50% faster multicore performance compared to my M1 MacBook Air and exactly the same single-core. Fairly disappointing, I would have expected the higher memory bandwidth to contribute something. I've found the STREAM benchmark correlates very well with the kind of performance I need for databases and the like, and in the past upgrading RAM from DDR4-2700 to DDR4-3200 gave a ~10% improvement on Geekbench scores under Linux. The only reason to get one of the new MBPs is the higher RAM capacity (and the amenities of the new chassis, of course), not CPU performance.
