Probably Tiger Lake-U. I definitely believe M1 is faster.
Apple has a history of pretending things like Nvidia or Ryzen don't exist when it suits them so I'm sure there will be gotcha benchmarks down the line.
Apple also compared against "best-selling PCs" several times, but the best-selling PCs are the cheapest junk so obviously Macs will be faster than those.

> Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip, as well as production 1.7GHz quad-core Intel Core i7-based 13-inch MacBook Pro systems, all configured with 16GB RAM and 2TB SSD. Open source project built with prerelease Xcode 12.2 with Apple Clang 12.0.0, Ninja 1.10.0.git, and CMake 3.16.5. Performance tests are conducted using specific computer systems and reflect the approximate performance of MacBook Pro.
That's.. kind of weak. How many other perf tests did they throw away before taking this one because it showed so well? I guess we'll see the real-world benchmarks when people get their hands on them.
Geekbench is not a _great_ benchmark, but it's common enough that we could use it to roughly compare.
EDIT: Apparently there are Geekbench results that are unofficial that suggest it's faster than current MBPs, but we'll have to see.
“World’s fastest CPU core in low-power silicon”: Testing conducted by Apple in October 2020 using preproduction 13-inch MacBook Pro systems with Apple M1 chip and 16GB of RAM measuring peak single thread performance of workloads taken from select industry standard benchmarks, commercial applications, and open source applications. Comparison made against the highest-performing CPUs for notebooks, commercially available at the time of testing."
So, "Comparison made against the highest-performing CPUs for notebooks, commercially available [one month ago]". I guess there could be wiggle room on interpreting "highest-performing", but this seems pretty good.
