The performance differences mostly boil down to clock speed. The Ryzen 3 starts with a 2.1GHz base clock speed, a 3.5GHz peak speed and a 6-core Vega GPU. Move to the Ryzen 5 and you'll get a higher 3.7GHz boost speed and an 8-core GPU, while the Ryzen 7 ramps up to a 2.3GHz base speed, a 4GHz boost speed and a 10-core GPU. There's also a dual-core, 2.4GHz (3.3GHz peak) Athlon Pro 300U chip for the cost-conscious with three-core graphics.

Not surprisingly, AMD is claiming a performance edge over Intel. It believes the Ryzen 7 Pro is as much as 14 percent faster for media creation and day-to-day office tasks than a comparable Intel Core i7 laptop. You'll want to take claims like this with a grain of salt, as you do with other manufacturers, but it does bode well you want to wring every ounce out of productivity out of your portable PC.

You won't have to search far to find systems. HP and Lenovo have committed to launching Ryzen Pro-based laptops later in the second quarter (no later than June), and other PC makers are waiting in the wings.
