32-Bit VS 64-Bit Performance Benchmark
August 19th, 2007 / No Comments » / by Faizan
Now a days most of Desktop computers have capability to do 64-Bit processing. As 64-Bit computers and operating systems are around for a while but most of home users still use 32-bit OS on their 64-bit machines. The reason for this can be less availability of 64-bit drivers for old hardware, and most of current 64-bit softwares does not give enough performance boost over their 32-bit versions.
Back in january 2006, I got got my first 64-bit system. In order to check how much current 64-bit application gives performance boost over 32 bit-applications I have done a lot of benchmarking on my system. As I’ve both 32-bit and 64-bit versions of Matlab for both Windows and linux so I choosed it to benchmark my system for both 32-bit & 64-bit Windows & Linux.
- AMD Athlon64 3200+ (Winchester)
- MSI K8N NEO4 Platinum
- Nvidia Geforce 7600GS 256MB
- 1 GB Corsair Value Ram (2.5-3-3-8)
- WD 250GB SATA II 16MB Buffer
- Sony DRU-830A Dvd Burner
- LU LAPACK. Floating point, regular memory access.
- FFT Fast Fourier Transform. Floating point, irregular memory access.
- ODE Ordinary diff. eqn. Data structures and M-files.
- Sparse Solve sparse system. Mixed integer and floating point.
- 2-D plot(fft(eye)). 2-D line drawing graphics.
- 3-D MathWorks logo. 3-D animated OpenGL graphics.
