Very good point. The faster Xeon has faster memory too. 2x Xeon 5410: 16GB Reg ECC DDR2-667 FBDIMM memory 2x Xeon 5472: 16GB Reg ECC DDR2-800 FBDIMM memory 2x Opteron 2352: 16GB ECC Reg. DDR2-667 SDRAM memory 8 dimms in the Xeon systems, not sure about the Opteron. -Tom > > of course, the real question is how well Nehalem will do - > does anyone have numbers? it's a sticky time for specifying > clusters, since current Intel chips have great onchip performance > but are dramatically constrained in decent-sized HPC apps. > choosing AMD, while defensible based on current memory performance, > looks extremely iffy otherwise.
