Many years ago, overclocking was not limited by Intel/AMD like nowadays. As it is usual, when they see they can make extra money from the consumers by limiting their features to those who pay more, they don't hesitate to take advantage of that. In the last years, the Intel made it a little bit "impossible" for those who want to buy a CPU with unlocked multiplier. Intel was limiting that feature to the Extreme Edition CPUs. AMD took this as an opportunity to approach consumers with a feature their competition wouldn't give and so the AMD Black Edition CPUs appeared. AMD has been kindly enough to offer Black Edition products for each segment in the market, and that means you can find a BE (Black Edition) CPU for less than $100. Intel is striking back with a pair of new processors which feature an unlocked multiplier without the $999 tag. Today, Benchmark Reviews will analyze the Intel Core i5 655K Unlocked CPU which basically is a Clarkdale based 2-cores/4-threads processor with Intel HD graphics and specially aimed at overclockers. Is the unlocked multiplier good enough to pay that little extra or isn't it worth it? Is it better to overclock with multiplier or should I to raise the BCLK? Those answers and more will be covered as Benchmark Reviews tests the Intel Core i5-655K Clarksdale processor, model BX80616I5655K.
