Ryzen (/ˈraɪzən/ RY-zən)[2] is a brand[3] of x64 and x86 microprocessors designed and marketed by AMD (Advanced Micro Devices) for desktop, mobile and embedded platform based on Zen and Zen+ microarchitectures. It consists of central processing units marketed for mainstream, enthusiast and workstation segments and accelerated processing units (APUs) which is marketed for mainstream and entry-level segments and embedded applications.

Ryzen was introduced in February 2017 with the first products officially announced during AMD's New Horizon summit on December 13, 2016, feature the Zen microarchitecture.[4] The second generation of Ryzen CPUs feature the Zen+ microarchitecture, built with 12 nm process technology and were released on April 19, 2018.[5]

History

In the five years before the release of Ryzen, AMD's direct competitor in the x86 and x64 consumer-level CPU marketspace, Intel, had continued to grow its market share with the tick-tock cycle of their Intel Core series of chips.[6] Since the release of Bulldozer microarchitecture in 2011, AMD CPUs had fallen behind Intel Core architecture in both single- and multi-core performance,[7] which resulted in poor sales. While AMD had completed a die shrink and several revisions of the Bulldozer architecture, performance and efficiency still fall behind Intel's competing products.[citation needed] Ryzen is the first consumer-level implementation of the newer Zen microarchitecture.[8][9] The release of Ryzen marked a return for AMD in the high-end desktop CPU market, offering a product able to compete with Intel's high-end desktop variants of Core i7 series of processors. High performance Ryzen processors offered greater multi-threaded performance at the same price point relative to Intel's Core processors.[10] AMD's high-performance x86-core Zen architecture delivers >52% improvement in instructions-per-clock cycle over the previous-generation AMD core, without increasing power consumption.[11] Since the release of Ryzen, AMD's CPU market share has increased.[6]

CPUs: Summit Ridge / Whitehaven

  • Socket AM4 or Socket TR4 for Ryzen Threadripper.[12][13]
  • Memory support DDR4-2666 ×2 Single Rank, DDR4-2400 ×2 Dual Rank, DDR4-2133 ×4 Single Rank, or DDR4-1866 ×4 Dual Rank. (With compatible DIMM quantities doubled on Threadripper due to its dual IMCs, and thus quad-channel memory support).[12][14]
  • Instructions Sets: x87, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, CLMUL, AVX, AVX2, FMA3, CVT16/F16C, ABM, BMI1, BMI2, SHA.[15]
  • Transistors: 4.8 billion per 8-core "Zeppelin" die[1]
  • Die size: 192 mm2[16]
  • Stepping: B1[17]
  • Ryzen CPUs feature unlocked multipliers across the board for overclocking. All Ryzen products also support temperature-based auto-overclocking, dubbed "XFR" (eXtended Frequency Range); with "X"-branded Ryzen products having twice the potential amount of XFR boost as non-"X" models (100 MHz vs 50 MHz).[18] This is despite the fact that AMD doesn't list the latter as supporting XFR at all. Also of note that these values are doubled on Threadripper; with "X" models having 200 MHz, rather than the usual 100 MHz of XFR boost.[19]
  • AMD officially revealed their codename "Summit Ridge" Ryzen CPUs on February 22, 2017.[20] "Whitehaven" is planned to be a large, LGA "S3" socket, HEDT (high-end desktop) variant with 16 cores and 32 threads.[21]
  • Ryzen is launching in conjunction with a line of stock coolers for Socket AM4, the "Wraith Spire", "Wraith Stealth" and "Wraith Max". This line succeeds the original "Wraith" cooler, which was positively received when released in mid-2016.[22] The "Wraith Stealth" and "Wraith Spire" are included with certain Ryzen CPUs; the "Stealth" is a low-profile unit meant for the lower-end CPUs and is rated for a TDP of 65 W, whereas the "Spire" is the mainstream cooler with a TDP rating of 95 W and modest headroom for overclocking, along with optional RGB lighting on certain models. The "Wraith Max" is a larger, aftermarket unit intended to handle more intensive overclocks than the "Spire".
  • AMD's SenseMI Technology, which uses AMD Infinity Control Fabric to offer the following features:[12][23][24]
    • 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 by 100–200 MHz if three or more cores are active (five or more, in the case of Threadripper, and by 300 MHz); and significantly further when less than three are active (less than five, in the case of Threadripper).[25][26]
    • AMD XFR ("eXtended Frequency Range") increases the processor voltage and clock speed beyond the maximum Precision Boost, when sufficient cooling is available (described in detail above).[27]
    • Neural Net Prediction and Smart Prefetch use perceptron based neural branch prediction 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.
  • All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset.
  • No integrated graphics.
  • L1 cache: 96 KB (32 KB data + 64 KB instruction) per core.
  • L2 cache: 512 KB per core.
  • Node/fabrication process: GlobalFoundries 14 LP.

