right, Hawaii is the most amazing GPU they've ever made, easily go 1200/1600mhz, ~25% performance increase for 25% clock increase

Some truth in that, a shrink would probably have been a good way to test out the new node and Glofo/Samsung fabrication.

Polaris was made for the low power/mobile market. High clocks loose the efficiency it was designed for, like in the 480.

The 460/470 will hit that 2.7x perf/Watt figure.

A few of the people who've slapped on custom coolers are getting over 1400 MHz on these reference boards.

A decent PCB version with good power delivery and cooling might work wonders for this chip.

Exactly, which is why I'm choosing to believe that Kyle was not lying when he said AIBs are seeing anywhere between 1480-1600mhz on the chips.

What reason would he have to lie........

Plus these numbers would fall into line with pre release rumours of them matching fury X once overclocked to the max.

I got the 480 4gb yesterday. After some tests i will send it back because the reference cooler is bad

I found a lot of reasons why this card can't overclock.

Cooler. Even on stock is throttling heavily. I dont know why not all reviews said about this problem. They dont even check their stats?
Vrm temps. Its over 70 all the time. A big limit on the overclock just there
1 6 -pin

I will wait for a proper AIB version. First time that i got a bad reference from AMD. The pcb is fine but the cooler and the 1-6pin really limits what this card can do.

On the positives, the card can undervolt really well like i can save 0.1V and still maintain the stock clocks while saving 20-30 watt.

Well i have to go to work now . If i have time tonight before i send this card back i will upload some tests

Yeah. I will wait for AIB cards to see what they can do before buying one.
