Best CPUs Under €300 in 2026

The 5.1GHz boost clock on this 5nm mobile chip delivers strong single-thread performance for everyday tasks, backed by 32MB L3 cache and Radeon Graphics. Its 65W TDP and unlocked multiplier make it a flexible option for budget builds, though the LGA 2066 socket limits motherboard choices. Best for hobbyists upgrading older systems who prioritize efficiency and productivity over server workloads.

The 7nm Zen 3 architecture delivers strong efficiency with a 65W TDP and a 4.5GHz boost clock, making it a cool-running option for existing AM4 systems. Its 32MB of L3 cache and bundled Wraith Stealth cooler provide solid out-of-the-box value for a drop-in upgrade. This processor is best for budget-conscious PC builders seeking a capable 6-core, 12-thread chip for productivity workloads without needing a discrete GPU.

Eight physical cores with a 4.9GHz boost clock deliver strong single-thread performance for gaming, bypassing the hyperthreading overhead of its i9 sibling. The unlocked 95W TDP on the LGA 1151 socket provides straightforward overclocking headroom for users with existing 300-series motherboards. This processor is best for pure gamers seeking high frame rates who don't need the extra threads for streaming or video rendering.

The 3.16 GHz dual-core clock speed and 6 MB L2 cache make this LGA 775 processor a dependable upgrade for older motherboards, with a 65 W TDP that keeps thermals manageable. Its 1333 MHz front-side bus and Intel Virtualization Technology support add practical value for legacy systems, while the 4.5-star rating from 221 buyers reflects consistent reliability. Best for budget-conscious users maintaining or reviving a pre-2010 desktop for everyday tasks like web browsing, office work, or light media playback.

The 12-core, 24-thread design with 64 PCIe 3.0 lanes delivers strong parallel throughput for multi-threaded workloads, backed by a 4.0GHz boost clock. Its unlocked multiplier and quad-channel DDR4 ECC support offer accessible overclocking and memory flexibility on the sTR4 platform. This processor suits budget-conscious workstation users running virtual machines or heavy batch rendering who need high core counts more than single-thread speed.

The 7nm Zen 2 architecture and unlocked multiplier on this 4-core, 8-thread chip deliver strong budget overclocking potential with a 3.9GHz boost and 16MB of L3 cache. Its 65W TDP and included Wraith Stealth cooler keep platform costs low on the mature AM4 socket with PCIe 4.0 support. This processor is best for entry-level PC builders who want a responsive, overclockable foundation for light gaming and everyday productivity.
