Once sites like Twitch add AV1 encoding support, these new graphics cards should be able to stream using this quick encoding format.
Previous generation NVIDIA GPUs could decode in AV1 format, but not encode in it. DLSS 3 also uses AI to generate frames between the ones your GPU renders, improving frame rates.įinally, both the 40 have AV1 encoding support. This technology lets your GPU render games at a low resolution and then uses Deep Learning to upscale it back to native resolution, giving better performance with minimal fidelity loss. Second, the new generation of Tensor Cores and the implementation of DLSS 3 dramatically improves DLSS (Deep Learning Super Sampling) performance. NVIDIA says that SER “dynamically reorganizes these previously-inefficient workloads into considerably more efficient ones, improving shader performance by up to 2X, and in-game frame rates by up to 25%”. There are several architectural changes and feature additions for both the RTX 40 compared to previous 30-series GPUs:įirst, the new generation of RT Cores and the introduction of Shader Execution Reordering (SER) dramatically improves ray tracing performance. The 4090 offers all the performance and technical impressiveness of the 4080 and more, thanks to its extra hardware horsepower. Like the RTX 4080, the 4090 is based on NVIDIA’s ‘Ada Lovelace’ architecture and manufactured using TSMC’s 4N process. Not only does this graphics card outperform previous generation cards, it also outperforms the RTX 4080, but costs substantially more than any other consumer card on the market. The NVIDIA GeForce RTX 4090 was the first current-gen NVIDIA GPU to hit the shelves, having launched in October 2022. It’s a high-end card, outperforming the best cards of the previous NVIDIA generation, like the RTX 3090.īased on the ‘Ada Lovelace’ architecture and built using TSMC’s 4N process, the RTX 4080 offers true next gen tech and performance, whether this is traditional rendering, deep learning-aided upscaling, or ray tracing. The NVIDIA GeForce RTX 4080 launched in November 2022, about a month after the RTX 4090. Bigger absolute framerate gain from DLSS.Flagship performance across all resolutions.Bigger relative (percentage) framerate gain from DLSS.Great for high refresh rate 1440p or 4K gaming.Currently about $1,000 cheaper for a custom card.
