I took the time to finally get xptMiner to compile with GCC for Windows.
It was a nightmare for me, but what does that mean for you?  Christmas may have come early.

I've compiled my optimized code for each of the following architectures: generic, core2, corei7, corei7-avx, k8, k8-sse3, and barcelona (k10).

The Windows x64 binaries are available from here:

Use whichever corresponds to your processor architecture.

If you're unsure, here's a quick guide based on your CPU manufacturer and age:
Intel: [Older] core2 -> corei7 -> corei7-avx [Newer]
AMD: [Older] k8 -> k8-sse3 -> barcelona (k10) [Newer]
Worst case scenario, use generic.


I will not be releasing any 32-bit builds.  "High performance 32-bit" is an oxymoron.


Let me know what sort of improvements you see!
Some builds may be slightly slower than the stock jh00 miner.  It all depends on your CPU.
