7700K overclocked to 5GHz, chip hits 100C

We've been hearing a fair bit about Intel's upcoming Core i7-7700K processor, which is the first Kaby Lake CPU everyone thinks of as it's the enthusiast SKU - but we don't have much in the way of performance numbers, until now.

There are now engineering samples and compatible 200-series motherboards floating around, with 'Zolkorn' leaking out some details on the 7700K. The 7700K processor in question was overclocked easily to 4.9GHz, requiring just 1.29V of power - but when you consider the Kaby Lake enthusiast CPU was hitting 100C... you might think twice before throwing down the OC gauntlet.

You can see in this screenshot the Core i7-7700K was hitting 4901.18MHz (49 x 100), while using just 1.26V of power.

Here the 7700K is overclocked to 4797.65MHz with 1.296V of power, and the chip bounces up to 100C - hovering in the mid-to-high 80s.
