The GeForce RTX 4090 is a phenomenally fast graphics card with a base clock speed of 2.23GHz. This is over 600MHz faster than previous generation RTX boost clocks. This raw power is backed up by the latest iterations of ray tracing and tensor cores. These new RT cores deliver spectacular performance, and are supported by an amazing innovation called Shader Execution Reordering (SER) which allows more immersive ray-traced worlds to be rendered faster than ever before. NVIDIA has also made great strides with their AI rendering, thanks to their advancements in DLSS technology. Utilising DLSS 3, the RTX 4090 is able to boost frame rates even in CPU-limited games like Microsoft Flight Simulator.
