NVIDIA RTX PRO 4500 Blackwell 32GB vs NVIDIA GB200 Grace Blackwell Superchip 372GB

The RTX PRO 4500 Blackwell is the newer part: Blackwell, launched in 2025, against the GB200's Blackwell from 2024. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.

Dense throughput for the RTX PRO 4500 Blackwell against the GB200: FP32 51 vs 160 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 32 GB against 372 GB, fed at 896 GB/s versus 16.0 TB/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.
