What does the water cooling say to you?
As I've seen water-cooled sku's for years now. So it only says to me they'll also have a water cooled version so it can be pushed further.

I've seen the TU102 board with 3*8pin.
I'm pretty sure there's watercooled 1070s.
It's a question of product being >$400 MSRP over anything else.
And I have seen TU102 board with 3 x 8-pin PCIe power connectors
Last Toxic-series models I know of having watercooling were with 135 and 210 W TDPs, that doesn't actually speak anything for itself.
yes, TU102 and NAVI are very comparable performance wise . LoL
You missed the point (I'm pretty sure @Bondrewd had same point as me) - TU102 ES was 3x8, that doesn't mean retail needs it. Just like Navi ES was 2x8 doesn't mean retail needs it
yes. Vega 10 clocked below 1200MHz can be efficient too ...

That's some exceptional goalpost moving, but that doesn't change TU102 ES being a 525W housefire.

AFAIK it's the first time Sapphire will be offering a custom WC card. So far they've only launched graphics cards with reference waterblocks (Fury X and Vega 64 LC).
It could go either way, really.

Wait... is he saying Navi will have maximum 5 CU per SE? Or is he talking about the specific case of the 40 CU navi announced for PC?
I´m hearing all kind of things, from navi beeing able to reach 128 CUs keeping each SE with 16 CUs, to Navi having cutted in Half the number of CUs per SE. This last one would mean the bellow scheme:
Wich one is it? I´m inclined to the last one, keeping maximum CUs at 64.

Probably just the particular SKU. It sounds like it'd be a 4x Kaio Ken Pitcairn.
I'm not sure what to make of the 32 wavefront per CU compared to current GCN. Currently, we're at 10 wavefronts per SIMD (40 per CU) unless the terminology is garbled.

Is it safe to deduce that the next generation will be akin to Pitcairn in Super-Saiyan mode?
Nope, they've had watercooled Toxic-cards before, X1900 XTX and HD 2900 XT

On current GCN a wavefront is a total of 64 threads.
Each SIMD can hold up to 10 Wavefronts... That's 640 threads per SIMD, and with 16 CU you get 40 per CU. A 64 CU GPU would get a total of 2560 Threads
Now... with a wavefront of 32 that must be diferent! Although I doubt final values are diferent.
So if I reverse calculations, for a 64 CU Navi I would get the same 40 per CU, Diference would be that the SIMD would get 20 wavefronts.
Not shure this is correct, or even possible, but I doubt total capacity has been reduced.

I just looked up those GPUs and they make absolutely no sense, lol.
Anyhoo, previously on GCN...
So Polaris 10 moved to 3 CUs sharing the K$ & I$ for wiring purposes. Wonder if they're taking another step with just paired CUs while also moving to the (apparent) super-SIMD
GCN CU = SIMD0-3, 4x16ALU, up to 4 CUs sharing K$, I$
NG CU = SIMD0-1, 2x32, up to 2 CUs sharing K$, I$
<insert cascade of implications based on the 2017 optimization doc because caches>
Could be way off, chasing ghosts etc.

Personally , I don´t believe much in that change with NAVI as it seems far too radical to me. More likely Navi would be another boring GCN stuff pushed again to it´s limits to be at least competitive.
I believe, radical changes may come with new architecture....

That's Navi.
