The secret of Intel Kaby Lake processor performance improvement: frequency up to 4.5GHz

If Intel ’s Tick-Tock strategy has not stopped, then we should see a 10nm process processor this year, but in fact, the seventh-generation Intel processor Kaby Lake launched by Intel this year is still 14nm process, and the architecture is not much larger than Skylake. Variety. If Kaby Lake has only this ability, then it will be difficult to attract consumers to upgrade, but Intel has already demonstrated the confidence of honey juice earlier, thinking that although there is no process upgrade, they can still bring considerable performance improvements.
According to the latest news, Intel ’s means to improve Kaby Lake performance may be to increase the frequency. The flagship Core i7-7700K can reach a maximum frequency of 4.5GHz.
Last weekend there was a test of the Kaby Lake processor CPU and core performance. From the results, the CPU performance did improve, and the core performance was even greater. Although this is only a mobile version and does not represent the desktop version of Kaby Lake, according to this trend, Intel still has to show a little sincerity to attract consumers to upgrade, otherwise Kaby Lake will be meaningless.
So, with little change in process technology and architecture, what exactly does Kaby Lake achieve to improve performance?
The answer is frequency. Previously, a Taiwanese website exposed the model and specifications of the desktop version of the Kaby Lake processor. The flagship Core i7-7700K has a frequency of 4.2GHz and a TDP 95W. This 4.2GHz frequency is actually the base frequency and its acceleration frequency may be as high as 4.5GHz. Currently, The Skylake-based Core i7-6700K is 4.0 to 4.2GHz, in other words the Kaby Lake frequency is 300MHz higher.
However, this is not the first time that Intel has achieved performance improvements by increasing the frequency. It was already used when Haswell Refresh was upgraded. The Core i7-4790K frequency launched that year increased to 4.4GHz, which is 500MHz higher than the highest 3.9GHz of 4770K. Therefore, the CPU performance is improved by about 10%.

If so, then under the same TDP (the earliest TDP of 6700K is 95W, but ARK is now unified to 91W), Kaby Lake processor frequency is higher, and the performance will naturally improve.
As for the nuclear display, the number of EU units may not necessarily increase, but according to this routine, the highest frequency is estimated to increase.
The Intel 14nm process is actually divided into different versions.
It is not simply to increase the clock frequency of the processor to increase the frequency. Behind this is actually an optimized version of the 14nm process. At the IDF conference, Intel announced their process technology roadmap. Although 14nm and 10nm will fight three generations, each generation of technology is actually different, of which 14nm is divided into 14nm and 14 + nm processes, and 10nm is divided into 10nm. , 10 + nm, 10 ++ nm, etc., will not completely use the same process, as usual, there will be different levels of performance and power optimization.
