John Guest Posts: n/a	In our company we are currently in the process of buying two new PC's for Fluent CFD work. Average number of cells for a run is approx 0.5-1 million. In some benchmark tests the P4 seems to be faster for memory intensive work because of it larger bandwith from the CPU to the memory. Has anyone done a comparison between both processors for fairly large grids ? For most tasks we buy AMD processors, because their price is attractive with good performance, but for the CFD work a P4 might be better ? Regards, John
