NVIDIA GeForce RTX 30xx graphics cards support frame generation, but… from AMD. One of the company’s executives says that NVIDIA can implement their own generation.
In an interview with Digital Foundry, NVIDIA Vice President of Applied Deep Learning Research, Bryan Catanzaro hinted that the company might transfer DLSS 4 frame generation to RTX 30xx. However, they have hardware differences that complicate this.
Alex Battaglia from Digital Foundry asked Catanzaro about frame generation on previous generation graphics cards: “Now that it [DLSS 4] fully operates on tensor cores… what then prevents it from working on RTX 3000?”
Catanzaro responded: “I think it is primarily a matter of optimization and design, followed by the best user experience. We are launching this frame generation, the best Multi-Frame Generation technology with the 50xx series, and we will be able to see what we can ‘squeeze’ out of older hardware in the future”.
Remember, when NVIDIA introduced Frame Generation with GeForce RTX 40 graphics cards, Catanzaro explained that this feature became exclusive to new graphics cards because they had a significantly improved hardware accelerator Optical Flow, unlike the RTX 30 series. Then he also said that theoretically it might be possible to transfer the technology to old hardware, although it probably won’t be as beneficial.
New Multi-Frame Generation does not use Optical Flow, shifting the work to tensor cores. However, according to Catanzaro, its requirements for tensor cores are higher — accordingly, older GPU architecture will perform worse.
