Quadro RTX 4000 vs Radeon PRO W5500: 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 Quadro RTX 4000 delivers 416 GB/s versus 224 GB/s on the Radeon PRO W5500, a 86% edge. For models already loaded into VRAM, token generation speed scales closely with this number: the Quadro RTX 4000 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 Quadro RTX 4000 delivers 7.1 TFLOPS against 5 TFLOPS for the Radeon PRO W5500 — a 42% compute advantage. Training runs and heavy matrix operations will complete proportionally faster on the Quadro RTX 4000.
Price & Value
The Radeon PRO W5500 lists from $5,208 SEK, $702 SEK less than the Quadro RTX 4000 at $5,910 SEK. For budget-constrained teams, the savings may outweigh the spec gap — especially if the smaller card covers your typical workload.
Which should you buy: Quadro RTX 4000 or Radeon PRO W5500?
Choose the Quadro RTX 4000 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 ($702 SEK less) — a solid choice if your models fit within its 8GB and inference volume is moderate.
