AMD Tuesday expanded its 3rd generation Ryzen desktop processor lineup with two new product additions, the 12-core/24-thread Ryzen 9 3900, and the 6-core/12-thread Ryzen 5 3500X. Both chips are particularly interesting given their naming. The 3900 is a slightly subdued twin of the company's current flagship, the 3900X, with a small amount of clock speed traded off for a huge drop in TDP. This chip ticks at 3.10 GHz with 4.30 GHz boost, compared to 3.80/4.60 GHz frequencies of the 3900X. Its TDP, however, is rated at just 65 W, compared to 105 W of the 3900X. You get 512 KB of dedicated L2 cache per core, and 64 MB of L3 cache.

The Ryzen 5 3500X is another interesting part, in which the "X" makes a world of difference from the Ryzen 5 3500. Whilst the 3500 is a 6-core/6-thread part devoid of SMT, the 3500X is 6-core/12-thread (features SMT), has the same exact 3.60 GHz nominal clocks as the popular Ryzen 5 3600, but a slightly lower 4.10 GHz boost frequency, compared to 4.20 GHz of the 3600. The Ryzen 5 3500X is expected to be marginally cheaper than the 3600, at around $189, and is currently only being offered to OEMs and system integrators in China. The company hasn't finalized pricing for the 3900, yet.

AMD will soon launch its budget CPU offerings from Ryzen 3000 series of CPUs to continue the tradition of covering all market segments. Today, Ryzen 5 3500X CPU has appeared in listing at Chinese retailer called JD which showed off CPU's pricing information and specifications. Coming in with a price tag of 1099 yuan (around $155), newly listed Ryzen 5 3500X is supposed to be a higher clocked variant of unannounced Ryzen 5 3500 CPU.

Featuring six cores and six threads, this CPU seems to have similar specs as Ryzen 5 3600 with the only difference being the disabled SMT support and slightly lower boost speeds. It has a 3.6 GHz base and 4.1 GHz boost frequency, all while having TDP of 65 Watts. Amount of L3 cache stays the same as its bigger, SMT enabled, variant which features 32 MB of GameCache. Additionally, JD also included some graphs where Ryzen 5 3500X was compared to Intel's i5-9400F CPU at various games, using NVIDIA's GeForce GTX 1660 graphics card. Bellow are the benchmarks comparing the two CPU offerings:
