Will those things come to pass? It is impossible to know right now, though the previous claims are all the more interesting in light of newer rumors.
NVIDIA's Next Generation GA100 Ampere GPU Rumored To Be Massive
What makes KittyCorgi's claim interesting is not just the raw size, but the notion of NVIDIA unpacking a 7nm GPU that big. If Ampere does end up measuring 826mm2, it seems more likely it would leverage a 12nm manufacturing process instead, which goes against previous rumors. But hey, anything is possible, right?
KittyCorgi also posted some diagrams they constructed based on the information they posted. Bear in mind that KittyCorgi is not claiming that these are leaked diagrams, hence why it is easy to spot details that are not consistent with real diagrams that NVIDIA produces.
That said, the supposed leaker makes the following claims about Ampere...
- INT32 Unit remains unchanged
- Double the FP32 Unit for shader proportion
- Double the Tensor Core performance
- Enhanced L1 data cache for more comprehensive functions
The diagram also points to a more advanced RT core design, which is an easy guess to make—RT cores are what power NVIDIA's real-time ray tracing efforts, and there is every reason to believe we will see both an increase in number of RT cores and a tweaked design to allow for more performance, when Ampere arrives.

KittyCorgi posted a couple of block diagrams as well. The one on the left supposedly depicts a GA103 GPU and the one on the right highlights the GA104 GPU. As with the other diagram, these are not leaked slides, but onces KittyCorgi constructed based on the information they are leaking.
According to KittyCorgi, the higher end GA103 GPU will feature 60 streaming multiprocessors (SMs), 10GB or 20GB of memory, and a 320-bit memory bus. That would give the GPU 3,840 CUDA cores, which is less than the GeForce RTX 2080 Ti, though that's assuming NVIDIA sticks with 64 CUDA cores per SM. Being a much denser GPU, according to the information posted, we could be looking at 128 SMs per core, which would give the GA103 GPU 7,680 CUDA cores.
The GA104, meanwhile, is said to feature 48 SMs for either 3,072 CUDA cores (64 CUDA cores per SM) or 6,144 CUDA cores (128 CUDA cores per SM), 8GB or 16GB of memory, and a 256-bit memory bus.
Why The Latest Leaked Ampere GPU Specifications Are Definitely (Maybe?) Real
Past rumors suggest Ampere will deliver big performance gains, both in rasterized rendering performance and ray-traced workloads. The supposedly leaked specifications would certainly keep NVIDIA in the lead, and probably by a big margin.
Why The Latest Leaked Ampere GPU Specifications Are Definitely Hogwash
If this does somehow come to pass, we are almost certainly looking at a server GPU, with consumer variants being less ambitious with better yields and better pricing. Still, our BS meter is ringing with this one.
There's also the source to consider. KittyCorgi has only been on Twitter for a month and has not built up a reputation as a leaker. So what this all boils down to is a fantastic claim by an unknown person with home-grown block diagrams.
We have little doubt Ampere will bring the boom, we just don't think the leaked specifications are going to play out.
