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.

    Flu Vaccines are CDC predictions for which flu will be seen in a given season, it is rarely above the teens in effectiveness for the exposed populations but the groups who get the vaccine and then still get exposed to the flu they usually have a milder case of the flu due to exposure to those antibodies. Inoculation is an old science, effective for some things but a virus with more strains and mutations each year will greatly limit the ability of any vaccine. Polio vaccine was wonderful in that polio wasn't hybridized and constantly changing, it's virus was very mundane and boring which made it quite predictable. Also flu vaccines are big money for everyone involved, there is ZERO money to be made in curing anything anymore. Just look at Hep C "cures" like Solvadi and Harvoni are over 84k to 128k for a 12 week regimen all because they have less risks and are comparable to Interferon treatment along with Ribavirin. Should Jonas Salk have charged the equivalent of 84-128k for the polio "cure"? No! In America should it be okay for Sanofi and Lilly to charge 500+ dollars for Lantus/Basaglar/Humalog/Humulin etc etc....big money, big interests Reply

    Part of the reason for low efficacy rates is because of the why flu serums are 'grown'...eggs. They have found that the viruses are mutating and become less effective against the ones in the wild. The serums grown in animal cells (for those with egg allergies) have been found not to suffer from mutations.

    More significantly, there has been significant progress with a new type of flu vaccine that uses our skin cells to develop antibodies based on the actual DNA of the particular virus. This is 'injected' intradermally via a 'gun' (similar to the hypospray in Star Trek lore). Expected to see human trials in the next 5 years or so. Very cool.

    But I smoke heavily, drink coffee almost continuously, eat poorly and avoid the Sun, and don't take vitamin supplements.

    I haven't been sick in decades ...

    Not that I would advise anyone to smoke nor offer medical advice but there's flu shots (which I also don't have) that will reduce your vulnerability rather than copy my lifestyle.

    The problem with that attitude is that you are chipping away at your body's natural defenses against all kinds of diseases, such as COPD, over time.

    You are born with a lot of over-provision inside each of your organs. Those activities are eating away faster than normal. What happens when you run out of extra "space"? Same as on an SSD Degraded performance or size.

    Everything is fine... until one day, it's not. I have a co-worker somewhat like you describe (though he probably ate a bit better than that). He had a massive heart attack. He's still with us, but such an event is probably more costly and disruptive to one's life than simply taking better care of yourself. Reply

    BTW, coffee is probably a net-positive, as long as you keep the cortisol in check and don't add lots of sugar. Reply

    It is incredibly easy to get Vitamin D outside of the Pacific Northwest or similiar environments...

    "If you're fair skinned, experts say going outside for 10 minutes in the midday sun—in shorts and a tank top with no sunscreen—will give you enough radiation to produce about 10,000 international units of the vitamin. "

    Um, so exactly how does this help in winter, where the only exposed skin most people have is on their face and hands?

    And getting a couple hours/day of direct sun exposure on your face is going to take its toll on skin aging and cancer risk.
