PredecessorFX

AMD officially announced a new series of processors, named "Ryzen", during its New Horizon summit on December 13, 2016 and introduced Ryzen 1000 series processors in February 2017 featuring up to eight cores and 16 threads with a 52% instructions per cycle (IPC) increase over their prior CPU products, which launched on March 2, 2017.[9] The second generation of Ryzen processors, the Ryzen 2000 series, features the Zen+ microarchitecture, an incremental improvement built on a 12 nm process technology from GlobalFoundries that was released in April 2018 and featured an average 10% total aggregate performance increase (≈3% IPC, 6% frequency, 10% overall[10]) over Ryzen 1000 processors[11] that first released in 2017. Most importantly though, Zen+ significantly improved cache and memory latencies, which were a major weak point of the original Zen design; this led to some particularly latency-sensitive workloads having IPC gains of nearly ≈10%.[12] The third generation of Ryzen processors launched on July 7, 2019 and based on AMD's Zen 2 architecture, features more significant design improvements with a 15% average IPC boost, a doubling of floating point capability to a full 256 bit wide execution datapath much like Intel's Haswell microarchitecture released in 2014[13] as well as a shift to an MCM style "chiplet" based package design, and a further shrink to Taiwan Semiconductor Manufacturing Company's (TSMC) 7 nm fabrication process. On June 16, 2020, AMD announced new Ryzen 3000 series XT processors with 100 MHz higher boost clocks versus non XT processors.[14] On October 8, 2020, AMD announced the highly anticipated Zen 3 architecture for their Ryzen 5000 series processors, featuring a 19% instructions per cycle (IPC) improvement over Zen 2, while being built on the same 7 nm TSMC node with out-of-the-box operating boost frequencies exceeding 5 GHz for the first time since AMD's Piledriver.[15][16] With the launch of Zen 3 via the Ryzen 5000 series, AMD took the lead in gaming performance over Intel, and this was an important milestone as gaming performance is usually correlated with single thread performance in terms of IPC.[17][18][19]

A majority of AMD's consumer Ryzen products use the Socket AM4 platform. In August 2017, AMD launched their Ryzen Threadripper line aimed at the enthusiast workstation market. AMD Ryzen Threadripper uses the larger TR4, sTRX4, and sWRX8 sockets, which support additional memory channels and PCI Express lanes. AMD plans to move to the new Socket AM5 platform for consumer desktop Ryzen with the release of Zen 4 products in late 2022.

In December 2019, AMD started producing first generation Ryzen products built using the second generation Zen+ architecture.[20] The most notable example is Ryzen 5 1600, with newest batches, having "AF" identifier instead of its usual "AE", being essentially a rebadged Ryzen 5 2600 with the same specifications as the original Ryzen 5 1600.

History
AMD Ryzen 7 3700X top and pins

Ryzen and the fundamental "Zen" CPU microarchitecture it uses were especially significant for AMD since it was a completely new, "from scratch" design and marked the corporation's return to the high-end CPU market after a decade of near-total absence since 2006.[21] This is because AMD's primary competitor Intel had largely dominated this market segment starting from the 2006 release of their Core microarchitecture (marketed as "Core 2-Duo"), after abandoning the Pentium 4's extremely uncompetitive Netburst microarchitecture (with AMD's Athlon XP in terms of price and efficiency and Athlon 64 & 64 X2 basically across the board) for an upgraded version of the prior Pentium 3, which notably continues to underpin Intel's CPU designs to this very day.[22]

Until Ryzen's initial launch in the Q2 of 2017, Intel's market dominance over AMD would only continue to increase as simultaneously with the above top-to-bottom launch of the now famous "Intel Core" CPU lineup and branding, was the successful roll out of their well known "tick-tock" CPU release strategy. This then brand new release strategy was most famous for alternating between a new CPU microarchitecture and a new fabrication node each and every year; with it being something that over time would become a release cadence they'd eventually manage to stick to for almost an entire decade (specifically lasting from Intel Core's initial Q3 2006 launch with 65 nm Conroe, all the way until their 14 nm Broadwell desktop CPUs were delayed a year from a planned 2014 launch out to Q3 2015 instead. This would necessitate a refresh of their pre-existing 22 nm Haswell CPU lineup in the form of "Devil's Canyon", and thus officially end "tick-tock" as a practice).[23][24] And it's for these same exact reasons that this became incredibly important for AMD, as Intel's inability to further sustain "tick-tock" past around 2014 would prove absolutely critical, if not downright essential in providing both the initial and continually growing market openings for their Ryzen CPUs and the Zen CPU microarchitecture in general to succeed.

