Re: 64bit CPU on linux
AMD64 is better than intel's
Yes it is, and do you know why
Because AMD64 is not only a 64 bit processor, but unlike the Intel IA-64 architecture it does also support 32-bit processing.
Thus in AMD you get the best bet, you and keep your current software and install new 64-bit software.
but my question is that all EDA s/w will support 64 bit
Of course not, because all present software is for 32-bit architectures, and you will need to redesign the software or better if the software manufacturer already supports 64-bit processing.
But in AMD64 you can use EDA software, since it also has 32-bit emulation.
The answer is simple, EDA tools (especially spice) rely on FPU performance hence AMD will allways perform better regardless.
I have to strongly disagree. AMD processors right from the K5 to the AMD Athlon (pre AthlonXP processor), suffered from an inferior FPU unit, Intel processors where always better, thats why all the heavy games like Quake3, Unreal Tournament, where for intel processors,
If AMD would have better FPU performance, than their would have been no reason to not support AMD processors, by all major Game Manufacturers.
Any way AthlonXP has a better FPU performance on a per-MHz basis, because it has a higher amount of cache than the Intel P4, thats why it can carry out bigger chunk of instruction in a single unit of time, whereas the P4 would take multiple cycles to do the same.
