Still on 28nm, with a few more architectural tweaks compared to GM107. I had posted some detailed info and there was a good discussion on this a few pages back, check it out.
Do you have a source for this? Maybe I missed it but I don't remember them saying this publicly. I remember they had complained about increasing per transistor costs of advanced processes in general.
True..but since 16nm is based on 20nm..it should be easier than doing a full node shrink.
You have insider sources?
Will it be more like a year after the GM204 is released similar to the GK110 & GK104 or will it be shorter? I wonder if Nvidia is going to go 20nm or 16nm FF for GM200 or just have it on 28nm.
Maybe, but they are not using HMC ... they are using HBM, which unlike HMC has wide IO.
Yes, and they've proven to be right in the past so I have no reason to believe this isn't true.
Have not heard a definitive timeframe for GM200 yet but the gap should be less than that for GK104 to GK110. GM204/6 are targeted for release by Q4. From what I've been told, it is all on 28nm.
As stated above, if my information is correct then GM204/6 should be out by Q4. I have no idea about GM200 but I'd agree with you, it seems likely that it is a 2015 part.
I can't tell if you're joking but Maxwell and Pascal are two distinct families.
That's not necessarily what has been reported post GTC. NVIDIA are saying that Pascal is using the same SMM structure as Maxwell with the "Volta" architectural change (that would inevitably spawn a series of products) pushed off the roadmap slide but still slated post Pascal. Given those statements and "Pascal" really being a vehicle to stacked memory Blazkowicz's comment is one reasonable potential interpretation of the information.
That appears to be the case, and with Pascal shown as a 2016 part on the roadmap..it fits the 16nm process schedule as well.
From my understanding, compared to Maxwell, Pascal would have 3D memory, NV Link and Unified memory and is a completely different family. Even in the case of NI and SI, though they have less of a difference in features, I would still consider them a separate family. Either ways my point was that GM200 and GP200 are two separate chips.
They first had an exponential roadmap then they switched it to linear a year or so ago for some reason.
Scenario #1: GM2xx on 28 nm.

. But yeah I can see Nvidia going 16nm FF in 2016 with Pascal (maybe not take as long as performance range from GK104 to GM204) with something like a summer release for say a GP104. For what is going to likely be a 28nm GPU, GM204 is taking a while so I was wondering if the second generation Maxwell was going to be 20nm but then they switched to 28nm due to too much dimished returns or/and problems and had to go back change them.
There's no GK180, there's GK110 and "full respin" of it called GK110B
NVIDIA's Quadro Product Manager mentions that the K6000 has a GK180. It might be that GK180 = GK110B.
