Quote:Despite AMDs resurgence to kick it with the high end of mainstream processors, the biggest volume sales occur more in the mid-range where the parts are often competitively priced. In the segment, AMD currently has the Ryzen 5 2600 and the 2400G at retail, but OEMs can use two others: the 2500X and the 2300X. We don't know if we'll ever see these at retail, but we obtained both CPUs for a review.

[b]AMD’s Ryzen 2500X and Ryzen 3 2300X: Filling in Some Gaps
[/b]
Much like the first gen counterparts, the 2500X is a quad core processor with simultaneous multi-threading while the 2300X is a straight forward quad core. The X processors usually have a higher thermal design power (TDP) than hypothetical non-X equivalents, allowing them to take advantage of AMDs Extreme Frequency Range technology for higher turbos for longer given sufficient cooling, although these are set at 65W, similar to non-X processors. Normally X processors come with better stock coolers at retail, however as these are OEM only processors, it is up to the system integrator to provide sufficient cooling.

Both of these processors use AMD's Zen+ microarchitecture, built on GlobalFoundries' 12nm manufacturing process node. This means it has better voltage, frequency, and power characteristics over the first generation Ryzen, allowing them to run faster at the same power, or cooler at the same performance. AMD has also applied minor tweaks to the design, which gives the processor an additional 3% performance at the same frequency to first generation Ryzen. We tested and verified these claims in our review of AMD's first Zen+ processors.
