To test all the CPUs listed in the table above we put together two similar platforms for Socket AM2 and LGA775 processors respectively. Below is the list of hardware and software components used for them:
- ASUS P5Q Pro (LGA775, Intel P45 Express, DDR2 SDRAM);
- Gigabyte MA790GP-DS4H (Socket AM2+, AMD 790GX + SB750, DDR2 SDRAM).
- Memory: GEIL GX24GB8500C5UDC (2 x 2GB, DDR2-800 SDRAM, 5-5-5-15).
- Graphics card: ATI Radeon HD 4890.
- HDD: Western Digital WD1500AHFD.
- OS: Microsoft Windows Vista x64 SP1.
- Intel Chipset Software Installation Utility 188.8.131.527;
- ATI Catalyst 9.4 Display Driver.
Although AMD Athlon X2 7850 and 7750 processors can work with DDR2-1067 memory, we tested them with DDR2-800 SDRAM, just like all the other testing participants. Our decision was mainly determined not that much by the desire to have all CPUs working in identical testing conditions, but mostly by economical reasons. Memory performance doesn’t affect the final system performance score that much that is why most users building a PC on a budget prefer to use more affordable rather than high-frequency memory.
