Posted: April 3rd, 2002 Written by: Tuan Huynh Hardware Setup AMD Athlon XP2100+ (Palomino), Intel Pentium 4 2.4 GHz (400 MHz FSB), Gigabyte 7VRXP (KT333), Abit BD7-RAID (i845D), 2x 256MB Kingston Value Ram PC2100 (512MB), Hercules 3D Prophet III Ti500, Onboard Creative CT5880 Audio (7VRXP), Onboard Avance Logic Audio (BD7-RAID), Realtek Onboard NIC (7VRXP), D Link DFE530TX+ (BD7-RAID), Lite-On 52x CD-Rom, Maxtor Diamond Max Plus 7200 RPM, Antec 400W PSU, Common Software Windows XP Pro w/all Windows Update patches, VIA 4in1 4.38(A), Intel Application Accelerator 2.0, NVIDIA Detonator XP 23.11, Software Setup Sysmark 2002, Internet Content Creation, Office Productivity, SiSoft Sandra Calculated Memory Bandwidth, SiSoft Sandra Theoretical Memory Bandwidth, Quake 3 Arena v1.30, Q3 Bench, 640x480 HQ Demo Four, 3D Mark 2001SE, PC Mark 2002, CPU Tests, The Test   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…. |
