Intel's Enemy No. 1: The AMD K6 CPU

How I've Tested

Common for all tests was the following configuration :

• 64 MB RAM
• Matrox Millennium 4 MB, BIOS 2.5
• Quantum Fireball 1280 for Windows 95 and DOS Tests
• Seagate Cheetah ST34501W at DPT PM2144UW plus RC4040 w/32 MB EDO RAM for Windows NT Tests

The K6 ran on different boards depending on the test configuration :

• Windows 95 (Build 950, Matrox Millennium Driver 3.41) and DOS Tests :
• Tyan S1570 Titan Turbo with 512 kB cache and 12ns Corsair SDRAM for 66 MHz bus speedAbit IT5H rev. 1.01 with 512 kB L2 cache and 50ns Micron EDO RAM for 75 MHz bus speedAOpen AP5T-2 with 512 kB L2 cache and 12ns Corsair SDRAM for 83 MHz bus speed
• Windows NT (Build 1381(Service Pack 2)., Matrox Millennium Driver 3.06) Tests :
• FIC PA-2011 with 1 MB L2 cache and 10ns Toshiba SDRAM for 66 MHz bus speedAOpen AP5T-2 with 512 kB L2 cache and 12ns Corsair SDRAM for 75 and 83 MHz bus speed

The Pentium MMX ran under the following conditions :

• Windows 95 (Build 950, Matrox Millennium Driver 3.41), Windows NT (Build 1381(Service Pack 2). Matrox Millennium Driver 3.06) and DOS Tests :
• Abit IT5H rev. 1.01 with 512 kB L2 cache and 50ns Micron EDO RAMfor 66 and 75 MHz bus speedAOpen AP5T-2 with 512 kB L2 cache and 12ns Corsair SDRAM for 83 MHz bus speed

The Pentium Pro (256 kB L2 cache) ran on

• Windows 95 (Build 950, Matrox Millennium Driver 3.41), Windows NT (Build 1381(Service Pack 2)., Matrox Millennium Driver 3.06) and DOS Tests :
• Asus P/I-P65UP5 plus C/P6ND with 50ns Micron EDO RAM

All CPUs were tested on the motherboards that offered best performance for the particular CPU.

Winstone and Winbench ran for each operation system under 1024x768x65536x75.
