KeyShot System Requirements and Workstation PC Optimization
Optimizing Performance for KeyShot with a Workstation PC
KeyShot is an industry-leading real-time rendering and animation software, widely used in product design, architecture, engineering, and marketing visualization. Unlike traditional rendering solutions, KeyShot offers both CPU-based ray tracing and GPU-accelerated rendering, allowing users to choose the best approach for their workflow. However, achieving fast rendering speeds, smooth model manipulation, and optimal efficiency requires a high-performance workstation PC with carefully selected hardware.
Like most software developers, Luxion provides a list of minimum and recommended system requirements for KeyShot, but these lists only cover the basics needed to run the software, not the ideal configurations for professional users. Additionally, system requirements can sometimes be outdated or suboptimal, failing to account for the latest advancements in multi-core processors, GPU acceleration, and high-speed storage solutions. That’s why we at Workstation PC conduct our own in-depth hardware testing and benchmarking to determine the best components for KeyShot. Whether you prefer CPU or GPU rendering, our custom-built KeyShot workstations are designed to maximize performance, minimize rendering times, and enhance overall workflow efficiency.
CPU vs. GPU Rendering in KeyShot
Should You Use CPU or GPU Rendering in KeyShot?
For years, KeyShot was strictly a CPU-based rendering engine, meaning that multi-core processors were the primary factor in rendering speed. However, with recent updates, KeyShot has introduced GPU rendering support, allowing users to take advantage of powerful NVIDIA graphics cards for accelerated performance.
- CPU Rendering:
- GPU Rendering:
Which Rendering Mode Should You Choose?
- If you work with extremely large, high-detail scenes, CPU rendering is often the best option due to higher system RAM availability.
- If you need the fastest rendering speeds, GPU rendering is ideal, especially with multiple NVIDIA RTX GPUs.
- Some users prefer a hybrid approach, utilizing both CPU and GPU rendering based on project requirements.
Processor (CPU) Recommendations for KeyShot
What Type of CPU Does KeyShot Need?
The best CPU for KeyShot depends on whether you are using CPU or GPU rendering:
- For CPU rendering: A high-core-count processor with strong multi-threading performance is essential. KeyShot scales almost perfectly with core count and clock speed, so workstations with 32-core or higher CPUs provide the best performance.
- For GPU rendering: CPU performance is less critical, but you still need a strong, high-frequency processor to handle scene preparation and manage multiple GPUs efficiently.
Best CPUs for KeyShot Rendering
For CPU Rendering:
- AMD Threadripper PRO 7995WX (96 Cores, 192 Threads) – The ultimate CPU for CPU-based rendering, offering the highest core count and performance.
- AMD Threadripper 7980X (64 Cores, 128 Threads) – A more affordable but still incredibly powerful option, delivering 80% of the 7995WX’s performance at a significantly lower cost.
For GPU Rendering and 3D Modeling Workflows:
- Intel Core Ultra 9 285K (24 Cores, High Clock Speed) – Ideal for GPU-focused workflows, offering high single-threaded performance for scene preparation, modeling, and animation.
- AMD Ryzen 9 9950X (16 Cores, 32 Threads) – A solid alternative with strong multi-threaded performance, balancing CPU and GPU tasks efficiently.
Does KeyShot Work Better with Intel or AMD CPUs?
- AMD dominates CPU-based rendering with Threadripper PRO processors due to higher core counts and quad-channel memory support.
- Intel processors offer better single-threaded performance, making them ideal for GPU rendering workstations and hybrid workflows.
Video Card (GPU) Recommendations for KeyShot
How Does KeyShot Utilize Video Cards?
KeyShot supports GPU rendering through NVIDIA RTX graphics cards, utilizing CUDA and OptiX acceleration. If you are using GPU rendering, the GPU is the most important component, determining rendering speed, real-time viewport performance, and texture handling capabilities.
Best GPUs for KeyShot GPU Rendering
- NVIDIA GeForce RTX 5090 (32GB VRAM) – The best overall GPU for KeyShot, delivering exceptional speed and memory capacity.
- NVIDIA RTX 6000 Ada (48GB VRAM) – A professional-grade GPU with ECC memory and superior multi-GPU scaling, ideal for large-scale projects and advanced production environments.
- NVIDIA GeForce RTX 5080 (16GB VRAM) – A cost-effective option for professionals who need GPU acceleration without extreme VRAM demands.
Does KeyShot Support Multiple GPUs?
Yes! KeyShot scales almost perfectly with multiple GPUs, meaning two GPUs will cut render times in half, three GPUs will cut it by two-thirds, etc. If you work with high-resolution renders, complex materials, or VR applications, a multi-GPU workstation is highly recommended.
Should You Use a Professional GPU for KeyShot?
- For most users, GeForce RTX cards are the best choice due to their high performance and lower cost.
- For enterprise users, the NVIDIA RTX 6000 Ada provides higher VRAM and better multi-GPU support for large-scale scenes.
Memory (RAM) Recommendations for KeyShot
How Much RAM Does KeyShot Need?
- 32GB – Minimum for most users.
- 64GB – Ideal for complex projects, high-poly models, and large textures.
- 128GB+ – Required for CPU rendering of massive scenes or working with 8K+ textures.
If you plan to use CPU rendering, more RAM is critical because the CPU relies on system memory instead of GPU VRAM.
Storage Recommendations for KeyShot
What is the Best Drive Setup for KeyShot?
- Primary Drive (OS & Applications) – 1TB NVMe SSD for fast boot and load times.
- Project Drive – 2TB NVMe SSD for active projects and KeyShot cache files.
- Storage & Backup Drive – High-capacity SATA SSD or HDD for archiving finished renders and assets.
For optimal performance, separating the OS, project files, and backups across multiple drives ensures faster access speeds and better system stability.
Conclusion
KeyShot’s real-time rendering capabilities demand a workstation optimized for either CPU or GPU rendering. A high-core-count CPU like Threadripper PRO is ideal for CPU rendering, while NVIDIA RTX GPUs provide unmatched performance for GPU-based workflows.
