In the Bilibili forums, a user (via harukaze5719) has posted a thread that exposes the supposed specs of three Intel 11th Generation Rocket Lake-S processors. The chips are engineering samples that the user appears to have picked up on the black market, so it is possible that actual specs would vary from those shown.
The Core i9-11900, which comes packed with an eight-core, 16-thread configuration and a 16MB L3 cache, corresponds to the first processor. The base clock is set at 1.8 GHz, while at 4.5 GHz, the single boost clock peaks. The all-core boost seems to max out at 4 GHz on the Core i9-11900. It is a 65W processor, but it is just PL1 (power level 1) rating. Currently, the PL2 value is set at 224W.
The same core specifications of Core i9-11900 are shared by Core i7-11700K and Core i7-11700 both. The chip reportedly flaunts a 3.4 GHz base clock and a 4.8 GHz single base clock in the case of the Core i7-11700K. At 4.3 GHz, the all-core boost clock is a bit lower. The Core i7-11700K has a 125W PL1 and a 250W PL2 rating, which is no surprise.
Finally, with a 1.8 GHz base clock, the Core i7-11700 allegedly checks in but has a single boost clock that hits 4.4 GHz. However, the all-core boost clock is stuck at 3.8 GHz. The Core i7-11700 also adheres to the 65W PL1 and 224W PL2 constraints, as the Core i9-11900.
According to Bilibili user, the default XMP frequency for Rocket Lake-S is DDR4-3200. However, on an unspecified B560 motherboard, it was possible to combine the processors with DDR4-4133 memory. This is an interesting discovery as it appears that on the B560 chipset, Intel might have allowed memory overclocking.
If real, this will be a groundbreaking shift in the right direction since the chipmaker’s lesser chipsets are historically limited to the officially supported memory frequency for that particular generation of processors. For instance, current motherboards B460, H470, and H410 are limited to DDR4-2933 memory modules, which are the official requirements of the Comet Lake-S processors. It is a known fact that Rocket Lake-S will wield Cypress Cove cores, which will give double-digit instruction per cycle (IPC) improvements, according to Intel.
