英特尔 Lunar Lake CPU 在 Linux 上的性能提升
文章测试了英特尔 Lunar Lake CPU 在 Linux 上的性能变化。
对比了搭载英特尔酷睿 Ultra 7 258V 处理器（8 核心，最高睿频 4.8GHz，17W TDP）的联想 ThinkPad X1 Carbon Gen 13 Aura Edition，在 Ubuntu 25.04 (Linux 6.14 内核) 和 Ubuntu 26.04 (Linux 7.0 内核) 上的表现。
测试发现，随着内核、编译器（GCC）和 Mesa 图形驱动等软件的更新，Lunar Lake CPU 的性能在过去一年内有所提升。
此次测试旨在了解使用较旧 Ubuntu 版本的老用户升级到 Ubuntu 26.04 LTS 后，能够获得多少性能增益。

Recently I ran benchmarks looking at the Xe2 graphics performance gains on Intel Lunar Lake over the past year with what's shipped by Ubuntu and comparing against our original tests of the Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition. With those Lunar Lake iGPU benchmarks out of the way, here is a look at how the Lunar Lake CPU performance has evolved on Linux since April 2025.
With the prior testing focused on the Xe2 iGPU gains with Lunar Lake from Ubuntu 25.04 to Ubuntu 26.04, this article is looking at the CPU side. The Lenovo ThinkPad X1 Carbon Gen 13 Aura Edition for this testing then and now is done with the Intel Core Ultra 7 258V, the 8-core part with a 4.8GHz maximum turbo frequency, 17 Watt TDP, and 32GB of memory.
The original tests of the Core Ultra 7 258V / ThinkPad X1 Carbon Gen 13 were done last April with Ubuntu 25.04 with the Linux 6.14 kernel, Mesa 25.0, GCC 14.2, and other default components. With the newly-released Ubuntu 26.04 we are now up to the Linux 7.0 kernel, GCC 15.2, Mesa 26.0, and the GNOME 50 desktop, among other software upgrades in this new Ubuntu Long Term Support version.
