Although the new Sandy Bridge architecture may not be revolutionary, it is a much improved version of Nehalem as it seems to do everything a little better. When compared to the Clarkdale Core i5 661 processor which we reviewed exactly a year ago, the...

At Rs.13,800, the Core i7 2600K isn’t exactly cheap, but for the kind of performance it delivers and its feature set, it’s not bad. Just a year ago, if you wanted an Intel CPU with an unlocked multiplier, you’d have no choice, but to go with their...

A brand-new core design enables the chips to do more at a given clock speed than their predecessors. The humble Core i3-2120 runs at a slightly slower 3.3GHz frequency than the mid-range i5-660 from Intel's older 1156 platform, but it achieved higher...

The Intel Core i7-2600K is a worthy successor to the i7-860 and i7-920 chips at default clock speeds. If Sandy Bridge permeates the entire market, the (relatively) lower-end LGA1156 motherboards and processors can walk away. In fact, even the X58...

The Intel Core i7-2600K processor is a worthy successor to the i7-860 and i7-920 at default clock speeds. On balance, paying about the same amount for a higher-midrange processor and getting a 25 per cent increase in performance (besides...
