A previous leak revealed Intel would introduce four new Core Ultra X-branded chips with its Panther Lake lineup alongside the regular Core Ultra models. At the time, it was unknown how they would differ from other Panther Lake CPUs. New leaks from Chiphell and Weibo sheds more light on that matter and shows us the entire Panther Lake lineup in all its glory. 

• Core Ultra X 3_8H lineup
• Core Ultra X9 388H (4P, 8E, 4LPE, 12 EU Xe3 iGPU), rumoured 45W TDP 
• Core Ultra X7 368H (4P, 8E, 4LPE, 12 EU Xe3 iGPU)
• Core Ultra X7 358H (4P, 8E, 4LPE, 12 EU Xe3 iGPU)
• Core Ultra X5 328H (4P, 4E, 4LPE, 10 EU Xe3 iGPU)

The previously rumoured Core Ultra X lineup will differentiate themselves from other models with a more powerful iGPU. In Lunar Lake, the last digit (6/8) denoted how much on-package RAM each CPU featured. With Panther Lake, it will be used to denote its iGPU prowess. There has been some conflicting information about where Intel will put the ‘X’, with some leakers stating the CPUs could be called Core Ultra 9 X388H and so on. The next line of CPUs confirm there will be no Core Ultra 3_6 models this time. 

• Core Ultra 3_5H lineup
• Core Ultra 9 385H (4P, 8E, 4LPE, 4 EU Xe3 iGPU)
• Core Ultra 7 355H (4P, 8E, 4LPE, 4 EU Xe3 iGPU)
• Core Ultra 7 345H (4P, 8E, 4LPE, 4 EU Xe3 iGPU)
• Core Ultra 5 325H (4P, 4E, 4LPE, 4 EU Xe3 iGPU)

Lastly, Panther Lake also includes some U-branded parts. If their last-gen counterparts are anything to go by, they’ll likely cap out at 15 Watts and power ultra-portable thin-and-light laptops. Specs-wise, they lose the E-cores and keep everything else. The Core Ultra 3 model will cut down the P-core count further to two. 

• Core Ultra 3_0U lineup
• Core Ultra 7 360U (4P, 0E, 4LPE, 4 EU Xe3 iGPU)
• Core Ultra 5 350U (4P, 0E, 4LPE, 4 EU Xe3 iGPU)
• Core Ultra 5 340U (4P, 0E, 4LPE, 4 EU Xe3 iGPU)
• Core Ultra 3 320U (2P, 0E, 4LPE, 4 EU Xe3 iGPU)

As always, the above information is a rumour and be treated as such until Intel officially shows off Panther Lake in a couple of days. It is unclear if Intel will reveal all twelve CPUs together, but if Lunar Lake is anything to go by, that is within the realm of possibilities.
