I really hope AIB RX480's can hit 1400 with ease.
I wouldn't go as far as say with ease, but it'd' be a much closer battle than it is now. Remember that 1060s can OC into the 2100 range, not just 1800.

I'm seeing a lot of the AIB cards come with 1330. I'm hoping as well, that 1400 is the average. That would mean great competition between the two in DX11, though i'd still expect the 1060 to edge it out.

Hm. So I just discovered that the RX 480 actually loses performance under DX12 in Rise of the Tomb Raider... In a similar fashion to nVidia. I wonder why.

Hopefully, this will not be a DX12 trend...

Not bad at all, isn't that a gimpworks title? I thought the difference would be around 10fps not just 0-5fps.

I am waiting for custom RX 480s but my patience certainly grows shorter by the day with AMD and it's board partners.

Tomb Raider DX12 is broken, don't use it, the devs still didn't learn it enough to get better than DX11 performance where in DX11 the driver corrects their mistakes and doesn't allow them to mess up as much either.

That's odd, I haven't seen any mention of that before you mentioned it. Interesting though. Are you sure those aren't minimum frames?

Ya but it is also often an equal amount above 1200MHz, so it is pretty safe to call an even 1200 the average. You cant disclaimer scores with adding stuff like: (1174MHz 4%, 1180MHz 6%, 1194MHz 18%, 1200MHz 20%, 1202MHz 14%, 1204MHz 19%, 1209MHz 3%, etc etc etc) to try and show how long it was at a specific MHz. 99% of people will be happy if they just say "1200MHz".

I've already shown this table from computerbase in this thread..

The 480 averages at 1190 across all titles, in TW3 it's less than that. 1200 is not the average in TW3.

That sounds very fair and realistic. Thank you.

It fluctuates between 1180-1200 MHz. 1190 MHz would be pretty fair and reasonable as an average.

So let's throw out the 1200 MHz that the maker of the charts saw in his test and use the ones you want.

So we now have a 19% overclock giving 24% and 28% more fps.

So no, it's not throttling on the reference card that can explain the numbers.

I will just throw this in here for everyone to ponder.

GTX 1060 - 200mm^2 - 130W - 4.4B transistors
RX 480 - 232mm^2 - 150W - 5.7B transistors

Difference in area 232/200 = 16%
Difference in power 150/130 = 16%
Difference in transistors 5.7/4.4 = 30%

Power per 1B transistors:
GTX 1060 - 29.55W
RX 480 - 26.32W

Area wise 480 has higher power consumption in line with the increase in area. Transistor count vs power 480 does better because it has higher transistor density and lower overall power consumption for the amount of transistors it has.

The issue with AMD lies in the GPUs not being properly utilized by applications which limits and even hurts their performance, also some of the area/transistors are used on features that do not translate into FPS (computing) but rather offer flexibility and parallelism (managing). On paper otherwise AMD does better, just not always in current games and apps.

I'm guessing there's a VRAM OC as well, Polaris likes having that extra bandwidth and VRAM on most cards hits 2200mhz easily enough
