AMD Radeon R9 Nano

If this turns out to be true, this is just jaw dropping.

unrealistic specs. The Fury is likely to be around 3584 sp and 1 Ghz clocks which puts it around 7.1 TFLOPS. AMD is looking for Nano to compete very well with GTX 980 both in terms of raw performance and perf/watt. With all the architectural enhancements of Fiji and the massive bandwidth of HBM a 3072 -3328 sp chip at 850-925 Mhz can easily achieve a 10-15% higher performance over GTX 980 easily. It can do this at 175W. I don't see a need for any higher specs/clocks. Incidentally 925 Mhz is the clock speed of the HD 7970 and it was a much better perf/watt card than R9 280X which had to bump up voltages and sacrifice perf/watt. My guess as I already said is - 3072 sp , 925 Mhz, 64 ROP, 4 GB HBM.

btw R9 290X is not a 250W TDP card no matter whoever says it. I would say realistically its a 260-270w TDP card. If we take R9 290X TDP as 270w then Nano has 65% of the R9 290X TDP. Assuming the perf /watt is 2x as they claim.

Perf /watt = x / 0.65 = 2x . That means x = 2x * 0.65 = 1.3x . 30% faster than R9 290X. roughly 12-15% faster than GTX 980 which is roughly in line with Captain Jack simple leaks 6 months back.

It would take the fastest factory clocked GTX 980 cards EVGA GTX 980 Hybrid to match R9 Nano but they would be well past 175W TDP by that time and requiring expensive cooling.

R9 Nano is the most exciting product of the Fiji lineup as given the monster die size of Fiji (596 sq mm) and the fact that the highest volume SKUs on such monster chips are always the most deeply salvaged SKUs and the likely pricing of R9 Nano at USD 429 - 449 it has the greatest impact on AMD's sales and also the biggest threat to Nvidia. R9 Nano brings GTX 980+ class perf to a form factor and power range which is undoable for Nvidia without HBM. Not to forget the pricing on R9 Nano will be a killer at USD 429- 449. R9 390X is priced at USD 429 for the time being to fleece the uninformed few. R9 390X will move down in price to USD 349 - USD 379 by late Aug or early Sep when R9 Nano launches. Most people who know their tech stuff will wait for R9 Nano and get it. No product in the next 12 months can provide that kind of performance in that TDP and form factor. :whiste:

I think those specs on WCCF are not that unrealistic. AMD guys even stated that it will be around performance of Fury X, depending on thermal environment.

So were not talking about GTX980+ performance. Much higher than that.

Also I would literally read the AMD Slide about Fiji: One Chip, Limitless Innovation .

This sounds very plausible...
