NVIDIA GeForce RTX 3090 and GeForce RTX 3080 specifications leaked

We have received a confirmation on the upcoming GeForce RTX 30 lineup.

RTX 30 series: it is all about the memory

According to our sources, NVIDIA is set to launch three SKUs in September: RTX 3090 24GB, RTX 3080 10GB and RTX 3070 8GB. We have learned that board partners are also preparing a second variant of the RTX 3080 featuring twice the memory (20GB). However, that model is yet ‘TBA’ and it might launch later. This post is only about RTX 3090 and RTX 3080.

With GeForce RTX Ampere, NVIDIA introduces 2nd Generation Ray Tracing Cores and 3rd Generation Tensor Cores. The new cards will also support PCI Express 4.0. Additionally, Ampere supports HDMI 2.1 and DisplayPort 1.4a display connectors.

NVIDIA GeForce RTX 3090 features GA102-300 GPU with 5248 cores and 24GB of GDDR6X memory across a 384-bit bus. This gives a maximum theoretical bandwidth of 936 GB/s. Custom boards are powered by dual 8-pin power connectors which are definitely required since the card has a TGP of 350W.

The GeForce RTX 3080 gets 4352 CUDA cores and 10GB of GDDR6X memory. This card will have a maximum bandwidth of 760 GB/s thanks to the 320-bit memory bus and 19 Gbps memory modules. This SKU has a TGP of 320W and the custom models that we saw also require dual 8-pin connectors.

The GeForce RTX 3070 also launches at the end of next month (unless there is a change). We can confirm it has 8GB of GDDR6 memory (non-X). The memory speed is estimated at 16 Gbps and TGP at 220W. The CUDA Core specs are still to be confirmed.

The data that we saw clearly mention the 7nm fabrication node. At this time we are unable to confirm if this is indeed true.
