Testbed and Methods
We tested the performance of AMD Athlon 64 X2 3800+ and compared it against the results shown by the processors falling into the same price category. Among them are: Athlon 64 3800+ ($373), Pentium 4 650 ($401) and Pentium D 830 ($316).
So, we assembled a few systems with the following hardware components:
- AMD Athlon 64 X2 3800+ (Socket 939, 2.0GHz, 2 x 512KB L2, E4 core revision aka Manchester);
- AMD Athlon 64 3800+ (Socket 939, 2.4GHz, 512KB L2, E3 core revision aka Venice);
- Intel Pentium D 830 (LGA775, 3.0GHz, 2 x 1MB L2);
- Intel Pentium 4 650 (LGA775, 3.4GHz, 2MB L2).
- ASUS P5WD2 Premium (LGA775, Intel 955X);
- DFI NF4 Ultra-D (Socket 939, NVIDIA nForce4 Ultra).
- 1024MB DDR400 SDRAM (Corsair CMX512-3200XLPRO, 2 x 512MB, 2-2-2-10);
- 1024MB DDR2-667 SDRAM (Corsair CM2X512A-5400UL, 2 x 512MB, 4-4-4-14).
- Graphics card: PowerColor RADEON X850 XT (PCI-E x16).
- Storage subsystem: Maxtor MaXLine III 250GB (SATA150).
- Operating system:
- Microsoft Windows XP Professional SP2;
- Microsoft Windows XP Professional x64 Edition.
The peculiarity of our today’s test session is the use of two different operating systems: 32-bit and 64-bit Windows XP versions. When we tested the processors in 64-bit mode we tried to use mostly native 64-bit applications, which have already become quite numerous by now. This way we will be able to evaluate the processors performance and efficiency not only in 32-bit mode but also in case AMD64 and EMT64 technologies kick in.
To be fair we should definitely mention that many 64-bit applications available today are none other but Open Source program ported developed by computer enthusiasts. So, these programs boast very unique specifics. Unfortunately, there are very few really 64-bit versions of any large commercial products from big-name companies.
