Ryzen is an AMD brand for microprocessors. The brand was introduced in 2017 with products implementing their Zen microarchitecture.
First Ryzen-branded products were officially announced during AMD's New Horizon summit on December 13, 2016.
AMD's CEO, Lisa Su, confirmed during a March 2017 Reddit AMA on /r/AMD that Zen-based APUs would also be branded Ryzen. Traditionally, AMD's APUs were branded separately from their CPUs.
Although AMD "verified" the ability for computers with Ryzen processors to boot Windows 7 and Windows 10, Microsoft only officially supports Ryzen on computers running Windows 10 per support policies, and Windows Update blocks updates from being installed on Ryzen systems running versions older than Windows 10. In support of this position, AMD only provides drivers for Windows 10.
The first Ryzen 7 1700, 1700X, and 1800X processors debuted in early March 2017, and were generally well received by hardware reviewers. Ryzen was the first brand new architecture from AMD for five years, and without very much initial fine-tuning or optimization, it ran generally well for reviewers. Ryzen was found to be stable, with comparably few performance or BIOS bugs. Initial Ryzen chips ran well with software and games already on the market, performing exceptionally well in workstation scenarios, and well in most gaming scenarios. Compared to Piledriver-powered FX chips, Zen-powered Ryzen chips ran cooler, much faster, and used less power. IPC uplift was eventually gauged to be 52% higher than Excavator, which was two full generations ahead of the architecture still being used in AMD's FX-series desktop predecessors like the FX-8350 and FX-8370. Power consumption and heat were found to be highly competitive with Intel, and the included Wraith coolers were generally competitive with higher-priced aftermarket solutions.
Ryzen's multi-threaded performance, in some cases while using Blender or other open-source software, was around four times the performance of the FX-8370. One reviewer found that Ryzen chips would typically outperform competing Intel i7 processors for a fraction of the price when all eight cores were utilized.
