In ROP limited situations, an AIB RX 470 with higher clocks than 1266 will outperform a reference RX 480. In shader bound situations the RX 480 will be about 10% faster. None of this is rocket science, its pretty simple to extrapolate the performance from the number active units on the chip.

News of the RX 480 4gb reference card being discontinued is pretty old now, the fact that they are actually 8gb cards with a firmware memory limitation pretty much confirms this. Why sell a card for $40 less than its value if you dont have to anymore?
No, 470 will not be faster than 480, despite both of them have the same number of rops. 480 has faster vram and that is the end of it. However, 480 won't outperform 470 in shader bound situations because they both are limited by rops to make use of available TMUs. It would require 48 rops to fully benefit an Ellesmere gpu, 42 rops in the case of 470. Therefore, they would rather be as equals in that case instead of the rop bound one, stated before.

I hope there is an 8GB version of the Sapphire Platinum Edition. 3+1+1 phase arrangement is what every 480 should have been.

480 isn't over 300 unless that is all you're looking for.

This line of thinking is hilarious. I had 3 480s in my cart between amazon, newegg and best buy today, all between $240 and $250.

Also, anyone who keeps beating the "out of stock for weeks" drum is full of it and has no actual interest in making a purchase.

We saw much of the same with 290/290X with custom 290 cards matching reference 290X cards in performance. The difference is so small that a high end AIB 470 will match or exceed the stock "reference" RX 480 in some games. Overall the difference seems to be +2% to -10% with the average in the -3% range.

Oh look, if you OC the 8gb MSI RX 470 it beats the 8gb RX 480 reference...

Digital Foundry:

So this card is practically 970 with better perf/watt


*EDIT: It's actually faster than 970 if you combine DX11 and DX12 performance (and this is w/o DOOM Vulkan):



Only 5% slower in DX11, while in DX12 it leaves 970 far behind. Faster even in Tomb Raider

It depends on the Wattman(PowerTune) TDP target and the switch between the render methods of Directx 11/12, imo. There is no way to make use of the 50 idled TMUs of 480 without adding the missing 33% of rops.

The 4GB RAM in the 470s are actually rated for 6Ghz.

According to Tom's hardware, the RAM in ASUS's 470 is same as the ones in 390s, which is the https://www.skhynix.com/products.view.do?vseq=953&cseq=81

It has a WCK of 3Ghz, which is 6Ghz effective.

So the AIBs already overclocked it by 10%.


Conclusion: Don't expect your 4GB to OC to 8Ghz unless you are lucky.


Also, neither Samsung, Hynix, nor Micron make 6.6Ghz GDDR5. It's either 6, 7, or 8Ghz.

Pricing is ridiculous, now is to wait 1050 to kill this card. AMD is back to their overpricing style like how they did to 300 series. Inferior higher power consumption product but without better price/performance to justify it. lol

It is nvidia all the way.

Wouldn't it be crazy if the 1050 came out 10% under 1060 @ $200

I dont know if its just this model, but their monitor department seem to share the same lack of quality control as well. Sapphire all the way for me. Dont know whats the bigger story. The price/performance of the 470 or the vaporware that is the actual card on the ground.
