Linus tech tips did a reference 290 under water versus GTX 780 reference under water:
https://www.youtube.com/watch?v=RqaHh-y51us&feature=*********&a
GTX 780 reference: 4 phase PCB, GPU boost 2.0, 1.2V voltage limit
R9-290 reference: 6 phase PCB with AMD's boost, 1.25V voltage limit (?")
Net gain: GTX 780 gained 9% at maximum overclocks
Net gain: R9 -290 gained 7% at maximum water overclocks
GTX 780 @ 35C plus/minus a few at 100% GPU load. R9-290 @ ~45C+/- a few degrees @ 100% GPU load.. Gear used:
Koolance Gear
R9 290 Block: Koolance
GTX 780 Block: Koolance
Quick Disconnect Fittings: Koolance
Tube Reservoirs: Koolance
DDC Pump Top: Koolance
Maximum overclock with 24/7 stability in all games - core clock actual: GTX 780 ~1180MHz, R9-290 1110MHz under water per clock listing master spreadsheet:
