AMD has released a whole range of Ryzen chips for desktops this year. Based on the company’s new Zen architecture, the processors offer a big performance boost over previous-generation AMD chips, while also offering energy efficiency improvements.

The chip maker is also expected to launch its first Ryzen chips for laptops by the end of the year, but the company hasn’t made any official statements about the pricing or release date yet… or even what the new chips will be called.

But tanks to some recent leaks, we already know that one of the first Ryzen mobile chips will be the Ryzen 5 2500U. And now the folks at HP have posted a product datasheet for an unannounced laptop powered by that processor, suggesting a launch is imminent.

The HP Envy x360 15-bq101na is a convertible notebook with a 15.6 inch, full HD touchscreen display with edge-toedge glass and support for pen input.

It also seems to be one of the first laptops that will ship with a Ryzen 5 2500U processor, which is described as a quad-core chip with a 2 GHz base frequency and burst speeds up to 3.6 GHz. It has 6MB cache.

Unlike AMD’s Ryzen chips for desktops, the Ryzen Mobile chip also features integrated graphics, with a GPU based on AMD”s Radeon Vega Mobile architecture.

While it’s always a good idea to take PC manufacturers’ battery life estimates with a grain of salt, HP says this notebook should get up to 10 hours and 15 minutes of run time from its 55..8 Wh battery, suggesting the Ryzen 5 2500U chip is roughly comparable to an Intel Core i3/i5/i7 processor in terms of power consumption.

The notebook’s other features include 8GB of DDR4-2400 RAM and a 256GB NVMe solid state disk, so it seems safe to assume AMD’s new chips will support those features.

There are no details about the price or launch date for the laptop, but I suspect it’ll hit the streets around the same time that Ryzen Mobile chips are publicly launched.

  1. As It may be only one CCX I wonder if the memory will be single channel or if the GPU will provide a second channel

  2. “include 8GB of DDR4-2400 RAM and a 256GB NVMe solid state disk, so it seems safe to assume AMD’s new chips will support those features”

    LOL. Have you ever seen a chip without RAM or HD support ?

    1. You do know that some CPU’s don’t support high-frequency RAM right?
      Some don’t even support DDR4.
      Not to mention some only have a SATA connection, or an M.2 (w/o NVMe).

      Although most of these are attributed to the motherboard, its not exclusively the case.
      So in that sentence, Brad really didn’t waste his breath. Or word count.

      1. Yeah, I guess the “interesting” part is that it supports 8GB of DDR4-2400. Many Intel Atom chips topped out at 4GB or less and didn’t support that frequency, for instance… although most recent Celeron and Pentium chips support at least 8GB.

        It would have been surprising if Ryzen Mobile didn’t, since it seems to be targeting Core i rather than Celeron/Pentium.

  3. I always take the manufactures battery life ratings and cut them in half. So 10 hours and 15 minutes would translate into 5 hours of actual battery life. That’s still better than most Dell laptops.

    1. It will always depend on your actual usage.

      I have an HP Spectre x360 13″ (Kaby Lake), and it lasts ~8-9hrs on non-heavy usage.

      However, tests on the laptop show a huge divergence (2hrs to 9hrs to *20*hrs:, and I bet the Kaby Lake-R versions will have even more, given it’s even further optimised for battery life in low usage situations.

      As for Rylen… we shall see how it performs?

  4. Until AMD equipped laptops have thunderbolt 3 I will be reluctant to join. Already got a fair amount of kit that requires it. Unfortunately this probably locks me to Intel even after the opening up of the TB3 standard.

    1. Not many people use Thunderbolt; It’s about where FireWire used to be.
      I think it’s most likely Thunderbolt will die off as a standard, because USB 3.x can already give people the bandwidth 99% of devices will need, and it’s already very widely supported.

      Maybe there will be a few niche cases Thunderbolt will be used; something like external graphics cards maybe, where USB 3.x’s overheads/latency would not be good enough. But outside of that, I don’t think most people will use it.

      1. As you said; eGPU’s.
        The ThunderBolt 3 protocol is limiting as it is at 40Gbps. Were seen bottlenecks for GPUs above a R9290/RX470/GTX980/GTX1060.

        Where something like a Desktop 1080Ti will instead perform like a 1080, and a 1080 like a 1070, and a 1070 slightly above a 1060.

        USB-C 3.1 gen2 is at a much lower bandwidth of 10Gbps. It can’t really do eGPUs practically, you would get far lower performance/more bottlenecks.

        I was hoping USB 3.2 would solve this issue with an increased bandwidth, but it hasn’t. It only tops out at 20Gbps. I was hoping they would strive for 50Gbps, in which case, I would say ditch Intel from Laptops and go for AMD.

        However as it stands, Intel still has a feature advantage over AMD and that is USB-C Thunderbolt3. I believe eGPU’s will find it’s market as these things converge: Expansion of PC Gaming, Decrease price of GPUs (minors), Increased Laptop performance, and increased adoption of a high bandwidth connection.

      2. That’s the thing, you look at USB devices and it’s all evolutions of USB 1 and 2 devices. A flash drive that can read and write faster, a mouse that gains nothing from the faster interface. Thunderbolt 3 devices are fundamentally different. For a simple example of that, plug two thunderbolt laptops together. Bam, 10gig network between them. That is not possible on USB without USB to 10gig ethernet adapters (which AFAIK don’t exist) because USB is host to device and never host to host. You can get a long way with that but you need workarounds, like if my chromecast wants to talk to my receiver to display the name of the currently playing TV show, it can’t use HDMI CEC. It can’t use USB. Atm it’d have to use ethernet over HDMI or send data over WiFi and back. No. Just treat the chromecast as a host and have a conversation with it over TB3. Send your video data over that link too why not.

        1. I think I forgot to get to the point. In the chromecast and receiver example, what’s the host? It’s the receiver right? It’s a bigger box, has more smarts, does more stuff, it even provides power to the CC. It’s not the host though since the CC ignores the data lines on the incoming USB connection (it’s just a charger right?) and then treats everything downstream of HDMI as the client.

          In reality the two devices are hosts but they’ve only got host to client connections to communicate over and this makes getting a message from one to the other and back harder than it should be. It’s better to assume everything is a host. Ethernet does that and has been dominant for 25 years.

  5. To clarify, the 45W power adapter is for supplying the device’s total power requirements, including those of the display and those of an adequately quick charging system, and not just those of the CPU. That means that for that 45W rating for the power adapter, based on other previous notebooks, we should expect a CPU TDP of around 15-25W. For example, many of HP’s laptops with the Core i7-7200U, a 15W processor with an optional 25W cTDP Up configuration, have a 65W power adapter.

  6. This might suggest 4MB L3$ only and the other 2MB are L2$ (512KB per core) as opposed to having 8MB L3$ and disabling 2MB with this SKU.
    Would seem like a weird choice but maybe less so if the power and area savings go towards the GPU since that’s what makes their offering much better than Intel’s.

    1. Desktop Ryzen chips have two 4-core CCX’s, each of which have 4MB L3 cache, for a combined total of 8MB L3 cache.
      Raven Ridge has one 4-core CCX with 4MB L3 cache.
