   The axis applies to this product kind (peer products hold positive or none verdicts on this story), so lack of evidence for an applicable capability is "none", never "na". (na/none harmonized at arena bring-up — see pipeline/scripts/na-harmonize.ts.)

   AMD Ryzen AI Max+ 395—none0/10

   The evidence pack contains no mention of a socket, upgrade path, or multi-generation platform commitment for the Ryzen AI Max+ 395; all specs shown are TDP, display, storage, and OS support with no socket/upgrade language. Community citations also reference it in fixed-configuration devices (e.g., Framework Desktop, mini-PCs) rather than a socketed upgrade path. missing for 10: any documented socket name, generational upgrade commitment, or evidence of user-replaceable CPU in a motherboard.

Mobile endurance

   weight 2 · round drawn
   Apple M4 Max—none0/10

   M4 Max targets high-end MacBook Pro/Mac Studio designs, not fanless or ultra-low-power machines, and the only battery-life claim (apple-m4-max-docs-6) is vague marketing language with no concrete battery-life benchmarks; community commentary (apple-m4-max-comm-7) explicitly notes the absence of any real battery-run-time data. Missing for 10: evidence of a fanless/thin M4 Max design, independent battery-life benchmarks or hours-of-use figures.

   AMD Ryzen AI Max+ 395—none0/10

   The evidence pack shows a configurable TDP range of 45–120W and OS/platform specs, but contains no mention of fanless designs, thin-and-light chassis, or battery-life benchmarks; a community comment even complains AMD hasn't focused on reducing power usage. This is a fair axis for a laptop-class chip, but no supporting evidence exists.

   Apple M4 Max~partialcommunity3/10

   Apple's docs assert energy efficiency and exceptional battery life alongside pro-workload performance (e.g., real-time RAW de-noising), but there are no documented power envelope figures (watts, sustained clocks) nor independent third-party testing of sustained performance-per-watt during long renders/exports. Community threads focus on raw Geekbench comparisons and skepticism about benchmark validity, not throttling behavior. Missing for 10: explicit power envelope specs, independent sustained-load/thermal throttling benchmarks, and real-world creator render tests confirming no throttling.

   AMD documents a configurable TDP range (45-120W) for the chip, but there is no independent benchmark or hands-on testing demonstrating sustained performance-per-watt or absence of thermal throttling during long renders/exports; community comments focus on LLM token throughput and even note frustration that AMD hasn't addressed power usage. missing for 10: independent sustained-load/thermal throttling benchmarks, creator-workload (render/export) power efficiency data, cooling/chassis-specific real-world tests.

   All evidence items are marketing-style claims ('rips through workloads', 'blazing speed', 'ultimate choice for video professionals') with no clock speeds, power/wattage figures, memory bandwidth numbers, or AI TOPS values with stated test conditions — the exact opposite of what the story requests. Community items are benchmark discussions, not vendor spec disclosures, and a llms.txt probe returned 404.

   AMD's product page does publish concrete spec-sheet items (cTDP 45-120W, NVMe RAID support, OS support, display counts, voltage offset support) rather than pure marketing prose, and the Ryzen AI docs give technical detail on the software stack. However, the pack contains no explicit clock-speed figures or AI TOPS number with stated test conditions, and community commentary explicitly complains that AMD's benchmark comparisons are misleading/incomplete rather than rigorously documented. missing for 10: published boost/base clock figures, an explicit AI TOPS figure with test-methodology footnotes, and independent verification that the spec sheet's numbers hold up under real-world testing.
