Nvidia's RTX Pro 5500: 84GB VRAM Powerhouse
18 Sep
Summary
- Nvidia's new RTX Pro 5500 boasts 84GB of GDDR7 memory.
- The card uses a double-sided design with 28 memory chips.
- This professional card prioritizes memory capacity over bandwidth.
Nvidia has introduced the RTX Pro 5500, a professional workstation graphics card equipped with a substantial 84GB of GDDR7 memory. This new card is built on Blackwell architecture and features 21,760 CUDA cores, matching the GeForce RTX 5090's core count.
To achieve its massive memory capacity, Nvidia employed an innovative double-sided layout. Fourteen GDDR7 memory modules are placed on the front of the circuit board, with another fourteen on the rear. This 'sandwich' configuration allows for 28 chips to be integrated onto a single card. Each chip operates at approximately 27 Gbps per pin, contributing to an aggregate bandwidth of about 1,398 GB/s via a 416-bit interface.
The RTX Pro 5500 is strictly designed for professional workstation duties. It can be partitioned into either a single 84GB block or two separate 42GB segments. The card has a significant 600W power draw and is intended for rack-mounted workstations, available in both air-cooled and liquid-cooled variants.
Positioned within Nvidia's workstation lineup, the RTX Pro 5500 falls just below the flagship RTX Pro 6000. While the Pro 6000 offers more CUDA cores and 96GB of memory, the Pro 5500 significantly surpasses the RTX Pro 5000's specifications. Nvidia appears to be emphasizing memory volume for handling large datasets, a trade-off that will depend on specific professional application needs.
