AMD's entry-level Ryzen 3 4300G APU, which was being sold in the OEM/SI channels, is sneaking its way into the retail PIB space, with Japanese retailers listing it as a retail part. Until now, you could only get the 4300G as part of a pre-built, or as part of a retail "bundle," where they would simply pull one of these chips out of a tray, install it on an entry-level A520 or A320 chipset motherboard, and sell along with a stick of memory. The 4300G is commanding a roughly $100 (equivalent) price, which could make sense for entry-level mom-and-pop PCs.
The Ryzen 3 4300G is based on the 7 nm "Renoir" silicon, and is a Socket AM4 processor with integrated graphics. The processor has one of its two CCXs disabled, leaving you with a 4-core/8-thread CPU based on the "Zen 2" microarchitecture, that has 512 KB of L2 cache per core, and 4 MB of L3 cache shared among the four cores. The processor also features a dual-channel DDR4 memory interface, a PCI-Express Gen 3 interface, and an iGPU based on the Radeon "Vega" graphics architecture. It has a TDP of 65 W.
