News On GPU Process Nodes
#1
http://www.fudzilla.com/news/processors/...ip-factory
Quote:We have learned that high performance discrete GPUs will never make it to 20nm, simply as process has too much power leaks and poor yields with big cores. The GPU industry will move to 16nm FinFET at TSMC in 2016, or 14nm with Samsung and GlobalFoundries at about the same time. After 16nm FinFET, TSMC is planning to transition to 10nm as early as late 2016, but we believe that this is very optimistic timing.

A $16 billion investment may sound like a lot of money, but Intel has invested more than $6 billion in Israel based fabs since 2006. Intel is right now preparing Israel fabs for 10nm, while Ireland is manufacturing most of Intel's 14nm SoCs right now. The next node after 10nm for Intel is 7nm, probably happening before the end of this decade.

Back in 2009 in Albany, New York state, GlobalFoundries executives and chaps from The College of Nanoscale Science and Engineering were telling us that each transition cost to a new node grows exponentially. Despite large R&D investments, it is getting harder to transition from 28nm to 20nm to 14nm. This is one of the reasons why Samsung and GlobalFoundries have joined forces for their 14nm push.

Most people have realized this when Nvidia launched the gm204

All except some die hard AMD fans who kept/keep insisting tha AMD will release this 20nm monster GPU to pound nvidia into a ball of muck.

Yeah, not happening.

So this means the 390x (or whatever it may be) is going to be a very large 28nm chip. Its gonna be large and very power hungry. This is why they need water cooling. It will sport a closed loop cooler, just like their top of the line CPUs need a closed loop cooler.

Also, it will be extremely power hungry. It will not have drastic power savings like maxwell. AMD fans are trying to say that the tonga is this great improvement in performance per watt. What?????
I struggle to see where it moved the ball at all, maybe we might can say barely but seriously..........i am not sure it is more effiecent than Tahiti at all. Perhaps their overclocked Tahitis, like the 7970ghz. But, up against the 7970 or 7950, tonga doesnt appear any more efficient.

The 390x will be extremely power hungry. The water cooler may be able to cool it though. But all of the "leaks" so far are made up. They are just estimations, which anyone can do. We have the supposed specs, these leaks are just made up. The truth is, the launch is still out there. And there are no drivers or cards in the hands of anyone who could leak them.

Also, there is now supposed leaks of a whole line up, even a 395 x2. This is supposed to be a two fiji chips on a single die. Its totally not happening. Bogus, completely bogus.

The CLC will be able to cool a 390X, and a 390X2. R9 295X2 showed you can cool 650W with a 120x38mm radiator. Imagine the capacity of a 120x60mm radiator, like the one used on the ASUS ROG ARES II.

if the 390x uses almost as much power as a 295 x2 by itself, it is completely not practical.

The 390x will use about 140% the power of a 290x. Give or take.

So, two of them will be similar to the power requirements of three 290x chips on one PCB. How many power connectors would you need for such a chip. So you really think AMD will design a single slot card with such a massive tdp? At the very best case, its gonna be like a titan z plus a gtx 780ti all on one chip.

I really have my doubts. Its really pushing the edge....
Not the cutting one either
