Nvidia RTX 5090 vs 4090: Architecture
First off, the Nvidia RTX 5090 is developed on the latest Blackwell architecture whereas the RTX 4090 is developed on the Ada Lovelace architecture. At this point, the Ada architecture is over two years old. In addition, RTX 5090 is manufactured on TSMC’s 4nm (N4P) process node, which results in 92 billion transistors on the die. On the other hand, RTX 4090 is fabricated on TSMC’s 5nm (4N) process node and packs around 76.3 billion transistors.
As for CUDA cores, RTX 5090 is the first Nvidia consumer GPU that features over 20,000 CUDA cores (21,760, to be precise). RTX 4090 houses 16,386 CUDA cores. Here, thanks to the Blackwell architecture and improved 4nm node, RTX 5090 packs 32% more transistors.
Overall, Nvidia says RTX 5090 delivers close to 2x better performance than its predecessor, RTX 4090. In AI workloads, the performance difference is nearly 3x. And all of this is possible at a lower frequency which is surprising. The RTX 5090 card has a peak frequency of 2.41GHz, slightly lower than the RTX 4090’s 2.52GHz peak clock speed.
Nvidia RTX 5090 vs 4090: Performance
Moving to performance, Nvidia has disclosed some numbers comparing the RTX 5090 and 4090. The Shader cores on RTX 5090 can deliver up to 125 TFLOPS whereas the RTX 4090 can output up to 83 TFLOPS. Here, RTX 5090 leads by 50%.
The 5th-gen Tensor cores on RTX 5090 can perform up to a whopping 3,352 trillion operations per second (TOPS) on AI workloads. The 4th-gen Tensor cores on RTX 4090 can process up to 1,321 AI TOPS, which means RTX 5090 is around 2.5x faster than RTX 4090 on AI tasks.
Next, the 4th-gen Ray Tracing cores on RTX 5090 can deliver graphics performance up to 318 TFLOPS. And the 3rd-gen RT cores on RTX 4090 deliver up to 191 TFLOPS. In Ray Tracing performance, the RTX 5090 leads by around 66%.
In gaming benchmarks that Nvidia shared, the company says RTX 5090 offers 2x better performance than RTX 4090 in titles like Cyberpunk 2077, Black Myth: Wukong, and Alan Wake 2. In a demo that Nvidia showcased, RTX 5090 with DLSS 4 produced 238 FPS in Cyberpunk 2077. The RTX 4090 with DLSS 3.5 could only reach up to 109 FPS.
As for Generative AI workloads, RTX 5090 again doubles the AI performance when running the Flux.dev image generation model locally.
Coming to DLSS 4, it brings a groundbreaking Multi Frame Generation feature which is only available on the RTX 50 series cards. However, other improved DLSS 4 features like Frame Generation, Ray Reconstruction, Super Resolution, etc. are available on RTX 40, 30, and 20 series cards.
