Our Verdict on Each
An outstanding value CPU that delivers excellent gaming and productivity performance without breaking the bank.
Best for: Building a budget or mid-range gaming PC where value is the top priority.
Read the full reviewA well-balanced 65W quad-core that was a staple in pre-built office PCs, but is too slow for modern demanding workloads.
Best for: For modern users, the Core i5-4430S holds very little value outside of maintaining an older system. If you have a functioning LGA 1150 motherboard and need a cheap processor to keep an office machine or media center running, this chip is adequate. Its quad-core design still handles basic web browsing and document editing reasonably well. However, it struggles significantly with modern gaming and heavy multitasking. It should never be purchased for a new build, as its platform lacks support for modern I/O like NVMe booting (on most older boards), USB 3.1 Gen 2, and DDR4 memory. If you find one used for a few dollars, it might be worth it to revive an old PC. Otherwise, save your money for a modern entry-level processor, which will offer vastly superior single-core speeds and power efficiency.
