As for what models are on tap, the latest leak highlights three engineering samples, two of which are purportedly second-revision models, or ES2 chips. The other one, a Core i7-11700, is said to be a first revision engineering sample, or ES1 part.
Leaked 11th Gen Intel Rocket Lake-S Second-Revision Engineering Sample (ES2) CPUs
Moving on to the more interesting leaks, the first of the ES2 chips is the Core i7-11700K. The specifications on this part will be more closely aligned with the final silicon, and might even match the datasheet exactly. Time will tell. In the meantime, we have some leaked specifications to digest.
Like the non-K variant, this is an 8-core/16-thread processor, but with an unlocked multiplier. It reportedly has a 3.4GHz base clock, 4.3GHz all-core Turbo clock, and a 4.8GHz single-core Turbo clock. The revised ES chip also supports PCIe 4.0 and XMP profiles of 3,200MHz or higher, and sports working Xe graphics. For this ES2 part, the PL1 is set at 125W and the PL2 at 250W.
The other leaked ES2 Rocket Lake-S processor is the Core i9-11900. This is another 8-core/16-thread part, with a 1.8GHz base clock, 4GHz all-core Turbo clock, and 4.5GHz single-core Turbo clock. Those clocks are said to be the same as the ES1 variant, but the ES2 chip fixes some of the bugs with the initial engineering sample.
Again, I would anticipate a higher base clock in the finalized silicon, but we’ll have to wait and see. As currently configured (in the ES2 part), it has a PL1 of 65W and a PL2 of 224W, and like the other ES2 chip, it supports PCIe 4.0 with a default XMP profile of 3,200MHz. The onboard Xe graphics work as well. Lacking a “K” designation, the multiplier is locked on this one.
What this all essentially means is that Intel is on track to launch Rocket Lake-S in the first quarter of next year. Furthermore, it is expected that Intel will announce some of its next-gen CPUs during the Consumer Electronics Show in January 2021.
