Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 13.3 GB, but this setup only exposes 8.0 GB of usable VRAM.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.

No, Phi 3 Medium 14B requires more memory than Radeon RX 7600M 8GB provides.
Phi 3 Medium 14B (14B parameters) requires approximately 13.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Phi 3 Medium 14B is Q4_K_M, which balances quality and memory efficiency.
On Radeon RX 7600M 8GB, Phi 3 Medium 14B achieves approximately 5.5 tokens per second decode speed with a time-to-first-token of 35139ms using Q4_K_M quantization.
For coding workloads, Phi 3 Medium 14B on Radeon RX 7600M 8GB receives a F grade with 5.5 tok/s and 4K context.
On Radeon RX 7600M 8GB, Phi 3 Medium 14B can safely use up to 4K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
Add more VRAM headroom. The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
