AMD's Ryzen 4000 mobile CPUs are making their way into some attractive laptops, but which is the right option for you?
Revealed in the first quarter of 2020, AMD's Ryzen 4000 mobile lineup of processors (CPU) has found its way into a bunch of our picks for the best Windows laptops. Split into U-series and H-series chips, the former is intended for slim Ultrabooks, while the latter is intended for high-performance gaming and design laptops. There are a lot of different numbers at play here, and it can be confusing when you're shopping for a new laptop that houses one of these CPUs. Let's take a look at what you need to know when picking an AMD Ryzen 4000 mobile CPU.
AMD Ryzen 4000 U-series mobile CPUs
Just like Intel does with its mobile CPUs, AMD splits its U-series chips into three major categories based on performance. Ryzen 3 is comparable to the Core i3, Ryzen 5 to the Core i5, and Ryzen 7 to the Core i7.
- Ryzen 3 — Up to 4 cores and 8 threads
- Ryzen 5 — Up to 6 cores and 12 threads
- Ryzen 7 — Up to 8 cores and 16 threads
These AMD Ryzen 4000 U-series CPUs are built with a 7nm process and have 15W thermal design power (TDP). Ryzen 3 is reserved for entry-level laptops, Ryzen 5 is best for mid-range laptops, and Ryzen 7 is for premium Ultrabooks that deliver top-shelf performance. These CPUs are not available to purchase individually; if you want to invest in one, you'll have to choose a laptop that employs it. If you are looking for a similar rundown of AMD's desktop CPUs, have a look at our guide to choosing the right desktop Ryzen chip.
AMD Ryzen 3 4000 U-series CPUs
The U-series Ryzen 3 is available in one basic version with a PRO option riding alongside. Budget laptops like Lenovo's IdeaPad Flex 5 14, HP's ENVY x360 13, and the Acer Swift 3 are often configurable with the Ryzen 3 4300U, while the Ryzen 3 PRO 4450U is meant for business laptops like HP's EliteBook line and Lenovo's ThinkPad line. Both options have four cores and integrated Vega graphics with five cores.
The PRO version of the U-series Ryzen 3 is meant for workforces that need extra security, multi-threading, and manageability. For most consumers this chip isn't going to be an option, but it's worth mentioning that it's out there. Here's how the standard Ryzen 3 4300U compares to the Ryzen 3 PRO 4450U.
| CPU | Cores | Threads | Base/Boost clock | Cache | GPU | TDP |

Bottom line: The Ryzen 3 U-series mobile CPU is best reserved for productivity work, including word processing, web browsing, video streaming, and messaging apps. It will handle a relatively robust load, but don't expect it to measure up to Ryzen 5 and Ryzen 7 chips. Heavy multitasking will bog it down.
AMD Ryzen 5 4000 U-series CPUs
The Ryzen 5 U-series has three entries, with a standard six-core, six-thread option, a six-core option with 12 threads, and a PRO version with six cores, 12 threads, and the same security and management perks typical for the workforce focus. All options have a 15W TDP that sips power, and all options have six GPU cores for their Vega integrated graphics.
If you're interested in heavier multitasking, the Ryzen 5 4600U's multithreading ability should be attractive, though these CPUs seem to be harder to find than the standard 4500U. Let's take a look at how the three Ryzen 5 4000 U-series CPUs compare.
| CPU | Cores | Threads | Base/Boost clock | Cache | GPU | TDP |
|---|---|---|---|---|---|---|
| Ryzen 5 4500U | 6 | 6 | 2.3GHz (4.0GHz) | 11MB | Vega 6 | 15W |
| Ryzen 5 4600U | 6 | 12 | 2.1GHz (4.0GHz) | 11MB | Vega 6 | 15W |
