Nvidia Unveils RTX PRO 5500 Blackwell: 84GB GDDR7, 21,760 CUDA Cores, and 600W TDP

Nvidia is ramping up its Blackwell rollout with the formal unveiling of the RTX PRO 5500 Workstation Edition. Engineered specifically for agentic AI workloads, massive 3D simulation environments, and dense compute pipelines, this workstation powerhouse brings top-tier silicon into enterprise desks.

Technical Specifications & Benchmark Comparison: RTX PRO 5500 vs RTX 5090
To contextualize the raw compute of this new release, here is how the RTX PRO 5500 stacks up against the upcoming consumer flagship (GeForce RTX 5090) and adjacent professional Blackwell GPUs:
| Specification | Nvidia RTX PRO 5500 | GeForce RTX 5090 (Est.) | Nvidia RTX PRO 5000 |
|---|---|---|---|
| Architecture | Blackwell (GB202) | Blackwell (GB202) | Blackwell (GB203) |
| CUDA Cores | 21,760 | 21,760 | 12,800 |
| VRAM Capacity | 84GB GDDR7 ECC | 32GB GDDR7 | 48GB GDDR7 ECC |
| Memory Bus | 448-bit | 512-bit / 448-bit | 256-bit |
| Memory Bandwidth | 1,398 GB/s | ~1,792 GB/s | ~896 GB/s |
| TDP / Power Draw | 600 W | 600 W | 300 W |
| Display Connectivity | 4x DisplayPort 2.1b (16K / 8K 240Hz) | DisplayPort 2.1b + HDMI 2.1 | 4x DisplayPort 2.1b |
| Multi-Instance GPU (MIG) | Yes (2 isolated instances) | No | Yes |
The Enterprise Counterpart to the GeForce RTX 5090
Hardware aficionados will quickly spot the active silicon overlap with consumer flagships. Utilizing 21,760 active CUDA cores, the RTX PRO 5500 operates the identical core matrix anticipated on the consumer GeForce RTX 5090. The pivotal divergence is memory architecture.
Where consumer GPUs will top out at 32GB of GDDR7, this workstation release packs a massive 84GB GDDR7 buffer with ECC reliability. That expansive frame buffer is purpose-built to hold 70B+ parameter quantized AI models in local VRAM or render uncompressed multi-million polygon assets in Unreal Engine 5 without system memory throttling.
The card also brings Multi-Instance GPU (MIG) partition capabilities, allowing IT managers to segment the GPU into two fully sandboxed environments for multi-user workstation virtualization.
600W Power Envelope and Thermal Solutions
With an intensive 600-watt TDP, proper heat dissipation is essential. Nvidia has certified two thermal implementations: a dual-slot blower configuration for workstation towers and high-efficiency cold-plate liquid cooling options for high-density 4U rack-mount chassis.
At such a demanding thermal and power threshold, power supply headroom and operational electricity costs become decisive factors. A workstation loaded with an RTX PRO 5500 and a high-performance host CPU will easily draw 900 to 1,000+ real watts at the wall under sustained compute workloads.