Also of note is the release of AMD's Bulldozer microarchitecture in 2011, which despite being a clean sheet CPU design like Zen, had been designed and optimized for parallel computing above all else; which was then still very much in its infancy (which led to starkly inferior real-world performance in any workload that wasn't highly threaded), and thus ended up being uncompetitive in basically every area outside of raw multithread performance and its use in low power APUs with integrated Radeon graphics.[25] Despite a die shrink and several revisions of the Bulldozer architecture, performance and power efficiency failed to catch up with Intel's competing products.[26] Cumulatively, all of this practically forced AMD to abandon the entire high-end CPU market (including desktop, laptops, and server/enterprise) until Ryzen's release in Q2 2017.

Ryzen is the consumer-level implementation of the newer Zen microarchitecture, a complete redesign that marked the return of AMD to the high-end CPU market, offering a product stack able to compete with Intel at every level.[27][28] Having more processing cores, Ryzen processors offer greater multi-threaded performance at the same price point relative to Intel's Core processors.[29] The Zen architecture delivers more than 52% improvement in instructions per cycle (clock) over the prior-generation Bulldozer AMD core, without raising power use.[30] The changes to instruction set also makes it binary-compatible with Intel's Broadwell, smoothing the transition for users.[31]

Threadripper, which is geared for high performance desktops (HEDT), wasn't developed as part of a business plan or a specific roadmap; instead, a small enthusiast team inside AMD saw an opportunity that something could be developed between the Ryzen and Epyc CPU roadmaps that would put the crown of performance on AMD. After some progress was made in their spare time, the project was greenlit and put in an official roadmap by 2016.[32]

Since the release of Ryzen, AMD's CPU market share has increased while Intel's appears to have stagnated and/or regressed.[33]

CPUs

On May 27, 2019, at Computex in Taipei, AMD launched its third generation Ryzen processors which use AMD's Zen 2 architecture. For this generation's microarchitectures, Ryzen uses Matisse, while Threadripper uses Castle Peak. The chiplet design separates the CPU cores, fabricated on TSMC's 7FF process, and the I/O, fabricated on GlobalFoundries' 12 nm process, and connects them via Infinity Fabric.[110] The Ryzen 3000 series uses the AM4 socket similar to earlier models and is the first CPU to offer PCI Express 4.0 (PCIe) connectivity.[111] The new architecture offers a 15% instruction-per-clock (IPC) uplift and a reduction in energy usage. Other improvements include a doubling of the L3 cache size, a re-optimized L1 instruction cache, a larger micro-operations cache, double the floating point performance, improved branch prediction, and better instruction pre-fetching.[110] The 6-, 8- and 12-core CPUs became generally available on July 7, 2019, and 24-core processors were launched in November.[112]

The Ryzen Threadripper 3990X, part of Castle Peak generation of CPUs, has currently the world's largest number of both cores and threads available in consumer-oriented CPUs - 64 and 128, respectively. The competing Intel Core i9-10980XE processor has only 18 cores and 36 threads. Another competitor, the workstation-oriented Intel Xeon W-3275 and W-3275M, has 28 cores, 56 threads, and cost more when launched.

  5. Ryzen Threadripper 3990X may consume over 490 W under load.[132]

The 4-, 6- and 8-core processors have one core chiplet. The 12- and 16-core processors have two core chiplets. In all cases the I/O die is the same.[110]

The Threadripper 24- and 32-core processors have four core chiplets. The 64-core processor has eight core chiplets. All Threadripper processors use the same I/O die.

APUs

Both mobile and desktop APUs are based on the Picasso microarchitecture, a 12 nm refresh of Raven Ridge, offering a modest increase in clock speeds (up to an additional 300 MHz maximum boost), Precision Boost 2, an up to 3% increase in IPC from the move to the Zen+ core with its reduced cache and memory latencies, and newly added solder thermal interface material for the desktop parts.[139]

CPUs

In April 2022, AMD launched the Ryzen 4000 series of CPUs for budget-oriented users. Unlike the Ryzen 3000 series CPUs which are based on "Matisse" cores, these new Ryzen 4000 series desktop CPUs were based on "Renoir" cores and are essentially APUs with the integrated graphics disabled.

APUs

The Ryzen 4000 APUs are based on Renoir, a refresh of the Zen 2 Matisse CPU cores, coupled with Radeon Vega GPU cores. They were released only to OEM manufacturers in mid-2020. Unlike Matisse, Renoir does not support PCIe 4.0.[157]

Ryzen Pro 4x50G APUs are the same as 4x00G APUs, except they are bundled a Wraith Stealth cooler and are not OEM-only.[158] It is possible this is a listing mistake, since 4x50G CPUs are unavailable on retail (as of Oct. 2020) and PRO SKUs are usually the OEM only parts.

