Over the Christmas holidays (and shortly before) there were numerous sightings of the next generation of processors from AMD and Intel. First of all, there are signs of the imminent launch of the Intel Rocket Lake processors, as more and more samples are apparently in circulation. Intel has already officially announced this for the first quarter 2021 and also given the first details.

The 11. Core generation from Intel will use the existing LGA socket 1200 of the Comet Lake generation. They will use up to eight of the new Cypress Cove cores and should clock significantly more than 5 GHz for the high-end models. The most important new feature of the platform are four additional PCI Express lanes, all of which will also be upgraded to the 4.0 standard. All other, so far official details can be found in the message to Intel’s announcement.

The performance of the Rocket Lake processors cannot really be estimated at the moment. But Intel should be able to catch up with AMD again – at least where AMD had a small lead with the Zen 3 architecture. At the moment, however, there are no reliable figures for performance.

The mainboard manufacturers are currently preparing for the launch of Rocket Lake-S for the existing LGA 1200 – mainboards. The first BIOS updates are already being distributed and carry out the 11. Core Generation as supported models.

Alder Lake-S still raises many questions

With Alder Lake (and Alder Lake -S for the desktop), Intel is transferring the strategy of Lakefield processors to a larger product range. Alder Lake-S will be the successor to the Rocket Lake processors mentioned in the first section. The hybrid design will no longer only be used in the ultra-mobile area, but also on the desktop.

Up to 16 Cores should use the Alder Lake S processors. So far there has been talk of an 8 + 8 configuration – so eight high-performance cores should be combined with eight particularly efficient ones.

More and more samples appear for Alder Lake-S too. However, one should not accept the details of the information read out as complete and secure. The cores seem to be following the path that Intel has taken with Sunny Cove, Willow Cove and the Atom designs. This can be seen from the size of the cache.

The question of which cores support simultaneous multithreading (SMT) and which do not remain open. At Lakefield, Intel deactivated the SMT for the Sunny Cove core because the small Atom cores did not support this. For the Alder Lake S processor shown here with 16 cores, support for 24 threads listed. Eight large cores with SMT come on threads, the eight smaller cores must therefore manage without SMT.

The Alder Lake S processors are expected at the end of 2017 and lead with the LGA socket 1700 a new platform. In addition to DDR4 and PCI-Express 4.0, it probably also supports DDR5 and PCI-Express 5.0. So far, Intel has not yet commented on which architectures or cores are used. According to the latest information, this should be Gracemont for the small cores and Golden Cove for the large cores.

Cezanne and Lucienne for notebook and desktop

AMD will present the next generation of APUs at the virtual CES in early January. As Cezanne and Lucienne, they use Zen 3 and Zen 2 cores and an integrated Vega graphics unit. By using the Zen 3 architecture, AMD of course makes a big leap in CPU performance. First benchmarks show an increase of up to 25%. In the TDP classes, AMD of course remains at the level of its predecessors.

Cezanne apparently also serves as Renoir’s successor – at least for OEM use. It remains to be seen whether Cezanne, like Renoir, will be withheld from the retail market. First of all, Cezanne and Lucienne are expected for the notebooks.
