AMD "Ellesmere" ASIC Pictured Up Close in RX 480 PCB Picture Leak
AMD's all-important Polaris10 "Ellesmere" ASIC is pictured up close in a 3-quarter PCB shot of the upcoming Radeon RX 480 / RX 470. The picture reveals the ASIC with a die that's significantly smaller than that of the 28 nm "Tonga" silicon. The "Ellesmere" die is built on the 14 nm FinFET+ process. The die is seated on a substrate with a 256-bit wide GDDR5 memory interface. This appears to be a common reference PCB between the RX 480 and the RX 470.
The RX 480 ships with a classy looking lateral-flow cooler that's longer than the PCB itself; while the RX 470 uses a more common fin-stack top-flow cooling solution. Of course both cards are expected to ship with custom-design boards and cooling solutions. The reference PCB draws power from a single 6-pin PCIe power connector, and uses a 6-phase VRM to condition it for the GPU and memory. Display outputs include three DisplayPort 1.4 and one HDMI 2.0a connectors. There are also unused traces on the PCB for a DVI connector, so it's likely that some custom-design cards could feature it.

But they won't take the enthusiast top spot (GTX 1080).
Sooooooooooooooooooo yeah.
Maybe Radeon Pro would be Top Spot but with occasional profile absences, the average would possibly drag it below GTX 1080.
and nothing to do with performance?
You can do with that as you wish, I pointed out an alternate and if you cannot accept that there are other top spots then in performance... (like sales, overclocking, price/performance, power consumption(/performance), etc) well I cannot help you any further Im afraid.
GTX 1080 is also broken in DX12.
GTX 1080 despite being 16nm and clocked at 1.6gHz BARELY outperforms Radeon Fury X in AOTS benchmarks.
You may recall that Fury X is clocked at 1.05gHz and is last years Radeon top tier with 28nm process.
GTX 1080 should have bested Fury X by 20-30% in clock speed alone but failed miserably.
As I said nViida gpu's are broken running DX12 games.
And nVidia just announced that 3-4 way SLI will no longer be supported.
And anyone with half a brain would know that IPC != clockspeed. You cant compare clock to clock directly unless the GPUs are the same arch.
And nvidia's GPUs are far from broken in DX12. They dont do async compute, but they are not broken.
I swear, this generation of GPUs has brought out some real nutcases in the forums.
People are constantly talking about sales, how much something has sold, how much it will sale, how good that will be for the company, how much its needed, market share, just constantly sooo yeah.
