As expected, NVIDIA announced a new generation of “Ada” cores at today’s special GeForce Beyond live event, as well as its first two products, the RTX 4090 and RTX 4080 graphics cards. The name Ada comes from the 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 has 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 chasing part, Ada uses the third generation RT core, which comes with 200 RT TFLOPs; and in the deep learning part, it has the fourth generation Tensor core, which can bring up to 200 RT TFLOPs. 1,400 Tensor TFLOPs. Overall, NVIDIA claims that Ada can get at least twice the total computing power than Ampere.
Among them, NVIDIA focuses on 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 lower resolution images, and can generate high resolution images through DLSS2 to increase the rendering speed. On DLSS3, NVIDIA has advanced the ability to render interleaved frames, 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 has 24GB of G6X memory and is “2~4 times faster” than the 3090Ti. It costs US $ 1,599 and is expected to be available on October 12. 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 at US$1,199, while the latter is priced at US$899. The RTX 4080 is expected to be available in November. In the live broadcast, NVIDIA 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 is more interesting is that NVIDIA has also announced that the old classic game “Portal” will be reimagined 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.
