AMD Ryzen 7 3800X 100-100000025BOX desktop processor

8-core AM4 desktop processor

The AMD Ryzen 7 3800X is an 8-core, 16-thread unlocked desktop processor built for the AM4 platform. It targets enthusiasts and content creators who need strong multi-threaded throughput for rendering, compilation and heavy multitasking workloads. The chip operates at a 3.9 GHz base clock with a maximum boost of 4.5 GHz, supported by 32 MB of L3 cache and 4 MB of L2 cache. DDR4 memory runs across two channels and the processor exposes 16 lanes of PCI Express 4.0 and 3.0 connectivity.

Sustained-load behaviour at 105 W TDP

With a thermal design power of 105 W the processor is rated for continuous operation at its base frequency when paired with adequate cooling. The 7 nm Matisse die and 32 MB L3 cache help maintain throughput during long rendering or encoding sessions without relying on short burst behaviour. Boost clocks up to 4.5 GHz are opportunistic and depend on thermal headroom and motherboard power delivery rather than a fixed all-core guarantee. The dual-channel DDR4 controller keeps memory bandwidth stable under prolonged multi-threaded pressure.

Installation notes for Socket AM4

The processor drops into any Socket AM4 motherboard that carries a BIOS version supporting 3rd Gen Ryzen; older boards often need a firmware update before the CPU will post. No specialised tools are required beyond standard thermal paste and a compatible cooler rated for at least 105 W. The unlocked multiplier simplifies manual tuning, though excessive voltage can degrade the 7 nm silicon quickly. Common issues are forgotten BIOS updates and coolers that do not make full contact with the heatspreader.
