Phi-4 (14B) on the NVIDIA GeForce RTX 4060: VRAM by quantization

Assumes a 4K-token context with an f16 KV cache. 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 4060: 8K 10.9 GB ✗ · 16K 12.6 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.
No compatible GPU? Phi-4 (14B) on 16 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every Phi-4 Family variant requires more VRAM than the NVIDIA GeForce RTX 4060 provides (8 GB).
Nearest GPU That Fits
