Architecture Overview
The NVIDIA RTX 5090 Super is built on a refined 4 nm process, featuring 12,288 CUDA cores organized into 96 streaming multiprocessors. It introduces the third\u2011generation Tensor cores with support for DLSS 4, which includes temporal reconstruction and motion vector generation. The RT cores are also upgraded, delivering higher throughput for ray\u2011triangle intersections. The GPU is paired with 24 GB of GDDR7 memory on a 384\u2011bit bus, providing a theoretical bandwidth of 1 TB/s.
AMD’s RX 8900 XT employs a 5 nm RDNA 3 architecture, integrating 16,384 stream processors across 64 compute units. It includes 64 MB of Infinity Cache to reduce memory latency and features 24 GB of GDDR6X on a 384\u2011bit interface. The RDNA 3 design incorporates dedicated ray tracing accelerators and supports FSR 4, which leverages spatial upscaling and motion vectors.
