Assembled cognoscenti; just idle curiosity really. I am wondering about , causes of anomalous difference in execution time, same application (FreeDVDDecrypter), same OS (XP x64), different boxes ?
Box 1: Asus M4A79XTD_EVO; 16GB RAM;CPU AMD Phenom II x4 (4 core) 965 3.4GHz takes about 30min for 6GB DVD, with 1 core obviously flat-chat ~100%
Box 2: Asus_P6T-intel-i7; 20GB RAM; CPU Intel i7 (4 core) 940 2.93 GHz takes about 10min for same 6GB DVD, with no core seemingly particularly active
The Intel is using AES-NI whilst the AMD is not? Perhaps that's all there is to it; I think that is the most likely reason. AES is hardware supported with many (most) i7 and many i5 CPUs. Oh and if that XP boxen is connected to the Internet, be careful, be very careful. XP has no support and there are serious bugs that will never get fixed. Cheers A.
