Rumor: NVIDIA Ampere GeForce RTX 3070 and RTX 3080 specs surface
It has been a crazy year, and we have only just started. Lots of leaks and info mostly coming through unknown Twitter accounts. Today we can add to that as alleged specifications of the GeForce RTX 3070 and RTX 3080 have surfaced.
Of course, you'll need to take a ton of disclaimers in mind, and huge grains of salt perhaps even the size of golfballs when you read this one. But history has proven over and over again, that there often is validity (at least to some degree) to be found in these leaks. So here we go.
On both Asia based mydrivers and on a twitter account from ‘KittyCorgi’ info has appeared on two new NVIDIA GPUs, allegedly Ampere microarchitecture based. Two GPU models are named, GA103 GPU (RTX 3080) which would get 60 SMs (Streaming Multiprocessors aka shader core clusters) and then there is a mention of GA104 with 48 of them (RTX 3070). The GPU IDs seem to be reversed for whatever reason, we know, again rumors. If you multiply the clusters with 64-shader procs per cluster (which is what NVIDIA historically has been doing) each then you'd see 3840 Shader processors and 3072 shaders processors respectively. The leak mentions a 320-bit bus for RTX 3080, which could mean a 10GB memory GDDR6 configuration.
According to recent claims the chips are fabbed at Samsung, which sounds expensive over TSMC. Samsung's 7-nanometer process would use EUV, making the chips easier to fab. Historically TSMC always has been NVIDIA's biggest partner. TSMC has been fighting on many nodes to keep up with demand though. So then, 7nm EUV fabbed NVIDIA Ampere GPUs.
| GPU | SMs | Cores | Memory Size | Memory Bus | SKUs |
|---|---|---|---|---|---|
| Ampere GA103 | 60 | 3840 | 10/20GB GDDR6 | 320-bit | RTX 3080 |
| Ampere GA104 | 48 | 3072 | 8/16GB GDDR6 | 256-bit | RTX 3070 |
| Turing TU102 | 72 | 4608 | 24 GB GDDR6 | 384-bit | TITAN RTX/2080 Ti |
Rumors are that at GDC in march we'll see the first announcements on Ampere architecture (if it'll be called Ampere, yeah check that link my fellow web-hopper). KittyCorgi also drew up some block diagrams, obviously based on existing block diagram models. See attached.

Rumor: Nvidia Reportedly To Acquire Mellanox For $7B - 03/11/2019 07:56 AM
And let me state, this is a very solid rumor. Nvidia would have purchased the American company Mellanox Technologies, the manufacturer of InfiniBand and Ethernet network equipment. Reportedly, Nvidia...
Rumor: Nvidia GeForce GTX 1180 Expected in July? - 05/18/2018 07:06 AM
A new generation of graphics cards from Nvidia would become available in July, according to close-lipped sources from Tom's Hardware. The next-gen GPUs would be based on the Turing platform, but de...
Rumor: Nvidia Ampere might launch as GeForce GTX 2070 and 2080 on April 12th - 02/09/2018 03:07 PM
It's been silent with new graphics card releases from Nvidia. We've mentioned it a couple of times already, we really do not expect Volta with HBM2 to reach consumer grade graphics anytime soon. The...
Rumor: Next gen AMD Epyc processors will get 64 CPU cores - 11/02/2017 09:44 AM
And that would be 64 CPU cores per processor. AMD Epyc processors are intended for the enterprise and server market of course and seem to become a huge success story thanks to its terrific price an...
Rumor: Nvidia GeForce GTX 1050 2GB and 1050 Ti 4GB - 09/26/2016 08:13 AM
Over in the Asian countries there's quite a bit of speculation on the GeForce GTX 1050. Apparently there will be two models released, the regular 1050 with 2GB graphics memory yet also a 1050 Ti with...

Now, that's the RTX killer
Wonder what will the price be.
599/699?

Hmmh interesting. How big of a change is Ampere arch wise? Since I would guess 3072 would perform somewhere around 3072 with same clocks else. You know 3070 is around 2080 super.

Take xx80 series, half CUDA cores, get the xx60 series CUDA cores.
So 1920 cores for the ~300 bux version? With higher clocks and better IPC that would be somewhere between 2070 and 2070 Super performance. Gotcha.

up to 20 GB VRAM on 3080....I don't think they will launch a card with that kind of memory size for gamers - maybe on quadro version.
I am curious about RTX 3080 Ti...nothing on that yet....

The naming convention is strange: RTX 3080 is a high end product but it uses an uneven name: GA 103.
Previously Nvidia always used even names for high end products: 1080 - GP 104, 2080 - TU 104, etc

Interesting I expect these new models to have substantially more rt cores to make the feature actually usable. Either way I know this is just a rumor but the shader count looks good.

I call you cynical!
With their recent policy of cutting prices and AMD breathing down their neck I don't think that they will set these prices too high...

What this new generation should have is a much better performance/price ratio.
Even if 3080 is only "slightly" faster than 2080 Ti (or even a bit slower), if it costs only $600 (or less!), then it will be a great product !
And 3070 needs to return back to $400 price range, and if that is considerably faster than 2080, then a LOT of people will buy it.
Turing really stretched it with pricing, even NV fanboys like myself said ... NO, JUST NO. WAY too much.

Eh, no... it's a massive fail if it doesn't deliver considerably faster performance than turing, as turing barely upped the performance over pascal...
