Computer Components FAQ

Q What is UBM Effective Speed?


A A percentage measure of real world component speed.
The UBM effective speed measures performance that's relevant to typical consumer use. For example, we de-emphasize deep queue depth data transfer and heavily multi-threaded CPU workloads as these metrics are not generally consumer orientated. The below list outlines the calculation for each component class.
CPU
The effective CPU speed index is weighted as 30% single-core, 60% quad-core and 10% multi-core.
Intel i7-7700K ~= 100%.
