RX480: Viable in 1440P?

With all the benchmark leaks Im starting to think the 470 can do 1440p no probs:

Here is the best thing however, the RX 470 manages to score the minimum VR spec across all the samples we came across. The minimum number we saw was in 13000 points range with overall P-Score around 12000 (which is the minimum VR spec in the 3D Mark 11 benchmark). On the last few runs however, the graphics figures shot as as 16000! Due to the fact that AMD has had time to refine drivers, we believe that the 16000 figure is a much more accurate representation of the performance the RX 470 will give when it finally hits the shelves.

Interesting... Is AMD holding back RX in drivers to keep nVidia on it's toes?

People are reporting 18600 3D Mark on 480 after driver upgrades...
 
Same article is speculating the SP count per CU is higher than 64 this time in GCN 4.0. It might explain the higher transistor budget estimated at 8 billion.

As you can see from the single card benchmarks, the RX 470 is on average 4000-5000 points behind the RX 480 which averages a graphics score of around 18000 (with P-Scores ranging around 14500 points). This is something that is quite expected, considering both have the Polaris 10 chip (with the RX 470 housing the cut version with slightly less SP cores). If we are looking at 64 SPs to a single CU ratio that AMD has used in the past then the RX 470 could have SPs in the 2048 range. Since the full Polaris 10 GPU has 36 CUs that would put the RX 480 at a cool 2304 SPs. However, there have been instances in the past where AMD has hinted that it might not be sticking with the 64 SP to 1 CU ratio this time around, so until the official numbers are out, the exact count remains suspect.

Wonder if anyone can take this 480 pict leak and do the transistor budget estimate out of it...

Hmm...this made me very intriguing. I've figured out that they've made beefy SP per CU, so this could explains why RX 470 can performs as fast as R9 290 level with only fewer SPs. I can't wait to see how much performance can RX 480 do!

Definitely by those benches the SP's are either a lot more efficient or we have lot more SP's that we expect from the GCN 4.0 CU unit. Either way we win! :)

Curiously, what card do you have right now? I have a 390X, but I think I'll keep it and might want to buy a 8GB RX 480. I'll probably move my 390X to my linux rig from main rig.

I have a 290 non x. Its plenty for this old phenom 2 965 rig but Im planning on building a new rig when zen comes out.
 
Last dx 9 game I was playing was indeed slow: WOT. But they recently updated to dx 11 and fps went up 2-3x lol.


I dont want to put a 480 in this rig obviously. But I also dont feel the need to go 4k. I think Id rather do 1080p HDR in a 32" mon with 4k vsr. Heck of a lot cheaper and probably a sweet spot for the 480. Samsung has a cool 1080p curved mon with freesync but its not HDR yet. But at 500$ is a killer deal. Its a 4ms VA panel. 4k is 2-3x that much.

Honestly Ive seen 4k and 1080p in a 32" and Im not sure 4k is worth it.
 
Oh ya but the fps increase from the previous 6950 was significant. I got the 290 on sale cheap. Current mobo wont take a 8000 class cpu... Most I could put in is a 1100t 6 core but I dont think its worth the upgrade over the 4 core 965.

I remember in some games like BF3 it was a nice increase over the 965.
