RTX 3090 DLSS 5 support and VRAM evidence

Current DLSS 5 status

RTX 3090 sits outside the DLSS 5 hardware scope NVIDIA has published so far, so this record reads "not supported in the current official list". That scope names RTX 50-series Blackwell parts; Ampere is not part of it. Card record: 24 GB of VRAM, 10,496 CUDA cores, a 384-bit memory bus, 350 W board power, launched 24 September 2020. The conclusion covers DLSS 5 Neural Rendering only and leaves the older DLSS features this card already has unchanged.

Model record

What the source does and does not prove

The linked source is what places this model outside the announced scope. It does not claim the card is broken or obsolete — it only records that the published DLSS 5 hardware list does not include it.

Hardware specification of RTX 3090

These values come from the published GeForce RTX 30 Series specification table, which aggregates NVIDIA’s own product pages and architecture whitepapers. They describe the card itself; the DLSS 5 status above rests on a different source.

Launch date, die code, core count, bus width and board power are hardware facts. This page publishes no benchmark score and no ranking between models — more CUDA cores is not on its own a statement about DLSS 5 performance.

Vendor cards and laptop versions of RTX 3090 can differ in clocks, memory capacity and power limit, so match the exact variant before you buy.

Local DLSS5 Studio on RTX 3090

This card carries 24 GB, which clears the published 16 GB recommendation, so both the 1080p and the 4K video lanes are inside the published scope.

We publish no measured run for RTX 3090; our only measurement so far is the RTX 4090 (720p → 2560×1440 H.264 in 87.4 s (2.43 s/frame)). We do not extrapolate it to other cards, and this page does not claim one.

Feature scope for GeForce RTX 30 Series

These rows come from the same data set as the model table. A “yes” describes the published generation-level capability, not a guarantee that a given game enables it on this card.

Nearest models in the same series

• RTX 3090 Ti · 24 GB · 10,752 CUDA cores
• RTX 3080 Ti · 12 GB · 10,240 CUDA cores
• RTX 3060 · 12 GB · 3,584 CUDA cores
• RTX 3080 · 10 GB · 8,704 CUDA cores

The closest record in this series is RTX 3090 Ti (24 GB). Against RTX 3090, RTX 3090 Ti launched 18 months later, with 256 more CUDA cores and 100 W higher board power. Both share the same DLSS 5 status in this data set, and we publish no performance benchmark and no ranking between them.

Before you buy or upgrade

1. Confirm the exact RTX 3090 variant and its VRAM capacity — vendor and laptop versions differ.
2. Open the linked source and check whether your target game and driver publish a compatible path.
3. Treat “unconfirmed” as a prompt to wait for evidence; never infer support from a similar model.
