Rumor mill: Intel Panther Lake laptop CPUs are scheduled to launch later this year, but the company has yet to outline technical specs for any product in the upcoming lineup. A new rumor suggests that all Panther Lake processors have been delayed until next year – except for one model featuring a configuration not seen in prior leaks.
According to this new information, Intel would introduce Panther Lake with the Core Ultra 300 laptop CPUs and just a single model would arrive in the fourth quarter of 2025. Meanwhile, another recent leak has revealed alleged high-resolution renders of the new architecture.
The debut Panther Lake chip would feature 4 performance cores, 8 efficiency cores, no low-power efficiency cores, and 4 Xe3 Celestial GPU cores. Drawing 45W of power, the CPU may be paired with discrete graphics for use in gaming notebooks and high-end performance laptop models.
intel 18A Panther Lake first High Level SKU : 4 P-Cores + 8 E-Cores + 0 LP-E Cores + 4 Xe3 Cores (45W) will launch in Q4 2025 , other SKU will launch in Q1 2026 .

Interestingly, this configuration was not mentioned in earlier reports. Late last year, prominent leaker Jaykihn outlined five CPUs under Intel’s high-performance “H” designation, all of which included low-power efficiency cores.
If the latest reports are accurate, Intel would launch these other processors in the Q1 2026. The most powerful Panther Lake CPU is expected to draw 45W and include 6 Cougar Cove performance cores, 8 Skymount efficiency cores, 4 low-power efficiency cores, and 4 GPU cores.
Panther Lake, which will succeed last year’s Lunar Lake lineup, is a critical release for Intel as it marks the debut of the company’s 18A semiconductor node. This node is designed to improve performance per watt by 15 percent and increase chip density by 30 percent. Intel announced that it began refining the 18A manufacturing process through risk production in early April. However, the delay of most Panther Lake configurations suggests a revision to the company’s schedule.

The new node incorporates gate-all-around (GAA) transistors and backside power delivery – key innovations in both Intel’s and TSMC’s next-generation semiconductors.
A delay from Intel would narrow the gap between the debut of 18A and TSMC’s N2 node, scheduled for next year and also employing GAA technology. N2 is expected to premiere in the iPhone 18 Pro’s SoC, followed by Intel’s Nova Lake chips and unnamed AMD chips.
Intel also aims to use 18A for its Clearwater Forest server CPUs next year. Further performance-per-watt improvements are slated for 2026 with the 18A-P process. The company also intends to start production on the 14A node in 2027 and 18A-PT in 2028.
