AMD: Speculation, Rumors, and Discussion (Archive)

$180 for the RX470 is still a spectacular value though, considering how close it is to the GTX 970 which was sold at almost twice that price not that many months ago.
The really small performance difference to the RX 480 shows that the P10 chip seems to be ROP/fillrate limited in most situations, even AotS.The only game showing a FPS delta that somehow corresponds to the compute throughput delta is Doom. id Tech 6 is really squeezing every last drop of GFLOP in all GPUs.

But the 970 is 2 years old and we should compare the prices of the 970 after the next gen launched. Overall I would say AMD should be happy that the 970 has many drawbacks and that NV has put it on EoL status.
 
I certainly would. If I got my favourite game from 20 to 30, heck, even from 30 to 40 Fps, I would gladly pay the 20$ extra.
I definitely would pay more for 30 to 40, but in the context of 470 vs 480, it is more like 10 to 15%, thus the 10fps is more like 60 to 70fps which personally I think the extra fps is not worth it.

Yes. In the present time the difference is not noticeable in most scenarios but the extra performance would give you more time before you have to upgrade your card. In my opinion is too close. I mean there is not a clear difference between segments aimed for this cards.

Well 470 review i have seen are custom models ( i think remember there will only be custom one ), clock speed are set a bit higher ( slighty ) this reduce a bit the difference between stock 480 and thoses one ( 3%-5% maybe ).

What i find funny is the 470 seems well seating in his 130W rate, i think AMD should have set the 480 at 170W with slighty higher clock and set the 470 as the low power budget reference . and specially launch them together. Peoples will have been a bit disapointed by the "TDP" of the 480, but the 470 will have been there for take the hit on this front.
 
The differentiation makes no sense at all. The custom versions of the 470 are too close to the 480s in performance and power consumption, while both are offered with 4 or 8GB.

Imho it would have made sense to have the RX480 with 8GB only and a TDP of around 175W for the reference, with the R470 at 130W and with 4GB only.

That totally depends on the game you're playing, in which resolution and the level of details as well as antialiasing-settings you're applying. But I agree, when talking about the 60-70 fps range, I don't see much benefit there either.

We've received the Sapphire Nitro in the meantime and out of the box it seems like it's a wholly different card compared to what Asus did with the 470 Strix.
 
Agreed, keeping that name with little to no preparation was a rather... not-so-well-thought-out move.
 
Some gurus reviews of 470 are up..

Powercolor Red Devil. 470 4GB .. Here the difference with the 480 is even less ... 2-3 fps in average, with even some games at 1fps under .

The card is slighty tweaked with 7000mhz memory and 1270mhz on core ( that i suspect run mostly at ), seeing the poor difference with the 480.

Its a bit typical, If we compare with the 480 stock version, thoses custom 470 run at their max turbo clock speed nearly all the time due to their custom cooler and more margin on the TDP, the stock 480 had a lot of clock variation, and was run under his stock boost speed in many games. So in reality even if you see both cards with same clock speed, thoses custom 470, in usage, are running at an higher clock speed than the reference 480 who kill the small difference of SP count.

Interesting find, when pairing a low end, mid range CPU or older CPU with the rx480 and Vulkan, there is more CPU overhead, similar overhead to DX11 and Ogl. Would be interesting to see more tests on this.

36 CUs confirmed. The GDDR5 PHYs are pretty big (~30mm²), the 256-bit interface on Tonga "only" takes ~24mm². The 8Gbs definitely take their toll here. For comparison, one 1024-bit PHY on Fiji needs 10mm². Major potential for Vega to make energy and area efficiency gains on the memory side.

the 470 is about right for a micro itx i'm building for my little cousin. The 970 uses way to much power , more than the 480 actually
