The GeForce RTX 4090 is based on the new 5 nm "AD102" silicon, with a mammoth 76 billion transistors, crammed onto a die that's actually smaller than its predecessor. The "Ada" CUDA cores feature shader-execution reordering capabilities, which improve shader-bound ray tracing workloads and benefit from much higher clock-speeds. With it, NVIDIA is debuting 3rd generation RT cores that come with two new hardware components accelerating ray tracing more accurately, unburdening the CUDA cores and 4th generation Tensor cores, which leverage 8-bit and 4-bit math formats to increase AI inference performance by an order of magnitude over the previous-generation. The GeForce Ada graphics architecture heralds the 3rd generation of NVIDIA RTX real-time ray tracing technology, which blends conventional raster 3D graphics with real-time ray traced elements such as reflections, shadows, illumination, and motion-blur.
In addition, Ada seeks to further reduce the frame-rate impact of enabling ray tracing, by improving its entire ray tracing hardware set and introduces the new DLSS 3 feature with a breakthrough new AI-based complete frame-generation technique that creates unique new frames entirely using AI, without involving the bulk of the graphics rendering pipeline thereby doubling the frame-rate.
The NVIDIA GeForce RTX 4090 "Ada" is team-green's new-generation flagship product designed to achieve the "ends" of Moore's Law, if not through its "means." It promises a generational doubling in performance over what NVIDIA considered its previous flagship, the RTX 3080 (and not the RTX 3090/Ti) a nearly 50% improvement over the halo RTX 3090 while fitting into similar typical-power envelopes as the RTX 3090, at 450 W.
