Radeon PRO W7800 vs RTX PRO 4500 Blackwell: In-Depth Breakdown
Inference Speed: Memory Bandwidth
Memory bandwidth determines how quickly data is fed to the compute units — it's the main bottleneck for autoregressive inference (token generation in LLMs). The RTX PRO 4500 Blackwell delivers 896 GB/s versus 576 GB/s on the Radeon PRO W7800, a 56% edge. For models already loaded into VRAM, token generation speed scales closely with this number: the RTX PRO 4500 Blackwell will produce tokens proportionally faster in bandwidth-bound workloads.
AI Training & Compute
For model training, scientific simulation, and rendering, FP32 throughput is the key metric. The RTX PRO 4500 Blackwell delivers 53.8 TFLOPS against 45.2 TFLOPS for the Radeon PRO W7800 — a 19% compute advantage. Training runs and heavy matrix operations will complete proportionally faster on the RTX PRO 4500 Blackwell.
Price & Value
The Radeon PRO W7800 lists from $2,256 EUR, $1,218 EUR less than the RTX PRO 4500 Blackwell at $3,474 EUR. For budget-constrained teams, the savings may outweigh the spec gap — especially if the smaller card covers your typical workload.
Which should you buy: Radeon PRO W7800 or RTX PRO 4500 Blackwell?
Choose the RTX PRO 4500 Blackwell for maximum capacity — it leads on VRAM, bandwidth, and compute, making it the better fit for large models and training jobs. The Radeon PRO W7800 is the more budget-friendly option ($1,218 EUR less) — a solid choice if your models fit within its 32GB and inference volume is moderate.
