Product Line Suffix: The SKU suffix is another key indicator of processor capabilities. Other differences are indicated by letter-based product line suffixes. For example, on Intel® Core In the processor family, U indicates a processor designed for power-efficient laptops or 2-in-1s. XE, on the other hand, refers to the “Extreme Edition” processor for desktops designed for maximum performance.

Form/Function Type/Market Segment	suffix	optimization/design
Desktop	K	High performance, unlocked frequency
	Φ	Requires a discrete graphics card
	S	special edition
	T	Power Optimized Lifestyle
	X/XE	Maximum performance, unlocked
Mobile Devices (Laptops 2, 2-in-1s)	HX	Highest performance, all SKUs unlocked
	HK	High performance, unlocked frequency
	h	high performance
	P	Provides the performance required for thin and light devices
	u	more energy efficient
	Y	Very low power consumption
	G1-G7	Graphics class (processors with newer integrated graphics technology)
Embedded	E.	Embedded
	UE	more energy efficient
	HE	high performance
	UL	Power Efficient in LGA Package
	HL	High performance in an LGA package

Note: Φ, read as Phi

Processor Naming Format

Take the 13th generation i7 processor I am using as an example, the Chinese name is Intel® Core i7-13700KF processor (English name Intel® Core i7-13700KF Processor)

Among them, Core is the brand name, and there are other brand names such as Pentium, Celeron, and Xeon. (According to the official website: Intel® Pentium® and Intel® Celeron® product lines will switch to “Intel® Processors” from 2023)

Among them, i7 is a brand modifier (i series naming is only used for Core), generally there are i9, i7, i5, i3, and the larger the number in the same generation, the stronger the general performance

Among them, 13 is a generation indicator, such as 13th generation and 12th generation. In the same series, the higher the generation number, the stronger it is. However, it should be noted that the new generation i5 can compete with the old generation i7 (the price is generally the same), By default, upgrade once, the next file, and so on. Usually 3 digits, but there are also 2 digits.

Among them, 700 are SKUs, and SKUs are usually allocated in the order of processor development in this generation and product line. Assuming the rest of the processor brand and generation are identical, a higher SKU generally means more features. However, SKU numbers are often not the best indicator for comparing different generations or product lines. Such as 900, 700, 500, 400, 300, and the relatively rare special product 490.

The English at the end is a suffix.

suffix

The most common ones on the Desktop side are no suffix, K, F, and KF

Among them, whether there is K/X means whether it can be overclocked, and those without K/X generally cannot be overclocked (X is higher than K). (It should be noted that CPU and memory overclocking also requires motherboard support)

Whether there is an F generally means whether there is a built-in core graphics card, and it is sometimes called “core display, integrated display” (it should be noted that the core display in the desktop can be used together, not only one, there is F Generally refers to no verification display, so the one with F is generally one or two hundred yuan cheaper than the one without F)\

The most common ones on the Laptop/Mobile end are U, H, and HX

Among them, U stands for high energy efficiency. In fact, it is often low voltage, low power consumption, and low heat generation. It is often used in office notebook computers and ITX mini hosts.

Among them, H stands for high performance, which is often used in mid-range gaming laptops (generally 5-10K).

Among them, HX stands for high performance + overclocking, which is often used in high-end gaming laptops (generally 15-30K).

In addition, due to the limitation of power consumption and power supply of notebooks, neither notebooks nor graphics cards can beat desktops of similar models.

Other suffixes are rare, professional, and generally not used.
