AMD Ryzen 5 3400G APU 2nd Generation Processor ( 4.2 GHz / 4 Cores / 8 Threads )

The AMD Ryzen 5 3400G is a second-generation Ryzen G-series APU built on AMD's 12nm FinFET process node. It targets AM4 socket motherboards and combines a capable quad-core CPU with integrated Radeon RX Vega 11 graphics in a single package, making it a solid foundation for compact desktops, home-office builds, and entry-level gaming systems that do not require a discrete graphics card. On the CPU side, the processor runs at a base clock of 3.7 GHz and can boost up to 4.2 GHz via AMD's Precision Boost 2 technology, which steps clock speeds in 25 MHz increments based on real-time thermal and power headroom. The four cores support simultaneous multithreading, yielding eight logical threads for improved multitasking responsiveness. The cache hierarchy consists of 384 KB of L1 cache, 2 MB of L2 cache, and 4 MB of shared L3 cache, which AMD markets under the GameCache branding to reduce memory-access latency. The integrated Radeon RX Vega 11 graphics engine features 11 compute units running at up to 1400 MHz, with display output over both DisplayPort and HDMI supported at the motherboard level. Memory support covers dual-channel DDR4 at up to 2933 MHz, which directly feeds GPU performance since the iGPU shares system memory. The processor ships with an AMD Wraith Spire cooler and carries a 65 W default TDP, with a configurable TDP range of 45–65 W for power-constrained builds. A maximum junction temperature of 95 °C is specified. The chip is fully unlocked, and AMD Precision Boost Overdrive allows one-click overclocking when paired with a compatible motherboard. AMD Ryzen Master software provides up to four user-defined performance profiles and real-time per-core monitoring. AMD StoreMI technology is also supported, enabling tiered SSD and HDD storage acceleration. PCIe connectivity is provided via a PCIe 3.0 x8 interface.
