Arc Pro B50 vs Arc Pro B70: In-Depth Breakdown
VRAM: Arc Pro B50 vs Arc Pro B70
The Arc Pro B70 carries 32GB of VRAM versus 16GB on the Arc Pro B50. VRAM capacity is the primary constraint for running AI models without quantization — a 70B-parameter model in FP16 requires roughly 140GB, and even smaller models benefit from extra headroom. The 16GB advantage here means the Arc Pro B70 can run larger models natively and handle bigger batch sizes in production.
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 Arc Pro B70 delivers 608 GB/s versus 224 GB/s on the Arc Pro B50, a 171% edge. For models already loaded into VRAM, token generation speed scales closely with this number: the Arc Pro B70 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 Arc Pro B70 delivers 22.9 TFLOPS against 10.65 TFLOPS for the Arc Pro B50 — a 115% compute advantage. Training runs and heavy matrix operations will complete proportionally faster on the Arc Pro B70.
Price & Value
The Arc Pro B50 lists from $428 USD, $572 USD less than the Arc Pro B70 at $1,000 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: Arc Pro B50 or Arc Pro B70?
Choose the Arc Pro B70 for maximum capacity — it leads on VRAM, bandwidth, and compute, making it the better fit for large models and training jobs. The Arc Pro B50 is the more budget-friendly option ($572 USD less) — a solid choice if your models fit within its 16GB and inference volume is moderate.
