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 at /r/AMD that Zen-based APUs would also be branded Ryzen. Traditionally, AMD's APUs were branded separately from their FX-branded CPUs.
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 especially 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 much more 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.
One complaint among a subset of reviewers, however, was that Ryzen processors fell behind their Intel counterparts when running older games, or running newer games at mainstream resolutions such as 720p or 1080p. Shortly after these lower-resolution benchmarks were released and began to attract controversy, tech journalist AdoredTV released a refutation YouTube and explained how and why low-resolution benchmarks incorrectly predict how games will run when the CPU is bottlenecked, and also demonstrated how they had been previously used to incorrectly predict how AMD's early FX chips would perform in the future. AMD acknowledged the gaming performance deficit at low resolutions during a Reddit AMA, where they explained that updates and patches were in the works.
