Nvidia unveiled the single-board server accelerator RTX Pro 4500 Blackwell Server Edition, designed for AI applications and other computational tasks

NVIDIA – New Server Graphics RTX Pro 4500 Blackwell

Below is a recap of the official announcement about the release of the server version of the RTX Pro 4500 Blackwell graphics card, aimed at data centers and cloud services. The text preserves the facts exactly but is formatted more readably.

Key differences
1. Form factor and cooling

The server version occupies only one PCIe slot and uses passive cooling. This makes it more compact and reduces heat output.

2. Power consumption

Passive cooling allows the power draw to be reduced from 200 W to 165 W, which is important for large‑scale deployment in data centers.

3. Memory and bandwidth

To save space and power, the memory clock is lowered to 3 125 MHz, resulting in a reduction of total bandwidth from 896 GB/s to 800 GB/s.

4. External connectors

Unlike the workstation version, the server card does not have video outputs because graphics are used only for computation and remote access in data centers.

Target use
NVIDIA positions the RTX Pro 4500 Blackwell Server Edition as a compact, energy‑efficient alternative to the standard model. It retains the same GPU cores and memory size but removes video outputs and slightly reduces memory bandwidth in favor of passive cooling and lower power consumption. This makes the card ideal for rack servers and cloud platforms where scalability and energy savings are critical.

Bottom line:

The server version of the RTX Pro 4500 Blackwell offers the same computational capabilities in a more compact, energy‑efficient form without external ports—an optimal choice for data centers and cloud solutions.
