How well does NVIDIA GeForce RTX 4070 Ti scale across multiple GPUs?

Sagot

NVIDIA GeForce RTX 4070 Ti performance headline: 40.1 FP16 TFLOPS, 20 FP32 TFLOPS, 504 GB/s bandwidth, 12 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 504 GB/s figure. Diffusion image generation benchmarks sit between the two — compute-heavy steps utilise tensor cores well, while attention blocks still touch bandwidth.
