First AMD Ryzen Mobile Laptop Tested Shows Strong Zen-Vega Performance (hothardware.com)

MojoKid writes: AMD Ryzen Mobile processors are arriving now in retail laptops from the likes of HP, Lenovo and Acer. With the first CPUs to hit the market, AMD took quad-core Ryzen and coupled it with 8 or 10-core Vega GPUs on a single piece of silicon in an effort to deliver a combination of strong Ryzen CPU performance along with significantly better integrated graphics performance over Intel's current 8th Gen Kaby Lake laptop chips. AMD Ryzen 7 2700U and Ryzen 5 2500U chips have 4MB of shared L3 cache each, but differ with respect to top-end CPU boost clock speeds, number of integrated Radeon Vega Compute Units (CUs), and the GPU's top-end clocks. Ryzen 7 2700U is more powerful with 10 Radeon Vega CUs, while Ryzen 5 2500U sports 8. Ryzen 7 2700U also boosts to 3.8GHz, while Ryzen 5 2500U tops out at 3.6GHz. In the benchmarks, Ryzen Mobile looks strong, competing well with Intel quad-core 8th Gen laptop CPUs, while offering north of 60 percent better performance in graphics and gaming. Battery life is still a question mark, however, as some of the very first models to hit the market from HP have inefficient displays and hard drives instead of SSDs. As more premium configurations hit the market in the next few weeks, hopefully we'll get a better picture of Ryzen Mobile battery life in more optimized laptop builds.

    The laptop reviewed (HP Envy x360) is a 15-inch laptop being compared to 13-inch laptops. The screen of the review laptop is turned up 100%, while many of the compared laptops were not. Also, there was no hardware acceleration on the video application used in the Ryzen laptop test. Pretty confident that with a more competent OEM they'd fix the screen issues (screen take up a huge chunk of most mobile devices power), put in a bigger battery and an upcoming update from AMD should make hardware acceleration work on more applications. With that solved this should be easily competitive with Intel mobile CPUs.

    I await Acer and Dell's efforts before I'd write Ryzen Mobile off.
