How Intel names its processors and why it matters [naming convention and generations]

As time moves, the world’s problems get more complex demanding equally complex solutions. These solutions more often than not rely on computers, which as a result are forced to evolve at a much faster rate to outpace the challenges that be.

Computers, on the other hand, are made possible by processor chips, which are the brains behind them. And when it comes to processor chips, there are few better-known brands than Intel and AMD.

Most computers you will get to interact with a run on an Intel processor. But despite how widespread these processors are, it hasn’t gotten any easier to understand how they are named. Except through the help of benchmarks and reviews, it is almost impossible to tell the difference in performance between processors.

However, to Intel’s defense, they’ve churned out loads of processors in the past… each meant to meet the needs of a unique segment of consumers, and are still churning out more. The vast number of processors and categories of each make finding an easier naming system a daunting task.

Intel processors naming convention

Now, let’s make it a little easier to understand how they go about their naming.

The two main aspects of a CPU naming include its:

  • Processor line
  • Processor Generation (which is determined by its microarchitecture)

Let’s now tackle these two.

1. Processor lines

Most people are to some degree conversant with the Intel Core naming system which includes the Intel Core i3, i5, i7 and i9 series of processors. It’s not so hard to figure out which one performs better than the other as bigger numbers often denote better performance.

However, before the Core naming system came around, there were other lines of processors in existence such as the Pentium/ Celeron and Atom series of processors. These are low-performance processors compared to the Core processors we’ve mentioned above. We’ll leave these for another article.

Note that higher-end Core processors for servers and workstations are sold as Xeon processors

Since Intel churns numerous processors ever so often with each designed to meet the needs of a specific market segment, it was necessary to class these processors in categories otherwise referred to as lines.

You can know the line a processor belongs to by the suffix at the end or middle of its name.

Some of the common suffixes you will likely come across are:


  • X – Very High End, Unlocked – Processors in this category have the most number of cores, offer the best performance and are the most costly. Best for Video Rendering, Gaming, servers, etc. Example: Intel Xeon Core i9-7980XE (XE standing for Extreme Edition).
  • K – Unlocked – Processors in this category have an unlocked multiplier and can be overclocked using traditional methods as long as you have a similarly enabled motherboard. Such is good for gamers and power users.
  • H – High-performance graphics – Processors in this category come with high-end graphics in the mobile segment and consume more power.
  • HK – High-performance graphics, Unlocked
  • HQ – High-performance graphics, Quad-Core – Processors in this category offer high-end graphical performance and have four cores.
  • U – Ultra-Low power – Processors in the category
  • Y – Extremely low power –
  • M – Mobile workstation – You’ll only find this suffix in Xeon Processor for mobile workstations.


  • T = Power- Optimized Life – Processors in the line are designed to consume less power and thus produce less heat. They fit in a standard LGA Desktop socket and are low power processors. They are ideal for small form factor desktops and all-in-ones designed with smaller power supplies or less aggressive cooling.
  • P – Slow/ Poor Integrated graphics – Example: Intel HD 510
  • G – Features Radeon RX Vega Graphics that are built-in

Legacy suffixes used in the 5th Generation Broadwell (5000 Series) include:

  • R  – High-End Mobile – This is a desktop processor with a similar architecture to a mobile processor. Is soldered onto the motherboard. The suffix R is Similar to H in other generations.
  • C – Unlocked processor with high-end graphics (Desktop processor) – Similar to K in more decent generations.

Now that that’s handled, let’s help you feel at home with the basics of Core processors.

Intel Core i3 Vs i5 Vs i7 vs i9

The Core line of processors is made up of mid to high-end processors and was introduced in 2006 as a replacement of the Pentium line up. The Pentium, which was formerly enjoyed a high seat, was now posted as an entry-level line, at the same time pushing the Atom to lower down to an entry-level line of processors.

Examples of the core line include the Enhanced Pentium M (Core Solo and Core Duo) and 64-bit microarchitecture (Core 2 Solo, Core 2 Duo, Core 2 Quad, Core 2 Extreme) before entering the 1st to 9th Generation of processors, each with their own Core i3, i5, and i7 processors.

