New and important details about Intel’s next-generation Panther Lake-H series processors have leaked. These processors will feature a 16-core hybrid design, advanced integrated graphics, and a combination of different manufacturing processes.

Intel Panther Lake-H Leaked

According to the leaked information, Panther Lake-H processors will feature a hybrid design consisting of three different components. The processor’s main components, the CPU and SoC dies, are manufactured using Intel’s own 18A process.

In contrast, TSMC’s N3E process is preferred for the integrated GPU die. Additionally, the Platform Controller Die (PCD) part features TSMC N6 technology. With this unified structure, Panther Lake-H offers NPU support for AI workloads exceeding 50 TOPS, an LPDDR5X memory controller, and expanded media-connectivity solutions.

One of the most notable innovations in the processor is the upgraded Xe3 “Celestial” GPU cores. This integrated graphics unit delivers 15 to 30 percent higher integrated gaming performance compared to the previous-generation Lunar Lake. This GPU, featuring 12 execution units, claims to outperform AMD’s Strix Point APU solutions, especially under a 45W TDP. Leaks support this expectation.

Clock speeds aren’t significantly increased. However, thanks to the core balance and the active use of efficient LPE cores in applications, Panther Lake is said to be able to match Arrow Lake’s multi-threaded performance.

Single-core performance is expected to be similar to Lunar Lake. Intel had planned to release these processors in the second half of 2025, with volume production starting as early as the first quarter of 2026.

However, sources report continued low yields for the 18A line. This raises uncertainty about the series’ widespread production and its availability by the end of 2025. Despite this, Intel’s competitiveness against AMD in the laptop market is expected to increase thanks to increased GPU power and efficiency gains.
