NVIDIA Reportedly Moving Ampere to 7 nm TSMC in 2021
A report straight from DigiTimes claims that NVIDIA is looking to upgrade their Ampere consumer GPUs from Samsung's 8 nm to TSMC's 7 nm. According to the source, the volume of this transition should be "very large", but most likely wouldn't reflect the entirety of Ampere's consumer-facing product stack. The report claims that TSMC has become more "friendly" to NVIDIA. This could be because TSMC now has available manufacturing capacity in 7 nm due to some of its clients moving to the company's 5 nm node, or simply because TSMC hadn't believed NVIDIA to consider Samsung as a viable foundry alternative - which it now does - and has thus lowered pricing.
There are various reasons being leveraged at this, none with substantial grounds other than "reported from industry sources". NVIDIA looking for better yields is one of the appointed reasons, as is its history as a TSMC customer. NVIDIA shouldn't have too high a cost porting its manufacturing to TSMC in terms of design changes to the silicon level so as to cater to different characteristics of TSMC's 7 nm, because the company's GA100 GPU (Ampere for the non-consumer market) is already manufactured at TSMC. The next part of this post is mere (relatively informed) speculation, so take that with a saltier disposition than what came before.
That NVIDIA is looking to tier its manufacturing process across high-end and the rest of its product stack (with 7 nm for high-end and 8 nm for the rest of it) would become a headache for themselves and for consumers, should NVIDIA just have two suppliers for the same graphics products. There would likely be need for some changes in the power delivery designs, there are a range of new quality assurance tests that have to be taken for the new silicon, and NVIDIA would set itself up for legal troubles should they just silently update the manufacturing process on high-end models - not only would early adopters be understandably miffed about their product having evolved over time, as there could be some claims regarding 8 nm-based models being bought after the 7 nm ones are launched. And if NVIDIA were to put a sticker on retail boxes updating the 8 nm to 7 nm, well, then any user could just decline to purchase any 8 nm cards, and only look for the 7 nm versions, which might leave NVIDIA with a real immovable supply problem.
No. If this report checks out, NVIDIA will likely launch the newly produced top-end Ampere cards (we're thinking RTX 3090, RTX 3080 and RTX 3070) in 7 nm Super versions, taking a page from their RTX 20-series book. The introduction of a higher-performing product built in 7 nm within a whole new series would protect NVIDIA from legal troubles while allowing them to publicly announce the transition. This would keep early adopters "happy" in the respect that this is a whole new product launch - users would receive that much better than by feeling that they were beta testers for NVIDIA's tango with Samsung, as reception for the 20-series Super cards shows. The usage of this new process would also allow NVIDIA to improve performance further over the original 30-series cards, due to lower leakage and higher potential operational frequencies - perhaps in addition to NVIDIA's 20-series strategy of trickling down bigger GPU designs.

Samsung 8nm is equivalent to TSMC 10nm which is equivalent to Intel 14nm.
I'm upgrading from Vega 64 so I've saved and ordered a 3090. If AMD announce a GPU that is better than a 3080 in terms of performance at 4k with RT on then I'll just cancel my 3090 preorder and wait for the AMD card since it will likely be vastly more efficient.
Guess we just found out, move to TSMC 7nm,and clocks above 2Ghz should become achievable, there's your Super parts, phase out non-Super.
That being said, how much capacity does TSMC 7nm actually have for Nvidia, since WSA's are usually negotiated a year or so in advance.
If there is nothing coming into etailers which sometimes disclose it and you see how little they move.. 200 gpu's in a month lot of demand ?
when they are selling 1000 a month of a single sku every month prior to announcement.
Samsung 8nm might not yield the behemoth chips, maybe g6x production is struggling, there is a lot of new things here for nvidia and they rushed it a bit too.
if its even arrived before 2021, that is
You only need that much if you play on 4K with resolution scaling and all BS
WE DONT JUDGE AROUND HERE. EXCEPT APPLE PRODUCTS.
Nvidia is just ridiculous for this moveand prove that RTX 3000 was a quick release cause they fear AMD...
AMD has a REAL new architecture...
The only reason I could buy an RTX is my Nvidia Gsync screen
Because a 20GB 3080 on TSMC will not only clock higher but do so whilst consuming ~30% less watts.GloFo couldnt get their 7nm up and running so abandoned chasing the cutting edge of node development and is concentrating on 12nm and older nodes for customers not at the bleeding edge.
It's not a single apple-to-apples easy number as this was GloFo to TSMC, 8GB to 16GB, and 64CU vs 60CU but it's probably the closest comparison of 14nm to 7nm there is because at least the class of product and architecture remain completely unchanged (both a ~300W, 60-ish CU, HBM2, GCN 5, 2048-bit design running on identical drivers and software stack, both available to the market simultaneously).
30% may not be accurate but it's kind of in line with TSMC's claims about their 7nm node - when it first launched TSMC were saying that it could go 30% faster at the same power budget or up to 50% lower power at the same performance levels. "Up to" comes with all the usual marketing-speak caveats, ofc.
