PCWorld got to 1405 MHz but didn't receive a significant performance boost anyway...

Temperature
custom 1060: 63C
custom 480 OC: 75C

Even my damn 280x did 70-75C. They show even a damn Sapphire 390x Tri-X at 68C. So WTH Sapphire.

Blackops_2: yeah I know, I think the card was throttled on power or something, I would have to read it again. And they left out 1060 from some of it's charts, one has to open a 1060 review side by side when reading it.


You can push GTX 1060 for 10% more and you will get 50% more power.
But I dont get where did they got 100W more? and HOW?

Was it with Mem OC? Because the 4GB only has 1750MHz while you can OC the 8GB to 2200MHz or even 2250MHz and iirc Mem OC with Polaris gives you a decent performance boost.

Memory was increased by 100 MHz, so it was still slightly slower than stock 8GB.

BUT, if that is true, this means the GPU is actually bandwidth limited... You have to have more memory bandwidth to get more out of the GPU... So the Polaris GPU actually has more performance potential at those clocks than can be extracted from it with the current GPU setup.

Will we see the RX 485 with more memory bandwidth to improve the GPU's performance...?

the power consumption of RX480 is from the contributions of power saving features.
overclocking may have caused this feature to have less of an effect, hence a drastic power consumption increase.

e.g. at low clock and low voltage, the card is forced to power throttle in a nanosecond scale, thus reducing power consumption.
at a high clock and high voltage however, the card's power throttling is hindered, thus drastically increasing power consumption.

Dunno How ! Nano is 28nm, RX 480 is 14nm but here

 

http://www.eteknix.com/sapphire-nitro-rx-480-oc-8gb-graphics-card-review/11/

 

Nano = 267w vs RX 480 = 302w

 

What the hell is going on ?

Mostly out of stock in North America if you want to pay MSRP.


Edit: There seem to be plenty of stock in Asia too.
Well they're selling them for 300+€ here. Though Germany and the UK seem to have more reasonable prices.

I wonder why the gains in clock speed aren't really translating to much performance?

Because they're not overclocking it correctly. Anything over 1360mhz needs a boost in power level to compensate. 50% won't show gains at those speeds. Alternately, anything over 1.15v also needs a boost in power level%

To get optimal performance with my card at 1405/2200 (1.2v and .975v respectively) I needed 160%. At 1.25v and 1425 it required 165%.

Well RX 480 silent mode looks quiet efficient.
