A New Professional Powerhouse

Nvidia has officially expanded its professional graphics lineup with the introduction of the RTX Pro 5500. This workstation-focused GPU, powered by the cutting-edge Blackwell architecture, stands out due to its exceptionally large onboard memory capacity of 84 GB of GDDR7, designed to handle demanding professional workloads.


Unique Architectural Design

To accommodate such a vast amount of memory, Nvidia engineers utilized an unconventional physical layout. The card features a "sandwich" configuration where 28 memory chips are distributed across both sides of the printed circuit board: 14 modules are mounted next to the processor, with the remaining 14 on the rear.

The memory subsystem utilizes a 416-bit interface, which is notably distinct from typical industry standards. This setup effectively provides 1,398 GB/s of aggregate bandwidth. According to technical analysis, this configuration utilizes 13 distinct 32-bit memory channels, a rare design choice in modern GPU architecture.


Performance and Positioning

The card is built around the GB202 processor, which boasts 21,760 CUDA cores—matching the count found in the high-end consumer GeForce RTX 5090. However, Nvidia emphasizes that this unit is strictly optimized for professional workstations rather than consumer gaming. The manufacturer has implemented multi-instance partitioning, allowing users to configure the card as either a single 84 GB block or two separate 42 GB segments.


Specifications Overview

  • Architecture: Blackwell
  • Memory: 84 GB GDDR7
  • CUDA Cores: 21,760
  • TDP: 600 W

In terms of hierarchy, the RTX Pro 5500 sits just beneath the flagship RTX Pro 6000, which offers 96 GB of memory and 24,064 CUDA cores. It significantly outperforms the RTX Pro 5000, which is capped at 72 GB and 14,080 CUDA cores.


Deployment and Availability

Designed primarily for enterprise environments and rack-mounted servers, the card requires a significant power supply with a 600 W rating. It will be available in both air-cooled and liquid-cooled versions. Regarding its deployment, Nvidia notes:

«The card is built strictly for rack-mounted workstation deployment rather than desktop towers.»

While official pricing and release dates remain undisclosed, the device is expected to come with a premium price tag, targeting large-scale enterprise users who prioritize memory capacity for massive datasets over pure raw bandwidth.
