What actually differs
Both GPUs launched in 2024: the Wormhole n300s on Wormhole and the Wormhole n150s on Wormhole.
Dense throughput for the Wormhole n300s against the Wormhole n150s: FP16 131 vs 74 TFLOPS, FP8 466 vs 262 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 24 GB against 12 GB, fed at 576 GB/s versus 288 GB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
