About these estimates
Times estimate one frame of each benchmark scene from the same runs, Blender version and backend as the displayed Cycles score. The calculation uses 240 samples for Junkshop, 256 for Monster and 300 for Classroom, plus a 19% estimation buffer. Actual project render times vary. Results from different Blender versions may not be directly comparable. The benchmark data groups this model’s hardware variants together.
Is T400 4 GB good for Blender?
A concise editorial read on where this GPU looks strong, the tradeoffs to keep in mind, and who it suits best.
What stands out
- 4 GB VRAM
- Turing architecture
Tradeoffs to know
- Meets Blender’s 2 GB VRAM minimum but falls below its 8 GB recommendation for Windows/Linux. Usability depends on GPU and driver compatibility and your scene’s memory needs.
- The benchmark groups hardware variants together; it is not a separate measurement of this exact hardware version or the benefit of extra VRAM.
Who should choose it
- Turing GPU with 4 GB VRAM, below Blender’s recommended 8 GB. Check scene memory needs and GPU compatibility before buying.
