AMD has announced four new 2000-series processors based on Zen+ which fills out its launch of parts: two X-series processors at 65W focused on overclocking with Precision Boost overdrive, and two E series parts at 45W.

Strangely enough, AMD's announcement today only had the two X processors, but the E processors were included in their official tables. The launch of the X processors seems to be coinciding with the new Acer Nitro system. 

Both the 2500X and 2300X, at quad core/eight threads and quad core/four threads will feature a single enabled CCX, rather than a 2+2 configuration. This also means that the L3 cache of the new X parts is only 8MB, rather than 16MB, but AMD is quoting an 8-10% gain in performance over the previous generation for these parts. AMD also confirmed these new parts support DDR4-2933. Neither X series processor will be bundled with a cooler.

AMD’s Ryzen 5 2600E and the Ryzen 7 2700E are the company’s first eight and six-core CPUs featuring a 45 W default TDP. The new processors enable PC makers to build small form-factor desktops that do not need high-performance cooling. The chips are clocked at 300-400 MHz below their 65 W counterparts. At the same time, the Ryzen 5 2600E and the Ryzen 7 2700E still have the cache as the higher rated parts, but will not support Precision Boost Overdrive.

Prices have yet to be disclosed, however AMD has said that these processors are 'immediately available', at least through the Acer system.

Update

AMD has confirmed that the two X series processors will be OEM only parts for the time being, and subsequently will not have specific pricing listed.
