Generations of Intel processors means:

The generations are one of the most challenging sections of Intel processor naming. the joyous news After seeing it explained, it’s simple to understand. Technology enthusiasts frequently discuss the many “Lake” CPU families, including Whiskey, Ice, and Sky, as well as the 9th, 10th, and 11th generation processors. However, “lakes,” “generations,” and “microarchitectures” are all synonyms for one another.
Every generation offers notable performance improvements that boost productivity and connectivity. These improvements include longer battery life, faster clock speeds at up to 5.3 GHz with Turbo Boost, Intel WiFi 6 (Gig+), ThunderboltTM 3 technology, and immersive 4K HDR.

For desktops:

K is unlocked CPU (For example Core i7–9700K)

X is the Extreme series of CPU (For example Core i9–9960X)

XE is the highest core count variant of X CPU (For example Core i9–10980XE)

R (Broadwell only) is a CPU that fits in BGA sockets

C (Broadwell only) is the K series but for Broadwell

T is low power desktop CPU (For example Core i3–9300T)

F is CPU without integrated graphics (For example Core i5–9400F)

For laptops:

U is low power laptop CPU (For example Core i3–10110U)

Y is ultra-low power CPU (For example Core i7–10510Y)

H is high power CPU (For example Core i7–9750H)

G (Gen 8) is CPU with AMD Radeon Vega iGPU (For example Core i7–8809G)

G (Gen 10) is CPU with Iris Pro iGPU (For example Core i5–1065G7)

HQ (before Gen 8) is an H CPU with 4 cores (For example Core i7–7920HQ)

The central family of Intel CPUs is called the Core. When they were first introduced in 2006, they took the place of the well-liked Pentium line as the norm for high-end CPU chips. They release a new generation every one to two years and provide a variety of models including Core i3, i5, i7, i9, and X.
As a general rule, the better the chip is 1) the higher the Core I number; and 2) the newer the generation. Therefore, an Intel Core I7 CPU will perform better than an Intel Core i5 processor, and an Intel Core i9 chip from the 11th generation performs better (and has more features) than a Core i9 chip from the 10th generation.

Indicator of Generation
The first or first and second digits of the 4 or 5-digit processor number will indicate the processor generation.

The numerals would begin with 8XXX or 9XXX if the CPU belonged to a generation that only had one integer (for example, the 8th or 9th generation). The numbers would be line 10XXX or 11XXX, respectively, whether it belonged to the 10th or 11th generation.

The generation denotes the number of characteristics of the processor, including its release date, the size of the transistors it uses, the type and size of its cache, etc.
