AMD has 16 cores, Apple has 18, Qualcomm has 18, Nvidia N1X has 20, and Intel has 24. All else being equal you actually want as few cores as you can get away with because that's less likely to be limited by Amdahl's Law. Arguably Intel/Nvidia CPUs are poorly designed and benchmarks have no obligation to accommodate them.

(I'm not counting high-end workstation/server CPUs because, as others in this thread have explained, Geekbench isn't intended for them.)
