Ryzen

Ryzen (/ˈraɪzən/ RY-zən)[3] is a brand[4] of x86-64 microprocessors designed and marketed by Advanced Micro Devices, Inc. (AMD) for desktop, mobile and embedded platforms based on the Zen microarchitecture and its successors. It consists of central processing units marketed for mainstream, enthusiast and workstation segments and accelerated processing units (APUs) marketed for mainstream and entry-level segments and embedded applications. Ryzen is especially significant for AMD, since it is a completely new design, and since it marks the corporation's return to the high end desktop CPU market. AMD's competitor Intel has controlled this section of the market for almost ten years, back when Intel released the Conroe/Core microarchitecture, which overtook AMD's Athlon 64 as the cutting edge of performance in the market.

History
PredecessorFX

AMD officially announced the first 14nm Ryzen products during its New Horizon summit on December 13, 2016 and introduced them the following February with the first processors being 8-core, 16 thread CPUs released in March 2 2017 to public market availability as the Ryzen 1000 series.[5] The second generation of Ryzen CPUs featuring the Zen+ microarchitecture, an incremental improvement built on a 12nm process technology, was released in April 2018 and featured a 3% IPC and 6%[6] uplift in clockspeed respectively with up to 10% aggregate performance increase over the original Ryzen that first released in 2017 with Ryzen 2000 series branding.[7] The third generation, based on Zen 2 and featuring more significant design improvements and a further shrink to TSMC's 7nm process, was launched on July 7 2019, powering the Ryzen 3000 series, and featured a self-reported 15% IPC increase. In late 2019, the Zen 3 core has been revealed to be an entirely new architecture rumored to be built on TSMC's 7nm+ EUV node (though all that's officially confirmed at this point is the use of an "enhanced 7nm" process), which is currently undergoing engineering sampling as of Q4 2019 with production yields exceeding expectations.

While the majority of Ryzen-branded products are for use with the Socket AM4 platform, in August 2017 AMD added a line of high core count desktop processors aimed at the workstation market with the Ryzen Threadripper branding. Threadripper uses the larger TR4 and sTRX4 sockets, which support more memory channels and PCI Express lanes.[8][9]

In December 2019, AMD started putting out first generation Ryzen products built using the second generation Zen+ architecture.[10] 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

In the five years before the release of Ryzen, AMD's direct competitor in the x86 and x86-64 consumer-level CPU marketspace, Intel, had continued to grow its market share with the tick-tock improvement cycle of its Core series of microprocessors.[11] Since the release of its Bulldozer microarchitecture in 2011, AMD's CPUs had fallen progressively behind those from Intel in both single- and multi-core performance.[12] Despite a die shrink and several revisions of the Bulldozer architecture, performance and power efficiency failed to catch up with Intel's competing products.

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.[13][14] Having more processing cores, Ryzen processors offer greater multi-threaded performance at the same price point relative to Intel's Core processors.[15] The Zen architecture delivers more than 52% improvement in instructions-per-clock cycle over the previous-generation Bulldozer AMD core, without increasing power consumption.[16] The changes to instruction set also makes it binary-compatible with Intel's Broadwell, smoothing the transition for users.[17]

Threadripper, which is geared for high end 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.[18]

Since the release of Ryzen, AMD's CPU market share has increased while Intel appears to have stagnated.[11]

Ryzen 3000

CPUs

On May 27, 2019, AMD launched its third generation of Ryzen processors using its chiplet-based Zen 2 architecture at Computex in Taipei. In this generation, Ryzen CPUs utilize the Matisse microarchitecture, while Threadrippers are based on the Castle Peak microarchitecture. The chiplet design separates the CPU cores, fabricated on TSMC's 7FF process, and the I/O, fabricated on GlobalFoundries' 12nm process, and connects them via Infinity Fabric.[107] The Ryzen 3000 series uses the same AM4 socket as earlier models and is the first CPU to offer PCIe version 4 connectivity.[108] 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 op. cache, double the floating point performance, improved branch prediction, and better instruction pre-fetching.[107] The six-, eight- and 12-core SKUs became generally available on July 7, 2019. On September 20, 2019 AMD announced that third generation Ryzen Threadripper processors with core counts starting at 24 would be launched in November.[109]

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 and 56 threads and were more expensive when launched.

Initial reception

The first Ryzen 7 (1700, 1700X, and 1800X) processors debuted in early March 2017 and were generally well received by hardware reviewers.[155][156][157] 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.[158] 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 were found to be highly competitive with Intel, and the included Wraith coolers were generally competitive with higher-priced aftermarket solutions.

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.[159] 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.[159]

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.[160] 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.[161] Subsequent updates to Ashes of the Singularity: Escalation and Rise of the Tomb Raider increased frame rates by 17 to 31% on Ryzen systems.[162][163] Publisher id Software announced in April 2017 it would optimize its future games to make use of the greater parallelism available on Ryzen CPUs.[164]

It has been suggested that low threaded applications often result in Ryzen processors being underutilized, producing lower than expected benchmark scores, due to the fact that Zen relies on its core count to make up for its lower IPC rating than that of Kaby Lake.[165][166][167] However, AMD and others have argued thread scheduling is not the fundamental issue to Windows 10 performance.[168][169] 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 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.[170]

Although AMD initially announced that Ryzen chipset drivers would not be provided for Windows 7,[171] its chipset driver packages do in fact list and include them.[172]

Linux

The full performance of Ryzen processors is available with Linux kernel version 4.10 or newer.[173]

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.[174] AMD Ryzen and Epyc suffer a zero to 9% penalty from the mitigations, depending on workload, comparing favorably with a penalty of in some cases more than 50% for Intel Core and Xeon processors,[175][176] in part as a result of the AMD processors not requiring mitigation against the related Meltdown vulnerability.[177]

Launched in 2019, Zen 2 includes hardware mitigations against the Spectre V4 speculative store bypass vulnerability.[107][178]

Segmentation fault

Some early shipments of Ryzen 1000 series processors produced segmentation faults on certain workloads on Linux, especially while compiling code with GCC.[179] AMD offered to replace the affected processors with newer ones that are not affected by the problem.[180]

Alleged issues by CTS Labs

In early 2018, an Israeli cyber-security consultancy firm called CTS Labs stated that they had discovered several major flaws in the Ryzen components ecosystem,[181] publicly disclosing them after giving AMD 24 hours to respond and raising concerns and questions regarding their legitimacy,[182][183] though they were later confirmed by two separate security firms.[184] AMD has since stated that while the flaws are real and would be fixed via microcode updates, they were severely overplayed as physical access to the hardware is required to exploit them.[185]
