Intel Core P8400

2C/2T · 25 W

The Core 2 Duo P8400 is a dual-core mobile processor from Intel's 45 nm Penryn generation, launched in mid-2008 for mainstream laptops. It runs at 2.26 GHz over a 1066 MHz front-side bus with 3 MB of shared L2 cache, operating within a 25 W thermal envelope that made it a common choice for thin-and-light notebooks of its era. It has no integrated graphics, relying on the platform chipset or a discrete graphics card for display output.
