NVIDIA Launches RTX PRO 5500 Blackwell GPU With 84 GB GDDR7 Memory

NVIDIA has announced the RTX PRO 5500, a new Blackwell-architecture GPU featuring 84 GB of GDDR7 memory, targeting professional workstation and AI inference workloads. The large memory footprint makes it particularly suitable for running large language models locally, fine-tuning mid-sized models, and handling high-resolution multimodal inference without offloading to the cloud. For developers who need on-premise AI compute — whether for privacy, latency, or cost reasons — this card represents a significant step up in accessible local AI horsepower. The Blackwell architecture also brings improved FP4 and FP8 tensor core performance, which directly benefits quantized LLM inference throughput. Teams evaluating on-device or on-premise AI infrastructure should place this card in their benchmark pipeline.
