Dell Rejects AMD Chips (again)
LarsWestergren writes "A few months ago Slashdot reported that Dell was considering using AMD for server CPUs, but most people rightly remained sceptical since Dell has announced this several times before and always backed out. Well, according to the Register you were right to be sceptical." From the article: "Dell, however, doesn't seem concerned by these pricing issues or the fact that Opteron outperforms Xeon on numerous benchmarks. 'We believe that Intel has responded,' Rollins said in the wire report. 'That is now beginning to put customers more at ease that they don't need to make a shift (to AMD).'"
The 64bit portions of intel's CPUs are a kludge compared to AMD's. While they maintain almost perfect compatibility with the spec as per AMD's definition, intel CPUs cannot address >4GB RAM the same way. They use pointers to address this. Read Redhat's documentation on how they futzed with the kernel for intel's "64bit" CPUs so they could handle >4GB w/o all kinds of problems. Intel's CPUs run hotter (and while you think this does not matter, it causes issues for the life of components as well as the user ending up with slower and possibly less stable hardware. Dust can cause severe problems for heat and in turn cause the CPU to throttle back and lower speed. Way to go overpriced CPU) AMD's offerings in that area are superior. The only things intel has in its favor is marketing and 3d party vendor support. The new Nvidia Nforce4 Pro chipsets make AMD's Opteron line only more attractive.
