3.2C and 3.2E

[jett]

is there a big difference between the

Intel Pentium 4/ 3.2C GHz 800MHz FSB, 512K Cache, Hyper Threading Technology

and the

Intel Pentium 4/ 3.2E GHz 800MHz FSB, 1MB L2 Cache, Hyper Threading Technology

thanks

3.2C = Northwood core, faster, cooler
3.2E = Prescott core, slower, hotter

But the 3.2E with the Prescott core is newer, cheaper for Intel to make, and it's one performance advantage is it has SSE3 instructions, where the Northwood only has SSE2, otherwise the 3.2C is the faster CPU faster.

what are sse3 and sse2 instructinos

 

[Lazn_Work]

SSE = Streaming SIMD Extensions

SSE2 and SSE3 are enhancements/additions to SSE

They are really all enhancements to MMX (from way back)

All this really means is that they are special additional instuctions for mulitmedia, games, encoding and other Floating Point intensive tasks. (complex math type of stuff)

Programs do have to be written specifically to use these instructions, but if they know about them, they can use these faster ways of accomplishing their tasks.

3.2c and overclock the piss outta it! ehhehe

The Prescott should scale better, but on air cooling, you probably couldn't clock high enough to see a difference.
