AMD has added four new Ryzen 2000 (ZEN+) based procs, these include two E series SKUs (Ryzen 7 2700E and Ryzen 5 2600E) which are energy more energy efficient with a 45 Watt TDP.
The other two are the Ryzen 5 2500X and 2300X. The 2500X offers quad cores with eight threads and the and 2300X is quad-core/four threads.
Both newcomers are based internally on an Octacore-Die, which consists of two quad-core clusters (CCX) each with 8 MB L3 cache. For the 1500X and the 1300X AMD used a 2+2-configuration with 16 MByte, with the 2500X and with the 2300X this is the 4+0-variant with 8 MByte. No CCX-to-CCX latency occurs, thus these chips should/could perform a little better. But yes that does mean an 8MB L3 cache. The Ryzen 5 2600E (4c8t) and the Ryzen 7 2700E (8c/16t) are interesting for many long usage applications with a nice 45 W default TDP. The chips are able to do so as they have a lower base clock, 300-400 MHz lower. Manufacturers such as Acer have already listed them, Ryzen 5 2500X and the Ryzen 3 2300X are sold directly to OEMs. The chips are intended for inclusion into complete PCs, there are no prices.
I've placed the specs in the table below.
