Best PCs for video editing with Topaz Video AI in 2026 NVIDIA CUDA is a must for AI upscaling and frame interpolation
Topaz Video AI is an AI-powered video processing application that needs NVIDIA CUDA to run at an acceptable speed. Without an NVIDIA GPU, processing runs on the CPU and can take hours instead of minutes. VRAM determines the maximum video size you can process without out-of-memory errors.

Recommended computers for Topaz Video AI
An NVIDIA GPU with CUDA: the one factor that determines AI processing speed in Topaz Video AI.
4K upscaling in a reasonable time with CUDA and enough VRAM
GPU
NVIDIA GeForce RTX 5070 (12 GB VRAM)
CPU
AMD Ryzen 7 9700X
The RTX 5070 enables CUDA for all of Topaz’s AI models — Iris, Apollo, Proteus and Gaia. With 12 GB of VRAM it processes 4K videos without memory errors. Upscaling a 10-minute 1080p video to 4K takes roughly 15-30 minutes instead of hours on the CPU.

GPU
NVIDIA GeForce RTX 5080 (16 GB VRAM)
CPU
AMD Ryzen 9 9950X
The RTX 5080 cuts processing times by up to 60% compared with the RTX 5070 in Topaz Video AI. With 16 GB of VRAM, it processes 4K RAW and 8K videos without memory limitations. The Ryzen 9 9950X and 64 GB of RAM matter if you process many queued files or run other programs at the same time.

Frequently asked questions
Does Topaz Video AI work without an NVIDIA GPU?
Technically yes, but in CPU mode, which is 10 to 20 times slower. A 5-minute video that takes 10 minutes with an RTX 5070 can take more than 3 hours on the CPU. For practical use, an NVIDIA GPU with CUDA is a must.
Does AMD work with Topaz Video AI?
Topaz Video AI has experimental AMD support via DirectML, but performance is significantly lower than with NVIDIA CUDA. In 2026, if Topaz Video AI is your main use case, NVIDIA is the only choice that makes sense.
How much VRAM does Topaz Video AI need?
For 1080p videos: 6-8 GB is enough. For 4K videos: 10-12 GB avoids memory errors. For 4K RAW videos or multiple queued jobs: 16 GB is recommended. With less VRAM than needed, Topaz may crash or process in chunks, increasing the total time.