Our main focus is the Core i3, i5, i7 and i9 series of processors.

Core i3

Core i3 processors offer two cores, come with hyperthreading, have a low Thermal Design Point (Meaning they consume less power and produce less heat) and have onboard graphics. They do not feature hyperthreading They offer enough power for users with light computing needs such as content consumption, word processing, browsing, and some light gaming.

Core i5

Core i5 mobile processors equally come with two cores, while their desktop counterparts come with 4 cores. They offer all the features the Core i3 offer in addition to having a larger cache memory, improved onboard graphics and hyperthreading. A core i3 processor will comfortably meet the needs of any ordinary user with moderate-high demands.

Core i7

The Core i7 processor in the other hand has the largest volume of Cache, better onboard graphics, has two or eight cores (ultrabook and workstation respectively) and supports hyperthreading and virtualization.

Core i9

Core i9, on the other hand, is the latest entrant with the Intel Core i9 8950XE with 6 Cores, 12 threads, and a massive 12Mb of Cache memory.


2. Intel Processor Generations

Every year or year and a half, Intel releases a new generation of processors. Each succeeding generation comes with improvements in either clock speed, power consumption, die area or some slight microarchitecture optimizations.

For instance, the 1st Generation Westmere chips had were manufactured through 32nm processes. The 9th Gen Cannon Lake chips, on the other hand, have a massive die shrink from a 32nm to 10nm. The result you ask? Reduced processor size, more transistors fit into the same CPU which means better performance with far less power consumed.

There are currently 8 Generations of desktop processors and 9 Generations of laptop processors, each with their own series of Core i3, i5, and i9 processors. The 9th Generation of processors, however, has only Core i5 and i7 processors.

These generations are:

  • Westmere microarchitecture (1st Generation)
  • Sandy Bridge (2nd Gen)
  • Ivy Bridge (3rd Gen)
  • Haswell (4th Gen)
  • Broadwell (5th Gen – For mobile processors only)
  • Sky Lake (6th Gen)
  • Kaby Lake (7th Gen)
  • Coffee Lake (8th Gen)
  • Cannon Lake (9th Gen– Currently for mobile processors only).

However, it’s not strange to find a processor or two from a previous generation outperforming ones from a more recent generation. This is especially the case when you compare a top of the line processor from one generation against mid-tier chips in the newer generation. That tells you that while going for a newer generation chip is advisable, it’s worth comparing it with older generation chips to find the chip that offers the best cost to performance ratio.

One way to determine how well a processor performs in by checking for processor benchmarks in sites like PassMark. Let’s have a look at an example of what we had mentioned above regarding generations and performance.

Note how the 3rd Generation Core i7-3930K processor beats the 4th Generation Core i7-4790K (highlighted pink). And below these are a 6th Gen Core i7-6700K and a 7th Gen Core i7-7700 (highlighted blue), both having received a thrashing from their older generation counterparts.

Intel Processors naming convention

Now that we know about Generations and product lines, let’s find what those letters at the end of processor names mean and why it matters.


Take for instance this 8th Generation processor. Then I after the Intel Core alludes to the fact that the processor comes with integrated graphics.

The first digit after the i7 brand modifier represents the generation of the processor, while the three other digits are the processors SKU number (the processor part number). At the end of the processor, the name is an alpha suffix letter represents the processor line.


In this example, however, things are slightly different. The number after the i7 brand modifier shows that it’s a 7th Generation processor. The product line suffix comes next followed by the SKU number.

Just in case you need to compare an Intel processor and an AMD processor, you can do so by visiting CPUBoss.


Intel’s processor naming convention isn’t as friendly to its users as it ought to be ideal. Without a doubt, they need to find an easier and more accommodating method of naming to cater to the majority who don’t particularly care to know but wouldn’t mind knowing if it were a tad easier to do so. But all the same, we as users are not absolved from the necessity of knowing how they do it as long as we buy their products and want to get the best out of our money. If you’ve read this far, congratulations!! Welcome to the camp of the initiated.
