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 W5700 lists from $627 AUD, $218 AUD less than the Radeon PRO W5500 at $846 AUD. 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?
The two cards are well matched for similar workloads, so let the spec you care about most decide: VRAM for model capacity, memory bandwidth for inference speed, or FP32 compute for training throughput.
