Performance Summary

With CPU waterblocks, both thermal performance and liquid-flow restriction are important metrics. Unlike radiators where component liquid-flow restriction is not as big a factor in the loop's overall flow rate, the CPU block choice will impact average flow rate a lot and can thus not be ignored. In order to quantify relative performance for a CPU block thus, a normalized (% based) data set was created, with 70% weightage given to thermal performance and 30% weightage given to liquid-flow restriction. The data set created was thus plotted with the subject of this review at 100%.



With there being little difference when it comes to absolute thermal performance, it is no wonder then that the Bitspower Summit EF-X has a good showing in the relative performance charts. This is more to do with the low liquid-flow restriction, so please keep that in mind.

Performance per Dollar

The prices were taken from Performance PCs in the USA, with all numbers reported in USD. For products no longer available, the last available and reasonable price point was considered.



With pricing considered, the Summit EF-X suddenly no longer looks that attractive. Bitspower has always had a "brand tax" if you will, with their products often costing more than others in most markets. The USA market is no different with a lot of products that perform similarly but cost less, offering better value for your money.
