What the Core i5-460M is
The Intel Core i5-460M is a dual core Arrandale mobile processor from September 2010. It runs two Westmere cores at 2.534 GHz base with Turbo Boost to 2.8 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 460M matches the i3-380M on base clocks while adding Turbo Boost and threads for bursts. HD Graphics at 500 MHz with 766 MHz burst cover office displays.
Memory is DDR3-1066 in two channels up to 8 GB.
Socket and motherboard compatibility
The Core i5-460M fits Socket G1 with 988 pins. HM55 class boards boot it directly with a late 2010 BIOS. A BGA1288 soldered 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 the 520M or a Core i7 with 4 MB of cache. Beyond Socket G1 a move to Sandy Bridge needs a new notebook.
