NVIDIA GeForce RTX 4090
High-end Ada Lovelace GPU built for large Blender scenes, heavier assets, and very fast Cycles rendering.
Last updated: March 31, 2026
11,698
Very fast — handles complex scenes and production renders with ease.
24 GB
Plenty of room for large scenes, dense geometry, and 4K–8K textures.
16,384
Very high core count — excels at heavy parallel rendering workloads.
Ada Lovelace
Current-generation design with efficient ray tracing and strong Cycles throughput.
1,010 GB/s
Very high throughput — keeps up with complex shading and large texture workloads.
2.52 GHz
High clock speed — helps with viewport responsiveness and per-core performance.
OptiX, CUDA
OptiX is typically the fastest option; CUDA provides a reliable fallback.
450 W
High power draw — plan for a strong PSU and good airflow.
