NVIDIA RTX PRO 6000 Blackwell Server Edition vs NVIDIA RTX PRO 4500 Blackwell Server Edition

The RTX PRO 4500 Blackwell is the newer part: Blackwell, launched in 2026, against the RTX PRO 6000 Blackwell's Blackwell from 2025. 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 6000 Blackwell against the RTX PRO 4500 Blackwell: FP32 120 vs 51 TFLOPS, FP16 500 vs 203 TFLOPS, FP8 1,000 vs 406 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.

Memory is 96 GB against 32 GB, fed at 1.6 TB/s versus 800 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.

Power budgets are 600 W for the RTX PRO 6000 Blackwell and 165 W for the RTX PRO 4500 Blackwell. At FP32 that works out to 0.20 against 0.31 TFLOPS per watt.

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.
