Tiger Lake performance profile

AnandTech's (SPEC ST performance) review is here: anandtech.com/show/16084/intel-tiger-lake-review-deep-dive-core-11th-gen/8

All of TigerLake's extra performance over IceLake is due to higher clocks. And it significantly outperforms the Zen 2 based AMD Renoir chip (Ryzen 7 4800U). However not all is good: TigerLake experiences a noticeable IPC regression compared to IceLake. The memory subsystem is unable to keep up with the higher clocks, and the reworked cache is not enough.

And it just barely beats Apple's A13 despite using significantly more power. Makes you think the A14 based Mac coming later this year will blow past Intel's best CPU microarchitecture in single threaded integer performance.
