What the Core i5-450M is
The Intel Core i5-450M is a dual core Arrandale mobile processor from June 2010. It runs two Westmere cores at 2.4 GHz base with Turbo Boost to 2.666 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 450M adds speed over the 430M at the same 35 W. The June 2010 date follows the Wikipedia processor table; the task list shows September, which likely reflects retail availability. 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 i5-450M fits Socket G1 with 988 pins. HM55 class boards boot it directly with a 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 a faster i5 such as the 520M, or a Core i7 with 4 MB of cache. Beyond Socket G1 a move to Sandy Bridge needs a new notebook.
