Where To Buy Laptop Processors NEW!

Mobile processors are the brain of your notebook, 2-in-1 laptop or mini PC. They combine advanced functionalities with energy efficiency to prolong your device's battery life. Choosing the right processor can make a big difference, allowing you to enjoy faster performance, superior reliability and built-in security features.

Unlike desktop processors, mobile processors power portable devices such as laptops, tablets or smartphones. They tend to generate less heat inside the computer case. Most mobile CPUs also consume little power, so your laptop or tablet will have a longer battery life. Mobile CPUs work well even with fanless cooling systems.

Multi-core processors offer extra performance. Each core is a processing unit on the processor chip; for example, a single-core processor has one processing unit. The operating system sees the cores as separate CPUs, so each one of them can perform a different task. A dual-core processor can perform two tasks at the same time, a quad-core processor can perform four tasks at the same time, and so on. Since all the cores are on a single chip, a multi-core configuration doesn't affect the size of the mobile processor. This is particularly useful in smaller computer cases, where saving space is of paramount importance. The cores can communicate with each other fast to reduce latency, not a feature of server processors. Two types of multi-core mobile CPUs are dual-core and quad-core.

Your laptop's CPU is essentially the brain of the device. This is the part that will load the operating system, start any programs, run those programs, retrieve data for you, and monitor your computer's performance. The processor is at the core of your laptop's functionality, and you can explore eBay to find a model with the features and specifications that work for you.

The clock speed of your laptop CPU is measured in megahertz or gigahertz in most cases. This speed refers to the number of pulses per second that an oscillator will generate to set the processor's tempo for smooth operation. You can think of clock speed as one of the many ways to measure the power of your laptop computer. It helps to determine how fast your machine can process data, but there are other factors at play here as well. You can use eBay to find a processor that has the minimum clock speed you require. Some measurements you will find are:

Many laptop processors house several cores within a single shell or design. In a multi-core system, each core runs tasks from the laptop's CPU independently. A single core can process data from several tasks at once. Although several factors contribute to the speed and efficiency of a processor and its cores, a multi-core laptop processor has the ability to run many programs and retrieve data at a quick pace. It can also help you with CPU clock speeds. You can go to eBay to find processors with core counts such as:

eBay hosts several brands that manufacture and sell laptop CPUs. If you have a particular brand of computer and would like to ensure compatibility, you can choose a CPU for the laptop of your choice using the menu options on the side of the eBay page. Note that some processors may work in laptops that are not made by the same brands. Some common brands you will find on eBay include:

Computers are my lifelong obsession. I wrote my first laptop review in 2005 for, continued with a consistent PC-reviewing gig at Computer Shopper in 2014, and moved to PCMag in 2018. Here, I test and review the latest high-performance laptops and desktops, and sometimes a key core PC component or two. I also review enterprise computing solutions for StorageReview.

Just as it is with desktops, at the heart of every laptop computer is a central processing unit (CPU), commonly called a processor or a chip, that's responsible for nearly everything that goes on inside. The CPUs you'll find in current laptops are made by AMD, Intel, Apple, and Qualcomm. The options may seem endless and their names byzantine. But choosing one is easier than you think, once you know a few CPU ground rules.

Broadly speaking, today's laptop processors use either the ARM or x86 architecture. The latter was created by Intel in 1978 and dominates the PC industry, with Intel and AMD battling for market-share supremacy. ARM-based chips, on the other hand, are produced by hundreds of different companies under license from the British firm ARM Limited, owned by Softbank. (For a while, it looked like Nvidia was on the path to acquiring ARM from Softbank, but the chip maker has abandoned its efforts.)

Found in billions of devices from smartphones to supercomputers, ARM chips had been seen only in some Chromebooks and a very few Windows laptops (based on Qualcomm CPUs) until Apple switched from Intel to its own ARM-design M1 processors in late 2020, and now its M2 chips in 2023. Apple's changeover is a leading reason that ARM chips are seeing wider acceptance as an alternative to x86 for mainstream computing. (See our Apple M2 chip explainer.)

Your architecture choice is preordained if you're an Apple user since all its laptops now use an M1 or M2 chip variant. But Microsoft Windows, ChromeOS, and many Linux operating systems are compatible with both ARM and x86. Based on our reviews of today's handful of Qualcomm-powered Windows systems like the Microsoft Surface Pro X tablet and the Lenovo ThinkPad X13s Gen 1, x86 remains our recommended architecture for Windows until more apps are written to run natively on ARM.

Apps written for x86 can operate on ARM chips through software emulation, but the translation layer slows performance compared to code written to run on ARM in the first place. Similarly, the occasional ARM CPUs (notably from MediaTek) seen in budget Chromebooks have proven much less peppy than the Intel and AMD processors in midrange and premium Chromebooks.

Today's laptop CPUs are composed, in part, of two or more physical cores. A core is essentially a logical brain. All else being equal, more cores are better than fewer, although there's a ceiling to how many you can take advantage of in any given situation. A much-simplified analogy is the number of cylinders in a car engine.

In olden days, CPU cores could process only one thread at a time, but today's processors frequently (but not always) have thread-doubling technology that allows one core to work on two threads simultaneously. An eight-core chip with this technology, for example, can handle 16 threads at a time. Intel calls this Hyper-Threading; the generic term is simultaneous multithreading (SMT).

At the minimum, look for a processor that can process four threads. Users working on heavy media creation and conversion tasks will want the ability to handle eight or more. Core count trumps thread count; all else being equal, an eight-core CPU without multithreading will generally outperform a quad-core processor with it. Of course, in the world of processors, all else is seldom equal; that's why so many varieties of chips exist. (We'll get into the new kinds of cores that Intel has introduced in the last year or so a little further down; they make different chip makers' cores even harder to compare than ever.) The next item, clock speed, is another key differentiator.

To complicate things further, today's processors typically have two advertised clock speeds: a base (minimum) clock and a boost (maximum) clock, sometimes dubbed turbo speed since Intel refers to the duality as Turbo Boost technology. When handling light workloads, the CPU runs at its base clock, typically between 1GHz and 2GHz for laptop chips though sometimes higher depending on the processor's rated wattage. (More on that variable in a minute.) With the latest CPUs from Intel, you may have ratings for multiple possible peak boost clocks, depending on how many cores in the CPU are boosting at a time.

Some low-end laptop processors lack a boost clock altogether, limiting their performance under pressure. Laptop CPUs' boost clocks are often as high as their desktop counterparts, but are usually not sustained for as long before ramping down due to power or thermal limitations. This concept is called "throttling," a safety measure built into the processor to keep it running within its rated specifications. 041b061a72
