Blender benchmark score

44

Entry-level speed — fine for learning and lighter scenes.

VRAM

2 GB

Limited — best for simpler scenes and lighter workflows.

CUDA cores

384

Lower core count — adequate for lighter rendering workloads.

Architecture

Maxwell

Older architecture — check benchmark scores for a practical performance picture.

Memory bandwidth

16 GB/s

Lower bandwidth may become a bottleneck in texture-heavy or complex scenes.

Boost clock

1124 MHz

Lower clock speed — typical of older or workstation-class GPUs.

Render support

OptiX, CUDA

OptiX is typically the fastest option; CUDA provides a reliable fallback.

TDP

33 W

Low power — easy to cool and efficient for smaller builds.

Release year

2014
