"Benchmark Challenge: Nehalem Versus Istanbul
Wondering how the new quad-core Intel Nehalem (Xeon 5500 series) and six-Core AMD Istanbul (Opteron 2400 series) stack up against each other on HPC-style codes? The folks at Advanced Clustering Technologies, a company that builds customized HPC clusters from standard components, have been putting the latest high-end x86 silicon through its paces, and have generated some interesting results. Company engineers there ran the High Performance Linpack (HPL) benchmark on comparable Nehalem- and Istanbul-based machines, and reported their findings on the firm's Web site."
