Quadro RTX 4000 vs Radeon PRO W5500: In-Depth Breakdown
Inference Speed: Memory Bandwidth
The rate data moves to the compute units — memory bandwidth — is what caps autoregressive inference speed (token generation in LLMs). Here the Quadro RTX 4000 reaches 416 GB/s against 224 GB/s for the Radeon PRO W5500, a 86% advantage. Once a model is resident in VRAM, token throughput tracks this figure closely, so the Quadro RTX 4000 generates tokens proportionally faster on 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
Pricing starts at $434 AUD for the Quadro RTX 4000, a $412 AUD saving over the Radeon PRO W5500's $846 AUD. Teams working within a tighter budget may find that saving worth more than the spec gap, particularly if the smaller card already covers their typical workload.
Which should you buy: Quadro RTX 4000 or Radeon PRO W5500?
Both cards serve similar workloads. Base your decision on whichever spec matters most: VRAM for model capacity, memory bandwidth for inference speed, and FP32 compute for training throughput.
