What the Core 2 Duo E8600 is

The Intel Core 2 Duo E8600 is the fastest Core 2 Duo, a 3.333 GHz dual core from August 2008. It runs two Wolfdale cores at 3.333 GHz with no turbo, so 2 cores give 2 threads. Cache is 6 MB of shared L2 on a 45 nm process. Power is rated at 65 W on LGA 775.

The E8600 tops the Wolfdale desktop line in stepping LB9L on a 1333 MT/s bus. It exists because Intel stretched the 6 MB dual-core design to 3.333 GHz for buyers who wanted top dual-threaded speed without moving to a quad.

Socket and motherboard compatibility

The E8600 drops into LGA 775 boards with DDR2 or DDR3 memory and a BIOS that lists late-2008 Wolfdale parts, such as G41 and P45 boards. It pairs with mainstream 4 series chipsets. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR2 and DDR3 through the board chipset in two channels.

A 1333 MT/s front side bus ties the CPU to the chipset. PCIe Gen 2 slots hang off the chipset.

Cooling is any 65 W rated LGA 775 heatsink on the 72.5 × 72.5 mm mount, with Enhanced SpeedStep trimming draw at idle.

Upgrade paths

On LGA 775 the E8600 is the dual-core ceiling, so the moves are the Intel Core 2 Duo E8500 at 3.16 GHz for a cheaper 6 MB part, or a Core 2 Quad where threaded work matters. Beyond LGA 775 a move to a newer platform needs a new board and memory.
