http://www.xbitlabs.com/articles/cpu/display/x86-64-rc1_9.html The obtained results are very curious. While Pentium 4 processor with EM64T support benefits from the shift to 64-bit mode in almost every benchmark, the competitor from AMD is very often getting fewer points in 64-bit OS compared with its results in 32-bit operating system. However, I would like to assure you right away that this result is not indicating any overall performance drop of Athlon 64 based systems in 64-bit work mode. The problem actually lies with the SiSoft Sandra 2005 SP1 benchmark, which is better optimized for Intel EM64T architecture. Our analysis shows that SiSoftware uses an Intel compiler to form the execution code for its benchmarks :khong: . Moreover, 32-bit and 64-bit benchmark versions use different algorithms based on unequa instructions sets. Therefore, you shouldn’t base your verdict on the results of only this particular benchmark.
Phần lớn ứng dụng P4 64 bit chạy đều thua khi chạy trên win 32 bit mà điểm sisoft lại cao hơn :xicawe: =====> cheat xiềng :laloi:
móa thằng Intel giàu quá nó bỏ tiền ra cho mấy thằng viết softwares optimize cho nó. nếu mấy thằng viết software không optimize cho ai hết không biết Intel nó nằm ở góc nào ? ặc ặc .
