Further Exploring The Intel Tiger Lake Core i7-1165G7 Performance On Ubuntu Linux
While the cause of the Ubuntu 20.10 change leading to the better single-threaded performance on Tiger Lake is still being explored, I did run some tests on Ubuntu 20.10 to see how the performance then compares to Ice Lake, Whiskey Lake, and Renoir results as featured in the initial article last week.
Due to the short time, here are those results from last week with the Ubuntu 20.10 run on the Core i7 1165G7 added in. Fresh tests with all of the laptops on Ubuntu 20.10 will be coming as time allows with continuing to explore the Tiger Lake Linux issues. In any case, these numbers provide some context for how Tiger Lake is performing against Ice Lake now in single-threaded workloads but also how the multi-threaded performance is now lower in many cases.
AI Benchmark as a multi-threaded, demanding test case is now slower on the updated Ubuntu stack. Rather than the i7-1165G7 outperforming the Ryzen 5 4500U, it falls behind the 4500U on Ubuntu 20.10. The uplift from Ice Lake to Tiger Lake shrank from 26% to 15%.
Similarly in other demanding CPU test cases, the lead over Ice Lake also shrank but still some healthy gains -- but in most tests, still not competing with the Ryzen 5 4500U / Ryzen 7 2700U.
