The AMD Ryzen 2000 series of CPUs were released in 2018 as the successor to the highly successful Ryzen 1000 series. These CPUs were designed to build upon the success of their predecessor, with improved performance and new features. The Ryzen 2000 series comprises of three different CPUs, each with their own unique specifications and capabilities.

Here is a list of the Ryzen 2000 series CPUs:

1. AMD Ryzen 7 2700: This is an 8-core, 16-thread CPU with a base clock speed of 3.2GHz and a boost clock speed of 4.1GHz. It has a TDP of 65W and comes with a Wraith Spire cooler.
2. AMD Ryzen 7 2700X: This is an 8-core, 16-thread CPU with a base clock speed of 3.7GHz and a boost clock speed of 4.3GHz. It has a TDP of 105W and comes with a Wraith Prism cooler.
3. AMD Ryzen 5 2600: This is a 6-core, 12-thread CPU with a base clock speed of 3.4GHz and a boost clock speed of 3.9GHz. It has a TDP of 65W and comes with a Wraith Stealth cooler.

The Ryzen 2000 series CPUs are based on the same Zen architecture as their predecessor, but with improvements in performance, power consumption, and efficiency. They also support DDR4 memory and PCI-Express 3.0, and are compatible with the AM4 socket.

One of the major improvements in the Ryzen 2000 series CPUs is their higher clock speeds, which provide a significant boost in single-threaded performance. The Ryzen 7 2700X, for example, has a base clock speed that is 500MHz higher than the Ryzen 7 1700X, its predecessor.

In addition to improved performance, the Ryzen 2000 series CPUs also offer excellent value for money. The Ryzen 5 2600, for example, offers a level of performance that is comparable to much more expensive CPUs, but at a much lower price point.

In conclusion, the AMD Ryzen 2000 series of CPUs are a great choice for anyone looking to build a new PC or upgrade their existing one. With improved performance, efficiency, and value for money, these CPUs are a solid choice for users who want the best of both worlds.
