Intel’s Tiger Lake 10nm++ CPUs have suffered several leaks during this last phase of the year. The latest leak comes from the Chinese technology portal Zhihu, where a user has published performance metrics from a technical sample of Tiger Lake-U along with their specifications, showing a large increase in clock speed compared to Ice Lake processors.
Tiger Lake-U is 32% faster than Ice Lake by 15W
The tested chip shall be a Tiger Lake-U CPU with the designation ES2. This is the second technical revision of the Tiger Lake-U chips, which is expected to go into operation in 2020. The chip has a total of 4 cores and 8 wires and is expected to have a boost speed of 4.30 GHz on one core and 4.00 GHz on all cores. No further information like cache and iGPU is mentioned, but the Tiger Lake-U CPU as compared to an Ice Lake-U processor.
The Ice Lake-U CPU was a 15W i7-1065G7, which we know is also a 4-wire 8-wire model with a 1.30 GHz base clock, a 3.90 GHz boost clock, and a 3.50 GHz all-core boost clock. Tiger Lake-U’s technical samples were tested at both 15W and 28W, which led to many different results.
The performance results:
In SPEC speed tests the 15W Tiger Lake-U chip is about 17% faster than the Ice Lake-U processor. The 28W variant is about 31% faster than the Ice Lake-U chip and about 18% faster than the 15W configured Tiger Lake-U processor. In SPEC rate tests, the 15W configuration of the Tiger Lake-U is about 26% faster than the Ice Lake-U chip, while the 28W variant is about 60% faster than the Ice Lake-U chip and about 30% faster than the 15W Tiger Lake-U chip.
The CPU should have a very high energy efficiency compared to Ice Lake-U, which is made possible by the second-generation 10nm node.

So far we haven’t seen 6- or 8-core CPU configurations for the Tiger Lake U processor series, but a 6-core variant seems to address AMD’s Renoir, Ryzen 4000 APU series, which is expected to offer 8-core, 8-threaded models in just 15W TDP. The H-series parts are even better with 8-core, 16-core configurations.
Intel Tiger Lake processors are expected to arrive in 2020 and will have some architectural changes, starting with the core switch to Willow Cove.
