Zen Cores and Vega: Ryzen APUs for AM4

It has always been expected that AMD would launch processors with integrated graphics on the main AM4 desktop platform. With over 120+ AM4 motherboards in the market, most of them with display outputs , the launch of APUs beyond the units based on the last generation CPU microarchitecture would normally have been alongside the original Ryzen launch, however AMD felt that a focus on the silicon for mobile platforms first was part of the corporate strategy. Nonetheless, AMD is aiming their Ryzen APUs at consumers to replace a Core i5 and low end GPU setup.

APUs from $99

Unlike other Ryzen launches, AMD is starting with the low and mid-range processor versions first. This comes in the form of the Ryzen 5 2400G and the Ryzen 3 2200G, where ‘G’ is using for graphics. If that reminds you of a series of processors that was recently released by Intel, then it is either a case of Intel and AMD working on this naming strategy, or sheer luck that both of them is using the same designation.

Despite the Ryzen 5 2400G being classified as a ‘Ryzen 5’, the specifications of the chip are pretty much the peak specifications that the silicon is expected to offer. AMD has stated that at this time no Ryzen 7 equivalent is planned. The Ryzen 5 2400G has a full complement of four cores with simultaneous multi-threading, and a full set of 11 compute units on the integrated graphics. This is one higher than the Ryzen 7 Mobile processor, which only has 10 compute units. This translates as 704 streaming processors, compared to 640 SPs. Aside from the full set of hardware, the CPU frequency is very high, similar to the standard Ryzen 7 desktop processors: a base frequency of 3.6 GHz and a turbo of 3.9 GHz will leave little room for overclocking. Yes, these chips are overclockable. The integrated graphics frequency will default to 1250 MHz  and the total chip TDP is 65W. Maximum supported memory frequency will vary depending on how much memory is used and what type, but AMD lists DDR4-2933 as the support for one single-sided module per channel.

A side bit of news on the Ryzen 5 2400G is that it somewhat replaces the Ryzen 5 1400 at the $169 price point. Both chips will continue to be sold, but at this price point AMD will be promoting the 2400G over the 1400.

The cheaper $99 processor is the Ryzen 3 2200G. The specifications follow the other Ryzen 3 processors already in the market: four cores, and no simultaneous multi-threading. The rated frequencies, 3.5 GHz for base and 3.7 GHz for turbo, are slightly below that of the Ryzen 5 2400G but are still reasonably high – despite this chip being rated for 65W, the same as the Ryzen 5 2400G, users might expect this processor to turbo for longer within its power window as long as it is within its thermal boundaries. The suggested retail price of $99 means that this is the cheapest Ryzen desktop processor on the market, and it crosses a fantastic line for consumers, with four high-performance x86 cores under the $100 retail line. The integrated graphics provide 512 streaming processors, identical to the $169 processors from previous generations, but this time upgraded with the Vega architecture.

Within the presentations at Tech Day, AMD typically provides plenty of performance data from their own labs. Of course, we prefer to present our own data obtained in our labs, but combing through AMD’s numbers provided a poignant point as to just how confident AMD is on even its low end unit: using the 3DMark 11 Performance benchmark, the Ryzen 3 2200G (according to AMD) scored 3366 points, while on the same benchmark Intel’s best integrated graphics offering, the Core i7-5775C with embedded DRAM, scored only 3094. If we took this data point as the be-all and end-all, it would come across that AMD has broken Intel’s integrated graphics strategy.

One of the other important elements to the Ryzen APU launch is that both processors, including the Ryzen 3 2200G for $99, will be bundled with AMD’s revamped Wraith Stealth (non-RGB) 65W cooler. This isn’t the high-end AMD cooler, but as far as stock coolers go, it easily introduces a $30 saving to any PC build, reducing the need to buy a hefty standard cooler.

AMD vs. Intel

AMD’s main target with these new processors is to offer something Intel cannot: a combined processor and graphics package. Much like a number of AMD’s previous generation of products, the focus is two-fold: offering more performance at the same price, or being cheaper at equal performance.

For the first part of that argument, about having more performance at the same price, AMD suggests the following competition for the Ryzen 5 2400G:

  • $169 Ryzen 5 2400G (4C/8T, 3.6 GHz, 704 SPs)
  • $182 Core i5-7400 (4C/4T, 3.0 GHz, 24 EUs)
  • $187 Core i5-8400 (6C/6T, 2.8 GHz, 24 EUs)

AMD cites that in its internal testing, the 2400G scores 20% higher than the i5-8400 on PCMark 10, and can post 1920x1080 gaming results above 49 FPS in titles such as Battlefield One, Overwatch, Rocket League, and Skyrim, having 2x to 3x higher framerates than Intel’s integrated graphics.

For the Ryzen 3 2200G, the competing products are less well defined:

  • $99 Ryzen 3 2200G (4C/4T, 3.5 GHz, 512 SPs)
  • $117 Core i3-8100 (4C/4T, 3.6 GHz, 23 EUs)
  • $84 Pentium G4620 (2C/4T, 3.7 GHz, 12 EUs)

Again, through its internal testing, AMD is stating that the 2200G scores 13% higher than the Core i3-8100 in PCMark 10, as well as being within a few frames of the Ryzen 3 2400G in titles such as Rocket League, Skyrim, and Battlefield One.

The other side of the argument is price for the same performance. For this comparison, AMD suggests to test the new APUs against Intel processors paired with NVIDIA graphics, specifically the GT 1030. AMD’s data suggests that a Core i5-8400 with a GT1030 scores the same as a Ryzen 5 2400G in the 3DMark TimeSpy benchmark, although costing $290 (vs $169 for the APU) and drawing 30W more power.

Both of these APUs will be introduced to the market on February 12, which is when the review NDA also lifts for the media. We have a number of the required Intel processors to test against, and we also ordered a GT 1030 for additional testing points, however the retailer sent me an LED kit by mistake. Hopefully it can get switched around with enough time for testing.

AMD vs. AMD: Raven Ridge and Bristol Ridge

These two new APUs have the internal codename of ‘Raven Ridge’ to signify the family of products. AMD also has ‘Bristol Ridge’ already in the market, using the previous generation of CPU cores and previous generation of integrated graphics. AMD has not actively promoted Bristol Ridge to the public in any serious way, with these parts being hold-overs from the previous platform and designed to be a quick fill within AMD’s product line. To that effect, Bristol Ridge processors were only available for OEMs at the beginning for pre-built systems, and AMD only made them available to the public within the last few months. To our knowledge, AMD did not initiate a review sampling program to the press of these processors either.

With the launch of the two new Zen-plus-Vega Raven Ridge APUs, the Bristol Ridge processors will still continue to be sold. AMD’s reasoning revolves around offering choice in the market, particularly to its OEM customers, and has stated that the two products offer different features and is thus not competing on price. It is clear to say that for anyone buying a new system, the newest products offer the better value: a much higher per-core performance, improved thermal budgeting, newer integrated graphics, and ultimately the core design is the future of AMD. The only items that Bristol Ridge brings to the table now are the legacy aspect, to replace like-for-like, and the offer of a number of 35W-rated products. Bristol Ridge PRO processors are also on the market, offered alongside the new Ryzen PRO with Vega (more on this later).

Squaring up the competing parts shows that:

Given the performance uplift we have seen from previous generation A-series processors to the Ryzen desktop parts already, the new APUs should put the nail in the coffin for older AMD parts.

    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.

    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.
