480 Nitro...stock (vs 1350 MHz 480 reference/1060 2100 OC)

izgleda da je kao i kod nevidije, koja ima bolji cooler ;P
ALi ima neki bug u Wattmanu koji resetira postavke (potvrdjeno od AMDa), tako da testovi možda i nisu mjerodavni.

"If you have another Ł50 to spend then the
Sapphire RX 480 Nitro+ OC 8GB delivers better frame rates and we managed to get it stable to 1,390mhz in AMD’s Wattman. As I detailed earlier in the review I don’t feel Wattman is a great software package. Voltage increases didn’t seem to work on the Sapphire cards either so I am confident that when Sapphire release TriXX 3.0 better results will be possible.
We had to deal with another little glitch, also mentioned in our review of the Asus RX480 earlier this week. Target temperature settings would switch on start up from 65c to 75c, and then vice versa. Sapphire are aware of this issue and it has already been reported to AMD. We managed to test both cards at the correct setting of 75c and the fans are nonintrusive, with merely more than a faint whirr audible under load. In a similar fashion to leading cards from all the major manufacturers, the fans switch off at idle, and below a certain temperature threshold.
Right now the best RX 480 available is the Sapphire 8GB Nitro+ OC model. It is not only faster out of the box than the Asus RX 480 Strix OC model we reviewed earlier this week, but it is quieter and Ł40 less expensive. Below Ł250 makes more sense to me in today’s highly competitive market."
A i izgleda da bi trebali dobiti više voltaže iz durgih OC instrumenata nego iz Wattmana (Asus Strix review, Asus GPU Tweak)
"There is no doubt that there is some overclocking headroom available and that the Asus RX 480 Strix Gaming OC Aura outperforms the reference RX 480 we had in our labs for launch. Sadly we ran into a problem here as well. With AMD’s own, over complicated Wattman software, we were only able to increase the core to around 1,380mhz before instability would occur. We had more success with the ASUS GPU Tweak software, but were limited due to the sliders stopping at 1,400mhz. At this speed the core was completely stable, but there is potentially more headroom available."

razlika bi trebala otprilike biti kao i kod 380/380x 10-15%
