HOW TO CHOOSE
RTX PRO 4000 vs RTX PRO 4500
Same Blackwell generation, one step up: 32 GB and 896 GB/s at 200 W, but dual-slot. When the model fits in 24 GB, the 4000's single-slot density wins; when it does not, the 4500 is the smallest Blackwell that works.
RTX PRO 4500 vs RTX PRO 4000
Same generation, different shape: the 4500 adds 8 GB, 224 GB/s more bandwidth, and 60 W more power, but costs you the second slot. Pick the 4000 for density, the 4500 when 24 GB is not enough.
Workload fit
RTX PRO 4000: dense inference nodes, local llm and gen-ai development, rendering and medical imaging. RTX PRO 4500: mid-size llm inference and fine-tuning, data science and simulation, rendering and content creation.
