What do the Letters (Suffixes) on Intel Core i7 Processors Mean?

Intel Core i7 processors are some of the most popular and powerful processors on the market, but what do the letters at the end of their names mean? These letters are known as suffixes and they represent different versions of the processor. In this article, we will explore the different suffixes found on Intel Core i7 processors and what they signify.

K – Unlocked Processor

The “K” suffix on an Intel Core i7 processor means it is an unlocked processor. This allows the user to overclock the processor, meaning they can push it to run at higher speeds than its base clock frequency. Overclocking can provide a significant performance boost, but it also puts more strain on the processor and can generate more heat. There are also some features that are only available on unlocked processors, such as Intel Turbo Boost Technology and Intel Optane Memory support.

H – High-Performance Graphics

The “H” suffix on an Intel Core i7 processor indicates that it has a higher-performance graphics unit built into the processor. These processors are known as “Intel Core i7 with Intel Iris Pro Graphics” or “Intel Core i7 with Intel HD Graphics”. The higher-performance graphics can handle more demanding graphics tasks, such as gaming and video editing. However, these processors may also run hotter and consume more power compared to other versions.

U – Ultra-Low Power

The “U” suffix on an Intel Core i7 processor represents ultra-low power consumption. These processors are designed for use in laptops and other mobile devices where battery life is crucial. They have a lower base clock speed and power consumption than other versions, but this also means they are not as powerful. However, these processors are still capable of handling most everyday tasks and are ideal for those who value battery life over performance.

Y – Extremely Low Power

The “Y” suffix on an Intel Core i7 processor indicates that it is extremely low power and designed for ultra-portable devices such as tablets and 2-in-1 laptops. These processors consume even less power than the “U” versions and have a lower base clock speed. This makes them suitable for basic tasks such as web browsing and document editing, but they may struggle with more demanding tasks.

HK and HQ – Higher Performance Laptop Chips

The “HK” and “HQ” suffixes on an Intel Core i7 processor indicate that it is a higher-performance laptop chip. These processors have a higher base clock speed and more cores compared to other versions. They are ideal for gaming laptops and high-performance laptops where raw processing power is important. However, these processors also consume more power and may generate more heat, so they are mainly found in larger and thicker laptops with better cooling systems.


In summary, the letters on Intel Core i7 processors indicate different versions of the processor with varying levels of performance, power consumption, and other features. The “K” suffix represents an unlocked processor that can be overclocked, the “H” suffix indicates high-performance graphics, and the “U” and “Y” suffixes represent ultra-low and extremely low power versions, respectively. The “HK” and “HQ” suffixes are found on higher-performance laptop chips, and they offer a balance of power and efficiency. Knowing the differences between these suffixes can help you choose the right Intel Core i7 processor for your needs.
