Can I Run Granite 4.2 30B on NVIDIA GeForce RTX 5060?
作者： Jakub Rusinowski · 最后更新： 2026年9月11日
No. Granite 4.2 30B needs 20.7 GB at 8K context (18.1 GB weights + 2.6 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 5060 has only 8 GB. No quantization we publish closes a gap that size.

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 8 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 NVIDIA GeForce RTX 5060: 8K 20.7 GB ✗ · 32K 26 GB ✗ · 128K 47.4 GB ✗. Past 8K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Either step down to a smaller size in this family, or move to a NVIDIA GeForce RTX 5090 Laptop GPU (24 GB), the card with the least memory we track that holds it.
No compatible GPU? Granite 4.2 30B on 32 GB of system RAM, CPU only: runs comfortably.
