GDDR7 vs HBM3E for Inference: Bandwidth per Dollar Stops Being the Question
The first instinct when pricing an inference accelerator is to compare bandwidth numbers. HBM3E gives you around 1.2 TB/s per stack and up to eight stacks, so 8 to 9.6 TB/s on a top-end part. GDDR7 on a 384-bit bus gives you roughly 1.5 TB/s. The HBM part looks six times better, costs roughly three…
