How well does NVIDIA RTX 4500 Ada scale across multiple GPUs?

Risposta

NVIDIA RTX 4500 Ada performance headline: 31.7 FP16 TFLOPS, 23.8 FP32 TFLOPS, 432 GB/s bandwidth, 24 GB VRAM.

Converted into practical benchmarks: model training a 7B-parameter LLM in FP16 with reasonable batch sizes typically saturates compute before bandwidth; real-time serving on the same model is usually bandwidth-bound and tracks the 432 GB/s figure. Diffusion image generation benchmarks sit between the two — compute-heavy steps utilise tensor cores well, while attention blocks still touch bandwidth.
