With the April 19 introduction of four new second-generation Ryzen "Pinnacle Ridge" desktop processor SKUs, namely the 2700X, 2700, 2600X, and 2600; AMD is retiring six first-generation "Summit Ridge" SKUs from its lineup, according to a Guru3D report. Six SKUs have been marked EOL (end of life), meaning retailers can no longer order them from AMD. They can sell their remaining inventory, and AMD will honor full product warranties and aftersales support, to end users.

Among the retired SKUs are the previous-generation flagship Ryzen 7 1800X, 1700X, and 1700 (non-X); Ryzen 5 1600X, 1400, and the Ryzen 3 1200. As revealed in its product stack slide, the 2700X currently replaces both the 1800X and 1700X as the "8-core high performance" SKU, followed by the 2700 as the "8-core high efficiency" SKU, which replaces the 1700. The 2600X and 2600 succeed the 1600X and 1600, respectively. The Ryzen 5 1400 finds itself replaced by the GPU-equipped Ryzen 5 2400G "Raven Ridge" APU, and the entry-level Ryzen 3 1200 by the sub-$100 Ryzen 3 2200G. The table below reveals the updates prices of first-generation SKUs still in the product stack.
