The specifications and models for Nvidia's incoming RTX 3000-series of Ampere graphics cards have been revealed in an expansive leak. It not only breaks down what models will be available at launch, but also what their specifications will be, and how much power they'll consume.
The Ampere lineup will include three cards at launch: the RTX 3070, 3080, and 3090. These cards will be based on two distinct GPUs, with the 3080 using a modified 3090 GPU and the 3070 its own design. The top two cards will have 5,348 and 4,352 CUDA cores a piece, boosting to around 1,700MHz. They'll use GDDR6X memory, 24GB and 10GB respectively, at 19.5Gbps and 19Gbps speeds. That, combined with their 384-bit and 320-bit memory bus, will give them each 936GBps and 760GBps of overall bandwidth.
They'll need a lot of power, though. The 3090 will demand as much as 350w at stock, with the 3080 pulling 320w. That'll make these cards quite the little space heaters. To give that some context, the 2080 Ti only has a TDP of 250w, and the Titan RTX 280w.
The 3070 will have a more conservative 8GB of GDDR6 (non-X) running at 16Gbs over a 256-bit memory bus. That will give it a total bandwidth of 512GBps, pulling 220w from the wall. We don't have specs on its CUDA core count or clock speed, but expect the latter to be a little higher than the 2080s, but with significantly fewer cores to work with.
All new cards will support PCIExpress 4.0, HDMI 2.1, and DisplayPort 1.4a, with second generation Tensor and RT cores. Expect all three to debut before the end of September.
