It is two times higher than that of 10-nanometer Ice Lake.
Intel formally announced Tiger Lake mobile processors at CES 2020 last week. Then there were no special technical details, but they arrived in time: one of the promising Tiger Lake appeared in the 3D Mark database, and something in its characteristics is very pleasing.
Something is frequency. The base is 2.7 GHz! For comparison, the 14-nanometer Core i7-10510U has a base frequency of 1.8 GHz, while the 10-nanometer Core i7-1065G7 has only 1.3 GHz! It turns out that the difference between similar models (all in this comparison are quad-core with multithreading support) of the two families – Ice Lake and Tiger Lake – 1.4 GHz in favor of the latter. That is more than twice! In this situation, it is logical to expect a significant increase in productivity.
The Tiger Lake processor tested in 3D Mark will have to deal with the eight-core AMD Ryzen 7 4700U. It operates at a frequency of 2.0-4.1 GHz and does not support multithreading. Apparently, the maximum frequency for this nameless (so far) representative of the Tiger Lake line will be higher.
