   Apple M5 is a hardware chip, not a documentation site or SaaS product; the probe explicitly shows no llms.txt exists at developer.apple.com (404), and there is no evidence of agent-oriented docs. Since this axis is plausible for a product with developer documentation but no such artifact exists, it is 'none' rather than 'na'.

Mobile endurance

1. power-userThis chip powers thin, quiet, all-day-battery machines — shipping in fanless or low-power designs with credible battery-life evidence

   Apple's M5 ships in fanless iPad Pro and thin, fanless-adjacent MacBook Pro designs with documented all-day battery claims (up to 24 hours video streaming) and community benchmarks confirming real-world performance/efficiency gains over M4. Community discussion corroborates strong CPU efficiency and performance-per-watt improvements, consistent with Apple's power-efficiency-first chip design philosophy. missing for 10: independent third-party battery-life testing (e.g., reviewer runtime benchmarks) and explicit fanless-design confirmation for the specific M5 MacBook Pro SKU.

   Apple M4 Pro—none0/10

   The evidence only offers a generic 'legendary power efficiency' marketing line (apple-m4-pro-docs-3) with no battery-life benchmarks, no mention of fanless designs, and no quiet-operation claims specific to M4 Pro (which typically ships in fan-equipped MacBook Pro/Mac mini/Studio models). Community comments even push back on Apple's efficiency comparison methodology (apple-m4-pro-comm-6), and no independent battery-life data is cited. Missing for 10: fanless/low-power device pairing evidence, credible battery-life benchmarks, independent corroboration of efficiency claims.

Perf per watt

   Apple M5—none0/10

   No documented power envelope (TDP/wattage) or independent sustained-load/thermal-throttling testing is present; evidence covers battery-video-hours, peak GPU/CPU speedup claims, and short benchmark scores, none of which address sustained render/export performance-per-watt over time.

   Apple M4 Pro~partialcommunity4/10

   Apple's marketing repeatedly claims 'legendary power efficiency' and faster rendering/exports (ray tracing, ML acceleration), but there's no documented sustained power envelope (TDP under load) or independent thermal/throttling benchmarks in the pack. Community comments even push back on efficiency comparison claims as 'grasping for a headline' and question benchmark methodology, though this doesn't rise to a concrete contradiction of sustained-render throttling. missing for 10: independent long-render/export sustained benchmark data, documented thermal/power envelope specs, third-party throttling tests.

Spec disclosure

1. power-userComparison-shop from a real spec sheet — the vendor publishes clocks, power, memory support, and AI TOPS with test conditions, instead of marketing adjectives

   weight 2 · round drawn
   Apple M5—none0/10

   Apple's own M5 materials list core counts and unified memory bandwidth (153GB/s) but omit clock speeds, TDP/power figures, and AI TOPS numbers with test conditions — instead using relative marketing comparisons like 'up to 4x GPU compute' or '30% higher graphics performance' (apple-m5-comm-8). The runtime probe explicitly confirms Apple publishes no clock-speed, TDP, or ARK-style spec sheet, with the newsroom post serving as the only 'spec disclosure' (apple-m5-probe-rt-1).

   The evidence pack contains only marketing language ('stunning performance', 'blazing speed', 'legendary power efficiency') with no published clock speeds, power/wattage figures, memory bandwidth specs, or AI TOPS numbers with defined test conditions. Community comments explicitly call out the lack of transparent, apples-to-apples benchmarking ('Why aren't they benching it against the M3?', 'grasping for a headline... why not compare apples to apples'), reinforcing that no real spec sheet is provided.