Ryzen 7000

In May 2022 AMD revealed its roadmap showing the Ryzen 7000 series of processors for release later that year, to be based on the Zen 4 architecture in 5 nm.[240][241] Included are DDR5 and PCIe 5.0 support as well as the change to the new AM5 socket.

Ryzen 8000

Ryzen 8000 was shown in May 2022 on AMD's Zen roadmap, to be based on the Zen 5 architecture,[240] and assumed to be in 3 nm by analysts.[242]

Initial reception

The first Ryzen 7 (1700, 1700X, and 1800X) processors debuted in early March 2017 and were generally well received by hardware reviewers.[243][244][245] 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.[246] 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] Though Zen fell short of Intel's Kaby Lake in terms of IPC, and therefore single-threaded throughput, it compensated by offering more cores to applications that can use them. Power consumption and heat emission were found to be competitive with Intel, and the included Wraith coolers were generally competitive with higher-priced aftermarket units.

Ryzen 1800X'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 that of the i7 7700K.[247] One reviewer found that Ryzen chips would usually outperform competing Intel i7 processors for a fraction of the price when all eight cores are used.[247]

However, one complaint among a subset of reviewers was that Ryzen processors lagged their Intel counterparts when running older games, or some newer games at mainstream resolutions such as 720p or 1080p.[248] AMD acknowledged the gaming performance deficit at low resolutions during a Reddit "Ask Me Anything" thread, where it explained that updates and patches were being developed.[249] Subsequent updates to Ashes of the Singularity: Escalation and Rise of the Tomb Raider increased frame rates by 17–31% on Ryzen systems.[250][251] In April 2017, developer id Software announced that, in the future, its games would exploit the greater parallelism available on Ryzen CPUs.[252]

It has been suggested that low threaded applications often result in Ryzen processors being underused, yielding lower than expected benchmark scores, because Zen relies on its core count to make up for its lower IPC rating than that of Kaby Lake.[253][254][255] However, AMD and others have argued thread scheduling is not the fundamental issue to Windows 10 performance.[256][257] Early AM4 motherboards were also hindered by BIOS bugs and poor DDR4 memory support.

Operating system support

Windows

AMD verified that computers with Ryzen CPUs can boot Windows 7 and Windows 8 both 64- and 32-bit but on newer hardware, including AMD Ryzen and Intel Kaby Lake and later, Microsoft only officially supports the use of Windows 10. Windows Update blocks updates from being installed on newer systems running older versions of Windows, though that restriction can be circumvented with an unofficial patch.[258]

Although AMD initially announced that Ryzen chipset drivers would not be provided for Windows 7,[259] its chipset driver packages do in fact list and include them.[260]

As of June 2021, first generation Ryzen CPUs, (excluding the newer Zen+ "AF" revisions) are not supported on Windows 11.[261][262]

Linux

Full support for Ryzen processors' performance features in Linux requires kernel version 4.10 or newer.[263]

Known issues

Spectre

Like nearly all modern high performance microprocessors, Ryzen was susceptible to the "Spectre" vulnerabilities. The vulnerabilities can be mitigated without hardware changes via microcode updates and operating system workarounds, but the mitigations incur a performance penalty.[264] AMD Ryzen and Epyc suffer up to 20% penalty from the mitigations,[265] depending on workload, comparing favorably with a penalty of in some benchmarks up to 30% for Intel Core and Xeon processors,[266][267] in part as a result of the AMD processors not requiring mitigation against the related Meltdown vulnerability.[268]

Launched in 2019, Zen 2 includes hardware mitigations against the Spectre V4 speculative store bypass vulnerability.[110][269]

Segmentation fault

Some early shipments of Ryzen 1000 series processors produced segmentation faults on some workloads on Linux, especially while compiling code with GNU Compiler Collection (GCC).[270] AMD offered to replace the affected processors with newer ones that are unaffected by the problem.[271]

Alleged issues by CTS Labs

In early 2018, Israeli computer security consultancy firm CTS Labs stated that they had discovered several major flaws in the Ryzen components ecosystem,[272] publicly disclosing them after giving AMD 24 hours to respond and raising concerns and questions regarding their legitimacy,[273][274] though they were later confirmed by two separate security firms.[275] AMD has since stated that while the flaws are real and will be fixed via microcode updates, their severity was overstated as physical access to the hardware is required to exploit the flaws.[276]
