Should you buy 9th- and 10th-generation Intel processors and AMD Ryzen 3000 processors in 2026?

Yes, but they’re better suited for a budget upgrade or a used build. If you’re building a computer from scratch, the older 9th- and 10th-generation Intel processors and Ryzen 3000 series are already outperformed by newer models in terms of value. That’s why we recommend comparing processors in the CompX catalog and deciding which option is right for you. The configurator on the website will help you choose the right motherboard and memory to go with your processor. 

Which Older Processors Are Still Worth Buying

In 2026, you can still find several older processors at computer stores that are well-suited for a budget build or upgrading a pre-built PC:

• Ryzen 5 3600 — 6 cores; 12 threads. A decent option for an affordable gaming build, provided you can find a used one that’s significantly cheaper than the Ryzen 5 5500. By the way, AMD still maintains an active support page for this model.
• Ryzen 7 3700X — 8 cores; 16 threads. Go for this if you have an older AM4 system and, in addition to gaming, work with video editing or other multithreaded applications.
• Core i9-9900K — 8/16. It makes sense as a final upgrade for an existing LGA1151 PC. There’s no need to build a new system around it in 2026.
• Core i7-10700 / 10700K — also 8/16. A good upgrade for LGA1200 owners who want to keep their existing motherboard and DDR4 memory.

When an older platform is actually a good deal

For an online computer store or the secondhand market, use this simple rule: calculate the total cost of the entire system right away. The CPU + motherboard + RAM should cost approximately 60% of the price of a modern platform with a similar purpose. In that case, the savings justify using older hardware.

If you want to buy computer hardware to upgrade a pre-built PC, the situation is even simpler. If you already have a B450 motherboard and a Ryzen 5 2600, you can install a Ryzen 5 3600, 3700X, or even a Ryzen 5000 series processor right away after verifying compatibility with your specific motherboard. For example, the Ryzen 7 5700X3D is officially compatible with B450, B550, X470, and X570, so AM4 offers a solid path for future upgrades.

Intel or Ryzen 3000: Which to Choose

At computer stores, older 9th–10th Gen Intel processors are worth considering primarily for pre-built systems. If you have an LGA1151 socket, look for a good deal on the i9-9900K. If you have an LGA1200 socket with a weaker Core i3 or i5, consider the i7-10700.

For building a used PC from scratch, AM4 is a more interesting option. Motherboards on this platform support a wide range of Ryzen processors, and in 2026, AMD even released a new anniversary edition of the Ryzen 7 5800X3D for AM4.

So ,when you goto a computer store, keep this in mind: an older Intel processor is best for a budget upgrade to an existing PC; a Ryzen 3000 is ideal for an affordable AM4 build with the option to upgrade to a Ryzen 5000 later. If you’re building a new system from scratch, go with a more modern platform.
