What is the difference between Intel processors X and K, such as i7980X and i73770K?

Differences between Intel processors X and K:

1, with different performance.

X suffix stands for the most powerful CPU of its generation. K suffix = unlocked frequency doubling and higher performance.

Since Intel restricted overclocking in SandyBridge era, K suffix has become the symbol of overclocking. XE suffix-supreme flagship.

2, the degree of fever is different.

K calorific value is very low, X performance is very strong, and calorific value is high. Usually, the power consumption of surfing the Internet and listening to music is about 36W, and it exceeds 95W when fully loaded. The original fan is reserved at 35, and the full load does not exceed 50. Up to now, X has not been used 100%. It takes 8 to hit 100% with SP2004.

3. Different processor technologies.

Intel? Core TMI 9-7980 XE Extreme Edition processor, 18 with 36 threads, TDP165.0W, 2.60GHz? 4.20GHz is the core model in the history of Intel fever platform.

Extended data

The difference between Intel processor models with and without K.

In fact, the difference between K series and non-K series is that the default frequency of the same model K series will be greatly improved than that of non-K series, except for the difference of unlocking frequency multiplication.

In other words, the K series has two bright spots, one is super, and the frequency has been optimized for you when it leaves the factory. In addition, there are different motherboards with and without K models.

For example, for the i7-7700 processor, the best cost performance can be matched with the B250 mainstream motherboard, while for the i7-7700K processor, it needs to be matched with the high-specification Z270 motherboard to support overclocking.

For example, the only difference between Core i7-7700 and Core i7-7700K is the addition of a "k" suffix. Although i7-7700K has the feature of overclocking, the default frequency is from 4.2GHz.

Turbo frequency can also be accelerated to 4.4GHz. i7-7700 removes the overclocking function, and the default main frequency is only 3.6GHz, and it can only reach 4.2 GHz (the level of i7-7700k mute frequency) through turbo frequency.
