3,125
Entry-level speed — fine for learning and lighter scenes.
16 GB
Comfortable for most production work and complex asset sets.
6,144
Solid core count for most Blender rendering tasks.
Ampere
Previous-generation design — still competitive, especially at higher VRAM tiers.
448 GB/s
Moderate bandwidth — sufficient for standard rendering workloads.
1560 MHz
Lower clock speed — typical of older or workstation-class GPUs.
OptiX, CUDA
OptiX is typically the fastest option; CUDA provides a reliable fallback.
140 W
Low power — easy to cool and efficient for smaller builds.

Core specs
- Tensor cores: 192Tensor coresIn Blender, tensor cores primarily accelerate the OptiX AI denoiser, which can clean up noisy renders much faster than traditional denoising. They also help with AI-powered features like DLSS in the viewport.
- RT cores: 48Ray tracingHardware ray tracing support can speed up tasks that rely on realistic light transport, reflections, shadows, and path tracing.
- Base clock: 735 MHzBase clockIt is useful as a baseline specification, but real Blender performance depends on the full GPU design, not just the base clock number.
- Process size: 8 nmProcess nodeSmaller process nodes can improve efficiency and density, but they are not a direct performance score. They are best read as part of the overall architecture story.
Memory specs
- Memory type: GDDR6Memory typeYou will often see names like GDDR6 or GDDR6X. In practice, memory type matters less on its own than overall memory bandwidth and total VRAM.
- Memory bus: 256-bitMemory busA wider bus can move more data at once, but real performance also depends on memory speed and architecture. Bus width alone does not tell the full story.
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.
