FAQ
How many local LLMs can the RTX 4090 run?
28 of the 63 open-weight models in this directory fit, with 24 GB of VRAM, by this site's rule of thumb that the smallest non-MLX download is at most 85% of the memory. MLX builds do not count here: they run on Apple silicon only.
Can the RTX 4090 run Cohere Aya Expanse 32B?
Yes, by this directory's rule of thumb: its smallest non-MLX download, 19.8 GB, is at most 85% of 24 GB (20.4 GB), the Q4_K_M GGUF build from bartowski/aya-expanse-32b-GGUF. That leaves room for the context. It is a memory check, not a speed estimate.
Can the RTX 4090 run Liquid AI LFM2.5-24B-A2B?
Yes, by this directory's rule of thumb: its smallest non-MLX download, 14.5 GB, is at most 85% of 24 GB (20.4 GB), the Q4_K_M GGUF build from LiquidAI/LFM2.5-24B-A2B-GGUF. That leaves room for the context. It is a memory check, not a speed estimate.
Can the RTX 4090 run NVIDIA Nemotron 3.5 Bolt 74B-A9B?
Not by this directory's rule of thumb: its smallest non-MLX download, 22.0 GB, is more than 85% of 24 GB (20.4 GB). It needs the 32 GB tier or more: https://www.developersdigest.tech/local-models/fits/32.
Can the RTX 4090 use system RAM for bigger models?
This page only counts models that fit entirely in the 24 GB of VRAM. Runtimes can offload layers to system RAM, but this directory does not list or measure that.
What memory bandwidth does the RTX 4090 have?
NVIDIA states 1,008 GB/s of memory bandwidth (GDDR6X). From the spec notes: 384-bit memory interface; the 4090 page does not list bandwidth, so the 1008 GB/sec figure comes from the Compare to Previous table on NVIDIA's RTX 5090 page. This page does not turn bandwidth into a speed estimate.
