NVIDIA GeForce 840M
Maxwell GPU best suited to lighter Blender scenes, learning workflows, and budget-conscious rendering setups.
Last updated: March 31, 2026
44
Entry-level speed — fine for learning and lighter scenes.
2 GB
Limited — best for simpler scenes and lighter workflows.
384
Lower core count — adequate for lighter rendering workloads.
Maxwell
Older architecture — check benchmark scores for a practical performance picture.
16 GB/s
Lower bandwidth may become a bottleneck in texture-heavy or complex scenes.
1124 MHz
Lower clock speed — typical of older or workstation-class GPUs.
OptiX, CUDA
OptiX is typically the fastest option; CUDA provides a reliable fallback.
33 W
Low power — easy to cool and efficient for smaller builds.
