Four models have been announced, two Ryzen 5 and two Ryzen 7, are all available for pre-order and will go on sale on April 19th.

Today's launch comes with very little information. All we know for now are the basic specifications of the four new SKUs. We are not entirely sure of the range of differences between first and second generation Ryzen processors. All this and more will be revealed on April 19.

Let's talk about what we know today. The four SKUs launched include Ryzen 7 2700X and Ryzen 7 2700 in the high end and Ryzen 5 2600X and Ryzen 5 2600 in the popular mid-range segment. All new processors use a 12 nm process based on the new Zen architecture.

The top of the range is the 2700X with 8 cores and 16 threads, basic 3.7 GHz clock and 4.3 GHz boost clock. It has 20 MB of "Smart Prefetch Cache", which is 4 MB of L2 cache and 16 MB of L3 cache. The TDP is 105 W. The 2700X comes with a new Wraith Prism sink with RGB backlit transparent fans and four direct-contact copper heatpipes. It's priced at 329 dollars.

The 2700 also has the 8/16 core/thread count and the same cache amount but has a base clock/boost speed of 3.2 GHz/4.1 GHz lower and a lower TDP of 65 W. It comes with the Wraith Spire cooler with RGB ring and at a price of $299.

The 2600X is a 12-core 6-thread processor with a combined 19 MB cache, 3.6 GHz base, and 4.2 GHz clock boost speed. It has a TDP of 95 W, comes with the standard Wraith Spire cooler and is priced at $229.

Finally, the 2600 has the same number of cores, threads and caches as the 2600X but 3.4 GHz / 3.9 GHz of basic clock/boost speed and 65 W TDP. It comes with the basic Wraith Stealth cooler and has a price tag of $199.

Along with the new CPU, AMD also announced the X470 motherboard chipset. Again, we don't know much about the new chipset and how it differs from the X370. Fortunately, you can still use the new CPU with last year's older AMD chipsets and the older CPU can work with the new X470 cards. OEMs such as ASRock, ASUS, Gigabyte and MSI will soon announce their cards with the new chipset.

More details will be revealed on April 19th.
