Intel opened its back door and shuttled out a refresh of its chips without so much as a phone call, typical! Three desktop Core i5 chips made their way into the big bad world, the i5-2550K replacing the i5-2500K, the i5-2450P replacing the i5-2400 and the i5-2380P replacing the i5-2320. There's a suspicion that the P that follows the two latter models means the GPUs have been disabled / removed to differentiate the price. The four Celerons, two low-voltage, two ultra-low voltage similarly replace older models, from the $70 B720 (replacing the B710) through to the $134 Celeron 867, supplanting the 857. If that list of numbers hasn't whetted your appetite for, erm, more numbers, then head on past for detail so comprehensive you'll have to make sure it's covered by your HMO.
