They waited for a fab to give them a decent deal. Everything we've seen so far indicates Samsung undercut their competition to get a deal with nVidia.

What makes us special is we can create the most energy-efficient GPU in the world at anytime. And we should use the most affordable technology. Look at Turing. The energy efficiency is so good even compared to 'somebody else’s' 7nm.

I know, Nvidia must be sandbagging. They have 7nm 3080Ti for $500 ready for launch Just like Intel had...

Exactly.

"Why didn't AMD launch their Ryzen 2 on 14 nm if it is a so much better arch?"
"Why didn't AMD launch their Ryzen 2 on 14 nm to save money?"
"Why can't they compete on the same node?"

I don't even.

Turing, if it ported over to 7nm, will be definitely faster for sure.


The so called mid-range GA104 (which assumed to be RTX 3080) on 7nm will even outperform Titan RTX.

Could be,could not be. Depends on the size and the design.

Bold for emphasis.

Radeon VII has 60 CU's enabled (out of 64), for a total of 3840 cores.

The RX 5700 XT has 40 CU's, for a total of 2560 cores.

That's 33.3% less CU's, not half.



Nvidia isn't on 7nm because they launched Turing almost a year ago on 12nm before 7nm was ready and their refreshed products are still competing with Navi, so there is no need (unfortunately for us consumers). It's made all the more apparent since both in the lower midrange and in the upper end they still have no competition from AMD - namely to the GTX 1660, GTX 1660 Ti, RTX 2080 Super and RTX 2080 Ti. Also, Intel has problems with their 10nm process, Nvidia doesn't have any problems with the process per se, as that is handled by TSMC and Samsung. They might have implementation problems, but we don't know that. Word is that Nvidia will go straight to Samsung's 7nm EUV, as it will yield a bigger improvement at less cost and complexity than 7nm DUV.

Sorry was going to say Radeon 7 had 50% more CU. A year ago AMD released MI50/MI60. Nvidia being a "leader" could have hade a professional card like V100 on 7nm around the same time. I think people give Nvidia too much slack. They are actually in trouble if their 2 and 3rd business don't gain share. They already have the gaming PC market. They tried to increase the Revenue with high GPU prices and that did not work. Its only downhill from this point on.

Not a year ago, AMD launched the Radeon Instinct MI60 and MI50 on Nov 18th, 2018, whereas Nvidia launched their initial Quadro RTX line-up (RTX 8000, 6000 and 5000) on Aug 13th, 2018. That's more than a 3 month head start.

Instinct is competing with Tesla not Quadro RTX which was released December 7, 2017. AMD's first Quadro RTX competitor are only available in Macs currently.

When comparing the two you also have to add in the software compute stack which ROCm is still immature. It's only been out since Apr 20, 2016.
