Sapphire Radeon RX 480 Nitro 4GB and 8GB OC

[cheesemp]

Well my 480 8gb has just turned up (I cancelled my preorder at overclockers as they had no stock and went for one at ebuyer). Can't wait to try it out tonight!

Well quick feedback in case anyone is interested. Plugged it in and I'm getting 2 to 5 % less on benchmarks than Tarinder did. Not sure if its my older system holding it back or something else. It seems to stick at boost clock and 75C so its not temperature limiting it. Nice card though and I never heard the fans until I forced them to high speed in wattman. Did manage to crash wattman twice though and I didn't even and try and do that much. Hoping it improves or the Sapphire Trixx software is released soon as a memory overclock seems well worth doing.

Cool! Are you comparing total system benchmarks or just GPU benchmarks? Look up the 3dmark time spy graphics score and see how you compare - you should be within a few % even on an old system.

Just Firestrike and Timespy at 1080p. I get about 10400ish (I can't remember exact figure - Tarinder got 1000 more) and just over 4000 (I think it was basically the same as the 390 - Tarinder got 4361) on timespy. Looking at figures its closer to 10% slower. That just can't be right can it? The system isn't very clean as its windows 8 upgrade to Windows 10 and had Nvidia drivers on before (I did run DDU to clean the nvidia drivers off). Maybe its time for a reformat?

Possibly a reformat might help. It is Windows after all.

Are you just looking at the total scores or the GPU scores?

Ahhh. Didn't know the number was combined. I will rerun tonight and see if I'm worrying about nothing!

On Timespy you should get a graphics (not total) score of between 3800 (reference card) and 4300 (nitro with slight overclock). I'd guess around 4200.

Both out of the box scores with the Nitro+ OC 8GB. In graphics test 1 of Firestrike it definitely wasn't holding 1342 but I didn't see it drop below 1280, so it's faster than reference assuming the reference can hold its boost.

With +50% power target it held 1342 without any problems, combined with a very slight nudge to the memory (+50MHz) it gave this Firestrike - http://www.3dmark.com/3dm/13815364?

Thanks Bagnaj97 - My 3dmark graphics scores are near identical - 13633 vs your 13564 in firestrike so I guess nothing to worry about. I'll try playing with the power target later as my PSU has plenty of capacity. Hopefully I can get similar results to you...

Edit: 13857 with 50% extra power limit and 50 extra Mhz on the memory - again similar to you.

The performance is insane for the price point but not only that, I think to have an 8gb option on a card at this price point is phenominal!

A lot of the time, you see extra memory on mid range gpu's and it's just pointless, a waste of space and resources as the performance of the card doesn't justify the extra memory. But this! Especially in crossfire!
