Yes, with partial offload (slower). pplx-decider 27B (Perplexity, decision) on RTX 4070 12GB at Q4_K_M uses system RAM (19.3 GB needed, 11.5 GB usable), about 5 tok/s (estimate).
Hardware: RTX 4070 12GB · Model: pplx-decider 27B (Perplexity, decision)
RTX 4070 12GB has 12 GB of VRAM and 504 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 11.5 GB. Partial offload may also use 60% of that system RAM. pplx-decider 27B (Perplexity, decision) (27B, Perplexity) at Q4_K_M is a 17 GB download and needs 19.3 GB with headroom for about 8k tokens.
