only socket A semprons are k7s. from AMD's site the 3300+ socket 754 is stepping D0, E3 or E6.
the E3/E6 is a 64-bit Palermo core with mmx/sse2/3dnow! with a 16bit 800Mhz HT link. the D0 is the same but might (!) not support 64bit and the cache sizes are half as bug. (64/128 vs. 128/256). - erik http://www.amdcompare.com/us-en/desktop/Default.aspx http://www.cpu-world.com/CPUs/K7/index.html http://www.cpu-world.com/CPUs/K8/TYPE-Sempron%2064.html
