So from the "leaks" this week we have the SD 8 Gen 4 at around 3011- 3069 Single core and 9080 - 9706 in multicore. So around 85% single core and 103% multicore compared to the A18 Pro.
The single core score IMO is pretty much imperceptible in day to day use. I have the iPhone 15 Ultra and tested a 16 next to it in the Apple store and it was no quicker for navigation and apple software. Now the SD 8 Gen 4 is faster on paper than the 17 Pro SOC. So I expect most people will have zero issues with this SOC. Both SOCs are fast enough for what 99% of people do with their phones.
I'm happy the A18 is faster "on paper" as it encourages Qualcomm to improve, and I fully expect they will next year.But I want to see that innovation in PCs and laptops or something like Dex on Galaxy phones. These chips are powerful enough to run desktop applications for many use cases.
