During the Arm DevSummit event held in October last year, Intel revealed a much-awaited piece of information when it officially confirmed that its 11th generation “Rocket Lake” desktop CPUs will be coming out. eyes right in the first quarter of 2021.

Now, after countless rumors and even controversy, Intel has finally released details on its “strategic” 11th generation desktop processors, with codename Rocket Lake-S.

First of all, these processors are still being developed on the “familiar” 14nm process. This is clearly something that many people, even Intel fans, are unhappy about. But don’t let out a bitter word, because there will also be a lot of new, cool improvements that Intel brings to Rocket Lake-S. In it, typically the emergence of a completely new architecture, bringing the ability to improve up to 19% IPC (instructions per clock cycle).

New structure

The new chip models also come with a completely new integrated graphics card, called UHD Graphics 750 and developed on the highly appreciated Iris Xe architecture. Intel confidently promises this new GPU will deliver 50% better performance than the previous generation. In addition, artificial intelligence is also an aspect of Intel’s attention on Rocket Lake-S with the introduction of new AI features with Intel Deep Learning Boost.

For some other noteworthy improvements, Rocket Lake-S will support up to 20 PCIe 4.0 lanes, while its predecessor only supports PCIe 3.0, and owns half the bandwidth. The new chip line will also support faster DDR4-3200 memory, integrated HDMI 2.0, 10-bit AV1 and 12-bit HEVC support, and more overclocking features (memory overclocking support on H570 and B560 chipsets).

Although Rocket Lake-S uses the same LGA 1200 socket as the previous Comet Lake-S, it uses a new 500 series chipset (some older motherboards are still supported through firmware updates). . Rocket Lake-S comes with built-in support for Thunderbolt 4, Wi-Fi 6E, 20Gbps USB 3.2 Gen 2×2, etc.

In Intel’s internal tests, at 1080p settings, the Core i9-11900K beat its predecessor in Total War: Three Kingdoms titles by 13%, Gears 5 at 9%, Grid 2019 at 8%. and the Microsoft Flight Simulator 14%. But more importantly, when compared to the AMD Ryzen 9 5900X, the Core i9-11900K leads 10% with Total War: Three Kingdoms, 3% on Gears 5, 6% on Grid 2019 and 11% on Microsoft Flight Simulator.

The processors will hit shelves this month and have a maximum selling price of $ 539 for the flagship Core i9-11900K. While the lowest-end model, Pentium Gold 6405T, will cost 64 USD.
