   AMD Ryzen 9 9950X3D✓fullclaimed8/10

   AMD explicitly documents a multi-year socket support commitment ('AMD is the only processor manufacturer committed to multi-year socket support... start with what fits your build today and upgrade to next-gen performance tomorrow'), directly matching the platform-upgrade story. Missing for 10: independent/community confirmation of actual multi-generation compatibility (e.g. AM5 supporting multiple CPU generations in practice) and specifics on how many generations/years are guaranteed.

   Intel Core Ultra 9 285K—none0/10

   The evidence pack contains no mention of the CPU's socket (LGA1851) or any stated multi-generation upgrade commitment; specs pages cover cache/clocks/vPro/ECC but not platform longevity. This axis clearly applies to a desktop CPU purchase decision, but no documentation here confirms or denies a multi-gen socket promise.

   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.)

Perf per watt

   AMD Ryzen 9 9950X3D~partialcommunity5/10

   AMD's marketing highlights creator workloads (DaVinci Resolve, 3D rendering) and tunable power via PBO, and independent reviews broadly call the chip 'energy efficient' with 'strong productivity performance,' but none of the evidence gives documented power envelope specs or dedicated long-render/export sustained perf-per-watt testing. missing for 10: explicit TDP/power envelope documentation, independent sustained-load (render/export) thermal-throttle or perf-per-watt benchmarks.

   Intel Core Ultra 9 285K~partialcommunity5/10

   Independent reviews (Tom's Hardware) confirm the 285K delivers strong productivity/rendering gains with improved power consumption and efficiency versus its 14900K predecessor, and Intel's spec pages document power envelopes (base/turbo power). However, the same reviews note it trails AMD's 9950X in raw perf-per-watt, and no evidence specifically tests sustained long-render/export thermal throttling behavior. Missing for 10: dedicated sustained-load/throttling benchmarks over long export durations, explicit perf-per-watt superiority claims corroborated independently, and creator-specific workload power testing.

   The evidence pack is dominated by marketing language ('personalize performance', 'colossal 208MB', 'accelerate every step') rather than a transparent spec sheet; while a few technical bullets exist (ECC support, NVMe RAID modes, supported OSes), there is no evidence of published clock speeds, TDP/power figures, memory speed/type support, or AI TOPS numbers with stated test conditions.

   Intel's ARK specifications page (and the runtime probe) confirms a machine-fetchable spec sheet listing clocks, cache, ECC support, vPro eligibility, and supported AI frameworks (OpenVINO, DirectML, ONNX RT), giving power-users concrete comparable data beyond marketing language. However, the evidence pack lacks explicit AI TOPS figures with stated test conditions, detailed base/turbo power figures, or memory speed/latency specs with test methodology, and much of the docs pack is marketing copy rather than spec data. missing for 10: explicit AI TOPS numbers with test conditions, full power/TDP breakdown, independent verification of spec accuracy.
