And one such system integrator has revealed to us a cunning plan that speeds up performance of what AMD hopes is a Xeon-killer and Intel hopes is just a flash in the pan.
One integrator told the INQ today: "The Intel compilers are by far the best for optimising X86 but of course do not recognise an AMD Opteron."
He continued: "The Opteron has SSE2 support, but to get a binary calling SSE2 one has to compile the binary on a Xeon machine. Move the binary over to the Opteron box and it flies." Further - the integrator, who sells Intel server machines too, he claimed that the SMP performance is excellent on the Opteron platform. He said: "Typical SMP benchmarks in HPC show about a 30% gain with 2 CPUs over one on a Xeon/P4 platform. The same tests on Opteron show an 80% gain". µ
* Meanwhile, an article by microprocessor maven Andreas Stiller at c't magazine in Germany has released performance figures that appear to show that the 32-way NEC Express 5800, a 32-way Itanium system, seriously underperforms the 32-way Hewlett Packard GS1280, the latter using the Alpha microprocessor, currently in its death agonies. You can find that here, and you should also click on the "SAP-SD-Benchmark-Werten" link.
