From what is known, NVIDIA Ampere will have six GPUs: GA100, GA102, GA103, GA104, GA106, and GA107. Obviously, the GA100, equipped with HBM2 memory, will be the high-end Ampere GPU, probably used for a Titan and a high-end Quadro. The GA102 to GA107 GPUs, equipped with GDDR6 memory, will be the mainstream Ampere GPUs, probably used for the GeForce family.
NVIDIA Ampere will likely be a beast at compute, for its GPUs have many CUDA cores. The high-end GA100 GPU is expected to feature 8192 CUDA cores, 2048 Tensor cores, 128 RT cores, and a 6144-bit memory bus. However, the mainstream chips are, also, impressive, for the mid-range GPU, the GA103, contains 3840 CUDA cores, the same amount of CUDA cores in a Quadro P6000.
GA100: 8192 CUDA cores, 2048 Tensor cores, 128 RT cores, and a 6144-bit memory bus
GA102: 5376 CUDA cores, 1344 Tensor cores, 84 RT cores, and a 384-bit memory bus
GA102 (cut down): 4928 CUDA cores, 1232 Tensor cores, 77 RT cores, and a 352-bit memory bus
GA103: 3840 CUDA cores, 960 Tensor cores, 60 RT cores, and a 320-bit memory bus
GA104: 3072 CUDA cores, 768 Tensor cores, 48 RT cores, and a 256-bit memory bus
GA104 (cut down): 2304 CUDA cores, 576 Tensor cores, 36 RT cores, and a 256-bit memory bus
GA106: 1920 CUDA cores, 480 Tensor cores, 30 RT cores, and a 192-bit memory bus
GA107: 1280 CUDA cores, 320 Tensor cores, 20 RT cores, and a 128-bit memory bus
With these specifications and past NVIDIA tendencies, much information regarding these cards can be extracted. It is known that the GA103 and GA104 are home to the GeForce GTX 3080 and the GeForce GTX 3070 respectively, but from past NVIDIA trends, it can be known that the GeForce GTX 3060 will, also, have the cut-down GA104 GPU. Possible VRAM amounts can be extracted, too.
