AMD Ryzen Names Explained: How to Spot a 2019 Chip in a 2026 Mini PC

This year you can buy a mini PC with a “new” AMD Ryzen 5 3501U, a processor AMD added to its catalog in the second quarter of 2026. On paper, it is the Ryzen 5 3500U from 2019: same cores, same clock speeds, same graphics. It is not an isolated case. AMD gives older chips new numbers almost every year, and the number on the box rarely tells you how old the design inside is. This guide shows how to read a Ryzen name, which digit gives away the real architecture, and where that rule stops working.

The Ryzen 5 3501U: a 2019 chip with a 2026 launch date

AMD’s own product page gives the Ryzen 5 3501U a Q2 2026 launch date, but also the “Picasso” codename, Zen+ cores on a 12 nm process, Vega 8 graphics and DDR4-2400 memory: exactly the recipe of the 2019 Ryzen 5 3500U.

When Bosgame launched its E2 Plus mini PC in August 2026, Notebookcheck compared its processor with the older chip and found “little separating” them: four Zen+ cores with simultaneous multithreading, 2.1 to 3.7 GHz, the same Vega 8 graphics at up to 1.2 GHz, and identical cache, memory support and 15 W default power. In AMD’s catalog, the new name sits in the “Ryzen 3000 Series” next to its 2019 siblings.

Sources: AMD product page, Notebookcheck (Aug 11, 2026), PassMark averages read Oct 21 and Nov 3, 2026. With only 13 results, the 3501U’s PassMark average can still move; the 2% gap is within normal variation.

AMD added a two-core Ryzen 3 3100U to the same Zen+ family at the same time (Wccftech), and the 3501U quickly found its way into budget mini PCs: the Bosgame E2 Plus (8GB of DDR4 and a 256GB SATA SSD in its base version), the Bosgame E2 Air, a Getorli model, and a GMKtec NucBox G10 Plus spotted on Geekbench. A few weeks later, Bosgame’s E5 Plus brought back the Ryzen 3 5400U, a Zen 3 chip from 2021.

Is the 3501U a bad chip? Not for light work. In PassMark it averages 6,606 points in multi-core, about 24% more than an Intel N150 (5,334), and the two are level in single-thread (1,859 vs 1,890), the score that decides how quickly Windows and a browser respond. AMD lists official Windows 11 support. The catch is that it does this at 15 W instead of the N150’s 6 W, with DDR4-2400 memory and PCIe 3.0, and a Ryzen 7 7735HS scores more than three times as much in multi-core. A 3501U box is only a good deal when it costs about as little as an N150 box. Our N150 vs N100 vs N97 comparison covers the Intel side of that budget.

How to read a Ryzen laptop chip name (2023 to 2025 models)

Since 2023, AMD’s mobile model numbers follow a four-digit “decoder ring”: model year, market segment, CPU architecture, then a minor tier, followed by a power suffix. The third digit is the one that reveals the architecture.

AMD announced the scheme in September 2022 for every laptop chip from 2023 on, and mini PC makers use the same laptop chips. Here is how a Ryzen 5 7640HS breaks down:

AMD’s 2023+ mobile decoder, as published by AMD and AnandTech in September 2022.

• First digit, model year: 7 for 2023, 8 for 2024, 9 for 2025. It says when AMD started selling that model, nothing more.
• Second digit, segment: 1 and 2 are Athlon, 3 and 4 Ryzen 3, 5 and 6 Ryzen 5, 7 Ryzen 7, 8 Ryzen 7 or 9, 9 Ryzen 9.
• Third digit, architecture: 1 = Zen or Zen+, 2 = Zen 2, 3 = Zen 3, 4 = Zen 4, 5 = Zen 5. A model ending in 35, such as the 7735HS, is Zen 3+.
• Fourth digit: 0 for the lower model, 5 for the higher one in the same segment.
• Suffix: U chips target 15 to 28 W, HS around 35 W and HX 55 W and more; plain H models (45 W class), such as the Ryzen 7 8745H, also exist. Mini PC makers often set their own power limits, which is why the same chip can score differently from one box to another (see the reality check in our mini PC processor ranking).

The trap: the first digit is the year of sale, not of design

A “7” means “sold from 2023”, not “Zen 4 from 2023”. The Ryzen 7000 laptop family mixed Zen 2, Zen 3, Zen 3+ and Zen 4 designs, and AnandTech wrote at the time that the year digit ends up “essentially being worthless for determining the architecture”.

