Yes. Granite 4.1 8B needs 4.8 GB at Q4_K_M and the NVIDIA GeForce RTX 4070 Super has 12 GB, leaving about 7.2 GB of headroom, at roughly 72 tok/s (estimated) with room for up to 32K of context.

Assumes a 4K-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 12 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 4070 Super: 8K 6.8 GB · 32K 10.2 GB · 128K 23.9 GB ✗. Past 128K it no longer fits 12 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
No compatible GPU? Granite 4.1 8B on 16 GB of system RAM, CPU only: runs.
