Remember it's AMD, and they're not the best at translating that raw compute into realized gaming performance. They're great, just not the best.

I also don't know why they are talking about 4K gaming on that hardware. It's not going to be any better than 4K/30fps. Who the hell will get excited about that? They simply translate today's 1080p (900p, 720p) complaints to 4K.

Now 1080p is going to be awesome on that, with console optimized games. I will give them that.

The problem is FLOPS is a stupid way of trying to compare hardware because you can get that number on any given task. It's like a HTIB claiming 1000 watts. Digital Foundry should stop doing it.

Also, it would be nice if AMD would just release the damn specs already.

XFX has already said they have a water cooled version coming out for $400.

I decided to read the fine print slide.
Quote:
Slide 31:Chart: Testing conducted by AMD Performance Labs as of June 10, 2016 on the Radeon RX 480 8GB on a test system comprising Intel i7-5960X 16GB DDR4-2666 RAM, GIgabyte X99-UD4, Radeon Software Crimson Edition 16.1.1, and Win 10 64-bit. Using the Steam VR Performance test, Radeon RX 480 score 6.3 and Radeon 380 scored 3.6. Performance may vary based on use of latest driver versions. Test results are not average and may vary. RX-2

Crimson 16.1.1? That's an old driver from February.

The test was done on June 10th as well, so the slide obviously isn't from the press event and no reputable websites are reporting this despite the slides saying the embargo ended on the 13th.

doh.gifsozo.gif whats the point on water cooling a low power GPU?
this card isn't even more power hungry than GTX960, yet they're gonna water cool it?
pointless waste of money, this could easily be cooled by a good air cooler.

One of the speculation is AMD went with power efficient with their ref design, and let the OC roof open for AIB. The AIB cards can be very hot and power hungry when the chip is stretched at its limit rolleyes.gif

It would be nice if the water cooled version can reach 1800 MHz and trade blows with custom 1070. I would care less about power consumption with my overkill 1200i PSU

Technically a XFX rep asked if people would be interested in a 390 that could swap between air and water cooling for $400, but he obviously wasn't talking about an actual 390.

RX480 will be a little faster than the 980 with twice the memory for half the cost. Can't see how that's anything other than a win for everybody.

This is yet to be seen, it's all speculation until we see actual numbers.

that doesn't mean it needs to be water cooled, even a 250W GPU when OCed to it's limits can be air cooled, let alone a sub 150W card.
this card doesn't even need 2x8PIN power, i can't see the point of water cooling such a low power card.

Molex pins are 6A each, at 12v that's 72w 12v per yellow wire, within safety if you consider 5A the technical reliable that means a 6pin PCIE lead is 180w per connector. A single 8 pin can pull the 250w including bus connect. Relying on the PCIE slot itself for more than 54w is dangerous. This is where we get the 225W 6pin PCIE spec.
