NVIDIA Intros RTX PRO 5500 Blackwell Graphics Card, Features Same Core Count As The 5090 But With 2.6x The VRAM - Wccftech
One of the biggest features of the RTX PRO 5500 Blackwell is its VRAM, which is listed at 84 GB. This is 36 GB more than the RTX PRO 5000 Blackwell, 12 GB less than the RTX PRO 6000 Blackwell, and over 2.5x more than the RTX 5090. This puts the RTX PRO 5500 Blackwell slightly above the RTX PRO 5000 in terms of bandwidth, but slower than the 1.792 TB/s bandwidth of the RTX 5090 and the RTX PRO 6000 Blackwell.
NVIDIA's latest addition to the Blackwell PRO family is the RTX PRO 5500 Workstation Edition graphics card with 84 GB of memory.
The NVIDIA RTX PRO "Blackwell" family is one of the most extensive PRO lineups we have seen so far. It features various SKUs, and the latest one is the RTX PRO 5500 Blackwell, which targets the Pro and Workstation segment.
The NVIDIA RTX PRO 5500 Blackwell Workstation Edition accelerates agentic AI, physical simulation, and graphics workloads to teams that need workstation power at scale. Built on the NVIDIA Blackwell architecture and equipped with 84 GB of ultra-fast GDDR7 memory, it’s designed for rack-mounted workstation deployment with a choice of air- or liquid-cooled thermal solutions, letting teams centralize, share, and scale workstation GPU power across the enterprise.
In terms of specifications, the NVIDIA RTX PRO 5500 Blackwell graphics card is based on the GB202 GPU silicon. This is the same GPU that is housed in the flagship RTX PRO 6000 & the GeForce RTX 5090 graphics cards.
The core count is also the same as the RTX 5090, with 21,760 CUDA cores, which are amped up by a 600W TDP. The RTX 5090 features 680 TMUs, 680 Tensor cores, 176 ROPs, and 170 RT cores along with a 96 MB L2 cache. We can't say for sure if all of these specs will remain the same on the RTX PRO 5500. NVIDIA does mention a trio of its 9th Generation NVENC and 6th Generation NVDEC engines on the chip.
One of the biggest features of the RTX PRO 5500 Blackwell is its VRAM, which is listed at 84 GB. This is 36 GB more than the RTX PRO 5000 Blackwell, 12 GB less than the RTX PRO 6000 Blackwell, and over 2.5x more than the RTX 5090. The card supposedly features a 416-bit bus interface, as listed by PNY on the specs page, which is unusual.
If you take a 416-bit bus, that gives us 13 32-bit interfaces. A clamshell design would house 26 DRAM interfaces. With 3 GB DRAM dies, you get 76 GB VRAM, and with 4 GB, you get 104 GB of VRAM. It is likely that NVIDIA is using a mix of different-density VRAM dies to reach 84 GB.
The card does reach a memory bandwidth of up to 1398 GB/s, which means that the memory will be operating at around 27 Gbps speeds. This puts the RTX PRO 5500 Blackwell slightly above the RTX PRO 5000 in terms of bandwidth, but slower than the 1.792 TB/s bandwidth of the RTX 5090 and the RTX PRO 6000 Blackwell.
Additional specs include up to four DP 2.1b outputs, a PCIe Gen5 x16 connector interface, a single CEM5 16-pin connector for power, and support for both air- and liquid-cooled thermal solutions. It also supports MIG (Multi-instance GPU) functionality, which turns one card into two instances with 42 GB of memory each. NVIDIA and its partners aren't listing the prices yet, but we expect it to cost a lot since the RTX PRO 5000 Blackwell 48 GB is listed at around $ 9,200 USD.
