[Think Computers] NVIDIA Maxwell 20nm GPU Lineup Delayed Until 2015 - Page 5

post #41 of 193
To be honest I am not surprised that 20nm is delayed, its getting harder and more expensive to do these shrinks. In the future expect longer GPU generations as the process gets smaller.

I realize the URL says 22nm but read the article.

Nvidia has the most to lose from bad processes or immature ones. They sort of depend on a giant die in order to be competitive, and the main reason why they are so successful in the high end is that they make giant dies and basically just brute for against AMD. It's essentially just a "MOAR COARS" approach, but it works a lot better because GPU workloads scale across thousands of cores much better than CPU workloads scale to 4 or more cores.

If Nvidia is unable to make a massive 500mm^2+ 20nm part by 2015 and AMD can make a 375mm^2 part or so, Nvidia is in serious trouble. I say this because AMD has a history of using their die size far more effectively. If Hawaii was as efficient per mm^2 as Kepler, it wouldn't be nearly as competitive at all.

Although, to be honest, I wouldn't be surprise if Nvidia did with like they did with Kepler, and released GM104 as the "high end" for a while, charged $550+ for it, then released GM100/GM110 as a new chip and move GM104 down a segment with a marketing model number bump.

Nvidia isnt skipping 20nm. If they wont goto 20nm, they sure as hell wont go to 14. The reason we're at 28nm for so long is because of the cost structure. Once it breaks even for them they'll adopt 20nm. According to the graphs, it looks like that's towards the end of 2014 and early 2015. Knowing Nvidia, they'll move their top of the line graphics card to 20nm while keeping the lower cost ones (and lower profit) on 28 because margins are better.

Arguably, Maxwell might have a better performance per transistor count than AMD because Nvidia pushed so hard for performance per watt over the last few years. Case and point, even though Nvidia has a disadvantage with mining, the GTX 750 Ti actually does better performance per watt than AMD 280's and 290's.

All I read was nvidia will continue to milk it.

Maxwell 880 ti on 28nm then just die shrink it when 20nm is ready

A huge piece of silicon that you cut your chips from.

Oh ha,ha, jokes on me.

I am not sure what people are expecting. GPUs now a days are slowing down. We used to get a new GPU every 6 Months. Just look at AMD. HD 7970 to 290X took almost 2 years in the same processing node. From the time 290X was released i would give AMD another 1-2 years before they replace it. To fill the gab they will release Dual GPU. Nvidia is in the same situation. They might release a GTX790 or something along those like in 4-6 months just so it gives Titan Z some room.
