Rumor: NVIDIA's Next Generation GeForce RTX 3080 and RTX 3070 "Ampere" Graphics Cards Detailed
NVIDIA's next-generation of graphics cards codenamed Ampere is set to arrive sometime this year, presumably around GTC 2020 which takes place on March 22nd. Before the CEO of NVIDIA, Jensen Huang officially reveals the specifications of these new GPUs, we have the latest round of rumors coming our way. According to VideoCardz, which cites multiple sources, the die configurations of the upcoming GeForce RTX 3070 and RTX 3080 have been detailed. Using the latest 7 nm manufacturing process from Samsung, this generation of NVIDIA GPU offers a big improvement from the previous generation.
For starters the two dies which have appeared have codenames like GA103 and GA104, standing for RTX 3080 and RTX 3070 respectively. Perhaps the biggest surprise is the Streaming Multiprocessor (SM) count. The smaller GA104 die has as much as 48 SMs, resulting in 3072 CUDA cores, while the bigger, oddly named, GA103 die has as much as 60 SMs that result in 3840 CUDA cores in total. These improvements in SM count should result in a notable performance increase across the board. Alongside the increase in SM count, there is also a new memory bus width. The smaller GA104 die that should end up in RTX 3070 uses a 256-bit memory bus allowing for 8/16 GB of GDDR6 memory, while its bigger brother, the GA103, has a 320-bit wide bus that allows the card to be configured with either 10 or 20 GB of GDDR6 memory. In the images below you can check out the alleged diagrams for yourself and see if this looks fake or not, however, it is recommended to take this rumor with a grain of salt.

GA103 - 60 SM (3480 SP) - 320-bit VRAM (10/20 GB) - assumed 3080
GA104 - 48 SM (3072 SP) - 256-bit VRAM (8/16 GB) - assumed 3070
7nm has not been favourable to higher clocks so far but has been considerably better in power consumption and efficiency. With frequency of around 2GHz (and some architectural improvements) GA104 is faster than 2080 Super and GA103 faster than 2080Ti.
Assuming Nvidia's usual chip numeration there should be another higher-end GA102 in the works...
So on paper this is not faster than the 2080TI. Right?
Obviously the smaller die would result in other benefit, such as lower TDP which I am really interested, and other stuff.
Do you guys think the GA103 card would be under 200W TDP?
Always looking at lower TDP cards, which are more silent as there is less heath to deal with by the cooler which translates into quieter card operation.
AM102 - ?? sm (????? SP) -RT Cores 108 - 384bit VRAM - assumed RTX Titan XXX
AM104 - 68 SM (4352 SP) - RT Cores 88 - 320-bit VRAM - assumed 3080ti -12gb-16gb-32gb
AM106 - 46 SM (2944 SP) - RT Cores 68 - 256-bit VRAM - assumed 3070ti - 12gb-16gb
7nm has not had much higher clocks so ?? but has been much better in power consumption/Eff.. With frequency of 1.7 - 2 GHz GA104 Could be faster than a 2080 Super and GA102 will be faster than 2080Ti. 20% >>??? 30% MAX , but RT-RT up to 50% MAX
Assuming Nvidia's usual chip numeration there should be another higher-end GA102 in the works...TITAN model!!depens on also who nvidia using?? TSMC. or SAMSUNG... rumored that TSMC 7nm is a bit better than samsungs 7nm at the moment?? (whether EUV or DUV)
Though I'd be happy to be wrong, as better grade products for the same or cheaper price is always a welcome.
I'm leaning towards big navi and ryzen 4700x, but if intel/nvidia high end ends up being 30+% fast for a 200-300 bucks more... than yeah I prob will go green.
But I would expect them to show data center products and perhaps give some hints about the upcoming consumer products.
Does anyone else see HBM making any headway in consumer graphics? When first released, AMD touted it as the second coming... but it turns out, it was fairly useless comparatively (I mean it did shrink gaps between NV cards at high resolutions, but never had the core horsepower in the first place for anything past 1440p).
or they could place 8 or even 12 TPC per GPC, also leading to 2x Perf.
People shouldn´t forget, nvidia gets about 2x the area 12nm vs 7nm.
I bet nvidia has plenty of ideas to get performance from that extra-area and doubled RT Perf is scaled 1:1 with SMs.
... wondering if it will still be 'big' compared to these (or w.e NV's high-end will be) or what...
This is so Nvidia can 'milk' the architecture as much as possible in the coming years. If they are running tests and they realise the they could push up to 60% more performance, they will release this performance in batches over the next generations of cards that will come in the next few years. So, yeah I am excited about the new cards, but Nvidia is always a business, and they won't release the full performance in the first batch, as this would leave them empty handed.
