Best PCs for video editing with After Effects in 2026 Multi-core CPU and plenty of RAM for compositing and complex renders
After Effects is a CPU-first application: final renders use every available core, and RAM determines how many frames are cached in memory for real-time preview. The GPU speeds up previews with CUDA, but it does not affect the final render. With After Effects, more RAM always means smoother playback.

Recommended computers for After Effects
A high-performance multi-core CPU + plenty of RAM: the two factors with the biggest impact on After Effects speed.
Multi-core CPU for fast renders and 64 GB of RAM for frame caching
GPU
NVIDIA GeForce RTX 5070 (12 GB VRAM)
CPU
AMD Ryzen 9 9950X
The 16-core Ryzen 9 9950X is the right choice for After Effects: multithreaded renders scale directly with core count. The RTX 5070 enables GPU Acceleration for fast previews. With 64 GB of RAM, the frame cache allows real-time preview of complex compositions without rebuffering.

GPU
NVIDIA GeForce RTX 5080 (16 GB VRAM)
CPU
AMD Ryzen 9 9950X
The RTX 5080 matters if you use plugins such as Element 3D, Video Copilot or complex particle effects that take advantage of VRAM. For Mocha renders and stabilization, the extra VRAM removes any GPU memory limitation. Paired with the Ryzen 9 9950X, it is the benchmark for unlimited production.

Frequently asked questions
How much RAM does After Effects need?
After Effects reserves RAM to cache rendered frames. With 32 GB it can preview moderate projects. With 64 GB, complex 4K compositions preview in real time without rebuffering. 64 GB is the standard for professional production with AE.
GPU or CPU: which matters more in After Effects?
The CPU matters more. After Effects final renders are fully multithreaded and scale with CPU cores. The GPU speeds up previews (with GPU Acceleration enabled), but the final render — the one that matters for exporting — depends on the CPU.
AMD or NVIDIA for After Effects?
NVIDIA is preferable thanks to CUDA acceleration for previews and compatibility with plugins such as Element 3D. AMD works fine, but some effects and third-party plugins have no GPU acceleration on OpenCL.
