Ryzen 5000 vs. 4000 vs. 3000: Which CPU is better for your laptop?

Which Ryzen-based laptop CPU is the best? Here's what our tests show.

With AMD Ryzen laptops so popular these days, shoppers will likely find Ryzen 4000U- and even a few Ryzen 3000U-based laptops still for sale—and easier to get ahold of than hot-selling Ryzen 5000U-based models.

We’ve delved into the details of the two most recent chip families in our Ryzen 7 5800U review and Ryzen 7 4800U review. But if you’re trying to decide between newer and older Ryzen laptops, we go over the primary differences below to help you decide.

Here are the CPU performance areas we’ll be looking at:

  • Multi-threaded performance is how fast the CPU is at processing multi-core enabled applications such as video editing and encoding, 3D modelling and other heavy-duty advanced applications.
  • Single-threaded performance is more in the realm of Microsoft Office (Although Excel does use more cores), most browsing and even many photo-editing tasks.
  • Gaming performance is the expression of the graphics performance (mostly) of the chip.
  • Battery performance is obvious. While all four performance aspects can be shifted based on each laptop’s design, battery performance is an area where the laptop’s design will have the most everyday impact.

AMD’s Ryzen 5000U series offers fantastic multi-core performance and fantastic single-core performance too.

Multi-threaded performance: Ryzen 5000U

Ryzen 5000U’s performance improvement over Ryzen 4000U is decent, though not as spectacular as the original Ryzen 4000U’s mind-blowing launch. Despite the newer Zen 3 cores, it’s still 8-core vs. 8-core for the Ryzen 7 parts.

If you’re chasing multi-core performance, Ryzen 5000U is preferred, but Ryzen 4000U isn’t a bad second choice. It still crushes Intel’s best 11th-gen U-class CPUs, and it makes the older Ryzen 3000U chip look even worse.

Single-threaded performance: Ryzen 5000U

Ryzen 5000U’s biggest improvement comes in single-threaded and lightly-threaded tasks—which is what most people run on a thin-and-light laptop. While Ryzen 5000U can compete with and sometimes surpass Intel’s best CPUs, this area remains the biggest weakness of Ryzen 4000U. 

If you want improved single-threaded and lightly-threaded performance in such things as Office and web browsing, the Ryzen 5000U is the better chip.

Gaming performance: A tie

Graphics performance of the Ryzen 5000U has improved a little over Ryzen 4000. Both chips will yield very decent gaming performance—although in some games, not quite on a par with Intel’s best.

Battery performance: Hard to call

The Ryzen 4000U is based on a 7nm process and simply blew people away with its multi-core performance.

Battery performance is heavily dependent on how big of a battery the laptop maker installed, the quality of the panel, and many other variables. It’s hard to call a clear winner here as a result.

Both Ryzen 4000 and Ryzen 5000 actually offer competitive battery life compared to each other—as well as to Intel’s CPUs. However, you should read about how Ryzen 5000 juggles performance and battery life to understand how AMD decided to set priorities with the new generation.

Ryzen 3000U: Manage your expectations

We originally didn’t intend to talk about Ryzen 3000U, but we actually found some models for sale. Going back two generations in Ryzen, not surprisingly you’re going to see more weaknesses, so consider carefully before buying.

Multi-threaded performance: While the Ryzen 4000U and Ryzen 5000U offer up to 8-core performance on the advanced 7nm manufacturing process, the older Ryzen 3000U is based on a 12nm process that offered up to 4 cores on the Ryzen 7. It couldn’t compete against Intel’s 10th-gen Ice Lake chips, which also featured 4 cores on an advanced 10nm process. Going up against a Ryzen 4000U or a Ryzen 5000U is no contest.

Single-threaded performance: Single-threaded performance is an even worse loss for the Ryzen 3000U. Intel’s 10th-gen chip easily overmatches it by a healthy double-digit margin, so guess what: Ryzen 4000U and especially Ryzen 5000U stomp the older Ryzen 3000 as well.

The Ryzen 7 3780U inside the Surface Laptop wasn’t really about the CPU—it was more about what was to come from AMD.

To be fair, unlike multi-threaded performance, where you will  see and feel a significant difference, the Ryzen 3000U on single-threaded performance loses handily but is far from a total turkey. It’s just not competitive with its siblings in any possible way.

Gaming performance: Graphics performance on the Ryzen 3000 was its bright spot. For someone looking for a low-budget machine with some semblance of gaming (albeit very scaled back), it’s certainly better than laptops with Intel’s UHD graphics. But against the Ryzen 4000U and the Ryzen 5000U, it’s definitely in a solid third place.

Battery performance: As we’ve been saying, battery life depends on the laptop wrapped around it. The best demonstration of Ryzen 3000U’s biggest weakness you can read our showdown between two Microsoft Surface Laptops which were basically identical, except in CPU: Intel’s 10th-gen Ice Lake, or a custom Ryzen 7 3780U. Microsoft laptops typically use premium parts and offer few compromises. Nevertheless, the Ryzen 3000U lost, and we suspect it would also lose to a Ryzen 4000U and Ryzen 5000U chip as well.

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

MSI GT76

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

MSI PS63

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
