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.

    Too much. About 2000 IU/day is optimal for minimizing all-cause mortality. Perhaps more can be supplemented in short spurts, however.

    It might be possible to safely exceed 2k IU/day if also supplementing magnesium and/or vitamin K, since one of the down-sides of overdosing Vitamin D is calcification of blood vessels.

    Anyway, Vitamin D isn't the only proven immune booster. Garlic is another good one.

    Endocrinology professor once said that the nations with the highest incidences of skin cancers (Australia) also have the lowest rates of population with low vitamin D, even in the Southeast United States people are going outside less and less; especially in the older populations. Not to mention the younger age groups with the phone attached to their face 24/7, and most people over 65 will need 2000-5000units of Vit D3 supplementation/day. However, in extreme cases a once weekly dose of Vit D2 1.25mg (50,000 units) once weekly for 12 weeks then reassessing lab values will render >45ng/dl will will be about where most people need to be. Then daily normal supplementation can continue from there. Endo professor said people who smoke need to avoid Vit A, and Copper supplementation unless they are in high risk of Macular Degeneration due to the increased risk in smokers of Vit A and Copper supplementation causing increased correlation of cancer. However he always emphazies that study x and study y can generate relevant data, and one study can "disprove findings" of another, because CORRELATION does NOT prove CAUSATION. Reply

    Yeah, here's another tidbit for you all to research...SELENIUM. 95% of American diets are severely deficient in Selenium. Selenium is an immune system regulator. Best source of Selenium = Brazil Nuts. In fact, not one to spread conspiracy theories (ok, yes I am), but I read a rather in-depth article once by an AIDS researcher that claimed that AIDS isn't even caused by HIV (like conventional "wisdom" claims), but rather every subject he took samples from and tested that had AIDS actually was severely deficient in Selenium in their body. Since I've been eating 1 brazil nut a day, I haven't been sick in YEARS. Most I've ever had was a sniffle, but it goes no further into my RT than my nose. Check it out. Reply

    Too much selenium is strongly linked to development of insulin resistance. So, be careful with long-term selenium supplementation and Brazil nut consumption. One/day is probably fine, but not much more. Reply

    @Ian ...

    "It is our understanding that the 12nm process is essentially a 14+ process for GloFo"

    Would you please a credible source for that statement. Say, EETimes or other such Industry outlet rather than an garnished from sites who do nothing other than plagiarize work that fits into the point they are try to make.

    I too have read on-line media's dismissal of GloFo 12nm process. Everything that I have read on this matter is based upon an early on-line media piece highly critical to AMD that tried to minimize the impact of 12nm. GloFo on their website specifically states that 12nm is a NEW process node and it is 12nm. GloFo has announced that 12nm IS 12nm, a new shrink from 14nm. Announcing falsely would create all sorts of problems with the FTC and lawyers who do nothing but specialize in Class Action suits. Case in point Intel is getting it's clock cleaned due to their knowledge of and failure to eliminate the Meltdown hardware flaw.

    As with ALL process nodes, the entire die is not fabbed with say 12nm or 14nm or for that matter the upcoming 7nm node. There are components within the die that can be and sometimes must be greater in size than the process node taped out for the silicon.

    Perhaps you shaould also take the time to ask Dr. Su directly if ONE DESIGN covers ALL EPYC, RYZEN and Threadripper design? In my opinion EPYC is a design similar to Zeppelin and Ryzen but with some major design differences that make a server processor.

    No sense speculating on something if you can ask AMD CEO directly.

    They may have been able to reduce the minimum possible feature size in a way that lets them claim a new number, but that doesn't necessarily mean that the performance of a finished product is significantly different.

    It's impossible to know until products are out in the world, because all we have for now is GloFo PR statements, which are going to make things look as rosy as possible.

    The Zeppelin die covers all Ryzen, Ryzen Pro, Threadripper, and EPYC CPUs. However, there are parts disabled on those designated Ryzen and Threadripper that are enabled on Ryzen Pro and EPYC. I do not know for certain if there is any feature differences between Ryzen Pro and EPYC but judging from AMDs own information there doesn't seem to be. Reply

    based on improvements in the 10-20% range calling it "essentially a 14nm+ node" seems reasonable to me.

    Huh?

    Meltdown - Not relevant here.
    TSMC called their 16nm++ ( or was it 16nm +++ ) as 12nm.
    And FTC would have a problem with Intel because their 10nm really should be 7nm by Fab Industry measurement.

    And it is not garish, it is straight from GF investor conference.

    Design? Speculate? Is Goldmount the same design as Goldmount+. Do QA and feature / yield test accounts for design? And more importantly, do even any other chip maker disclose these information? There is something call trade secret.
