  "account": "Nvidia has introduced a new professional graphics card, the RTX Pro 5500, which features a remarkable 84 GB of onboard GDDR7 memory. This workstation graphics card utilizes a unique sandwich configuration, with 14 GDDR7 memory modules positioned both above and below the PCB. Despite the enormous memory capacity, the memory interface operates at a relatively narrow 416-bit width, consisting of 13 separate 32-bit memory channels. The RTX Pro 5500 is powered by a GB202 processor with 21,760 CUDA cores, the same count found in Nvidia's flagship GeForce RTX 5090. The card's power consumption is rated at a hefty 600W, and it is designed strictly for rack-mounted workstation deployment. The RTX Pro 5500 sits just below the RTX Pro 6000 in terms of raw specifications, offering 21,760 CUDA cores and 84 GB of memory compared to the 24,064 CUDA cores and 96 GB of memory on the top-tier card. As the most likely buyers for this card will be enterprise customers, the steep price and power demands are expected.",
