AI workloads are GPU-bound, and VRAM is everything. A 12GB GPU that handles gaming fine will choke on a 7B parameter model. Here's what actually matters for local AI work.
VRAM requirements cheat sheet
| Task | Min VRAM | Recommended |
|---|---|---|
| Stable Diffusion (image gen) | 8GB | 12GB+ |
| LLM 7B params (Llama, Mistral) | 8GB | 12GB+ |
| LLM 13B params | 16GB | 24GB |
| LLM 70B params | 48GB (multi-GPU) | 96GB+ |
| Video generation (Runway, etc.) | 12GB | 24GB+ |
GPU picks for AI in 2026
- Budget (8GB): RTX 4060 Ti 8GB - handles Stable Diffusion, small LLMs. Not ideal for serious work.
- Sweet spot (16GB): RTX 5060 Ti 16GB - best value for AI work in UAE. Runs 7B models comfortably.
- Pro (24GB): RTX 4090 24GB - the AI workhorse. Runs 13B models, fast Stable Diffusion. Used prices dropping.
- Flagship (32GB): RTX 5090 32GB - overkill for most, but handles 30B+ models with quantization.

Memory is the line to look at twice. This build calls for 64GB because local models are memory-hungry, and a 64GB DDR5 6000 kit now runs close to 5,900 AED - see our coverage of the DRAM price climb. That is nearly half the build. If you are running quantised models that fit in VRAM, 32GB saves you roughly 4,000 AED and costs you very little in practice; go to 64GB only if you genuinely load large models into system memory.
Why RAM matters for AI
AI models are loaded into VRAM first, then overflow into system RAM. If you have 16GB VRAM and 16GB RAM, a 13B model that needs 20GB total will crash. With 64GB RAM, it can offload to system memory and still work (slower, but functional). For serious AI work, 64GB RAM is the minimum.
