What is the difference between cpu with k and without k

The difference between cpu with k and without k: 1. The processor with K suffix can be overclocked, but the processor without K cannot be overclocked. The processor with K has no locked multiplier, and the multiplier without K is not locked. It is locked; 2. The motherboards for models with K and without K are also different.

The difference between cpu with k and without k:

1 , Processors with a suffix of K can be overclocked, while processors without a K cannot be overclocked. For processors with K, the multiplier is not locked. If the motherboard is configured with a subtitle starting with Z, the multiplier can be modified directly. The overclocking success rate is high and can improve certain performance; for processors without K, the multiplier is locked and can only be modified if it is overclocked. FSB, but the room for performance improvement is very limited.

2. The motherboards used with models with K and without K are also different. For example, for i7-7700 processor, the best cost-effective combination is B250 mainstream motherboard, while for i7-7700K processor, you need Pairing it with a high-spec Z270 motherboard that supports overclocking is the first choice.

3. For example: Core i7-7700 and Core i7-7700K, the only difference in naming is the "K" suffix. Of course, i7-7700K has the feature of overclocking, and the default frequency What's more, starting from 4.2GHz, the Turbo frequency can also accelerate to 4.4GHz. The i7-7700 has removed the overclocking feature. The default main frequency is only 3.6GHz, and it can reach 4.2GHz through turbo frequency (the default frequency level of the i7-7700K). Obviously, the i7-7700K of the K series is more suitable for users who pursue high performance than the i7-7700. Even if it is overclocked, it can obtain a main frequency performance of 0.6GHz, which translates into 8-10% actual performance in actual applications and games. Advantage.
