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.

Benchmark performance
This chart estimates how many seconds this GPU takes to render one frame of each standard Blender benchmark scene, so you can compare practical rendering speed at a glance.
These are single-frame estimates derived from Blender Open Data benchmark medians at the scene sample counts, not full-animation render times or guarantees for every real project.
