SiSoft Memory Bandwidth


In every real-world test, the performance drop with 4 DIMMs on the Pentium 4 is much more significant than the performance drop with 3 DIMMs on the Athlon64. Using tools such as the artificial SiSoftware Sandra 2004 to measure memory bandwidth can be very misleading as you can see above here. The value of this benchmark is seeing the differences in how AMD and Intel handle this increased number of memory banks, with AMD slowing down the bandwidth and Intel increasing latency.
