System Requirements for Amira-Avizo 3D 2025.1.2

Supported Operating Systems

• Microsoft Windows 10/11 (64-bit)

• Linux x86_64 (64-bit) – Ubuntu 20.04 (64-bit PC desktop image)

GPU Recommendations

The GPU is the single most important component for Amira-Avizo performance. These applications are highly parallelized and benefit significantly from GPU acceleration.

Tip: For mission-critical medical or industrial environments, certified workstation GPUs (Quadro/RTX A-Series) are strongly recommended for maximum stability.

RAM Requirements

Memory requirements depend heavily on dataset size. Allocate 6-8× the dataset size in RAM for optimal performance.

Note: Basic operations typically require 2-3× the data’s memory footprint. Complex workflows may require 6-8× the data size.

CPU Specifications

• Optimal configuration: 8 high-frequency cores (Intel Core i9, AMD Ryzen 9, or AMD Threadripper Pro)

• Performance scaling: Up to 8 cores show near-linear scalability; additional cores provide diminishing returns

• Cache size and clock speed become more important beyond 8 cores

Storage Requirements

Network considerations: Reading data across a network is significantly slower than local disk access. For optimal performance, create local copies of active datasets.
