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

Some people might not really know what Intel Core i7 Processor’s names mean entirely. Especially the part about the suffixes or letters that are found at the end of the Processor name. A lot of people don’t really know what these suffixes mean and each generation has some sort of “iteration” of the same processor with a Suffix added to it, but what does it mean?

What are the most Common Intel Core i7 Processor Suffixes?

Suffixes are basically the way of Intel of telling us what the Processor itself is meant to do and what kind of system is supposed to be run with. The suffixes are often seen at the end of the model name but some suffixes are actually located on the middle of the name itself. To understand what each suffix mean, we need to look at the common ones.

The Most Common Intel Core i7 Processor Suffixes

The processor-number is one of several factors, along with processor brand, specific system configurations, and system-level benchmarks to be considered when choosing the right processor for your computing needs. As discussed before, the number that shows first stands for the Generation of the Intel Core processor while the rest denominates the sort of features it has.

A higher number within a processor class or family generally indicates more features, but it may be more of one and less of another. Once you decide on a specific processor brand and type, compare processor numbers to verify the processor includes the features you are looking for.

What are the Meanings of Each Letter?

We’ll break down the meanings of each suffix letter as quickly as possible so you don’t have to worry about not knowing what each processor is supposed to mean. Surely, “Unlocked” is supposed to mean it has easy access to your computer, right?

  • “K” – This suffix means that a chip’s multiplier is Unlocked which means that it can easily be overclocked. This feature’s functionality heavily depends on the motherboard.
  • H” – This suffix actually is self-explanatory. This is used mostly to benefit Mobile Intel Processors. In other words, this is mostly for laptops. More often than not high-end Gaming Laptops can also come with a “Q” attached to it, which simply means it’s a Quad-Core Processor.
  • “U” and “Y” – Both of these suffixes are related to the power consumption of the chip itself. This is basically the way of Intel to tell you that the processor is meant to save battery life rather than focusing on performance.
  • “T” – This suffix makes clear that the processor is meant for Desktop computers but it also has low-power consumption options as well. Often seen in Small Form Factor (SFF) computers.
  • “P” – This Suffix signals the fact that the Intel Core Processor doesn’t have a powerful integrated Graphics Card chip. They are cheaper and can actually help with the costs of graphics card
  • “X” – This is the suffix that determines that the chip is actually of the “Extreme” variety of chips. It’s a high-end CPU with Unlocked Capabilities. It’s the best of the best sold at extremely high prices but they are there to signal that it’s the best of the branch. This is often seen in Intel Core i9 Processors more than anything else.
  • “E” – This means that the computer is compatible with Error-Correcting Code Memory chips. This is basically the type of memory that can actually fix data corruption and is essential in business computers.

Intel’s way of naming processor functions through suffixes is odd. However, once the user learns what these letters stand for, they can have an easier time knowing what the function of the processor is and why it either benefits or works against them.