APUs: 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.[32] Traditionally, AMD's APUs were branded separately from their CPUs. The branding was later clarified as Ryzen Mobile, and AMD stated that the products would have higher CPU and GPU performance and lower power than the previous generation of APUs.[33]

In May 2017, AMD demonstrated a Ryzen Mobile APU with four Zen CPU cores and Vega-based GPU,[34] the first Ryzen Mobile APUs were officially released in October 2017.[35] It is the first chip by AMD that features the Video Core Next ASIC.

Zen 2 microarchitecture

Main article: Zen 2

CPUs: Matisse

On January 9, 2019 during a CES keynote event[66], AMD CEO Lisa Su gave an early look at third-generation Ryzen desktop processors. Su showed in-hand an exposed eight-core Zen 2 desktop processor utilizing a chiplet design composed of a larger 14 nm I/O die and a separate, smaller 7 nm CPU die. An on-stage team of employees also demonstrated a test system with an eight-core Zen 2 desktop processor achieving multithreaded performance directly comparable to the Intel Core i9-9900K in Maxon Cinebench R15 while consuming 30% less total system power.[67] Later that day in a question and answer session, Su confirmed that the unused space on the processor package would be used for an additional CPU chiplet, bringing the maximum total core count to an unspecified quantity in excess of eight cores.[68]

Initial reception

The first Ryzen 7 (1700, 1700X, and 1800X) processors debuted in early March 2017 and were generally well received by hardware reviewers.[69][70][71] 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.[72] 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.[1] 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, or nearly double of the i7 7700K.[73] 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.[73]

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.[74] AMD acknowledged the gaming performance deficit at low resolutions during a Reddit "Ask Me Anything Q & A thread", where they explained that updates and patches were being developed.[75] Subsequent updates to Ashes of the Singularity: Escalation and Rise of the Tomb Raider increased frame rates 17–31% on Ryzen systems.[76][77] id Software announced in April 2017 it would optimize its future games to make use of the greater parallelism available on Ryzen CPUs.[78]

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 lower IPC relies on full core utilization.[79][80][81] However, AMD and others have argued thread scheduling is not the fundamental issue to Windows 10 performance.[82][83] 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]

Operating system support

Although AMD verified the ability for computers with Ryzen processors to boot Windows 7 and Windows 8, Microsoft does not officially support older versions of Windows on newer processors including AMD Ryzen and Intel Core i3/i5/i7 (Kaby Lake and later). Windows Update blocks updates from being installed on newer systems running versions older than Windows 10 – although that restriction can be avoided either by not installing its respective update, or be bypassed entirely with an unofficial patch.[84]

AMD initially announced that Ryzen chipset drivers would not be provided for Windows 7,[85] but AMD's Ryzen and Threadripper chipset driver packages do list and include official drivers for Windows 7.[86]

Ryzen processors are compatible with Linux; the full performance of Ryzen is enabled in kernel version 4.10 or newer.[87]

Known issues

Spectre

Substantially all modern high performance microprocessors, including Ryzen, were found to be vulnerable to a new category of speculative execution vulnerabilities. The vulnerabilities can be mitigated without hardware changes via microcode updates or operating system workarounds, but the mitigations incur a performance penalty.[88] AMD Ryzen/Epyc suffer a zero to nine percent penalty from the mitigations depending on workload, comparing favorably to a penalty of in some cases more than 50% for Intel Core/Xeon processors,[89][90] in part as a result of the AMD processors not requiring mitigation against the related Meltdown vulnerability.[91]

AMD has announced that Zen 2, expected in 2019, will include a hardware fix.[92]

Segmentation Fault

Some early shipments of Ryzen 1000 series processors produced segmentation faults on certain workloads on Linux, especially while compiling code with GCC.[93] AMD offered to replace the affected processors with newer ones that are not affected by the problem.[94]

Alleged issues by CTS Labs

In early 2018, an Israeli firm called CTS Labs claimed to have discovered several major flaws in the Ryzen components ecosystem: Ryzenfall, which affects the Ryzen desktop CPUs; Fallout, which affects the Epyc CPUs; Masterkey, which affects both CPU classes; and Chimera, which affects the ASMedia-designed USB 3.1 silicon found in the Ryzen desktop SoCs.[95] The unusual behavior of the security firm, disclosing the vulnerabilities without giving AMD time to react, has raised concerns and questions regarding the legitimacy of the exploits.[96]

Further questions were raised when independent investigators dug into the history of the company and analyzed the video they have uploaded to the web.[97] Ultimately, investigators uncovered an article by Viceroy Research condemning AMD on the exploit and noted how the article was published less than half an hour after the exploits were revealed. Given the polish of the article which appears to be written many days in advance, and wording of the article which suggests that it is financially motivated, many were quick to accuse the exploit as a smear campaign engineered by Viceroy to short-sell AMD's stocks.[98]

AMD had since announced that while the exploits are real, they are severely overplayed as physical access to the server is required to exploit the flaws. AMD has also announced that the flaws can be fixed via microcode updates and that they are working on a fix for the issue.[99]
