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."

Last month AMD formally launched its Ryzen Mobile APUs with partners Acer, HP, and Lenovo announcing that systems using the new processors would be out by the end of the year. The first system to become available for purchase appears to be the HP Envy X360 convertible notebook which is available with a Ryzen 5 2500U APU. The 15.6” 2-in-1 starts at $574.99 (at time of writing) and thankfully appears to take full advantage of the AMD processor.

The HP Envy X360 was spotted by Anandtech who noted that the notebook is currently being sold at HP.com as well as brick and mortar Best Buy stores. The notebook is part of the company’s higher end Envy brand. It weighs in at 4.75 pounds and measures 14.16” x 9.8” x 0.77”. The 360° hinge allows the touchscreen display to flip around to lay flat with the underside of the keyboard enabling tablet mode. The top half with thin bezels holds the 15.6” 1920 x 1080 display and IR capable Windows Hello camera. The bottom half holds the rest of the hardware and features a backlit island-style keyboard with numpad, a wide trackpad, and the various I/O ports around the edges including USB-C 3.1 Gen 1 with DisplayPort 1.4 and USB Power support (for charging), two full size USB 3.1 Gen 1 ports, HDMi, and a headset jack. Other features include Bang and Olufsen audio with dual speakers and a stylus that can be used with Windows Ink, One Note, and other apps.

Internal specifications include the above-mentioned Ryzen 5 2500U, up to 16 GB of dual channel 2400 MHz memory, and mechanical and solid-state storage options. The base model of this laptop starts at 8 GB DDR4 at 2400 MHz (2 x 4GB) and 1TB of 7200 RPM hard drive storage. Users can configure the notebook with up to a 1TB NVMe SSD or a combination of SATA hard drive and NVMe M.2 drives. The HP Envy X360 also features Intel 802.11ac Wi-Fi and it is all powered by a 3-cell 55.8 Wh battery. The APU is a 15W TDP chip with four Zen-based CPU cores (eight threads) running at 2 GHz base and up to 3.6 GHz boost, a RX Vega-based GPU clocked at up to 1100 MHz with 8 CUs (512 cores), and 6 MB of cache (2MB L2 and 4MB L3).

The HP Envy X360 15z Touch convertible laptop is available now starting at $574.99 and going up to $1374.99 fully loaded with Windows 10 Pro.

In all this looks to be a good design win for AMD is a promising start for the future of Ryzen Mobile. Thankfully the APU appears to be running at its full 15W TDP and is not being held back by single channel memory like past AMD mobile chips have allegedly been. I am looking forward to seeing what AMD’s other partners have to offer. Until then though, we have a Ryzen 7 1700 powered Asus ROG gaming laptop to ponder about!

AMD Raven Ridge Performance Leaks - APU with GeForce MX150 Performance

Hot on the heels of the HP leak that showed the first AMD Raven Ridge based notebook that may be hitting store shelves later this year, another leak of potential Raven Ridge APU performance is cycling through. The AMD Ryzen 7 2700U with integrated Vega-based graphics architecture, and also rumored to have a ~35-watt TDP, is showing 3DMark11 graphics scores near that of the discrete NVIDIA GeForce MX150.

With a graphics score of 4072, the integrated graphics on the upcoming AMD APU is slightly behind the score of 4570 from the MX150, a difference of 11.5%. Interestingly, the Physics score on the Raven Ridge APU of 6419 is solid as well, and puts an interesting light on the 8th gen KBL-R processors. As you can see in the graph below, from two systems we already have in-house with quad-core parts, CPU performance is going to vary dramatically from one machine to the next depending on the thermal headroom of the physical implementation.

The HP Spectre x360 with the Core i7-8550U and the MX150 GPU is able to generate a Physics score of 8278, well above the leaked result of the Raven Ridge APU. However, when we ran the 3DMark11 on the ASUS Zenbook 3 UX490UA with the same Core i7-8550U, the Physics score was 6627, a 19% drop! Clearly there are configurability shifts that will adjust the performance of the 8th gen Intel parts. We are diving more into this effect in a couple of upcoming reviews.

Though the true power consumption of these Ryzen 7 2700U systems is still up in the air, AMD has claimed for some time that it would have the ability to compete with Intel for the first time in several generations. If these solutions turn out to be in the 35-watt range, which would be at or lower than the typical 15-watt Intel CPU and 25-watt NVIDIA discrete GPU combined, AMD may have a winning combination for mobile performance users to entertain.

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.)

Raven Ridge rumours

If the rumours are true, the new 14nm Raven Ridge based AMD Ryzen 5 2500U will offer an impressive jump in performance compared to AMD's current generation of APUs.  The Inquirer's source suggests the new APU will offer a 50% jump in single threaded performance and an impressive 90% advantage on multi-threaded performance.  The multithreaded performance improvement may be the headline but seeing a huge increase in single threaded applications, AMD's recent Achilles Heel, shows some interesting improvements to Zen.  This will also mark the arrival of their first APU with Vega onboard, so you can expect better graphics performance as well.  The benchmark numbers and links are here.
