What is the difference between cpu with k and without k

Editor to share with you what is the difference between cpu with k and without k, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

The difference between cpu with k and without k: 1, the suffix with K can overclock, the processor without K cannot overclock, the processor with K does not lock the frequency multiplier, and the frequency doubling without K is locked; 2, the motherboard with and without K is also different.

The difference between cpu with k and without k:

1. Processors with suffix K can overclock, and processors without K can not overclock. The processor with K does not lock the frequency doubling, and is equipped with the Z sub-beginning motherboard, which can directly modify the frequency doubling, which has a high success rate of overclocking and can improve a certain performance; without K, the frequency doubling is locked, and if overclocking can only modify the external frequency, but the performance improvement space is very limited.

2. The motherboards with and without K models are also different, such as the i7-7700 processor, the best performance-to-price ratio is the B250 mainstream motherboard, while the i7-7700K processor needs to be equipped with a high-specification Z270 motherboard that supports overclocking.

3, for example: core i7-7700 and Core i7-7700K, the only difference in naming is a "K" suffix. Although i7-7700K has the feature of overclocking, the default frequency starts from 4.2GHz, and Rui Frequency can also accelerate to 4.4GHz. While i7-7700 removes the overclocking feature, the default dominant frequency is only 3.6GHz, which can reach 4.2GHz through Rui frequency (i7-7700K silent frequency level). Obviously, the i7-7700K of the K series is more suitable for those users who pursue high performance than the i7-7700. Even if he overclocks, he can get the main frequency performance of 0.6GHz, which has 8-10% actual performance advantage in practical applications and games.
