Intel Announces Rocket Lake-S, 11th Generation Core Chips for Desktops | Computer

It was the beginning of September 2020 when the Intel introduced the first 11th generation Core processors, but only for notebooks. Six months have passed and now the missing models are among us: this Tuesday (16), the company announced the chips 11th generation core for desktops (Rocket Lake-S), with emphasis on octa-core Core i9-11900K.

The official announcement of the new chips was already expected for this month of March. In October of last year, just over a month after Intel announced the 11th generation Core models for laptops, the company signaled that it would confirm the desktop versions by the end of the third quarter of 2021.

At the time, very few details were revealed. Apparently, Intel only made the statement as far as possible to overshadow AMD’s announcement of the Ryzen 5000 desktop chips (Zen 3 architecture) the next day.

Now the details are already known. Altogether, Intel announced 19 Core 11th generation processors for desktops (and some models still based on the previous generation). The Rocket Lake-S line, for example, supports USB 3.2 Gen 2, Wi-Fi 6E, HDMI 2.0, Thunderbolt 4 and – finally! – PCI Express 4.0.

The new line also supports DDR4 memories up to 3,200 MHz, more features for overclocking (including memory overclocking on motherboards based on H570 and B560 chipsets) and HUD Graphics 750 and 730 graphics, both GPUs based on Intel architecture X and.

Without further ado, here’s the list of Rocket Lake-S chips. Note that models with the letter ‘K’ in the name are unlocked for overclocking; chips with the letter ‘F’ do not have an integrated GPU; the letter ‘T’ signals for options with low TDP:

There are also novelties in the less powerful lines, but in these, Intel has chosen to keep the chips within the 10th generation Core family:

More performance, including graphics

The new 11th generation chips are based on an architecture named Cypress Cove, a kind of adaptation of the 10-nanometer Sunny Cove architecture to a 14-nanometer manufacturing process.

However, the detail that draws the most attention in the new processors is the fact that they have no more than eight cores. The previous generation, the Comet Lake-S chips, has up to ten cores and 20 threads, like the top of the line Core i9-10900K.

Despite this, Intel talks about more performance. According to the company, Rocket Lake-S chips have gained 19% in IPC (acronym in English for “instructions per clock cycle”) and up to 50% more graphics performance compared to the previous generation.

In Flight Simulator and Grid 2019 running at 1080p, for example, the Core i9-11900K showed 14% and 8% more performance, respectively, compared to the Core i9-10900K in a test carried out by Intel itself.

In the United States, sales of the new chips start until the end of the month. For now, there is no information about launching in Brazil.
