Intel Kaby Lake Core i7-7700K Sample Tested
No embargo is sacred, that's what Toms Hardware must have figured as the posted benchmarks on an Intel Kaby Lake Core i7-7700K Sample.
The chip used is not an engineering sample, so they will not confirm that it is a retail part (uh-huh). They used the processor on an Gigabyte GA-Z170X-Ultra Gaming board. The CPU clocks in at a 4.20GHz core frequency with 4.50GHz max turbo boost with a TDP of 95W. That's 100 More then a i7-6700K's 91W.
anted to test!

Judging from the results the processor draws a bit more power opposed to the 6700K. The benchmark results are close to each other, the increased turbo bin frequencies obviously does the job. Overclocking, the 7700K reached a 4.8GHz overclock at 1.3v, again very similar to all other Intel processors in this category.

There is one - the price of the new units will be 100-150 EUR higher than the predecessors

So Intel now releases CPUs with no difference at all to the previous gen. What's next? A cpu which has lower performance from the previous gen?

Not even 5% performance increase?? Is this legit?
