11,688
Very fast — handles complex scenes and production renders with ease.
24 GB
Plenty of room for large scenes, dense geometry, and 4K–8K textures.
16,384
Very high core count — excels at heavy parallel rendering workloads.
Ada Lovelace
Current-generation design with efficient ray tracing and strong Cycles throughput.
1,010 GB/s
Very high throughput — keeps up with complex shading and large texture workloads.
2.52 GHz
High clock speed — helps with viewport responsiveness and per-core performance.
OptiX, CUDA
OptiX is typically the fastest option; CUDA provides a reliable fallback.
450 W
High power draw — plan for a strong PSU and good airflow.

Core specs
- 128 RT Cores (3rd Gen)Ray tracingHardware ray tracing support can speed up tasks that rely on realistic light transport, reflections, shadows, and path tracing.
- 512 Tensor Cores (4th Gen)Tensor 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.
Memory specs
- 24 GB GDDR6XMemory 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.
- 384-bit Memory InterfaceMemory 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.
- 21 Gbps Memory SpeedMemory speedFaster memory speed contributes to higher memory bandwidth, which helps the GPU move scene data more quickly. It works together with the memory bus width to determine total bandwidth.
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.
