i9-11900, i7-11700, i7-11700K specs reportedly revealed in new leak

A Bilibili user (via harukaze5719) has posted a thread on the Bilibili forums revealing the purported specs of three Intel 11th generation Rocket Lake-S processors. The chips are engineering samples that the user claims to have picked up on the black market, so the final specs will likely be different from those shown.

The first processor corresponds to the Core i9-11900, which comes with an 8-core, 16-thread configuration and 16MB L3 cache. The base clock is set at 1.8GHz, while the single boost clock peaks at 4.5GHz. the Core i9-11900 appears to have an all-core boost of up to 4GHz. the Core i9-11900 is a 65W processor, but this is only the PL1 (Power Level 1) rating. the PL2 value is actually configured at 224W.

Both the Core i7-11700K and Core i7-11700 have the same core specifications as the Core i9-11900. In the case of the Core i7-11700K, the chip reportedly boasts a base clock of 3.4GHz and a single base clock of 4.8GHz. The all-core boost clock is a bit lower at 4.3GHz. unsurprisingly, the Core i7-11700K is rated at 125W PL1 and 250W PL2.

The base clock of Core i7-11700 is 1.8GHz, but the single boost clock reaches 4.4GHz. while the all-core boost clock stays at 3.8GHz. like Core i9-11900, Core i7-11700 also abides by the 65W PL1 and 224W PL2 limits.

The default XMP frequency for Rocket Lake-S is DDR4-3200. However, on an obscure B560 motherboard, DDR4-4133 memory can be used with the processor. This is a fascinating discovery, as it looks like Intel may have implemented memory overclocking on the B560 chipset. If true, this would be a revolutionary change, as chipmakers' smaller chipsets have historically been limited to the officially supported memory frequencies for that generation of processors. For example, existing B460, H470, and H410 motherboards are limited to DDR4-2933 memory modules, which is the official specification for Comet Lake-S processors.

Rocket Lake-S is known to wield the Cypress Cove core, and according to Intel, it will offer double-digit per-cycle instruction (IPC) improvements. On the graphics front, there were previous leaks that talked about four potential setups for the Gen 11 chip. The Rocket Lake-S SKU will feature Xe graphics with 32 EUs or 24 EUs, while the Lake Comet-S Refresh model will land on UHD graphics cards 630 and 610 with 24 EUs and 12 EUs, respectively.

Intel has set the launch date of Rocket Lake-S in the first quarter of next year. However, there are rumors that we may see an announcement at CES 2021 at the earliest.
