Intel ‘Rocket Lake’ Core i7-11700K and i9-11900 (ES2) processors have surfaced.
Bilibili.com leaked some more of the Rocket Lake-S engineering samples. The new Core i7-11700K and i9-11900 processors are allegedly second revision samples, released about a month after the first batch. ES1 samples were first distributed around June, while ES2 samples were shipped around August. The new leak from Bilibili seems to explain the differences between these examples.
Intel B560 motherboards with memory overclocking
Intel is allegedly following the path of AMD, which currently offers memory overclocking with the upper-mid-range B550 motherboard lineup. Intel said it was an option for the upcoming B560 series. This statement allowed the person who leaked the information from Bilibili to verify whether the samples tested support the memory’s built-in overclocking profiles (XMP).
Intel Core i9-11900 (ES2) QVYE
The QVYE instance is a non-K version of the 11900 CPU series. PL1 (power limit) is locked to 65W on this processor, while PL2 is set to 224W. The QVYE instance appears to support XMP profiles and Xe Graphics , set to 3200 MHz by default, as well as the PCIe Gen4 interface . The example has a clock speed of 1.8 GHz (base), 4.0 GHz (all-core turbo) and 4.5 GHz (single core turbo). Of course, these are not the processor’s final clock speeds. According to the leaker, the sample already seems to offer the performance of a Core i9-9900K or i7-10700K processor in this case.
Intel Core i7-11700K (ES2) QV1K
A second revision of the Core i7-11700K engineering sample appears to have a base clock of 3.4 GHz, an all-core turbo of 4.3 GHz and a single core turbo that goes up to 4.8 GHz. As expected from the K series processors, the PL1 value of this example is set to 125W and the PL2 value to 250W; these are usually the default values for unlocked K series processors. This example supports XMP as well as PCIe Gen4 set to 3200 MHz by default. Xe-Graphics seems to work as well as an internal iGPU.
Intel Core i7-11700 (ES1) QV1J
The example we already covered in our previous report was the first revision of the 11700’s non-K engineering sample. Unlike ES2 instances, ES1, PCIe Gen 4.0 and XMP profiles are not supported. However, the CPU supports onboard Xe Graphics. The QV1J instance features a 1.8 GHz base clock, a 3.8 GHz all-core turbo, and a 4.4 GHz single-core turbo.
Intel Xe Graphics on Rocket Lake CPUs
The leaker also shares some news about the integrated Xe Graphics in these examples. The current driver appears to support four different Xe iGPU models based on the Xe-LP architecture.
The leaker claims that although they are all listed as ‘UHD Graphics’, they should later be named Xe-32EU, Xe-24EU, UHD630 (RKL) and UHD610 (RKL). These are probably the driver’s code names. It is not yet clear what the final marketing name will be for these GPUs.
Intel is expected to announce 11th Generation Rocket Lake-S processors at CES 2021 next year. The processors will be Intel’s first generic series to support PCI Express 4.0 and feature Xe Graphics built in. According to rumors, Intel is expected to begin mass production of the 11th Gen series at the end of January. When it will be available for sale has not yet been confirmed, traders may not appear in stores until late February or early March.
