What the Core i5-580M is

The Intel Core i5-580M is a dual core Arrandale mobile processor from September 2010. It runs two Westmere cores at 2.667 GHz base with Turbo Boost to 3.333 GHz, with Hyper-Threading for four threads. Each core carries 256 KB of L2 cache with 3 MB of shared L3 cache. Power is rated at 35 W.

The 580M matches the 560M on base clocks with a higher turbo peak for single threaded bursts. HD Graphics cover office displays. The same model ships socketed and soldered; this page covers the socketed package.

Memory is DDR3-1066 in two channels up to 8 GB.

Socket and motherboard compatibility

The Core i5-580M fits Socket G1 with 988 pins. HM55 class boards boot it directly with a late 2010 BIOS. The BGA1288 version needs its own board.

The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Intel Core i5-480M page shows a faster i5 on the same socket.

Memory, PCIe and cooling

Memory is DDR3-1066 in two channels up to 8 GB.

PCIe 2.0 x16 comes from the package.

Cooling uses the vendor heat pipe assembly rated for 35 W.

Upgrade paths

On Socket G1 the upgrade is a Core i7 with 4 MB of cache. Beyond Socket G1 a move to Sandy Bridge needs a new notebook. This page covers both task rows for the 580M.
