Pra mim ainda não ficou claro se o hardware da AMD tem algo pra competir com os Tensor Cores da Nvidia, provendo algo similar ao DLSS. Porque lá nas placas da Nvidia já ficou claro que pra ter RayTracing a uma taxa alta de quadros tem que ter DLSS junto.
Se o hardware do
Xbox Series X|S e PS5 tiverem suporte apenas a RayTracing, sem DLSS, o suporte a RayTracing vai ser limitado nos consoles porque o RayTracing é bem pesado.
Aparentemente sim: "It's worth noting that Nvidia also has Tensor cores in its Turing architecture, which are used for deep learning and AI computations, as well as DLSS (Deep Learning Super Sampling), which has now been generalized with
DLSS 2.0 (and DLSS 2.1) to improve performance and image quality and make it easier for games to implement DLSS. So far, AMD has said nothing about RDNA 2 / Navi 2x including Tensor cores, though it mentioned an upcoming Super Resolution feature that may be mostly equivalent to DLSS. AMD's CAS (Contrast Aware Sharpening) and RIS (Radeon Image Sharpening) already overlap with DLSS in some ways, and Super Resolution will be part of the open FidelityFX suite, so we'll have to wait and see how it compares against DLSS. Even without Tensor cores, it may be possible to do all the inference side of a DLSS-style algorithm using the FP16 capabilities of Navi 2x."
Tirado do
Xbox: "To deliver on this vision we wanted to leverage the full capabilities of RDNA 2 in hardware from day one. Through close collaboration and partnership between
Xbox and AMD, not only have we delivered on this promise, we have gone even further introducing additional next-generation innovation such as hardware accelerated Machine Learning capabilities for better NPC intelligence, more lifelike animation, and improved visual quality via techniques such as ML powered super resolution. "
Lembra daquela conversa sobre PS5 ser RDNA 1.5? Então na verdade o hardware é RDNA 2 , mas o software Vulkan não consegue utilizar todas as instruções presente no RDNA 2 por isso o Phil falou que o
Series S/X são os únicos consoles full compatíveis com essa plataforma.
Isso deve trazer um impacto na performance que só saberemos no futuro.
