Spotted on eBay for Sale for USD $176.
Although ‘engineering’ samples aren’t meant for sale/resale … there’s always a market for these chips.
Taken from Videocardz … AMD Ryzen 3 5300G is a quad-core desktop APU based on Zen3 architecture. The CPU is part of the Cezanne AM4 series that AMD has so far not even announced. Despite this rather unimportant fact, some eBay sellers are already offering the sample for sale. The CPUs that are being offered are engineering samples with a base clock of 3.5 GHz and an OPN code of 100-000000262-30_Y. The source of the samples is unknown, but it is common for CPU manufacturers to supply samples to motherboard makers and system integrators ahead of official introduction.
The description reveals that the CPU support is still rather limited. Many motherboards currently do not fully support Cezanne APUs. That said, there might be an issue with integrated graphics driver installation the seller claims. However, it is later mentioned that a fan has supplied a beta driver which is now being offered by the seller as well.
