As detailed earlier, the RTX 30 series is based on Ampere GPU architecture, packing 28 billion transistors, made on Samsung's 8nm manufacturing process.
The BFGPU RTX 3090, as Nvidia likes to call it, is a whole different beast, packing 10496 CUDA cores and providing 35.7 TFLOPs of single-precision performance. It packs 24GB of 19.5Gbps GDDR6X memory on a 384-bit memory interface.
The GPU boosts up to 1.7GHz on the RTX 3090, and it has a 350W TDP, which means it will need two 8-pin PCIe power connectors.
The RTX 3080 packs 8704 CUDA cores, with 29.8 TFLOPs of single-precision compute performance. The GPU boosts up to 1.71GHz, and it comes with 10GB of 19Gbps GDDR6X memory on a 320-bit memory interface. It has a 320W TDP and will also need two 8-pin PCIe power connectors.
The RTX 3070, packs 5888 CUDA cores, and its GPU boosts up to 1.73GHz. It has 8GB of 16Gbps GDDR6 memory on a 256-bit memory interface and has a 220W TDP, so it will need a single 8-pin PCIe power connector.
The RTX 3080 comes first, RTX 3070 in October
According to earlier information, the RTX 3080 will launch first, on September 17th, starting at $699. It will be followed by the RTX 3090, which will be available on September 24th, starting at $1499. The RTX 3070 comes in October and will be starting at $499.
