As expected, NVIDIA announced a new generation of “Ada” cores at today’s GeForce Beyond special live event, as well as its first two products, the RTX 4090 and RTX 4080 graphics cards. Ada’s name comes from British female mathematician Ada Lovelace, and will use TSMC’s 4N process and Micron’s G6X memory, which can have as many as 76 billion transistors on a chip.
In the rendering part, Ada is equipped with a new multi-stream processor, which can provide up to 90 Shader TFLOPs, and has twice the energy efficiency of the previous generation. In the light pursuit part, Ada uses the third-generation RT core, bringing 200 RT TFLOPs; and in the deep learning part, it is equipped with the fourth-generation Tensor core, which can bring up to 200 RT TFLOPs. 1,400 Tensor TFLOPs. Overall, NVIDIA claims that Ada can have at least twice the total computing power than Ampere.
Among them, NVIDIA focuses on the DLSS3 technology based on the fourth generation core. NVIDIA introduced AI deep learning technology in DLSS2, which can perform AI reinforcement at the pixel level, so that the graphics card only needs to output lower-resolution images, and can generate high-resolution images through DLSS2 to increase the rendering speed. On DLSS3, NVIDIA has even advanced to the ability to render frame insertion, using Optical Flow Field (optical flow field) technology to further increase the number of frames without GPU or CPU operations.
The first cards to ship with Ada will be the RTX 4090 and RTX 4080. The RTX 4090 is equipped with 24GB of G6X memory and is “2~4 times faster” than the 3090Ti. It is priced at US$1,599 and is expected to be available on October 12th. On the other hand, the RTX 4080 is also “2~4 times faster” than the 3080 Ti, and will be available in two versions, 16GB G6X memory and 12GB G6X memory, the former is priced from US$1,199, while the latter is priced from US$899. The RTX 4080 is expected to be available in November. In the live broadcast, NVIDIA actually did not add much to these two products (or more about Omniverse), so the detailed specifications will have to wait for NVIDIA to announce it separately.
What’s more interesting is that NVIDIA also announced that the classic old game “Portal” will be re-imagined and rendered with RTX technology, and “Portal with RTX” has been launched. This will be available as free DLC in November for players who have already purchased Portal.
