Production parts

Core i5-875K is one of the first not overly expensive Intel non-Extreme microprocessors with unlocked clock multiplier. According to preliminary specifications, unlocked multiplier is the only difference of this CPU from Core i7-870, and in all other aspects they are nearly identical: 45nm Lynnfield core, quad-core design, 2.93 GHz core frequency, shared 8 MB level 3 cache, and the latest Intel technologies including HyperThreading and Turbo Boost. It is expected that the Core i7-875K part will be launched together with Core i5-655K in the first half of June 2010. Official price for the i7-875K is not known yet. If the only leaked pre-order price is correct, then official price will be in the range $340 - $370.
Intel Core i7-920 (AT80601000741AA / BX80601920 / BXC80601920)

Official launch of the Core i7 microprocessor family in November 2008 included first three members of the family - i7-920, i7-940 and i7-965 Extreme Edition. The slowest from these three processors, and so far the slowest from the whole i7-9xx lineup, is the Core i7-920. Despite of its relatively low core frequency, "just" 2.67 GHz, the i7-920 performs as good of better than Core 2 Quad Q9650, the fastest Core 2 Quad microprocessor running at 3 GHz. Thanks to HyperThreading feature, Core i7-920's advantage is especially impressive in heavy multi-threaded media applications - in some applications the Core i7 processor is up to 35% faster than the Q9650. Performance of the i7-920 in games is less impressive. Depending on the game, the CPU may be faster or slower than the Q9650 by up to 10%, and on average it performs on a par with the Q9650.
