Intel’s 11th Gen mobile lineup is expected to launch by mid-2020 with an aim to tackle AMD’s Renoir parts. Like the preceding 10th Gen series, the new product stack will also be formed of two distinct families: Tiger Lake based on the 10nm++ process and Rocket Lake leveraging the 14nm node. This was more or less confirmed in a piece of Linux code which mentions that Rocket Lake can be paired with both Tiger Lake as well as Comet Lake.
All three product stacks, Comet Lake, Rocket Lake and Tiger Lake appear to use the same PCH which means that Intel is planning to launch Rocket Lake for both mobile and desktop platforms by the end of 2020. The desktop lineup, Rocket Lake-S is expected to retain the LGA1200 socket used by the newly announced Comet Lake-S parts, along with the Z490 chipset and added PCIe 4.0 support.
Rocket Lake-U and Y, on the other hand, will be launched alongside Tiger Lake-U. We believe that like Ice Lake, the 10nm++ TGL supply will be limited, so Intel is launching a 14nm family alongside to make up for that. Luckily, despite being another 14nm chip, Rocket Lake is going to feature a new core architecture (Sunny or Willow Cove). As such, we can expect markedly better single-threaded performance thanks to a healthy IPC uplift and core-level enhancements.
While the mobile Rocket Lake parts are expected to launch alongside Tiger Lake in the coming months, the desktop variants should land sometime in late 2020 or early 2021. The latter is supposed to offset the Ryzen 4000 (Vermeer) launch. Therefore, the CPU market will only get more competitive in the coming years.
Update: Tiger Lake-U and Y might launch in October or November 2020. (Source)
