Blender uses both CPU and GPU for rendering. System RAM matters hugely for scene complexity, sculpting, and simulation. A typical production scene can consume 32-64GB of system RAM.
Priority Upgrades
| Upgrade | Impact | Cost* |
|---|---|---|
| RAM: 32GB → 64GB DDR5 | Larger scenes, more sculpt detail | ~£130 |
| SSD: 2-4TB NVMe Gen 4 | Faster saves, texture streaming | ~£200 |
RAM vs VRAM
GPU rendering is limited by VRAM. System RAM lets you work with complex scenes in the viewport. For Cycles, consider an RTX 4070 Ti (12GB) or RTX 4090 (24GB) for GPU rendering without compromises.
Frequently Asked Questions
Is 32GB enough for Blender?
For hobby work yes. Production scenes with detailed sculpts need 64GB.
Does RAM speed matter for rendering?
CPU rendering sees 3-8% improvement. GPU rendering depends on VRAM, not system RAM speed.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
