Intel Core 2 Extreme X9100

2C/2T · 44 W

The top of the mobile Penryn line: an unlocked dual-core Core 2 Extreme running at a fixed 3.06 GHz with 6 MB of shared L2 cache on a 1066 MHz front-side bus. Built on Intel's 45 nm process for Socket P notebooks, it traded a 44 W thermal envelope for desktop-class clock speeds in 2008 gaming and workstation laptops.

OS support

Windows: Windows 10
Linux: UbuntuFedoraArch Linux
Notes: Windows 11 is out of reach: Penryn is far below the 8th-generation floor on Microsoft's supported-processor list and the platform offers no TPM 2.0 or Secure Boot. Windows 10 and the mainstream Linux distributions still install, because they are built for the x86-64 baseline, but the CPU has no SSE4.2 or POPCNT, so any software that requires x86-64-v2 or newer will not run. ChromeOS Flex does not cover hardware of this era.
