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.[1]

Multi-GPU
  • All models require AMD Socket AM4.[2][3]
  • All models support DDR4-2666 ×2 Single Rank, DDR4-2400 ×2 Dual Rank, DDR4-2133 ×4 Single Rank, or DDR4-1866 ×4 Dual Rank.[2][4]
  • All models support: x87, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, CLMUL, AVX, AVX2, FMA, CVT16/F16C, ABM, BMI1, BMI2, SHA.[5]
  • Transistors: 4.8 billion[6]
  • Die size: 192 mm² [7]
  • Stepping: B1[8]
  • Ryzen CPUs feature unlocked multipliers across the board for overclocking. All Ryzen products support auto-overclocking, dubbed "XFR", with X branded Ryzen products giving twice the XFR boost as non-X branded Ryzen products,[9] although AMD does not list non-X branded Ryzens having XFR.[10]
  • AMD officially revealed their codename "Summit Ridge" Ryzen CPUs on February 22, 2017.[11] Ryzen CPUs differ from Zen-powered APUs in that they exclude an integrated GPU and instead rely on an external, dedicated one.
  • Some Ryzen CPUs will include upgraded versions of the "Wraith" stock cooler, namely "Wraith Spire", "Wraith Stealth" and "Wraith Max". The original "Wraith" cooler was positively received when released in mid-2016.[12] The new coolers will have RGB lighting with the exception of the "Wraith Stealth" cooler. The "Wraith Max" cooler will be optionally included with X models, the "Wraith Spire" cooler will be included with the Ryzen 7 1700, Ryzen 5 1600, and Ryzen 5 1500X (the Ryzen 7 1700 cooler has RGB lighting, while the Ryzen 5 coolers do not), and the "Wraith Stealth" cooler will be included with the Ryzen 5 1400.[citation needed]
  • All models support AMD SenseMI Technology, which uses AMD Infinity Control Fabric to offer the following features.[2][13][14]
    • AMD Pure Power reduces the entire ramp of processor voltage and clock speed, for light loads.
    • AMD Precision Boost increases the processor voltage and clock speed while the number of active cores <= 2.
    • AMD XFR (eXtended Frequency Range) increases the processor voltage and clock speed beyond the maximum Precision Boost, while sufficient cooling is available.[15]
    • Neural Net Prediction and Smart Prefetch use true AI inside the processor to optimize instruction workflow and cache management.

Common features of Ryzen 1000 desktop CPUs:

  • Socket: AM4.
  • All the CPUs support DDR4-2666 in dual-channel mode.
  • L1 cache: 96 KB (32 KB data + 64 KB instruction) per core.
  • L2 cache: 512 KB per core.
  • All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset.
  • No integrated graphics.
  • Node/fabrication process: GlobalFoundries 14 LP.

Raven Ridge

AMD's CEO, Lisa Su, confirmed during a March 2017 Reddit AMA on /r/AMD that Zen-based APUs would also be branded Ryzen.[17] Traditionally, AMD's APUs were branded separately from their CPUs.

Compatibility

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. 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.[18]

Initial reception

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 in five years, and without very much initial fine-tuning or optimization, it ran generally well for reviewers.[19] Ryzen was found to be stable, with comparably few performance or BIOS bugs.[citation needed] 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.[20] 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.[21] 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.[21]

One complaint among a subset of reviewers, however, was that Ryzen processors fell behind their Intel counterparts when running older games, or running certain newer games at mainstream resolutions such as 720p or 1080p.[22] AMD acknowledged the gaming performance deficit at low resolutions during a Reddit AMA,[vague] where they explained that updates and patches were in the works.[23] A subsequent update to Ashes of the Singularity: Escalation increased frame rates 17−31% on Ryzen systems.[24] id Software announced in April 2017 it would be optimizing its future games to make use of the greater parallelism available on the Ryzen CPU.[25]

It has been suggested that low core utilization resulted in Ryzen processors being underutilized, therefore reflecting lower than expected scores, especially when coupled with the fact that Zen's slightly lower IPC relies on full core utilization.[26][27][28] However, AMD and others have argued thread scheduling is not the fundamental issue to Windows 10 performance.[29][30] There were also issues with AM4 motherboards and their BIOS, which was resulting in many Ryzen chips being underclocked, partially shut off, or generally hindered by BIOS bugs.[citation needed]

Known issues

The UEFI shipped with Ryzen compatible motherboards leads to hard system locks when an application executes certain sequences of FMA3 instructions.[31] AMD stated in mid March 2017 that the issue would be fixed via an update from motherboard manufacturers.[citation needed]
