Intel Panther Leak reveals complete CPU list, boost clocks and max TDP

At its recent Panther Lake presentation, Intel only revealed architectural details about its upcoming laptop chips. Crucial information, such as its SKU names, CPU/GPU core counts, and clock speeds, is still a mystery. While numerous leaks have revealed parts of that information, they have been contradictory, especially regarding some Core Ultra X-branded SKUs. Even the iGPUs get a new Arc B390 moniker, as confirmed by a Geekbench listing. X leaker Jaykihn has now posted the base/boost clocks of each Panther Lake CPU. 

• Core Ultra X9 388H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 5.1 GHz CPU boost, 12 EU Xe3 iGPU
• Core Ultra X9 386H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 4.9 GHz CPU boost, 12 EU Xe3 iGPU
• Core Ultra X7 368H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 5.0 GHz CPU boost, 12 EU Xe3 iGPU
• Core Ultra X7 366H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 4.8 GHz CPU boost, 12 EU Xe3 iGPU
• Core Ultra X7 358H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 4.8 GHz CPU boost, 12 EU Xe3 iGPU
• Core Ultra X7 356H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 4.7 GHz CPU boost, 12 EU Xe3 iGPU
• Core Ultra 5 338H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 4.7 GHz CPU boost, 10 EU Xe3 iGPU
• Core Ultra 5 336H: 4P + 8E+ 4 LP-E, 65-80 Watt boost TDP, 4.6 GHz CPU boost, 4 EU Xe3 iGPU
• Core Ultra 7 365: 4P + 0E+ 4 LP-E, 55 Watt boost TDP, 4.8 GHz CPU boost, 4 EU Xe3 iGPU
• Core Ultra 7 355: 4P + 0E+ 4 LP-E, 55 Watt boost TDP, 4.7 GHz CPU boost, 4 EU Xe3 iGPU
• Core Ultra 5 335: 4P + 0E+ 4 LP-E, 55 Watt boost TDP, 4.6 GHz CPU boost, 4 EU Xe3 iGPU
• Core Ultra 5 325: 4P + 0E+ 4 LP-E, 55 Watt boost TDP, 4.5 GHz CPU boost, 4 EU Xe3 iGPU
• Core Ultra 5 332: 2P + 0E+ 4 LP-E, 55 Watt boost TDP, 4.4 GHz CPU boost, 2 EU Xe3 iGPU
• Core Ultra 5 322: 2P + 0E+ 4 LP-E, 55 Watt boost TDP, 4.3 GHz CPU boost, 2 EU Xe3 iGPU

The above list adds a bunch of CPUs not seen previously, such as the Core Ultra 3x6 lineup. Plus, it doesn't include the previously rumoured U lineup and shows just H and non-H models. Instead, we see two SKUs with the 2+0+2 layout bundled into the Core Ultra 5 lineup. It further muddies the waters with an even more confusing naming schemes. While Jaykihn has a stellar track record when it comes to Intel leaks, we won't know if the above information is accurate until CES 2026, which is when Intel plans to show off Panther Lake in its entirety.
