Granite 4.0 H Small 32B-A9B on RTX 4070 SUPER Q4_K_M
too tight
On an RTX 4070 SUPER (12 GB), Granite 4.0 H Small 32B-A9B in Q4_K_M needs about 19,9 Go of video memory: too tight, part of the model would have to be offloaded to system memory (much slower).

No speed estimate: the model does not fit in video memory, part of it would spill into system memory and speed would collapse (often below 5 tok/s).

Estimated VRAM = file + KV cache (full-attention layers, f16) + ~0,5 Go of buffers, excluding memory used by the system — hence the slightly higher “recommended VRAM”, which keeps that margin. Speed ≈ estimated speed × weights read ÷ (weights read + added KV cache).
Estimates based on real measurements of other models on this card and on the model's public data (IBM Granite). As soon as a measurement exists, this page shows the real figures.
