LGA 1200 Intel Rocket Lake processors: SKUs and specs
The March 2011 release of Rocket Lake processors, the 11th generation Intel Core for desktop is closing in. But leaks have already painted a good picture of their specifications: we have an overview of Rocket Lake SKUs from Core i5-11400F to octa-core i7-11700K and i9-11900K chips, even with parameters and clock speeds. Rocket Lake cores have 18% higher IPC, so single-threaded performance should be significantly improved.
We have already talked about the highest-end Rocket Lake processor, the octa-core Core i9-11900K, separately. The database of Ashes of the Singularity revealed that it has a base clock of 3.5 GHz and a 125W TDP and 16MB L3 cache have been confirmed. There was also information that its maximum all-core boost is 4.8 GHz. For a single-core loads, the maximum clock speed should be up to 5.3 GHz, but that probably involves Thermal Velocity Boost and Turbo Boost Max 3.0, i.e. this depends on core temperature meeting certain limits and the use of the favored core.
Information about other models has now appeared from several sources, so we can compile a table of most likely all the coming chips (not involving the 35W T-series). Unlocked models plus a hexa-core i5-11400 were shown by twitter leaker nicknamed Harukaze5719. It should be noted that the author himself calls it “rumor”, so not everything in his table of specs is guaranteed to be definitive. It is possible that part of it is speculative. For example, some clock speed values could turn out to be different in the end.
In addition to this source, we also have a list of models from the user Momomo_us, which also includes 65W processors: Core i9-11900, Core i7-11700 (both octa-core) and hexa-core i5-11400. It seems that for each model, Intel also plans to offer a “KF” version without graphics (or just “F” for locked models). You will get the opportunity to save a little with those. The same leaker also found the specs of two of the locked models. We also learned that Intel has not changed the TDP from his information – unlocked models are 125W and the usual locked ones will be 65W (but the power draw limit during boosting will be up to 250 W).
You can see the full set of Rocket Lake processors below. The values for which there is a clear source that we consider credible are bolded. The values that are not as confirmed are left unbolded (this way it should be clearer which values are more trustworthy). We assume that the F and KF models will not differ in any way except for the GPU being deactivated, even though this has not been confirmed yet.

Comet Lake refresh will offer cheap CPUs
The list of Rocket Lake processors ends with the Core i5 on the low side. The 11th generation desktop Core family will also include cheaper Core i3, Pentium and Celeron models, but these will be produced from Comet Lake silicon, the same chips as in the 10th generation. So they will retain the old Skylake architecture (and the GPU architecture will be Gen9 from Skylake and Kaby Lake as well, respectively). This also means that these processors will not support HDMI 2.0 and PCI Express 4.0, while Rocket Lake will.
From the leaked information we also know that Intel will offer the Core i3-11100, i3-11300 and i3-11320 models for example, but we are still missing specs for those. They probably shouldn’t be too different from their predecessors (i3-10320/10300/10100).
To be released in two months (and some?)
Rocket Lake processors, according to previous reports should be released in March, which is not officially confirmed however – Intel has so far only specified the launch date to be in Q1 2021. Recently however, new reports have come up stating that the motherboards based on the Z590, B560 and H510 chipsets should be released earlier, on January 11 (note that Rocket Lake will also work in old motherboards with the 400-series Intel chipsets).
But this only applies to motherboards. According to the same source, the processors themselves are still planned to be released later – at the end of February at the earliest and perhaps in the following month, which would matche what the earlier rumor said about the launch date.
