Radeon PRO W5500 vs Radeon PRO W5700: 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 Radeon PRO W5700 delivers 448 GB/s versus 224 GB/s on the Radeon PRO W5500, a 100% edge. For models already loaded into VRAM, token generation speed scales closely with this number: the Radeon PRO W5700 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 Radeon PRO W5700 delivers 8.5 TFLOPS against 5 TFLOPS for the Radeon PRO W5500 — a 70% compute advantage. Training runs and heavy matrix operations will complete proportionally faster on the Radeon PRO W5700.
Price & Value
The Radeon PRO W5500 lists from $229 EUR, $250 EUR less than the Radeon PRO W5700 at $479 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 W5500 or Radeon PRO W5700?
Choose the Radeon PRO W5700 for maximum capacity — it leads on VRAM, bandwidth, and compute, making it the better fit for large models and training jobs. The Radeon PRO W5500 is the more budget-friendly option ($250 EUR less) — a solid choice if your models fit within its 8GB and inference volume is moderate.
