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…
The Star Labs StarFighter Ultra Linux laptop offers configurable memory speeds, allowing users to choose between LPDDR5-5467, LPDDR5-6400, and LPDDR5-7467 rated memory. In this review, the author tested the power and performance impact of each option, alongside an 8 x 8GB LPDDR5-7467 configuration, using the Intel Core Ultra 9 285H Arrow Lake processor, 1TB Samsung 990 EVO Plus SSD, and integrated Intel Xe graphics.
The benchmarks were conducted on a Coreboot-powered system, and an external WattsUp Pro power meter measured the total AC power consumption throughout the testing process.
