GTX 1060 is less power hungry
post #462 of 860
This is pathetic on AMD's part, they really dropped the ball again.

RX 480 has been out for 3 weeks....reference only still with ZERO communication regarding release of the AIB cards.

The 1060 released with reference AND AIB cards 3 weeks later, slightly beating the RX 480, with a better price to performance and from what I can tell, better availability. Some AIB 1060's costing $249 vs the RX 480 reference 8gb for $239. If you have no allegiance to any particular team it's pretty clear which card to choose from.

Now from what we can tell, the RX 480 AIB cards are going to price themselves too high compared to its competition.

This is some real head-scratching stuff from AMD and it's one of many reasons why Nvidia fans poke fun.

AMD, I want to support you, I genuinely do....but you make it really hard sometimes.

Overclocking and Overclocked Performance

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.

Here we can see the default boost mode clocks and the enhancements I managed using AMD’s WattMan software.

After the overclock was applied, the Sapphire Nitro+ RX 480 OC defeated the MSI GTX 1060 Gaming X running at stock settings. While it’s still some way behind an overclocked GTX 1060, the synthetic scores are good and showcases the benefits of overclocking.

looks like those 1340-1370 clocks on the Strix were no fluke and these AIB cards so far cant get to stable 1400 for some reason

Sapphire Nitro will be available next week... Although 2000 units of one retailer are already sold out in the UK due to pre-orders....

IMHO they won't, it's been the same with the same chips on reference model, a PCB redesign won't change the chip's capabilities lol
Polaris 10, power hungry and doesn't clock.

Not true...;

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.
http://www.itworld.com/article/3098825/components-graphics/sapphire-nitro-rx-480-review-polaris-rethought-and-refined.html?page=9

On the flip-side, they did not see practically any performance increase while pushing the clocks further....

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.

Overclocking this card to actually gain performance from it is apparently more complicated than increasing voltage and frequency.

because without increasing powerlimit there will be no overclock gain...

Remember 1266 is the default boost, and there is no voltage control yet outside of the modded asus bios I believe.
