Intel at CES 2021: Core i9-11900K, Z590 motherboards and ultraportable gaming laptop CPUs

The first of the big three chip-makers to have their CES 2021 press conferences, Intel has had a packed day of announcements. The company teased their next flagship desktop chip, the Core i9-11900K, as well as 500-series motherboards and 11th-gen H-series CPUs for laptops. Here’s what you need to know – starting with the 11900K.

In some ways, the 11900K feels like more of a successor to the Core 9900K than the 10900K, as it drops back down from 10 cores and 20 threads to eight cores and 16 threads. However, this decrease in core count should be compensated for by an up to 19 per cent quoted improvement in instructions per clock (IPC), an important measure of single-core performance – and an area where AMD made significant strides with their Ryzen 5000 processors.

This larger-than-normal IPC uplift in Rocket Lake S comes from the use of Cypress Cove cores, which debuted in Intel’s 10nm Ice Lake laptop chips and now have been back-ported to that familiar 14nm process Intel has been using for some time now in its desktop CPUs. Frequencies on the 11900K are on par with the 10900K too, with the new processor being capable of boosting to up to 5.3GHz on a single core or 4.8GHz on all cores with Thermal Velocity Boost.
