Buying Guide: How to Choose the Best CPUs Under $100 in 2025
When you are building or upgrading a PC on a tight budget, every dollar counts. The sub-$100 CPU market is a competitive space, and knowing what to look for can mean the difference between a sluggish machine and a surprisingly capable one. I have put together this guide to help you navigate the key factors for picking the right processor without breaking the bank.
First, you need to think about cores and threads. A few years ago, quad-core was the standard here, but now you will often find hexa-core (6-core) CPUs in this price bracket. More cores are generally better for multitasking and modern games that are designed to use them. Threads, handled by technologies like Intel’s Hyper-Threading or AMD’s Simultaneous Multithreading (SMT), allow each core to handle multiple tasks. A 6-core, 12-thread CPU will often feel much snappier than a 4-core, 4-thread one when you have multiple applications open.
Next is the platform, which means the socket and chipset. Are you buying a new motherboard, or are you trying to drop a new CPU into an existing one? If you are upgrading an older system, your choices are limited to what your current motherboard supports. For a new build, you will be choosing between AMD’s AM4 or AM5 platforms and Intel’s LGA 1700 or its successor. AM4 is a mature platform with a huge selection of affordable motherboards, while AM5 is newer but requires DDR5 memory, which can increase the total cost. I always check motherboard compatibility and pricing before settling on a CPU.
Integrated graphics is a huge deal in this budget category. If you are not buying a separate graphics card, the CPU’s integrated GPU is what will display everything on your screen. AMD’s Vega and Radeon Graphics, along with Intel’s UHD and Iris Xe graphics, have come a long way. They can handle desktop tasks, video streaming, and even some light gaming. If you plan on any serious gaming, a dedicated GPU is still a must, but a good iGPU can save you a lot of money upfront.
Finally, consider the thermal design power (TDP). This gives you a rough idea of the heat output and power consumption. A lower TDP (like 65W) often means a cooler and quieter system, as it can be handled by a simple stock cooler that comes in the box. Higher TDP chips might require a more robust aftermarket cooler, adding to your total cost. For the 9 best CPUs under $100 in 2025, I have prioritized options that offer a great balance of performance, platform value, and included cooling solutions to keep your build simple and affordable.
Frequently Asked Questions
Can I really game on a CPU under $100?
Yes, but with some important caveats. You will not be pushing high frame rates at 4K resolution in the latest AAA titles, but these CPUs are perfectly capable for 1080p gaming, especially when paired with a decent budget graphics card like an NVIDIA GTX 1660 or an AMD RX 6600. The experience is much more dependent on your GPU at this level. For esports titles like Valorant, League of Legends, or CS:GO, a modern sub-$100 CPU with strong single-core performance will do an excellent job.
Is it better to buy a new budget CPU or a used older high-end one?
This is a classic debate. A new budget CPU, like one from our list of the 9 best CPUs under $100 in 2025, comes with a warranty, a brand-new stock cooler, and support for modern features like PCIe 4.0 and faster memory. A used older flagship might have more cores but often lacks these newer technologies and can be less power-efficient. For a beginner, I almost always recommend going with a new CPU for the peace of mind and modern platform support.
Do these CPUs come with a cooler?
Most, but not all, CPUs in this price range include a capable stock cooler in the box. AMD is particularly known for including decent coolers even with their budget offerings. However, it is always a good idea to double-check the product listing before you buy. Some higher-TDP models or special editions might not include one, so you will need to factor the cost of an aftermarket cooler into your budget.
What is the biggest limitation of a sub-$100 CPU?
The primary limitation is future-proofing. These processors are fantastic for their price, but they represent the entry-level of performance. You might find that in a couple of years, demanding new software or games will start to push them to their limits. They also often have fewer PCIe lanes, which can limit expansion options, and may not support the absolute fastest memory speeds. They are a fantastic value for a current budget build but are not designed for heavy, long-term workloads like video editing or 3D rendering.
How important is RAM speed with these processors?
RAM speed is very important, especially for CPUs with integrated graphics. The iGPU uses your system’s RAM as its video memory, so faster RAM directly translates to better gaming performance on the integrated graphics. For systems with a dedicated graphics card, the effect is smaller but still noticeable. I would aim for at least 3200MHz for an AMD AM4 system and 3600MHz if your budget allows. Always check your CPU and motherboard’s official memory support list for the best results.
