From bb016ddb9061a89c72448f4dbe356350f5cac0ea Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 15 Jun 2026 18:48:56 +0200 Subject: [PATCH] arm64: dts: qcom: sm8650: update the cpus capacity-dmips-mhz After some more advanced benchmarks with Integer, Floaring Point, Encryption, Compression, NEON, ... on the A520, A720 and X4 cpus, the median gain with the same frequency range is: - 281% of A720 over A520 - 126% of X4 over A720 When adjusted with the frequency delta, we get better values describing the difference in capacity, showing the weakness of the A520 designed for very small tasks while the A720 and X4 are much more powerful.
