Intel is expected to bring the first update to it high-end Sandy Bridge processor lineup with the introduction of the Core i7-2700K CPU, which was just confirmed to have a base operating frequency of 3.5GHz.

The upcoming Intel chip was recently listed by motherboard maker Biostar in the CPU support list for one of its LGA 1155 motherboards.

Besides the improved clock speed, the most important feature brought by the Core i7-2700K is its unlocked multiplier design, as this means overclockers will be able to push the operating frequencies of the processor further than Intel's specifications.

When it designed the Sandy Bridge architecture, Intel decided to take a different route as far as overclocking is concerned and it locked the BCLK of the CPUs.

Pricing and the release date is as of yet unknown.
