Nvidia RTX PRO 5500 Blackwell Debuts With 84GB VRAM for Enterprise AI Workloads

Nvidia Expands Blackwell Lineup With High-Memory Workstation Card

Nvidia has launched the RTX PRO 5500 Blackwell, a workstation graphics card built on the Blackwell architecture that mirrors the core configuration of the consumer GeForce RTX 5090 while dramatically expanding memory capacity. The professional graphics card carries 21760 CUDA cores matched with 84GB GDDR7 memory, delivering 2.6 times more VRAM than the 32GB found on the RTX 50901

. This memory expansion targets large-model inference, rendering, and dataset-heavy workloads that exceed consumer VRAM ceilings, positioning the card squarely in enterprise workstation segments where memory capacity often determines project feasibility.

GB202 Silicon Powers Professional and Consumer Tiers

The RTX PRO 5500 Blackwell uses the same GB202 GPU silicon found in both the flagship RTX PRO 6000 and the consumer GeForce RTX 50902

. This strategy continues Nvidia's pattern of mirroring GeForce Blackwell dies into the RTX PRO workstation stack with substantially expanded memory pools, allowing the company to serve professional visualization, AI and high-performance computing markets without requiring separate architecture development1

. The card operates at a 600W TDP and includes three 9th Generation NVENC and 6th Generation NVDEC engines2

Unusual Memory Configuration Raises Technical Questions

PNY's specifications list a 416-bit bus interface for the RTX PRO 5500 Blackwell, an unconventional configuration that suggests mixed-density VRAM dies2

. A 416-bit bus provides 13 32-bit interfaces, which in a clamshell design would house 26 DRAM interfaces. With 3GB DRAM dies, this yields 78GB VRAM, while 4GB dies produce 104GB, indicating Nvidia likely uses different-density modules to reach the 84GB target. The card achieves memory bandwidth of 1398 GB/s at approximately 27 Gbps speeds, placing it above the RTX PRO 5000 but below the 1.792 TB/s bandwidth of the RTX 5090 and RTX PRO 6000 Blackwell2

Deployment Options Target Rack-Mounted Enterprise Infrastructure

The Nvidia RTX PRO 5500 will be offered in both actively air-cooled and liquid-cooled variants, reflecting the power and thermal envelope typical of Blackwell-generation professional silicon at this core count1

. Nvidia describes the card as designed for rack-mounted workstation deployment, allowing teams to centralize, share, and scale workstation GPU power across enterprises2

2

. The card supports Multi-instance GPU functionality, turning one card into two instances with 42GB of memory each, enabling resource partitioning for different workloads or users2

2

. Additional specifications include up to four DisplayPort 2.1b outputs, PCIe Gen5 x16 connector interface, and a single CEM5 16-pin connector for power2

Market Positioning Amid Supply Constraints and Growing Demand

The 84GB capacity places the RTX PRO 5500 Blackwell well above typical consumer cards and into territory more commonly associated with data-center GPUs, though it retains a workstation form factor and driver stack—Nvidia RTX Enterprise drivers—rather than the data-center Hopper/Blackwell HGX ecosystem1

1

. The timing arrives against continued reporting on tight GDDR7 and general DRAM supply through 2026, meaning a workstation SKU carrying 84GB of premium memory faces elevated component costs across the industry1

1

. Demand for high-VRAM single-GPU solutions for local large-language-model inference continues growing among developers and small studios seeking to avoid multi-GPU orchestration overhead1

.

Nvidia has not disclosed pricing or availability windows. Given historical RTX PRO pricing structure, cards in this VRAM and core-count class typically carry premiums several times their GeForce counterparts, reflecting both memory bill of materials and professional software certification bundled with RTX PRO hardware1

1

. The RTX PRO 5000 Blackwell with 48GB is listed at approximately $9,200 USD, suggesting the 5500 will command significantly higher pricing2

2

. Watch for independent benchmarks confirming sustained clocks under the card's cooling solution and real-world throughput in mixed rendering and physical simulation workloads compared to both the consumer RTX 5090 and Nvidia's data-center Blackwell accelerators.
