Hardware Support

Twitter user 'Kopite7Kimi' maybe provide the first technical data about nVidia's upcoming Ampere generation. These tweets are not more online, but were secured at the 3DCenter forums. Kopite7Kimi is not well known before, but seems to be have good sources - he wrote about some of nVidia "SUPER" cards before other sources, even before Videocardz. Nevertheless, you will need a (big) bag of salt for these data, because nothing is for sure - as it's usual for very first data. So, here is what Kopite7Kimi has written about Ampere:

nVidia Ampere HPC
reliable info: GA100 chip with a 6144 Bit HBM2 interface, doubled Tensor cores per SM
reliable info: GA101 chip as half of GA100, so with a 3072 Bit HBM2 interface (chip allegedly canceled recently)
not reliable info: GA100 with 8 GPC, each with 8 TPC = leads to 8192 CUDA cores
not reliable info: both chips at TSMC 7nm+ (with EUV)

nVidia Ampere Gaming
not reliable info: 5 gaming chips, all at Samsung 7nm (with EUV)

So, the GA100 HPC chip can be already described, if nVidia not changed the count of CUDA cores and TMUs in each SM. Anyway, based on this data it must be something of 4096, 8192 or 16384 cores - with 4096 too low and 16384 too high, leaves only 8192 cores as the most probable option.

nVidia GA100
HPC / professional solution of the Ampere generation
8 Graphics Processing Cluster (GPC) with each 16 Streaming Multiprocessors (SM) and each 8 Texture Processing Clusters (TPC)
each SM most likely contains (as before) 64 CUDA cores (CU) with 4 Texture Mapping Units (TMU), but 16 Tensor cores (doubled from Ampere)
gives a total of 128 Streaming Multiprocessors, which contain a total of 8192 CUDA cores, 512 TMUs and 2048 Tensor cores
PCI Express 4.0 (own assumption, but probably)
7nm+ (EUV) from TSMC
launch sometime in 2020 (other news points to first half of 2020)

If these 8192 cores holds for the GA100 chip, you can guess the core count for the other Ampere chips, like this ...

Chip	Segment	possible Cards	poss. Hardware	Predecessor
GA100	HPC	Tesla & Titan	8192 Cores @ 6144 Bit HBM2	GV100: 5376 Cores @ 4096 Bit HBM2
GA101	HPC	Tesla & Titan	4096 Cores @ 3072 Bit HBM2	-
GA102	Enthusiast	GeForce RTX 3080 Ti	appr. 6000-7000 Cores	TU102: 4608 Cores @ 384 Bit GDDR6
GA104	High-End	GeForce RTX 3070 & 3080	appr. 4000-5000 Cores	TU104: 3072 Cores @ 256 Bit GDDR6
GA106	Midrange	GeForce RTX 3060	appr. 2500-3000 Cores	TU106: 2304 Cores @ 256 Bit GDDR6 & TU116: 1536 Cores @ 192 Bit GDDR6
GA107	Mainstream	GeForce RTX/GTX 3050	appr. 1500-1800 Cores	TU117: 1024 Cores @ 128 Bit GDDR5
GA108	Entry	GeForce RTX/GTX 3040	appr. 1000 Cores	-

Looks like 30-70% more cores for each card, compared to the GeForce 16/20 series. And keep in mind, the Tensor cores will be doubled inside the Ampere SM, so the Tensor power will be much higher than this. You can expect the same (or more?) for the RT cores, so the ray-tracing power will be as well very much higher. Example: +50% more cores mean +200% more Tensor cores and probably +200% more RT cores - so a (speculated) 3-times ray-tracing power of Turing. Beside maybe some higher clocks and other internal improvements.

From the rumor mill: nVidia's next generation after Ampere is "Hopper"

Posted: 14 Nov 2019 06:41 AM PST

Twitter user 'Kopite7Kimi' tweets two highly interesting postings about the next nVidia generation - after Ampere. This next-next generation will be called "Hopper" in memory of computer pioneer Grace Hopper. The Hopper generation will see nVidia to work with Multi-Chip Module (MCM) designs, same like AMD do it with Zen 2's chiplet design. As like the Ampere posting from the same Twitter user earlier, take it with a grain of salt.

After Ampere, the next codename of GeForce is Hopper, in memory of Grace Hopper.

GeForce of Hopper will use MCM module to build giant cores.

Kopite7Kimi write about MCM designs for the gaming solutions of Hopper ("GeForce of Hopper"), but personally I'm very sceptical about it. It looks more a natural solution for HPC chips than for gaming chips. And as well, for the first generation a complete change (for the whole chip portfolio) looks like a big risk. I'm prepared for a MCM design for Hopper HPC, but not expect it for the gaming chips of the Hopper generation. This is maybe a goal for the nVidia generation after Hopper.

PS: When was the first time MCM rumors for graphics cards was discussed? I remember some speculations that ATI's R600 chip (Radeon HD 2900 series) would be MCM.
