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!
A potential game changer?
I thought we were going to be able to make it through the rest of 2017 without seeing AMD launch another family of products. But I was wrong. And that’s a good thing. Today AMD is launching the not-so-cleverly-named Ryzen Processor with Radeon Vega Graphics product line that will bring the new Zen processor architecture and Vega graphics architecture onto a single die for the ultrathin mobile notebook platforms. This is no minor move for them – just as we discussed with the AMD EPYC processor launch, this is a segment that has been utterly dominated by Intel. After all, Intel created the term Ultrabook to target these designs, and though that brand is gone, the thin and light mindset continues to this day.
The claims AMD makes about its Ryzen mobile APU (combination CPU+GPU accelerated processing unit, to use an older AMD term) are not to be made lightly. Right up front in our discussion I was told this is going to be the “world’s fastest for ultrathin” machines. Considering that AMD had previously been unable to even enter those markets with previous products, both due to some technological and business roadblocks, AMD is taking a risk by painting this launch in such a light. Thanks to its ability combine CPU and GPU technology on a single die though, AMD has some flexibility today that simply did not have access to previously.
From the days that AMD first announced the acquisition of ATI graphics, the company has touted the long-term benefits of owning both a high-performance processor and graphics division. By combining the architectures on a single die, they could become greater than the sum of the parts, leveraging new software directions and the oft-discussed HSA (heterogenous systems architecture) that AMD helped create a foundation for. Though the first rounds of APUs were able to hit modest sales, the truth was that AMD’s advantage over Intel’s on the graphics technology front was often overshadowed by the performance and power efficiency advantages that Intel held on the CPU front.
But with the introduction of the first products based on Zen earlier this year, AMD has finally made good on the promises of catching up to Intel in many of the areas where it matters the most. The new from-the-ground-up design resulted in greater than 50% IPC gains, improved area efficiency compared to Intel’s latest Kaby Lake core design, and enormous gains in power efficiency compared to the previous CPU designs. When looking at the new Ryzen-based APU products with Vega built-in, AMD claims that they tower over the 7th generation APUs with up to 200% more CPU performance, 128% more GPU performance, and 58% lower power consumption. Again, these are bold claims, but it gives AMD confidence that it can now target premium designs and form factors with a solution that will meet consumer demands.
AMD is hoping that the release of the Ryzen 7 2700U and Ryzen 5 2500U can finally help turn the tides in the ultrathin notebook market.

The Ryzen 7 2700U will run 200 MHz higher on the base and boost clocks for the CPU and 200 MHz higher on the peak GPU core clock. Though both systems have 4-cores and 8-threads, the GPU on the 2700U will have two additional CUs / compute units.

AMD teased its upcoming Zen-based APUs aimed at mobile devices during its Financial Analyst Day where the company revealed the "Raven Ridge" parts will be aptly known as Ryzen Mobile. The Tech Report managed to acquire a couple slides which confirm some of the broader specifications and reveal how they stack up to AMD's latest Bristol Ridge A-Series APUs – at least as far as AMD's internal testing is concerned (which is to say not independently verified yet so take with a grain of salt).
Ryzen Mobile appears to be the new consumer-facing brand name for what has so far been code named "Raven Ridge". These parts will use a Zen-based CPU, Vega GPU, and integrated chipset. Thanks to the slides, it is now confirmed that the Vega-based graphics processor will be on-die. What has not been confirmed is whether the chipset will be on die or on package and exact specifications on CPU cores counts, GPU Compute Units, cache, memory support, and I/O like PCI-E lanes (you know, all the good stuff! heh). Note that rumors so far point towards Raven Ridge / Ryzen Mobile utilizing a single 4-core (8-thread) CCX, per core L2, 8MB shared L3 cache, and a Vega-based GPU with 1024 cores. HBM2 has also been rumored for awhile but we will have to wait for more leaks and/or an official announcement to know for sure if these Ryzen Mobile parts aimed for the second half of 2017 will have that (hopefully!).
With that said, according to AMD, Ryzen Mobile will offer up to 50% better CPU performance, 40% better GPU performance, and will use up to 50% less power than the previous 7th generation (Excavator-based) A-Series APUs (e.g. FX 9830P and A12-9730P). Those are some pretty bold claims, but still within the realm of possibility. Zen and Vega are both much more efficient architectures and AMD is also benefiting from a smaller process node (TSMC 28nm vs Samsung / GlobalFoundries 14nm FinFET). I do wonder how high the APUs will be able to clock on the CPU side of things with 4 GHz seeming to be the wall for most Zen-based Summit Ridge chips, so most of the CPU performance improvement claims will have to come from architecture changes rather than increases in clockspeeds (the highest clocked A-Series Bristol Ridge ran at up to 3.7 GHz and I would expect Raven Ridge to be around that, maybe the flagship part turbo-ing a bit more). Raven Ridge will benefit from the shared L3 cache and, more importantly, twice as many threads (4 vs 8) and this may be where AMD is primarily getting that 50% more CPU performance number from. On the graphics side of things, it looks like Bristol Ridge with its R7 graphics (GCN 3 (Tonga/Fiji on the Desktop)) had up to 512 cores. Again, taking the rumors into account which say that Raven Ridge will have a 1024 core Vega GPU, this may be where AMD is getting the large performance increase from (the core increase as well as newer architecture). On the other hand, the 40% number could suggest Ryzen Mobile will not have twice the GPU cores. I would guess that 1024 might be possible, but running at lower clocks and that is where the discrepancy is. I will admit I am a bit skeptical about the 1024 (16 CU) number though because that is a huge jump... I guess we will see though!
Further, I am curious if Ryzen Mobile will use HBC (high bandwidth cache) and if HBM2 does turn out to be utilized how that will play into the HBC and whether or not we will finally see the fruits of AMD's HSA labors! I think we will see most systems use DDR4, but certainly some SKUs could use HBM2 and that would definitely open up a lot of performance possibilities on mobile!
There is still a lot that we do not know, but Ryzen Mobile is coming and AMD is making big promises that I hope it delivers on. The company is aiming the new chips at a wide swath of the mobile market from budget laptops and tablets to convertibles and even has their sights set on premium thin and lights. The mobile space is one where AMD has struggled with in getting design wins even when they had good parts for that type of system. They will really need to push and hit Ryzen Mobile out of the park to make inroads into the laptop, tablet, and ultrabook markets!
AMD plans to launch the consumer version of Ryzen Mobile in the second half of this year (presumably with systems featuring the new APUs out in time for the holidays if not for the back to school end of summer rush). The commercial SKUs (which I think refers to the Ryzen equivalent of AMD Pro series APUs.Update: Mobile Ryzen Pro) will follow in the first half of 2018.
What are your thoughts on Ryzen Mobile and the alleged performance and power characteristics? Do you think the rumors are looking more or less correct?