AMD was open about the reason: laptop makers want models with a current year number, and AMD does not redesign its whole range every year. AnandTech summed it up as OEMs wanting parts with “current” model year numbers. XDA warned that the scheme would make it “a bit harder to tell” when a new chip uses an older architecture, and that is exactly what happened.

The gap is not academic. The Ryzen 5 7520U and Ryzen 5 7530U differ by one digit, yet PassMark’s averages put the Zen 3 7530U about 67% ahead in multi-core (14,854 vs 8,905). The 7520U is the chip in many of the cheapest Ryzen laptops and mini PCs, and since October 2025 the same chip is also sold as the Ryzen 5 40, which Notebookcheck says does not differ from the 7520U.

Before 2023, the same problem without a decoder

The older names have no architecture digit at all. The Ryzen 5000 laptop family mixed two designs: the Ryzen 5 5600U and Ryzen 7 5800U use Zen 3 (Cezanne), while the Ryzen 5 5500U and Ryzen 7 5700U use Zen 2 (Lucienne), which Notebookcheck describes as “a generation older than their names suggest”. Mini PCs still sell both: the Beelink SER5 uses a Zen 2 Ryzen 5 5500U, the GMKtec M5 Plus a Zen 3 Ryzen 7 5825U, and Bosgame moved its E5 from a Zen 2 Ryzen 3 5300U to a Zen 3 Ryzen 3 5400U in the E5 Plus. For these names, the codename is the only reliable clue: Picasso = Zen+, Renoir and Lucienne = Zen 2, Cezanne and Barcelo = Zen 3.

Ryzen 100 and 200: the newest names hide older chips

From 2025, AMD moved existing chips to three-digit names with no architecture digit. The Ryzen 200 series is Zen 4 “Hawk Point”, the same silicon as the Ryzen 8040 chips, and the Ryzen 100 series now holds both Zen 3+ and Zen 4 chips.

• Ryzen 200 (2025): Hawk Point, Zen 4 with Radeon 700M graphics. Notebookcheck’s first benchmarks found the Ryzen 7 H 255 (a China-only model) to be a rebadged Ryzen 7 8845HS, and describes the Ryzen 7 255 as the same chip as the older Ryzen 7 8745H, with no NPU installed or activated. AMD added a Ryzen 7 253 and 249 in 2026. You will find these in the Reatan X7 (Ryzen 7 255) and the Beelink SER9 Pro (Ryzen 7 H 255).
• Ryzen 100 (October 2025): the Zen 3+ Ryzen 7035 chips got new names. The Ryzen 7 170 is the Ryzen 7 7735HS, the 160 is the 7735U, the 150 the 7535HS, the 130 the 7535U and the 110 the 7335U; the Zen 2 Athlon Silver 7120U became the Athlon Silver 10 (KitGuru). Notebookcheck says the Ryzen 7 170 is “identical to the old Ryzen 7 7735HS from 2023”.
• Ryzen 100, part two (June 2026): four more models, the Ryzen 9 180, Ryzen 7 165, Ryzen 7 155 and Ryzen 5 125, joined the same series, but Guru3D reported them as rebranded Zen 4 Hawk Point chips, and Notebookcheck’s spec pages list them at 4 nm with RDNA 3 graphics. At the time, AMD’s own product pages listed them as “Zen 3+” next to the Hawk Point codename (Igor’s Lab). Notebookcheck lists the Ryzen 7 155 with six cores, Radeon 740M graphics and a disabled NPU.

None of this makes these chips bad buys. A Zen 3+ Ryzen 7 7735HS still has eight cores, 16 threads and Radeon 680M graphics, and PassMark averages 22,120 points for it, more than three times the 3501U. It is a sound choice when it is priced as a 2022 design.

Ryzen AI: a different scheme, and what the series number means

Ryzen AI names, such as Ryzen AI 9 HX 370, dropped the year and architecture digits. The first digit of the number is the series: 300 is the 2024 to 2025 Zen 5 generation, 400 is its 2026 refresh with the same architecture, and Ryzen AI Max is the much larger Strix Halo chip.

The Ryzen AI scheme introduced at Computex 2024.

