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 $190 USD, $67 USD less than the Radeon PRO W5700 at $257 USD. 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 ($67 USD less) — a solid choice if your models fit within its 8GB and inference volume is moderate.

Frequently Asked Questions

Can the Radeon PRO W5500 or Radeon PRO W5700 run large language models?

Yes — with 8GB 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 W5500 or the Radeon PRO W5700?

The Radeon PRO W5700 is faster for token generation — its 448 GB/s memory bandwidth vs 224 GB/s on the Radeon PRO W5500 is the primary driver of inference throughput in autoregressive models.

Which is better for AI training?

The Radeon PRO W5700 has the advantage at 8.5 TFLOPS vs 5 TFLOPS, making training runs proportionally faster than on the Radeon PRO W5500.
