The Tech Report have been spending quite a bit of time with the Ryzen powered HP Envy x360, contrasting its performance to Intel based laptops.  They have moved from performance to battery life, something which means a great deal to those who travel with laptops or simply want to use the laptop without getting tangled in cords.  Their focus in this look at battery life is the impact of using an external screen only, with the built-in display disabled.  They chose a 2560x1440 display and tested the Envy against a Acer Swift 3 with an Intel i5-8250U to see how long the battery lasts without needing to power the integral display.  The results are quite striking and show a large difference in power efficiency.

"As we've continued testing AMD's Ryzen 5 2500U APU over the past few days, we've been confronted with the problem of comparing battery life across laptops with different screen sizes. Many readers suggested that I should take each machine's internal display out of the picture by hooking them up to external monitors. While I wanted to get real-world battery-life testing out of the way first, I can certainly appreciate the elegance of leveling the playing field that way. Now we have."

Mobile gaming on Ryzen 5

HP released a Ryzen powered laptop recently, the Envy x360, which The Tech Report used to test out the performance of the Ryzen 5 2500U.  The APU sports four cores with a base clock of 2.0GHz, boosting to 3.6GHz and eight GPU CUs with a clock of 1100 MHz.  In order to level the playing field when comparing it to Intel-powered gaming laptops, they installed a Samsung 960 EVO 500GB NVMe which was sadly not installed in the Envy.  The mobile chip's GPU matched a pattern similar to Vega GPUs, offering a bit better performance at lower resolutions but vastly outpacing the performance of Intel's integrated GPU at higher resolutions.  You will still be better off with a mobile GPU playing The Witcher 3 at 1600x900 but the fact that the Ryzen can hit 24fps with decent frame times is very impressive indeed. 

It might even run faster once you remove that certain piece of software recently installed on HP laptops.

"AMD's Ryzen 5 2500U pairs the competitive performance of four Zen CPU cores with eight compute units of Vega graphics power in a notebook-friendly power envelope. We put the Ryzen 5 2500U to the test aboard HP's Envy x360 laptop to see whether the fusion of Zen and Vega results in the best APU yet."

Report: Laptop Powered by AMD Ryzen APU Revealed in HP Datasheet

Details on the first notebook featuring an AMD Ryzen APU were revealed by HP from a data sheet on an upcoming Envy x360 2-in-1 notebook, though the PDF was subsequently pulled and now the page leads to a 404. Thankfully, VideoCardz.com has a screen capture:

In addition to the AMD Ryzen 5 2500U quad-core CPU with integrated Radeon Vega M graphics, the notebook as configured offered just a single 8GB stick of DDR4-2400 - and we all know APU’s like memory bandwidth, so hopefully this will be offered with a dual-channel option (memory “up to 16GB” is offered).

Storage for this Ryzen 5-powered 2-in-1 is listed as a 256 GB PCIe NVMe SSD, and the convertible design offers a 15.6-inch 1920x1080 IPS multi-touch display, premium B&O sound, and of course runs Windows 10.

Naturally, we'll have to wait for some official word from HP on this, as the page and document were apparently put up in error - but not before a few outlets (other than VideoCardz posts include ComputerBase and PC Gamer) released the details from the datasheet. Perhaps that will prompt an announcement? (Here's hoping.)
