spring for two of them versus two Xeon DC's.
