Tensor core performance of NVIDIA RTX A4000

Válasz

NVIDIA RTX A4000 is a Ampere card offering 19.2 FP16 TFLOPS and 16 FP32 TFLOPS alongside 448 GB/s of memory bandwidth. That's enough compute to handle modern model training and real-time serving workloads at serious scale.

Benchmarks show NVIDIA RTX A4000 performs particularly well on transformer-style models where tensor cores are saturated by large MatMuls. Diffusion models, speech, and vision workloads also see strong speedups versus older generations. For latency-sensitive production real-time serving, NVIDIA RTX A4000 usually hits target token-per-second rates on large language models well above the 30-50 tok/s threshold most products aim for.
