Ryzen 4000 review: AMD’s 7nm Ryzen 9 offers game-changing performance for laptops

When AMD introduced its Ryzen 4000 mobile CPUs at CES, the company made bold claims of game-changing performance. Coming off of years of underwhelming laptop chips, AMD promised it had optimized Ryzen 4000 for mobile computing.

Now we’ve tested those claims in AMD’s Ryzen 9 4900HS chip, an 8-core, 7nm chip with Radeon Vega cores. We’re stunned at the CPU’s impressive tour de force that defeats just about every Intel 8th- and 9th-gen laptop CPU we’ve ever seen.

Just open up your YouTube feed and you’ll see pretty much every PC hardware channel staring at disbelief in just how good AMD’s Ryzen 4000 mobile processors really are. This isn’t just a “kind of good enough” processor – the top of the line model is faster than or equal than Intel’s top of the line processor at both single core and multicore workloads, while using slightly more than half the power.

It’s all well and good for AMD to roundly run circles around Intel in the server and desktop/workstation space, but the laptop space is where the real money and mindshare can be found. This new line of AMD mobile processors is simply stunning.
