Zen Cores and Vega

Ryzen 3 Mobile, Plus More Ryzen Mobile Laptops

The most immediate announcement from AMD is two Ryzen 3 Mobile processors designed to fill out the Mobile stack, and the introduction of Ryzen-based APUs for desktop machines.

At the heart of both of these designs is the combination of AMD’s first-generation Zen cores, specifically four cores in a ‘core complex’, connected to Vega-based graphics integrated into the silicon. The two units are connected via AMD’s Infinity Fabric, designed for high-bandwidth and scale, and a feature that permeates through AMD’s recent product portfolio.

Ryzen Mobile

To date, AMD has already announced two products using this configuration. Both of them are for Ryzen Mobile, specifically the Ryzen 7 2700U and Ryzen 5 2500U, which have already been pre-announced in devices such as the HP Envy x2, the Lenovo Ideapad 720S, and the Acer Swift 3. Only the HP Envy x2 has been launched into the market so far (with mixed reviews due to the OEM design, which draws similar criticisms when equipped with Intel CPUs), with the others to see light in Q1 as well as other OEMs like Dell.

The first announcement is regarding adding more Ryzen Mobile processors to the family to cater for a wider audience. To pair with the Ryzen 7 Mobile and Ryzen 5 Mobile, AMD has two Ryzen 3 Mobile parts which will formally be available on January 9th with expected system availability within Q1.

The Ryzen 3 2300U is a quad-core processor without simultaneous multithreading, which separates it from the other components. The base frequency of 2.0 GHz, a top turbo of 3.4 GHz, and a total of six compute units in the Vega graphics (this equates to 384 streaming processors). The Ryzen 3 2300U shares the same TDP as the other parts, coming in at 15W, and AMD wants to position this as a high-performance part for eSports capable notebooks, handily beating anything from Intel’s 7th Generation family.

The Ryzen 3 2200U is the only dual core component in AMD’s entire Ryzen product line, although it does have simultaneous multithreading to give it four threads in total. Having two fewer cores to fire up does give it a boost on the base frequency, coming in at 2.5 GHz, but the turbo frequency matches the other Ryzen 3 at 3.4 GHz. The 2200U is certainly the processor bringing up the rear, with only three compute units (192 streaming processors) in total, and helping AMD shift some of the processors that are not binned as aggressively as the higher-performance units.

AMD is promoting these two processors as capable elements of an entry level 15W notebook that can process DirectX 12, offer advanced video features, and be used in aesthetically pleasing designs with a long battery life, including 2-in-1s, ultrathin notebooks, and gaming laptops.

New Devices

Not to be content with just announcing a couple of new Ryzen Mobile processors, AMD was eager to promote new mobile devices that will be using Ryzen Mobile. To accompany the HP Envy x360, the Lenovo Ideapad 720S, and the Acer Swift 3, Q1 will see the launch of a new HP (under embargo until later this week), the Acer Nitro 5 series, and the Dell Inspiron 5000 series.

Acer’s Nitro line of laptops is typically aimed at the gaming crowd. The Nitro 5 dictates a 15.6-inch display, which in this case is a 1920x1080 IPS panel. Acer will use the pre-announced higher-end APUs, the Ryzen 7 2700U and Ryzen 5 2500U, but will also be pairing this with a Radeon RX 560 graphics chip. We were told by AMD that the integrated graphics and discrete graphics will be used in a switching context: for video playback, the lower power integrated graphics is used and the discrete is disabled, however the discrete graphics is fired up for gaming work. For compute, or for games that support multi-adaptor DirectX 12 technologies, both the integrated graphics and the discrete graphics should be available, however this is up to the game/software to implement.

The Dell Inspiron lines are more home/small-medium business-oriented devices, and here Dell is also using the Ryzen 7 2700U and Ryzen 5 2500U processors to offer peak Mobile APU performance. Designed more as a workhorse than for aesthetics, the Inspiron 5000 will offer AMD parts with 15.6-inch and 17-inch displays in a chassis that can support dual HDD/SSD options. The unit also comes with an optional Radeon 530 discrete GPU, which has 384 compute units based on AMD’s older GCN 1.0 architecture. This comes across as very odd, given that even the Ryzen 5 has 512 compute units of the newer Vega architecture. I can only assume that this provides extra displays for very specific customers, though for most it would seem an overly pointless addition.

    Plenty of modern games play somewhat smoothly at 4K on a 1080 Ti, but could use a bump up in fps. Once you see 4k gaming, it's kind of hard to unsee, which is why I haven't bothered to buy a 1440p gaming panel to complement my professional panel. I'd gladly pay another $700 + the cost of a 4K Gsync/Freesync monitor next year to upgrade the 1080 Ti to something that can crush any game at 4K, but it doesn't look like that product will hit the market in 2019 because AMD is so far behind, and everyone's making tons of money selling GPUs for crypto.

    Those who buy price gouging items walk into it willingly. Gsync vs Freesync, for example. Reply

    I hope you'll get better soon Ian. I don't think I would be able to type a single sentence if I were in your shoes, I have to admit am impressed by your resilience. Reply

    why no ryzen 7 8 core for mobile? Reply

    At last, desk top apuS. Its very exciting.

    It bears noting, that liquid cooling is getting to be mainstream, and apuS DO allow both cpu & gpu to use a single cost effective cooler - ~$100usd.

    Desirable as gpu LC may be, it tends to be impossible/difficult on discrete gpuS physically. LC cooling the APU's gpu is very simple.

    The usual chip TDP constraints can be greatly loosened if LC is assumed (as in the ~300w LC vega).

    "The Ryzen 5 2400G will run at up to 3.9GHz with 4-cores/8-threads and 11 CUs, a 65W TDP, and a price of $169."

    Rumors of apuS w/ 28CUs dont seem fanciful, they seem conservative.

    My guess? is most moboS would handle a 180W module in their socket?

    An 8GB vega 56 is 210W TDP.


    Apr 14, 2017 - 1. TDP is not electrical watts (power draw), it's thermal watts. 2. Published processor TDPs are often rounded up to fit a desired specification. For example, AM4 motherboards are specd to run processors with 65W and 95W TDPs. It gives motherboard manufacturers and system builders a thermal framework"

    You will be feeling like crap a long time. Take it easy, you’ll only get worse. Thanks for the info on new desktop w/ GFX.
    Any info on that is appreciated.
    I just got over the flu, caught in Vegas. Lasted 5 weeks and I took the advice and got a flu shot in November. Big help....NOT

    "To accompany the HP Envy x360, the Lenovo Ideapad 720S, and the Acer Swift 3, Q1 will see the launch of a new HP (under embargo until later this week),"

    Now that the week is almost up, has anyone seen news as to what that new HP device is?

    Did AMD have a solution to the current impossibility of buying an AMD GPU? If we can't deal actually buy their GPUs, AMD might as well not exist, and in a very real sense they don't exist right now. Reply
  • 5080 - Sunday, January 21, 2018 - link

    Well, they do exist, but all are bought up by coin miners. Great for AMD, not so great for gamers and others that need a fast GPU. Reply

    Hi Ian, are you still going to update this article with Lisa Su's interview and the rest of AMD's announcements? Reply
