With the aim of enhancing the chances of its 'most advanced chip architecture' to penetrate into the mainstream market, Intel Monday announced new, affordable Core i7 800-series chips, along with an even more economical Core i5 CPU!

Going by the initial tests, Intel's new Core i7 800-series CPUs - the $562-priced Core i7 870 and the $284-priced Core i7 860 - are the mid-range substitutes of the company's most advanced and high-end Core i7 900-series chips, in terms of both technical aspects as well as performance; while the new entry-level Core i5 750 is apparently the best buy at its rather affordable $196 price-tag.

Both the new Core i7's, the 2.93GHz Core i7 870 and the 2.8GHz Core i7 860, have a double-channel RAM and need two sticks of DDR3 at a time, as against the triple- channel RAM and three DDR3 sticks required by the top-of-the-line Core i7 900's.

Meanwhile, the solitary Core i5 chip, which also has two-channel memory limit, also boasts the Hyperthreading capability.

In addition, all the three new chips run Intel's latest P55 chipset and LGA1156 socket - requiring the purchase of a new motherboard -, each with different incarnations of the most noteworthy features of the Core i7 900-series. Moreover, the new Core i7 800-series CPUs and the Core i5 750 also support the overclocking functionality, or 'Turbo Boost', which yet another Core i7 900-series' feature!
