NVIDIA has introduced the passively cooled, single-slot RTX PRO 4500 Blackwell Server Edition for compute-dense server deployments. 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.
The configuration is similar to the current RTX PRO 4500 Blackwell with an active dual-slot cooler, but it lowers power use, as the actively-cooled edition has a 200 W TGP. NVIDIA attributes the difference in TGP to higher-binned ‘Blackwell’ GB203 dies with better frequency tuning, while targeting similar performance. 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.
The design is intended for server configurations that require hyper-dense setups, where a single-slot solution is cooled by high-RPM server fans. 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.
NVIDIA also indicates that this is not the most efficient GB203 bin with 10,496 CUDA cores, noting that the GeForce RTX 5090 Mobile GPU SKU has only a 95 W TDP. That lower power envelope comes with trade-offs in clock speeds, and clock details for the RTX PRO 4500 Blackwell Server Edition remain undisclosed.
