After floundering for the last five years with their Bulldozer architecture and its derivatives, AMD is releasing processors based on a new architecture called Zen. The Ryzen CPUs, starting with the high end chips launching this March, have been made to tackle Intel head on.
On March 2nd AMD is releasing three high end CPUs aimed at gamers, content creators, and enthusiasts, all with 8 cores and 16 threads. The Ryzen 7 1800X is the flagship with a base clock of 3.6GHz, a boost speed of 4.0GHz, a TDP of 95W, and retails for $500. AMD is claiming that this chip will outperform Intel's core i7 6900K by 9% in multi threaded work and is dead even in single thread performance. The 6900K is also an 8 core/16 thread CPU, has a clock speed of 3.2GHz and a turbo of 3.7GHz. It'll also run you about $1050.
In the middle is the 1700X with a base clock speed of 3.4GHz and a 3.8GHz boost clock. This is also a 95W TDP chip. AMD claims this will significantly outperform the core i7 6800K, which has 2 fewer cores, in multi threaded workloads by 39%. The 1700X will cost slightly less at $400 compared to about $425 for the 6800K.
Finally, the 1700 rounds out the high end. For $330 you're getting a CPU with a base clock of 3.0GHz, a boost speed of 3.7GHz, and a TDP of only 65W. Intel's core i7 7700K ($350), which AMD is choosing to compare to, only has 4 cores and a TDP of 91W. The i7's 4.2GHz clock and 4.5GHz turbo will be faster in single threaded performance, but AMD is claiming up to 46% better performance in multi threaded applications.
Later this year AMD will also release chips for the Ryzen 5 class, which sits in the middle, and the Ryzen 3 class, which will be more budget oriented. Leaked benchmarks of the Ryzen 5 1600X, a 6 core/12 thread CPU, show it outperforming many i7 processors, so that's definitely something to look out for in a few months.
