Today AMD is finally lifting the lid on its long-awaited desktop Zen2 based APU family. Using the same silicon as in the Ryzen Mobile 4000 family, AMD is pumping it up into 35 W and 65 models in the same AM4 platform that is in use today. There has been strong demand from PC builders to release these chips, which were on the topics of forum conversation all the way back at CES. There’s only one downside to these new processors: you can’t buy them on their own. AMD states that the initial release of Ryzen 4000G hardware is for OEMs like Dell and HP only for their pre-built systems.

The new processors use the same 8-core Zen2 plus 8 compute unit Vega that we saw in Ryzen Mobile 4000 at the beginning of the year, but as with previous APU launches, the frequency and power thermals have been pushed up into more manageable desktop environments. To that end, AMD will be launching hardware in the Ryzen 7, Ryzen 5, and Ryzen 3 product lines at both 65 W and 35 W, all on the AM4 platform.

*PCIe lanes on the SoC are listed in GFX+Chipset+Storage

The top processor is the Ryzen 7 4700G, coming in at 65 W TDP with a base frequency of 3.6 GHz and a turbo frequency of 4.4 GHz. It uses all eight compute units for the graphics, running at a mind-numbing 2100 MHz.

At the lower end is the Ryzen 3 4300G, with four cores and eight threads, with a base of 3.8 GHz and a turbo of 4.0 GHz, which should mean that performance is very consistent. This part has six compute units for graphics, running at 1700 MHz.

Every version has a GE counterpart at 35 W, which for the most part reduces the base frequency and TDP only. The exception is the Ryzen 7, where 100 MHz is lost on turbo and 100 MHz is lost on graphics.

All the APUs support DDR4-3200, and have sixteen PCIe 3.0 lanes for add-in cards, as well as four PCIe 3.0 lanes for storage. On the PCIe lanes, the reason this is PCIe 3.0 and not PCIe 4.0 is because the equivalent mobile chip was built with eight PCIe 3.0 lanes for add-in cards, to save on power in a mobile environment. AMD sees these chips being used mostly on their own without a separate discrete graphics card, given that the company already has the Ryzen 3 CPU family for those that want discrete graphics.

At the same time as the Ryzen 4000G APUs, AMD is also launching the Ryzen Pro 4000G versions for the commercial market. These specifications mirror the standard Ryzen counterparts, but fall under AMD’s Pro Technologies feature set, with additional security, manageability, and business ready pillars. This includes full memory encryption and support for DASH management, OS image stability over 18 months, guaranteed processor availability for 24 months, and enhanced QA.

So they are OEM only? What?

Just to be clear, AMD specified OEM and not system integrators (SIs). On our call, AMD clarified that the market for its APUs is skewed very heavily towards the big mass-market prebuilt customers like HP and Dell, rather than custom home builds. The numbers quoted were around 80% of all APU sales end up in these systems, and by working with OEMs only, AMD can also help manage stock levels of the Renoir silicon coming out of the fabs between desktops and notebooks.

What this means is that unless you are choosing to buy a pre-built office-focused business PC, then the only way to get hold of these processors would be through distributors who are selling them piecemeal – AMD is not creating official boxes and bundles with coolers for these processors.

Those pre-built office-focused business PCs are expected to be out shortly. Just in case you control a corporate budget and need a few hundred of them.

Will we ever get Ryzen 4000 APUs for Desktop?

AMD says that they are planning a consumer-grade release of APUs ‘soon’. It was stated in our briefing call that there will be a launch of a future Zen2 APU for the consumer market compatible with 500-series motherboards. The company specifically did not say 400-series, but did clarify that the 4000G series announced today was for 400 and 500 series.

When exactly this launch will come, and what it will be, and what price ranges AMD will be aiming for is unclear. As mentioned, we were discussing Zen 2 based Renoir desktop APUs with vendors back in January, and at this point it certainly feels late to the game. Could AMD be hiding something up its sleeve? A PCIe 4.0 version perhaps (would this require new silicon?) or maybe something up at the 105 W TDP performance level? It really is unclear.

There’s also some new Zen+ APUs

For the lower end of the prebuilt market, AMD is also offering a new set of Zen+ APUs. These are the first desktop parts to carry the Athlon Gold and Athlon Silver branding.

Athlon Silver Pro 3125GE 2 / 4 3400 - 3 1100 4+2+2 35 W
PCIe lanes on the SoC are listed as GFX+Chipset+Storage

We believe these to be based on the same silicon as the Athlon Gold and Athlon Silver mobile parts. We're still waiting on full details for the 3000G family.

The Final Word: We were told that there will be a reviewers’ guide shared with us. Whether that is for these OEM-only parts, or for something upcoming, we don’t know. But we have our fingers crossed.

    Exciting stuff. As a happy 2200G user, I've got something nice to dream of now :) Also glad all the models are coming with SMT, as far as I can see.
  • dan_ger - Wednesday, July 22, 2020 - link

    That is a huge jump in frequency, you can almost double the clock speed on an overclock. I have not seen frequency jumps like that for a long time, impressive.

    I don't agree with your AMD valuation. Covid will be neutral to beneficial to AMD. You are right that small business is getting hurt and as a result tech and online conglomerates are benefiting. More remote operations, telecommuting, cloud, data center etc. Furthermore AMD has a clear path in CPU dominance to early 2022 with Zen 3 and this assumes that Intel gets their 7nm and urarch right. If Intel falters, AMD's dominance could persist longer. In either event, AMD is not standing still. They will have 5nm design coming to meet Intel at 7nm. Additionally, they have a monopoly on consoles AND Big Navi looks like it will compete with NVDA at the high end. I am expecting more market share gains in discreet for AMD. Look what happened to NVDA stock when it went from 6B to 11B. It seems AMD is on a similar trajectory. I certainly would not sell AMD now.

    Kinda disappointed by Ian's trolling headline.
    He knows full well that DIY versions us regular folk *can* buy are on their way. Plenty of Ian's peers & industry colleagues (Charlie at SemiAcccurate etc) have posted about this & AMD themselves have said the 4000 series APU's for DIY are coming soon. So the clickbait headline is unwelcome, from Anandtech & Ian especially (of course elsewhere on Reddit or Youtube & in those crazy forums, it's de-rigeur)

    Nothing wrong with AMD making some money by prioritizing Si to customers & markets that are worth the most, especially when consoles must be eating a lot of their wafer allocation in readiness for the upcoming release.
    Lisa Su hasn't become *the* highest paid Si valley CEO by setting her priorities just from what the enthusiasts & fanboys want.

    Charlie, from SemiAccurate, is informing that we may see Ryzen 4000 Desktop APUs later in August. I hope he is right.
  • andrellyra - Friday, July 24, 2020 - link

    wouldn't the mobile version of the APU have just 8 PCIe lanes?
  • Spunjji - Friday, July 24, 2020 - link

    Nope - 8 for a GPU, 4 for NVMe and another 4 for chipset / NVMe. I think there may also be a couple of lanes for WiFi/etc. on top of that.
  • Iketh - Friday, July 24, 2020 - link

    article states maybe a 105w zen 2 renoir.... what on earth for??? clearly the current silicon is limited to ~4.2ghz based on all turbo frequencies, so more power is yielding little to know gains
  • mr_tawan - Friday, August 7, 2020 - link

    I saw these processors listed in some retailer here, although with no price. There are some reviews already as well.

    My guess is some of these retailers act as an OEM but sells parts individually.

    Or may be because I'm not in the US, but in some of the third world country where the APU are in higher demands :).

    After more than 3 months from the launch, there are zero desktop systems available using them in Italy. Do they really exist?
