Best local LLMs for the RTX A4000 Laptop

⚠ Laptop part — mobile clocks and thermals run below desktop sibling speeds; treat the band as optimistic for sustained load.

Speed

computed band 34.0-57.0 tok/s for 8B Q4_K_M (roofline, 384 GB/s VRAM)

Effective decode window: 0.46–0.76 of 384 GB/s nominal → ~177–292 GB/s effective (llama.cpp decode, Q4_K_M basis; arch window, community-calibrated)

What fits (computed)

→ 13b-q4 no 14.6 GB vs 8 GB usable — does not fit

→ 3b-q4 full 2.8 GB needed of 8 GB usable — headroom for context

→ 4b-q4 full 3.7 GB needed of 8 GB usable — headroom for context

→ 8b-q4 full 6.1 GB needed of 8 GB usable — headroom for context

Gotchas

⚠ 8 GB GDDR6 @ 12 Gbps on a 256-bit bus = 384 GB/s (TPU RTX A4000 Mobile) — the '12 GB / 448 GB/s' desktop A4000 is a different card; the 12 GB coverage hint was wrong

⚠ Essentially an RTX 3080 Laptop with 8 GB and pro drivers (GA104, 5120 CUDA, 160 3rd-gen Tensor cores)

⚠ Alias RTX A3000 Laptop = 6 GB sibling; alias RTX A5500 Laptop = 16 GB higher card — verify actual VRAM before quoting

⚠ 8 GB is the practical ceiling: 13B-class Q4 fits, anything larger spills to shared memory and crawls
