Estimated Render Times for One Frame of Benchmark Scenes

OpenData Score: 41.03

Our estimated render times for one frame of benchmark scenes

Benchmark scores on this page are derived from Blender Open Data snapshot medians for classroom, junkshop, and monster. The one-frame render time chart is our derived estimate based on those medians and the legacy page formula, so it should be treated as an estimate rather than an official Blender timing.

Our Take on the NVIDIA GeForce GTX 645

The NVIDIA GeForce GTX 645, released in 2013, is a legacy GPU that offers basic rendering capabilities for Blender, but its limited VRAM and older architecture make it less suitable for modern, complex 3D projects.

Pros:

  • Affordable entry-level option for older systems
  • Compact design suitable for smaller builds

Cons:

  • Only 1 GB of VRAM limits rendering of complex scenes
  • Older architecture may struggle with modern Blender features

While the GTX 645 can handle simple tasks, it lacks the power and memory needed for demanding Blender workflows. Upgrading to a more recent GPU with higher VRAM and advanced features is recommended for serious 3D professionals.
