Memory Bandwidth per TDP Watt

Formula: memory bandwidth (GB/s) ÷ rated board power TDP (W) × 100.
Price class: launch MSRP (USD, each row links its source). Launch MSRP is historical — it is not a current street price, and we publish no used-market prices because none are verified. See methodology.

GPUs ranked by memory bandwidth per watt of rated TDP — a spec-level efficiency proxy for always-on home-AI servers and SFF builds, not measured workload throughput per watt. Computed live from our database — every row's launch price links to its source.

Method: this is a spec-level ranking, not a measured performance ranking — scores divide one database spec by launch MSRP (or rated TDP). Only GPUs with a source-linked launch price appear; 20 GPUs are excluded for lacking sourced pricing. These are launch MSRPs, not current street prices; no used-market prices are tracked, so none are shown. Unified-memory systems list GPU-addressable unified memory, not discrete VRAM. See methodology.

What to do with these rankings

High VRAM capacity per dollar means more model capacity for the money — start there when deciding which models fit your budget. High memory bandwidth per dollar tracks the spec that most limits token generation speed. High memory bandwidth per TDP watt suits always-on servers and small-form-factor builds.

Then compare finalists head-to-head in the GPU comparison tool, check which models fit each card, or browse all sourced benchmark results.
