Ryzen (/ˈraɪzən/ RY-zən)[3] is a brand[4] of multi-core x86-64 microprocessors, designed and marketed by AMD for desktop, mobile, server, and embedded platforms, based on the Zen microarchitecture.

The delay necessitated a refresh of their pre-existing 22 nm Haswell CPU lineup in the form of "Devil's Canyon", and thus officially ended "tick-tock" as a practice.

This caused it to be woefully uncompetitive in essentially every area outside of raw multi-thread performance and its use in low power APUs with integrated Radeon graphics.

[10] Despite a die shrink and several revisions of the Bulldozer architecture, performance and power efficiency failed to catch up with Intel's competing products.

[11] Consequently, all of this forced AMD to completely abandon the entire high-end CPU market (including desktop, laptops, and server/enterprise) until Ryzen's release in 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 central processing unit (CPU) market, offering a product range capable of competing with Intel.

[14] The Zen architecture delivers more than +52 percent improvement in instructions per cycle (clock) over the prior-generation Bulldozer AMD core, without raising electrical power use.

The 1000 series featured up to eight cores and sixteen threads, with a +52 percent instructions per cycle (IPC) increase over their prior CPU products, namely AMD's previous Excavator microarchitecture.

[19] The third generation of Ryzen processors launched on July 7, 2019, based on AMD's Zen 2 architecture, featuring significant design improvements with a +15 percent average IPC boost, a doubling of floating point capability to a full 256-bit-wide execution data path much like Intel's Haswell released in 2014,[20] a shift to an multi-chip module (MCM) style "chiplet" package design, and a further shrink to Taiwan Semiconductor Manufacturing Company (TSMC)'s 7 nm fabrication process.

[22] This was followed by an unusually short stop-gap release of Ryzen 6000 mobile-only series processors on January 4, 2022, using the modestly changed Zen 3+ core on a 6 nm process by TSMC, with claims up to +15 percent performance uplift gains from frequency rather than IPC.

Jim Keller, leading the new RISC-V team at Tenstorrent, claims absolute dominance in integer performance in a specific INTSPEC benchmark slide which was taken down.

[citation needed] Threadripper, which is geared for high-end desktops (HEDT) and professional workstations, was not developed as part of a business plan or a specific roadmap.

[27] Introduced on the Ryzen 7040 mobile series in mid 2023, it can be used to run neural network applications such as camera background effects, voice recognition, photo artifact removal and skin smoothing.

[28] Neural network tasks can be computationally intensive to run on a general-purpose CPU, resulting in significant energy usage and a larger thermal footprint.

In January 2018, AMD announced the first two Ryzen desktop APUs with integrated Radeon Vega graphics under the Raven Ridge codename.

[46] In February 2018 AMD announced the V1000 series of embedded Zen+ Vega APUs, based on the Great Horned Owl architecture, with four SKUs.

Desktop and mobile APUs are based on the Picasso microarchitecture, a 12 nm refresh of Raven Ridge, offering a modest (6 percent) increase in clock speeds (up to an additional 300 MHz maximum boost), Precision Boost 2, an up-to-3-percent 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.

[53] Fabricated at GlobalFoundries, this gives Picasso an aggregate 10 percent performance uplift from the "original" 14 nm Zen-based Raven Ridge series initially released in 2017.

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 (codenamed Raphael).

[89] AMD claims that the integrated graphics in Ryzen 8000G APUs is capable of playing AAA games such as Cyberpunk 2077 and Far Cry 6 at 1080p low settings.

Utilizing the Zen 5 microarchitecture and built on a TSMC 4 nm process, Granite Ridge features up to 16 cores, uses the AM5 socket and has the same up-to-two-CCDs and one I/O die chiplet layout as the direct predecessor line of CPUs, Raphael.

[94] Ryzen 9000 processors were originally scheduled to launch at the end of July 2024, but had been delayed to early August for quality control reasons.

It features up to 12 cores, a third-generation Ryzen AI NPU based on XDNA 2 and up to 16 compute units (CUs) of RDNA 3.5 integrated graphics.

[102] AMD has allegedly decided not to introduce a whole range of SKUs that previously existed, namely U (ultra-low power) and H(S) (high performance) models and instead OEMs are now allowed to configure the APU thermals as they see fit ranging from 15 to 54 W.[citation needed] The codename "Krackan Point" and high-end codename "Strix Halo" additions to the 300 series were announced on January 6, 2025 at CES 2025.

IPC uplift was eventually gauged to be 52 percent 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.

[111] 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.

[112] Subsequent updates to Ashes of the Singularity: Escalation and Rise of the Tomb Raider increased frame rates by 17-31 percent on Ryzen systems.

However, newer hardware including AMD Ryzen and Intel Kaby Lake and later is only officially supported by Microsoft with the use of Windows 10.

[135] In early 2018, Israeli computer security consultancy firm CTS Labs stated that they had discovered several major flaws in the Ryzen components ecosystem,[136] publicly disclosing them after giving AMD 24 hours to respond and raising concerns and questions regarding their legitimacy,[137][138] though they were later confirmed by two separate security firms.
