Processors Intel Tiger Lake have not yet entered the market and exist only in the form of engineering solutions. But judging by the leaks, they are now provide overclocking in turbo mode up to 4 GHz for all cores.
For comparison, the fastest processor of the tenth generation today Intel Core i7-1065G7 rulers Ice lake the frequency reaches 3.5 GHz on all cores and 3.9 GHz on one. So the serial Tiger Lake performance can be even better.
However, there is nothing surprising here, because Ice Lake and Tiger Lake were created using a 10-nanometer process technology (more precisely, 10-nm + and 10-nm ++, respectively). Therefore, the increase in frequencies is unlikely to be a surprise.
In addition, Tiger Lake will use improved architecture. Willow cove with 96 executive units of the graphic system Xe. The release of the new product is expected to be released in the first half of 2023. All this suggests that laptops based on these processors will be very productive.
