Buying a new laptop? How to pick the right AMD Ryzen mobile CPU for you.

Like desktop-class processors, Intel and AMD share a similar model-naming scheme. The two main processor families — Core and Ryzen, respectively — use 3, 5, 7, and 9 to differentiate the CPU tiers. Generally, the lower the number, the less capable the processor usually is. A Ryzen 3 processor won't be able to outpace a Ryzen 7 CPU.

Here's a breakdown of the different AMD Ryzen mobile processor brackets:

  • Ryzen 3 Up to 4-core processors.
  • Ryzen 5 Up to 6-core processors.
  • Ryzen 7 Up to 8-core processors.
  • Ryzen 9 Up to 8-core processors.

Within each bracket, the processors are named by model number — the higher the model number, the more powerful the CPU. For example, a Ryzen 5 4500 is less powerful than a Ryzen 5 4600. Different suffixes follow each model number. Here's what they mean:

  • H: High-performance with a TDP of 35-45W.
  • U: Mid-tier with a TDP of 15-28W.
