Intel Core 2 Duo T9550

2C/2T · 35 W

The Intel Core 2 Duo T9550 is a high-end dual-core mobile processor introduced in December 2008, slotting between the T9400 and T9600 in Intel's 45 nm Penryn range. Two cores run at 2.66 GHz with 6 MB of shared L2 cache on a 1066 MHz front-side bus, within the standard 35 W mobile thermal envelope. It is essentially a mid-cycle speed bump on the Centrino 2 platform, offering slightly more headroom than the 2.53 GHz T9400 at the same power and cache. Enhanced Intel SpeedStep steps the cores down to 1.6 GHz and then 800 MHz under light load, and Deep Power Down cuts idle draw further. Intel 64 and SSE4.1 are supported. The processor came in a 478-pin micro-FCPGA package for Socket P as well as a soldered 479-ball micro-FCBGA version, for use with Mobile Intel 4 Series Express chipsets.

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.
