Part of the datasheet for the future GeForce RTX 3090, 3080, and 3070 appeared this weekend. Here are all the news.
We already know most of the GeForce RTX 3070, 3080, and 3090 datasheets. As a reminder, the future of NVIDIA graphics cards will be introduced tomorrow, Tuesday, September 1, 2020. They will be introduced in September. Video memory in GDDR6X and GDDR6, PCI Express 4.0 or 7 nm burn confirmation, here you will find the latest information.
GeForce RTX 3090, 3080 and 3070: Overview of Datasheets
Therefore, The top-of-the-range RTX 3090 offers 5248 CUDA cores with 1695 MHz and 24 GB in GDDR6X with a 384-bit bus at 19.5 Gbps. It offers a bandwidth of 936 GB /sec. Its total energy consumption (Total Graphics Power or TGP, not to be confused with Thermal Design Power, TDP) would a priori be 350 W. Its power supply would also be via a 12 PIN PCI-E connector. 4.0 for Founders Edition (FE). Is 350 W a priori. Power is also supplied via a 12-PIN PCI-E connection. 4.0 for publishers (FE). It will likely be 8 pin PCI-E on a dedicated card like the Zotac in the image above. It must also support a new SLI technology called NVLink.
The GeForce RTX 3080 would offer 4352 CUDA cores at 1710 MHz, with 10 GB of GDDR6X 320 bits and at 19 Gbps. Some models would come up to 20 GB of video memory. The bandwidth would be 760 GB / sec and the TGP 320 watts. The power supply would be the same as the RTX 3090 (a 12 PIN for the FE and a dual-pin of 8 on the Custom).
Finally, it seems that the GeForce RTX 3070 will offer 8 GB of video memory in GDDR6 (and not in X therefore), with a 256-bit bus and at 16 Gbps. The bandwidth would be 512 GB / sec and the TGP 220 watts. CUDA cores do not seem to be known yet, however.
VideoCardz reporters also mention support for HDMI 2.1 and Display Port 1.4a. The first two will also benefit from second generation ray tracing cores and third generation tensor cores. The current P.-D.G. of the firm, Jen-Hsun Huang, is expected to present them in just under 24 hours.
