There is no ASIC h/w for mining XMR/Cryptonote coins. The only way to do so is via CPU/GPU. From GPUs I got the best performance with Nvidia cards on minergate's native miner (windows 8.1, 64bit) while on CPUs the absolute best miner is Claymore's miner (again on win8.1, 64bit). I'm getting about 200H/s on an i5 and about 400H/s up for an i7.
You can find Claymore's CPU miner here:
