A A gaming orientated measure of CPU speed that favours single over multi core performance. Intel i7-7700K ≈ 100%.

The effective CPU speed index measures performance with the following weights: 30% single-core, 60% quad-core and 10% multi-core. These weights, which are based on our analysis of hundreds and thousands of benchmarks, best represent typical CPU gaming performance with a single number. Consumer CPU performance does not scale well with core count. Extra cores work very well for server orientated workloads where there are typically several CPU intensive tasks running in parallel but for consumer and gaming workloads, where four cores or less are typically active, additional cores make little difference to real world performance. Beware the army of shills who would happily sell ice to Eskimos.
