Its AM4 socket and support for B350, X370, and A320 chipsets offer upgrade flexibility, while the bundled cooler keeps setup simple. Best for budget desktop users who need integrated graphics for light gaming and everyday tasks without a dedicated GPU.
AMD FX FD8300WMHKBOX 8-core AM3+
Why we recommend this ▼
Built on a 32nm Vishera architecture with a 95W TDP, this unlocked 8-core processor offers a 4.2GHz boost clock and a substantial 8MB L3 cache for multitasking on the AM3+ platform. Its boxed cooler and native 8-core design provide a straightforward, tuneable solution for handling multiple intensive applications simultaneously. This chip is best for budget-conscious builders maintaining legacy systems who need basic megatasking capabilities, not modern gaming or AI workloads.
AMD A-Series A6-9500 2-core AM4
Why we recommend this ▼
Built on a legacy 28nm process, this dual-core processor fits the AM4 socket and includes a Radeon R5 integrated GPU for basic display output. Its 65W TDP and included boxed cooler make it a simple drop-in solution for older AM4 motherboards that support DDR4 memory. This chip is best for users needing a minimal-cost processor to perform a BIOS update or power a basic office PC for web browsing and document editing.

Why we recommend this ▼
The A10-7850K pairs four 4.0GHz CPU cores with Radeon R7 integrated graphics on the FM2+ socket, delivering 856 GFlops through its H.S.A. architecture. Its unlocked multiplier and Mantle API support enable console-like optimizations for budget builds without a discrete GPU. This APU suits entry-level desktop users who need light gaming and basic productivity from a single, low-cost component.
AMD Ryzen Threadripper 1920X 12-core sTR4
Why we recommend this ▼
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.
