Panther Lake (microprocessor)

Panther Lake was a codename for a planned line of Intel microprocessors. It was intended to be the successor to the Broadwell microarchitecture, scheduled for release sometime after 2014 or 2015. Panther Lake was expected to utilize a new microarchitecture and fabrication process, potentially a shrink of Broadwell's 14nm process or a transition to a smaller node.

Little specific information about Panther Lake was ever publicly released by Intel. The codename disappeared from public roadmaps after the delays and eventual release of Broadwell and the subsequent introduction of Skylake. Intel's tick-tock model, which involved alternating between new microarchitectures (tick) and process shrinks (tock), had already begun to falter around this time.

The cancellation of Panther Lake is believed to be related to the difficulties Intel experienced in transitioning to smaller manufacturing processes. The development and yield challenges associated with 10nm and 7nm processes led to significant delays and changes in Intel's product roadmap.

As a result, Panther Lake never materialized as a commercial product. The functionalities and performance improvements that might have been included in Panther Lake were likely incorporated into subsequent Intel architectures like Skylake, Kaby Lake, Coffee Lake, and later generations.
