NVIDIA Launches RTX PRO 4500 Blackwell Server Edition GPU

NVIDIA has added another graphics card to its server lineup, this time in the form of a passively cooled, single-slot RTX PRO 4500 Blackwell Server Edition GPU. The company positions this release as a highly efficient GPU for compute-dense environments. It comes with 10,496 CUDA cores, 82 Ray Tracing cores, and 32 GB of GDDR7 memory running on a 256-bit bus, providing 800 GB/s of memory bandwidth, all within a total graphics power of 165 W. This specification is similar to the current RTX PRO 4500 Blackwell with an active dual-slot cooler but saves a few watts of TGP, as the actively-cooled edition has a 200 W TGP. The difference in TGP is attributed to higher-binned “Blackwell” GB203 dies with better frequency tuning, resulting in a similar performance target for this GPU. This server edition SKU also reduces memory bandwidth, running the 32 GB GDDR7 modules at 25 Gbps effective, while the regular blower-style RTX PRO 4500 Blackwell uses full 28 Gbps modules.

This server edition SKU is designed for server configurations that require hyper-dense setups, where a single-slot solution will be cooled by high-RPM server fans. For example, server farms could install a dozen of these GPUs in parallel within a single system, stacking them as long as there are available PCIe slots. High airflow chassis would push air through the passively cooled GPU shroud, cooling the 165 W TGP. Interestingly, this is not even the most efficient GB203 bin with 10,496 CUDA cores, as NVIDIA offers a GeForce RTX 5090 Mobile GPU SKU with only a 95 W TDP. However, that comes at the cost of some clock speeds, which are still unknown for the newest RTX PRO 4500 Blackwell Server Edition GPU.
