clockspeed is not a particularly useful metric to evaluate a processor. warcraft is heavily dependent on the speed of a single core, vs the speed of multiple cores combined. but you can’t just compare one clock speed on one cpu to another, there is more to performance than just that clock speed, so you can only compare that if they otherwise have similar architecture. so unless you want to figure that out, just look at benchmarks. how well it handles multicore performance shouldn’t be ignored, though.
here’s a table showing laptop single core speeds, higher is better - i pasted those cpu’s below. the laptop itself can impact how the cpu performs too - for example how well the laptop handles heat can impact how much of and how long it can sustain that turbo clock speed before it throttles due to heat. https://www.cpubenchmark.net/singleThread.html#laptop-thread
