AMD Phenom 32-bit vs. 64-bit Linux
Phoronix: AMD Phenom 32-bit vs. 64-bit Linux
Since publishing our Linux review of the AMD Phenom 9500 on the Spider platform a month ago, we have continued in our investigation of this first AMD desktop quad-core processor that has been very problematic with Ubuntu 7.10 Linux. Fortunately though this support isn't stagnate and a better picture is painted when using the latest development builds of Ubuntu 8.04 "Hardy Heron" with the Linux 2.6.24 kernel. Per reader requests, we have carried out additional benchmarks of the Phenom 9500 to compare its 32-bit and 64-bit Linux performance.
