Production microprocessors

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
Author: gshv
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.

Additional information

Integrated HD graphics on Intel microprocessors was introduced in Westmere group of families, and it was significantly improved since then. With more and more features added to each generation of integrated GPUs, it becomes more difficult to find out what features are supported on specific integrated graphics unit. The purpose of this article is just that: to provide a comprehensive listing of all supported features for all generations of integrated Intel GPUs.

This overclocking example explains basic steps, required to overclock Sandy Bridge-base microprocessors. The example provides quick overview of different BIOS settings, and includes a number of benchmark results, that compare Sandy Bridge CPU (Core i7-2700K) at stock and overclock frequencies.
