Intel Panther Lake Leak Reveals 45W TDP for High-End Variant

Key Takeaways

1. Intel’s Panther Lake-H chip will feature a combination of 4 performance cores, 8 efficiency cores, and 4 LPE cores.
2. The CPU will use Intel’s 18A technology and the GPU will be made with TSMC’s N3E process, while the Platform Control Die will be on TSMC’s N6.
3. The integrated GPU is expected to offer up to 12 EU based on Intel’s Celestial architecture.
4. The LPE cores will be fully functional for applications, marking an improvement over previous generations.
5. The premier Panther Lake SKU may have a maximum TDP of 45 Watts, higher than the Core Ultra 9 288V’s 30 Watts.

YouTuber Moore’s Law is Dead has shared intriguing insights about Intel’s upcoming Panther Lake platform for laptops. According to the latest information, Intel’s high-end Panther Lake-H chip is expected to feature 4 Cougar Cove performance cores, 8 Darkmony efficiency cores, and 4 Darkmont LPE cores.

Specifications Breakdown

The CPU tile will utilize Intel’s 18A technology, while the GPU die will be produced using TSMC’s N3E process, and the Platform Control Die will be crafted on TSMC’s N6. On the graphics front, Panther Lake is anticipated to launch with an integrated GPU offering up to 12 EU, built on Intel’s Celestial architecture.

Conflicting Information

This news contradicts a leak from the previous year, which forecasted a lineup of five Panther Lake CPUs, with the top model expected to include 6 P-cores, 8 E-cores, and 4 LPE cores. However, that same leak indicated that the two SKUs featuring 6 P-cores were lagging behind in development compared to the model with 4 P-cores.

Enhanced Usability

Moreover, the latest leak suggests that the LPE cores in Panther Lake will be fully functional for applications this time around, a feature that was not available in earlier generations. Moore’s Law is Dead estimates a potential IPC increase of 5-13%, but notes that predicting IPC improvements in Intel’s recent CPUs has proven to be difficult.

The premier Panther Lake SKU is said to have a maximum Thermal Design Power (TDP) of up to 45 Watts, which is a bit higher than the Core Ultra 9 288V’s 30 Watts. Furthermore, there may be a possibility of pushing other (non-Core Ultra 9) SKUs to that TDP, unlike what was achievable with Lunar Lake.
