NVIDIA RTX PRO 4500 Edge Review: 2.7x the L4 in HPE ProLiant DL145 Gen11

The NVIDIA RTX PRO 4500 Blackwell Server Edition is a single-slot, passively cooled 165W card with 32GB of GDDR7 and 800GB/s, built to replace the L4. In an HPE ProLiant DL145 Gen11 it delivers 2.7x the L4's output throughput while raising whole-server draw from about 196W to 301W.

• Median 2.7x the L4 at 8–32 concurrent requests, 3.0–3.2x at 256
• Generation latency of 12–15ms per token versus 35–40ms on the L4
• Server draw rises from 196W to 301W, 1.3–1.4x better per watt
• 32GB and FP4 enable models the L4 cannot run natively