• Ryzen AI 300: Zen 5 and compact Zen 5c cores, RDNA 3.5 graphics and an XDNA 2 NPU. AMD jumped straight to “300” because these chips carry its third-generation NPU (Notebookcheck). The big chips (HX 370, Strix Point) are in boxes like the Peladn HO5; the smaller Ryzen AI 5 340 and Ryzen AI 7 350 (Krackan Point) appear in designs like the HP EliteBoard G1a.
• Ryzen AI 400 (2026): codenamed Gorgon Point, a refresh with the same Zen 5, RDNA 3.5 and XDNA 2 building blocks (Wccftech), higher clocks and faster memory support. Notebookcheck measured the Ryzen AI 9 HX 470 only about 7% ahead of the average HX 370.
• Ryzen AI Max: Strix Halo, with 16 Zen 5 cores and a 40-unit Radeon 8060S. Same brand, very different class: see our Strix Halo explainer.

Within Ryzen AI, the architecture is at least consistent: every Ryzen AI 300 and 400 chip uses Zen 5. What the “AI” really buys you is an NPU of 50 TOPS or more, above the 40 TOPS Microsoft requires for Copilot+ features. Local chatbots mostly run on the graphics and memory instead, as we explain in what an NPU really does.

Every Ryzen chip you’ll find in a mini PC: name, real architecture, year

The table matches the names on current mini PC listings with the silicon inside. When “silicon first sold” is years older than “name launched”, you are looking at a renamed or refreshed design.

Shaded rows: names launched at least a year after the silicon first shipped. “Silicon first sold” is the year the same die first appeared in a product under any name. Sources: AMD product pages, Notebookcheck, KitGuru, Guru3D. “Seen in” lists examples from reviews and listings, not every model.

What the gap means in practice: PassMark scores

In PassMark’s CPU Mark, chips sold under 2023 names span more than three times in multi-core performance, from about 8,900 points for the Zen 2 Ryzen 5 7520U to 28,200 for the Zen 4 Ryzen 7 7840HS.

PassMark averages read between Oct 21 and Nov 3, 2026. They mix laptops and mini PCs running at different power limits, and HS chips score higher partly because they are allowed more power. The Ryzen 5 3501U average rests on only 13 results.

Single-thread scores are the most telling for everyday speed: a Zen 4 Ryzen 7 7840HS scores about twice as much as a Zen+ 3501U (3,699 vs 1,859), and that is the difference you feel when opening apps or busy web pages. For Zen 4 and Zen 5 chips measured in Cinebench, see our best mini PC processor guide.

How to check any Ryzen listing in two minutes

Copy the exact processor name from the listing, look it up on AMD’s product page and on Notebookcheck, and compare the codename with the name. If the codename is older than the name suggests, judge the PC by the old chip’s benchmarks and price.

1. Find the full model name, such as “Ryzen 5 3501U”, not just “Ryzen 5” or “up to 3.7 GHz”. A listing that hides the model is a warning sign in itself.
2. Open AMD’s product page for that model and read “Former Codename” and “Processor Technology”. Don’t rely on the launch date: AMD lists Q2 2026 for the 2019-designed 3501U.
3. Check Notebookcheck’s page for the codename, the series it belongs to (for example “Picasso (Ryzen 3000 APU)”) and benchmark averages.
4. Compare on PassMark with a chip you know: an Intel N150 for budget boxes, a Ryzen 7 7735HS or 8845HS for mid-range ones. Look at the number of samples before trusting a new chip’s score.
5. Read the listing itself: make sure the photos, reviews and Q&A mention the same processor, since listings are sometimes reused for a different machine.
6. After delivery, check the processor name in Windows (Settings, System, About) or with the free CPU-Z tool, which also shows the codename. Do it within the return window: our warranty and return policies by brand lists the deadlines.

Which older Ryzen chips are still worth buying

Old is not automatically bad: what matters is the price for the performance. A Zen 3+ Ryzen 7 7735HS (or Ryzen 7 170) still offers eight cores and Radeon 680M graphics, while a Zen+ or Mendocino chip only makes sense when the box costs about as little as an Intel N150 machine.

• Good buys at the right price: Ryzen 7 7735HS / 170 (Zen 3+, Radeon 680M), Ryzen 7 5825U (eight Zen 3 cores), Ryzen 5 7640HS (Zen 4, Radeon 760M), Ryzen 7 8745HS / 255 (Zen 4, Radeon 780M).
• Only if priced like an N150 box: Ryzen 5 3501U, 3500U and 3550H (Zen+), Ryzen 5 7520U and Ryzen 5 40 (Zen 2, two graphics units), Ryzen 3 4300U and 5300U.
• If you want Copilot+ features: only Ryzen AI chips qualify, since Copilot+ needs a 40 TOPS NPU.
