We’ll start off with a little SiSoft Sandra Calculated Memory Bandwidth. When comparing the calculated memory bandwidth of both the Athlon XP and Pentium 4, the Pentium 4 has 12% more ALU and 44% in FPU. This is most likely due to the Pentium 4’s bus architecture, which uses a 400 MHz Quad Pumped and takes full advantage of the DDR memory.
Nonetheless, this is just a calculated synthetic test; let’s move on to how much memory bandwidth the processors can achieve theoretically.
New to SiSoft Sandra 2002, SiSoft Sandra’s memory bandwidth test allows an option for “buffered benchmarking” which allows the program to test and determine how much memory the processors/motherboards can achieve theoretically.
When it comes to how much memory bandwidth both processors can achieve theoretically, both processors score within 1% of each other, with the Athlon XP having more theoretical memory bandwidth. Will memory performance affect system performance? We’ll just have to see….
