Offload
30%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 20% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.6 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Inference speed
Estimated decode speed (tokens/sec) for Neural Chat 7B at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~98 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Yes, RTX 4050 Laptop 6GB can run Neural Chat 7B at Q3_K_S quantization (Very compromised (needs ~0.6 GB host RAM)). The recommended Q4_K_M requires 8.0 GB which exceeds available memory, but at Q3_K_S it needs only 7.2 GB. Expected decode speed: 21.0 tok/s.
Neural Chat 7B (7B parameters) requires approximately 8.0 GB at Q4_K_M quantization. On RTX 4050 Laptop 6GB, it fits at Q3_K_S using 7.2 GB.
The recommended quantization is Q4_K_M, but on RTX 4050 Laptop 6GB the best fitting quantization is Q3_K_S, which uses 7.2 GB.
On RTX 4050 Laptop 6GB, Neural Chat 7B achieves approximately 21.0 tokens per second decode speed with a time-to-first-token of 9229ms using Q3_K_S quantization.
For coding workloads, Neural Chat 7B on RTX 4050 Laptop 6GB receives a F grade with 14.4 tok/s and 4K context.
On RTX 4050 Laptop 6GB, Neural Chat 7B can safely use up to 6K tokens of context at Q3_K_S quantization. The model's official context limit is 8K, but available memory constrains the safe maximum.
