There are several posts on the Forum about Intel 7/AMD dating back<br> to 2009, but I do not see anything about the PC using the newest FX AMD processors.<br> Right now it is possible to build FX8350 (8core, 4 GHz, 16GB memory) for less than $700.00,<br> or with 32 GB memory for additional $150.00. <br></blockquote></div><div><br></div>I personally never heard about HPC systems or high-end server for HPC based on AMD microprocessor with Piledriver microarchitecture. Based on wikipedia this Piledriver architecture implements the same "module" philosophy of AMD Bulldozer. So one floating-point scheduler unit that dispatches FP calculations inside two distinct pipelines each one 128-bit wide. How efficiently FP operations are scheduled… no idea. I probably need to study more how Bulldozer AMD architecture works.</div><div><br></div><div>From a pure QE perspective, we do not have the possibility to try every single CPU architecture on the market. I tried QE on different HPC systems equipped with AMD Bulldozer or AMD Interlagos chips. My personal feeling is that Intel sandy bridge is better but I do not have quantitative numbers to prove my statement. I am curious too to see if some user n the mailing-list has some feedback to share about AMD FX83xx series.</div><div><br></div><div>Speaking about the memory on the system, it depends by the average size of the systems you are going to investigate. Memory is never enough… </div><div><br></div><div>Good luck</div><div>Filippo</div><div><br><div apple-content-edited="true">
