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
FP32 throughput is the metric that matters most for training, scientific simulation, and rendering work. The Radeon PRO W5700 posts 8.5 TFLOPS versus 5 TFLOPS on the Radeon PRO W5500, a 70% compute lead. Expect training jobs and heavy matrix math to finish proportionally sooner on the Radeon PRO W5700.
Price & Value
The Radeon PRO W5500 lists from $355 EUR, $116 EUR less than the Radeon PRO W5700 at $471 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?
Go with the Radeon PRO W5700 if you need maximum capacity: it's ahead on VRAM, bandwidth, and compute, so it's the stronger fit for large models and training jobs. The Radeon PRO W5500 is the cheaper pick ($116 EUR less) — worth it if your models already fit within its 8GB and you're not running heavy inference volume.
