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

If Intel's Tick-Tock strategy has not shut down, so this year we should see 10nm processor technology, but in fact this year, Intel introduced the seventh generation of intelligent processors Kaby Lake or 14nm process, architecture is also not much compared to Skylake Variety. If Kaby Lake just this ability, it is difficult to attract consumers to upgrade, but Intel has already demonstrated earlier honey confidence that although there is no process to upgrade, but they are still able to bring considerable performance improvements.

Combined with the latest news of view, Intel Kaby Lake means to enhance performance may increase the frequency, the flagship Core i7-7700K highest frequency up to 4.5GHz.

Last weekend there Kaby Lake processor CPU tests and nuclear remarkable performance from the results CPU performance does have some improvement, and to enhance the core was even greater. Although this is only the mobile version does not reflect Kaby Lake desktop version, but according to this trend, Intel We still have to spend a little in order to attract consumers to upgrade, otherwise Kaby Lake pointless.

Then, in the process technology, the situation is not much change in the architecture, Kaby Lake in the end is to rely on performance to achieve it?

The answer is by frequency increase. Earlier Taiwan website exposure Kaby Lake desktop processor models and specifications, the flagship Core i7-7700K frequency of 4.2GHz, TDP 95W, 4.2GHz frequency is actually the basis of frequency, the frequency may accelerate up to 4.5GHz, and the present the Skylake architecture Core i7-6700K is 4.0 to 4.2GHz, in other words Kaby Lake high frequency 300MHz.

But this is not the first time Intel achieve performance gains by increasing the frequency, when the original Haswell Refresh upgrade has used this trick, and then launched Core i7-4790K frequency is raised to 4.4GHz, 500MHz higher than the maximum of 3.9GHz 4770K, Therefore, CPU performance increase of about 10%.

If so, then at the same TDP (6700K earliest TDP is 95W, but the ARK is now unified to 91W), Kaby Lake higher processor performance will naturally increase.

As for nuclear was, EU does not necessarily enhance the number of units, but according to this routine, the highest frequency estimation will be improved.

Intel 14nm process is actually divided into different versions

Upgrade the processor frequency is not a simple clock frequency can be improved, and in fact behind this is an optimized version of the 14nm process. Meeting at IDF, Intel announced their process technology roadmap, although the 14nm, 10nm have three generations of war, but in fact, every generation processes are different, which is divided into 14nm to 14nm and 14 + nm process, is divided into 10nm 10nm , 10 + nm, 10 ++ nm, etc., are not entirely the same process, as usual, there will be varying degrees of performance, power optimization.
