LPDDR5 5467 vs. 6400 vs. 7467 MT/s Memory Performance Benchmarks For Laptops

With the recently reviewed Star Labs StarFighter Ultra Linux laptop its BIOS allows for configurable memory speeds unlike many other laptop vendor BIOS implementations these days. Star Labs also made the default design decision to run the LPDDR5-7467 rated memory at LPDDR5-6400 speeds in the name of a balanced user experience for power/performance. So I was curious to run some benchmarks quantifying that power and performance impact of LPDDR5-6400 vs. LPDDR5-7467 plus tossed in LPDDR5-5467 testing as well as the third choice offered with this StarFighter Ultra laptop.
