Written by Jakub Rusinowski · Last updated September 29, 2026
No — Laguna XS 2.1 33B-A3B at Q4_K_M needs 22.6 GB at 8K context (19.9 GB weights + 2.7 GB KV cache/overhead), and the AMD Radeon RX 9070 XT's 16 GB leaves it ~6.6 GB short. The cheapest card that runs it is the NVIDIA GeForce RTX 5090 Laptop GPU (24 GB).

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 16 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the AMD Radeon RX 9070 XT: 8K 22.6 GB ✗ · 32K 28.1 GB ✗ · 128K 50.3 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
