Which GPU should you choose for Blender?
RTX 3080 Ti is the stronger Blender rendering pick here based on benchmark score.
Cycles rendering performance
RTX 3080 Ti leads by 313.6% in the Renderjuice Blender benchmark model (4,843 vs 1,171). For render-time-first decisions, that is the card to prioritize.
VRAM and scene capacity
RTX 3080 Ti has more scene headroom with 12 GB of VRAM versus 8 GB on CMP 40HX 8 GB. That matters most for large environments, dense geometry, high-resolution textures, and less optimized production files.
Power ratings and cooling
CMP 40HX 8 GB is the lower-power option at 185 W TDP, compared with 350 W for RTX 3080 Ti. If render speed is close, that can make CMP 40HX 8 GB easier to cool and run quietly.
Is the upgrade worthwhile?
RTX 3080 Ti is the straightforward performance pick, while CMP 40HX 8 GB needs a price, power, availability, or compatibility advantage to make more sense.
Comparison summary
RTX 3080 Ti leads the Blender benchmark score by 313.6%.
Fastest in Cycles: RTX 3080 Ti 314% faster than CMP 40HX 8 GB.
Most VRAM: RTX 3080 Ti 50% more VRAM than CMP 40HX 8 GB.
Lowest power draw: CMP 40HX 8 GB 47% lower rating than RTX 3080 Ti.
Cheapest: Cannot compare Price unavailable for some GPUs.
Best value for money: Cannot compare Price or benchmark unavailable for some GPUs.
CMP 40HX 8 GB has 8 GB of VRAM, while RTX 3080 Ti has 12 GB, which matters when scenes, textures, or geometry get heavier.
If you are deciding between these cards for Blender, focus first on Blender benchmark score, VRAM capacity, memory bandwidth, and whether your scenes are likely to benefit more from raw speed or extra memory headroom. The comparison table above keeps those tradeoffs in one place.
