It’s been a long time coming but information has finally leaked on AMD’s first Ryzen Mobile chips for laptops. The leak in question is for Ryzen 5 Pro Mobile, AMD’s first Zen-based APU that will also include onboard Radeon Vega graphics.

A leaked performance slide suggests that AMD has got Intel Kaby Lake i5 CPUs absolutely smashed in terms of performance while matching its idle power draw. It is worth mentioning though that there is no scaling present for any of these charts, so take them for what they're worth.

Whatever the case, it seems a dead cert that AMD will gazump its own Bristol A12 APU in terms of performance. The A12-9800 Bristol Ridge release just a few months ago but it was still manufactured on the ageing 28nm fabrication process, compared to 14nm for first-gen Ryzen.

AMD will be more interested in beating Intel’s equivalent Kaby Lake chips though, and in these three particular tests it comes out on top every time. It’s the last one for idle power that could ultimately prove the most interesting for AMD. Team Red has long been known for its power-guzzling ways, which doesn’t make for a great mix with mobile devices. Here we see parity with Intel, potentially making AMD a legitimate contender for inclusion in notebooks at long last.

GPU performance may not be all that much improved though considering the switch to Vega. Ryzen 5 Mobile just edges out Bristol A12’s score in a 3DMark 11 benchmark. It’s not the sort of thing you’re going to want to rely on from a gaming point of view, although it should be a fairly capable APU for playing older games on the go.

The mobile sector is a huge deal, and it's a slice of the pie that AMD has been losing out on for years. If they can claw something back with Ryzen then things could get very interesting indeed.

Lastly, a quick shout out to ENTLVL820m for bringing this to my attention.
