An Apple "iPhone16,1" was put through the Geekbench 6.2 gauntlet earlier this week—according to database info this pre-release sample was running a build of iOS 17.0 (currently in preview) and its logic board goes under the "D83AP" moniker. It is interesting to see a 16-series unit hitting the test phase only a day after the unveiling of Apple's iPhone 15 Pro and Max models—the freshly benched candidate seems to house an A17 Pro SoC as well. The American tech giant has set lofty goals for said flagship chip, since it is "the industry's first 3-nanometer chip. Continuing Apple's leadership in smartphone silicon, A17 Pro brings improvements to the entire chip, including the biggest GPU redesign in Apple's history. The new CPU is up to 10 percent faster with microarchitectural and design improvements, and the Neural Engine is now up to 2x faster."
7600K - 1481 ST 13600K - 2654 ST 13700K - 2820 ST 13900K - 2955 ST
So to answer the question something like an 80% improvement over 2016, roughly 2x if you compare it to a 2016 i5. And the 13900K does have the highest single thread performance in the 13th-gen models from what I can tell.
