Yes. Laya 421M (Convai, decision) fits in fast memory on RX 7900 XTX 24GB at BF16 (1.5 GB needed, 23.5 GB usable), about 686 tok/s (estimate).
Hardware: RX 7900 XTX 24GB · Model: Laya 421M (Convai, decision)
RX 7900 XTX 24GB has 24 GB of VRAM and 960 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 23.5 GB. Partial offload may also use 60% of that system RAM. Laya 421M (Convai, decision) (0.421B, Convai Innovations) at BF16 is a 0.84 GB download and needs 1.5 GB with headroom for about 8k tokens.
