Polaris 10, power hungry and doesn't clock.

Again, not true.

These people don't know what they're doing. Firstly, any voltage over 1.15 needs the power level increased beyond 150% to make use of the voltage increase. Secondly, they aren't going to make any gains ocing with the default bios. Not going to happen.

How did they add "large amounts" of voltage? Stock VDDC is 1.15v.

The 1060 cards that are $250 are miniature. the 1060 also has cards costing up to $330

Don't compare the cheapest 1060s to the more premium 480s pricing. Cheap 480s will come as well.

Did some basic overclocking this morning. (Sorry for the delay!) Got it up to 1405MHz core, 1850MHz memory, and +15 percent power limit. The extra boost didn't affect overall performance very much, though. You can see the results from some benchmarks and games here

Cheap 480's = reference. We know the prices there.

The cheapest 1060 will perform just like the expensive one. That's Pascal for you.

We didn’t expect to be able to push the Nitro+ RX 480 much further, considering its meager out-of-the-box overclock—but we wound up pleasantly surprised. Using the WattMan overclocking tools inside AMD’s Radeon Crimson control panel, we were able to boost the card’s power limit by 15 percent, its memory clock by an additional 100MHz, and its core clock all the way up to 1405MHz, which represents a 7.5 percent frequency increase over the Nitro+’s default 1306MHz max clock speed.

Doing so required cranking the fan speeds pretty high to avoid throttling. We set the max at 3,000 RPMs, which is definitely noticeable and definitely loud. Under load, they routinely spun at 2,800 RPMs or more, which helped keep the card running cool despite all the extra power coursing through its innards.

Now for the bad news: That epic (for Polaris) bump in clock speed still didn’t result in massive performance increases, though there were slight improvements in the games and benchmarks we tested. Seeing that, Sapphire’s decision to keep the clock speeds lower (and thus, also keep the card cooler, quieter, and drawing less power) seems rational.

Increase power level to 50%.. The card is power starved. It won't reflect clock speeds with out a boost in power. Also, use The Stilts embd mod. It can be found in the Rx 480 bios mod thread. It defaults power level to 165%. You won't see any gains without altering the power level%

Everyone thinks that just by moving sliders magic will happen... It's not that simple.

pcworld guys did increase power limit, but idk if that was the max


and this: http://www.overclock.net/t/1605648/guru3d-sapphire-radeon-rx-480-nitro/460#post_25370871

By default, the Sapphire Nitro+ RX 480 OC is already tuned to a fairly high maximum boost which limits the amount of headroom for manual overclocking somewhat. Unfortunately, Sapphire’s TriXX 3.0 utility isn’t quite ready and MSI Afterburner constantly causes stability problems when overclocking a wide range of AMD graphics cards. Therefore, I deployed AMD’s new overclocking tool, embedded in the Crimson driver and slowly made adjustments to the core and memory. Please note, the maximum power (50%) was applied as well as automatic voltage. This is because manually selecting the voltage didn’t appear to aid stability or reduce temperatures when selecting a lower value than the automatic configuration.

To easily outline the graphics card’s real world performance, I’ve included the average boost clock before and after manual overclocking. As you can see, the hefty factory overclock maintains a very stable 1342MHz boost and the core rarely drops from this figure. In contrast to this, the reference model had quite a sharp decline in its boost clock and behaved erratically. Thankfully, this doesn’t plague the Sapphire model and the improved cooling solution works wonders to prevent throttling.


Once overclocked, the boost clock hovers around 1360MHz, and a few slight drop offs bring the average down to 1359.8MHz. Please note, I did try to push the clock further and even added large amounts of voltage to no avail. As always, your mileage may vary but it’s important to remember that overclocking beyond the heavy factory overclock core is always going to yield small gains. On a more positive note, the memory overclocked by a decent amount and reached an average figure of 2126MHz. Before progressing, please disregard the extreme high fan speeds, which happened as a result of a bug discussed later in the review.

seems like maybe its true that with power limit at 50% ~1350-1360 is the best this card can do

but apparently Wattman only allows a max of 50%, so if you want more you will have to get creative .. thats not something most ppl wil do though I guess


and then there is the question of air cooling all that ..

It's the combination of voltage and clock speed that won't allow beyond 1350/1360, then the extra power level comes into play. I agree, though. Most people don't want to use other means. The Stilt's mod did wonders for my overclocking efforts.

Also, with pascal, the rx470 may be better than the 1060 in a couple years tongue.gif
