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.

Frequently Asked Questions

Can the Radeon PRO W7800 or RTX PRO 4500 Blackwell run large language models?

Yes — with 32GB of VRAM each, both support a similar range of models. Memory bandwidth and compute throughput then differentiate their performance.

Which is faster for LLM inference, the Radeon PRO W7800 or the RTX PRO 4500 Blackwell?

The RTX PRO 4500 Blackwell is faster for token generation — its 896 GB/s memory bandwidth vs 576 GB/s on the Radeon PRO W7800 is the primary driver of inference throughput in autoregressive models.

Which is better for AI training?

The RTX PRO 4500 Blackwell has the advantage at 53.8 TFLOPS vs 45.2 TFLOPS, making training runs proportionally faster than on the Radeon PRO W7800.
