Testbed and Methods
We split the testing of our system based on AOpen i975Xa-YDG mainboard and Intel Core Duo T2600 processor into two parts. First we wanted to compare the performance of our AOpen i975Xa-YDG mainboard against that of the Socket 479 ASUS N4L-VM DH mainboard, which we have tested before. This comparison promised to be especially interesting because these two mainboards are based on two different chipsets: the desktop i975X and the mobile i945GM respectively.
The second part of our test session was devoted to the performance of Intel Core Duo T2600 processor when we overclocked it to 3.0GHz. The previous test session performed at nominal frequencies showed that Core Duo was a pretty competitive solution in the desktop segment. Now that we managed to get it to work at 40% higher speed we might be able to make new much more interesting conclusions.
Our testbeds were built using the following equipment:
- AMD Athlon 64 FX-60 (Socket 939, 2.6GHz, 2x1MB L2);
- AMD Athlon 64 X2 4800+ (Socket 939, 2.4GHz, 2x1MB L2);
- Intel Core Duo T2600 (Socket 479, 2.16GHz, 2MB L2);
- Intel Pentium Extreme Edition 965 (LGA775, 3.76GHz, 2x2MB L2).
- Intel Pentium D 960 (LGA775, 3.6GHz, 2x2MB L2).
- ASUS P5WD2-E Premium (LGA775, Intel 975X Express);
- ASUS N4L-VM DH (Socket 479, Intel 945GM);
- AOpen i975Xa-YDG (Socket 479, Intel 975X Express);
- DFI LANParty UT CFX3200-DR (Socket 939, ATI CrossFire CFX3200).
- 2048MB DDR400 SDRAM (Corsair CMX1024-3500LLPRO, 2 x 1024 MB, 2-3-2-10);
- 2048MB DDR2-667 SDRAM (Corsair CM2X1024-6400PRO, 2 x 1024 MB, 4-4-4-12).
- Graphics card: PowerColor X1900 XTX 512MB (PCI-E x16).
- HDD: Maxtor MaXLine III 250GB (SATA150).
- OS: Microsoft Windows XP SP2 with DirectX 9.0c.
We tested the platforms with the mainboard BIOS setup for maximum performance.
Note that when we overclocked the Intel Core Duo T2600 processor to 3.0GHz by raising the FSB frequency to 231MHz, the DDR2 SDRAM frequency inevitable went up, too. Therefore, when we tested a system with the overclocked processor the memory worked at 770MHz. The timings remained at 4-4-4-12.
