March 02, 2017: AMD’s highly anticipated Ryzen CPU was officially launched and lives up to the hype. It delivers a very good value at an unbeatable price: $499 for the highest-end Ryzen 7 1800X. That’s half the price of its closest Intel competitor.
The failure of Bulldozer made AMD lagging behind for years, left the high end market to Intel and pursuing on an ARM CPU for servers. In fact, the last time AMD had a truly competitive CPU, George W. Bush was still the President of USA. It's a long time ago, in the galaxy far, far away :D
Ryzen is very different from its predecessor. The AMD FX (Bulldozer) CPUs used a technique called clustered multithreading (CMT) that shared key components of the chip; they were built on an uncompetitive 32nm, and later 28nm process.
With Ryzen, AMD rebooted its CPU design, adopted a technique called simultaneous multithreading (SMT), which virtualizes CPU resources. Ryzen CPUs are built on a state-of-the-art 14nm process by AMD’s spun-off fab, Global Foundries.

AMD has already said Ryzen exceeds its goal of a 40-percent increase over previous designs—in fact, it has hit a 52-percent increase in clock-for-clock performance over the Piledriver cores. But the most important you want to know is how well it does against Intel.
Well, reviews and benchmarks already flooded the web...Check it out!
