Cryptonight was supposed to be ASIC resistant algorithm but has turned out to be ASIC-friendly as there now more than three vendors support this algorithm. Below are the ASIC miners released until now-
Baikal Giant N miner consumes just 60W but hashes at 20KH per second!-

Antminer X3 hashes at 220KH per second but consumes 550W power - https://s9-antminer.com/product/antminer-x3-cryptonight-220kh-s/
Pinidea RR-200 27k/s(+-5%) - https://shop.pinidea.io/index.php/product/asic-cryptonight-miner-rr-200/
DragonMint X1 Miner 124kh/s - https://halongmining.com/shop/dragonmint-x1-miner/
The XMR devs seem to be at war with these vendors as they are changing their algorithm to cryptonightv7 and somebody has even made a counter here - http://xmr.noctism.com/. But it's said that these ASIC companies can overcome this change with a firmware update.
