Intel's upcoming Core Ultra X9 388H is up to 8.7% faster for 1T perf than Ryzen AI Max+ 395 — Panther Lake gains significant ground on Strix Halo in early Geekbench leak

A Geekbench leak for Intel’s unreleased Panther Lake flagship, the Core Ultra X9 388H, shows 3,057 single‑core and 17,687 multi‑core scores—outpacing Intel’s prior Arrow Lake mobile chips and delivering a single‑thread lead of about 8.7% over AMD’s Ryzen AI Max+ 395 while matching its multi‑thread output; the chip reportedly boosts to 5.1GHz, uses a 16‑core 4P+8E+4 LP‑E layout with 12 Xe3 iGPU cores and has a 45W default TDP versus Ryzen’s 55W, suggesting potential efficiency advantages. These early results suggest Panther Lake could materially close the performance gap with AMD in high‑end mobile SKUs, but they are from a single benchmark run and broader validation is needed, and rising memory prices could limit Panther Lake’s market impact by driving laptop price inflation.

Analysis

A leaked Geekbench entry for Intel's unreleased Core Ultra X9 388H shows 3,057 single‑core and 17,687 multi‑core scores and a reported 5.1 GHz boost, putting the SKU roughly 8.7% ahead of AMD's Ryzen AI Max+ 395 on single‑thread and essentially level on multi‑thread performance. The X9 388H is a 16‑core part in a 4P+8E+4 LP‑E configuration with 12 Xe3 iGPU cores and a 45W default TDP versus the Ryzen AI Max+ 395's 55W, implying a potential performance‑per‑watt and integrated graphics advantage in mobile designs. These results beat Intel's prior Arrow Lake mobile SKUs and are comparable to the higher‑core 275HX in MT composites, but the data come from a single Geekbench leak so statistical variance and system configuration differences could materially change rankings once more runs appear. Separately, the article flags a macro headwind: surging memory prices may force OEM markups on Panther Lake laptops, which could limit unit demand or mute the commercial upside even if on‑chip performance is strong.

Key Decisions for Investors

• Consider a measured, time‑limited increase in exposure to Intel (INTC) on a product‑cycle rebound thesis, but size positions conservatively until multiple independent benchmarks and shipping SKUs validate the leaked performance
• Defer adding to AMD (AMD) positions until AMD publishes rebuttal benchmarks or updates product pricing/roadmap, and consider short‑term hedges if you hold concentrated AMD exposure given the potential for Panther Lake to reclaim mobile performance leadership
• Monitor memory pricing and OEM laptop ASP guidance closely—if memory‑driven price inflation materializes, reduce cyclically exposed hardware bets or shift to suppliers/OEMs with better pricing power
• Use clear verification triggers (multiple benchmark averages, independent MT and iGPU tests, and initial OEM designs/thermals) before increasing allocation; reassess within one to two quarters as Panther Lake samples and commercial devices emerge
