Steam's recommended spec for Stellaris is Nvidia® GeForce™ GTX 560 Ti (1GB VRAM) or AMD® Radeon™ R7 370 (2 GB VRAM) with 4GB RAM and a Intel® iCore™ i5-3570K. That spec was written for the Paradox Interactive team's internal "minimum acceptable" target, not for a buyer in 2026 planning to keep this PC for the next four years.
CPU-bound moments: Stellaris drops frames during specific high-load scenarios more than its average framerate suggests. Invest in CPU single-thread performance — the Ryzen 7800X3D and 9800X3D are particularly strong here.
What you can skip vs what matters
- Worth spending on: GPU first, then a fast NVMe SSD (most modern games benefit from sub-3000MB/s sustained reads), then RAM at the tier amount.
- Worth skipping at this budget: RGB lighting, exotic cooling, brand-name PSUs above 850W (unless you're building enthusiast tier), and motherboards with more than 4 M.2 slots.
- Don't compromise on: The PSU. A reliable 750W gold-rated unit will outlast two GPU upgrades.
Frequently asked questions
- What's the cheapest PC that can run Stellaris?
- A AMD Ryzen 5 7600 + NVIDIA GeForce RTX 4060 8GB build at around £799. That hits 1080p/60 on high settings.
- Is Stellaris CPU-heavy or GPU-heavy?
- Stellaris leans heavily on the CPU — late-game scenarios stress single-thread performance. A modern X3D chip (Ryzen 7 7800X3D / 9800X3D) makes a noticeable difference.
- Do I need ray tracing for Stellaris?
- Stellaris does not require ray tracing. Any current-generation GPU will deliver the intended visual experience.
- How much RAM do I need?
- For Stellaris, 32GB is the sensible answer in 2026. 16GB still works for the budget tier but limits future-proofing.
