Anyway, Ampere debuts on September 1st via a launch event from NVIDIA but actual product availability will likely be at least a week later. Ampere-based cards feature second-generation Ray Tracing cores, third-generation Tensor cores, PCI Express 4.0 support, and HDMI 2.1 and DisplayPort 1.4a connectors. VideoCardz also heard that Ampere is made on a 7nm process, which contradicts earlier rumors about NVIDIA having to resort to Samsung's 8nm node.
GeForce RTX 3090
This model uses the GA102-300 GPU with 5248 CUDA cores, a 384-bit memory bus and 24GB GDDR6X memory. The memory is clocked at 19.5Gbps and this results in 936GB/s of memory bandwidth. Custom models will have two 8-pin PCIe power connectors. The card has a TGP of 350W.
GeForce RTX 3080
This GA102-200 based model has a TGP of 320W, less power hungry than the RTX 3090 but still quite high so custom cards will have two 8-pin PCIe power connectors. The RTX 3080 reportedly has 4352 CUDA cores, a 320-bit memory bus and 10GB GDDR6X memory. The memory is 19Gbps, resulting in 760GB/s of bandwidth. A 20GB version will be offered by NVIDIA's add-in board partners.
GeForce RTX 3070
A bit more affordable is the GA104-300 based GeForce RTX 3070. This model is expected towards the end of September. Core count is unknown but it's rumored this model has a 256-bit memory bus with 8GB GDDR6 (non-X) memory. It has 512GB/s memory bandwidth and a TGP of 220W.
