Arc Pro B70 vs Radeon AI PRO R9700: 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 Radeon AI PRO R9700 reaches 645 GB/s against 608 GB/s for the Arc Pro B70, a 6% advantage. Once a model is resident in VRAM, token throughput tracks this figure closely, so the Radeon AI PRO R9700 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 Radeon AI PRO R9700 delivers 48.8 TFLOPS against 22.9 TFLOPS for the Arc Pro B70 — a 113% compute advantage. Training runs and heavy matrix operations will complete proportionally faster on the Radeon AI PRO R9700.
Price & Value
Pricing starts at $1,200 CAD for the Arc Pro B70, a $415 CAD saving over the Radeon AI PRO R9700's $1,615 CAD. 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: Arc Pro B70 or Radeon AI PRO R9700?
Choose the Radeon AI PRO R9700 for maximum capacity — it leads on VRAM, bandwidth, and compute, making it the better fit for large models and training jobs. The Arc Pro B70 is the more budget-friendly option ($415 CAD less) — a solid choice if your models fit within its 32GB and inference volume is moderate.
