Leaked Panther Lake CPU doesn't feature any hyperthreading and features 12 cores, which likely brings the hybrid core configuration with Performance, Efficient, and Low Power Efficient Cores.
Panther Lake Mobile Chip Specs Leaked In Intel GFX CI Portal: 12 Cores, Rumored Through a 4P+4E+4LPE Configuration and 3000 MHz of Base Clock
Intel's upcoming Panther Lake mobile chips are now surfacing online through various leaks, revealing what could be the possible specifications for some of the SKUs. Panther Lake is essentially divided into PTL-H and PTL-U, with former being aimed at mainstream budget to mid-range mobile segment while the latter will focus on delivering higher power efficiency and more battery life in mobile devices.
We recently reported on the supposed specifications of some of these chips, bringing as many as 16 cores in total, which appears to be inline with the latest leak by @InstLatX64. The CPU family was spotted in Intel GFX CI (Graphics Continuous Integration) Portal, that is focused on automated testing of Intel's open-source Linux graphics drivers. Intel Panther Lake is explicitly mentioned in the portal, revealing crucial information about the family, confirming previous reports.
Panther Lake will be the last to share the Family 6, after which, Intel will transition to Family 18 with Nova Lake. The model "0xCC" is Panther Lake's model ID and the Stepping "0x2" indicates the silicon revision. This Panther Lake chip in the portal features 12 cores, which could be a combination of 4 Performance Cougar Cove cores and 8 Efficient Darkmont Cores. However, it could also be possible that it uses a 4P+4E+4LPE (Low Power Efficient) configuration. No solid report confirms either of the configuration, so, we will have to wait for more reliable reports.
The CPU won't feature any hyperthreading and another crucial specification revealed is its base clock of 3.0 GHz. According to another leak, the CPU reportedly boasts 3.2 GHz of boost speed but remember that these may not be the final specifications. Previously, we saw Core Ultra 7 255H mentioned in the portal with 3.7 GHz base clock, which didn't come out to be true, but on the other hand the Core Ultra 5 238V was mentioned with the correct base clock of 2.1 GHz before the launch. Therefore, take these specs with a grain of salt.
Intel Panther Lake will be based on Intel 18A node and is expected to launch in the fourth quarter this year. However, there are issues with the production of these chips since Intel is reportedly struggling with the 18A yield rates.
