AMD has officially added energy-efficient Ryzen 3 and Ryzen 5 APUs to its product lineup. The new processors with integrated Radeon Vega graphics, have a 35 W TDP, and at this point in time will only be initially available to system integrators enabling the latter to build small form-factor PCs, rather than directly selling at retail.

AMD’s Ryzen 3 2200GE and Ryzen 5 2400GE APUs pack four Zen cores running at 3.2 GHz default frequency (with multithreading for the Ryzen 5) and integrated Radeon Vega 8 or Radeon Vega 11 graphics respectively. In a bid to reduce TDP of the APUs to 35 W compared to the 65W vresions, AMD had to reduce clocks of the GE chips by 300-400 MHz as showin in the table below. For the integrated graphics, they remain untouched: the Ryzen 3 2200GE has 512 stream processors at 1100 MHz, whereas the Ryzen 5 2400GE has 704 SPs at 1250 MHz. The supported memory controller also retains parity: two DDR4 memory channels up to DDR4-2933.

The new APUs from AMD featuring a 35 W TDP are designed for the AM4 socket, but need appropriate BIOS support by the motherboards. As the Ryzen 3 2200GE and the Ryzen 5 2400GE are made available to system integrators first, their drop in compatibility with retail motherboards is not a priority for AMD just now. Motherboard makers, namely ASUS, have been adding support for the new APUs to their BIOSes in the last few weeks.

Despite the fact that AMD lists the new 35W APUs on its website, the company has not included the chips into its pricelist and it is unknown how much do they cost. Retail versions of AMD’s 65W Ryzen 5 2400G and Ryzen 3 2200G are priced at $169 and $99 respectively and come with coolers - it is likely that the tray prices of the 35W parts will be slightly beneath this.

    Would imagine that you could find "industrial" SKUed motherboards that supports ECC. Reply

    Most AM4 board makers have at least one SKU with fully-enabled ECC support (not just using ECC RAM as non-ECC). You just have to look at the specs. Reply

    The APUs would not be good for home servers. They only have 8 PCIe lanes, limiting the hardware capability to the exact same as a Ryzen CPU with a video card on a X370/X470 motherboard. Reply

    What do you think requires "home servers" to have more than 8 PCIe 3 lanes? A regular Ryzen + discrete GPU would cost more than these and consume a bit more power, so even with everything else being equal these would be better. Reply

    Any source for Ryzen APUs only having 8 PCIe lanes? The old Bristol Ridge APUs had 8 lanes, but the Raven Ridge APUs have 16. Only 8 are supposed to go to the GPU PCIe slot, but they have an additional 4 for NVME storage and 4 for the chipset, which has PCIe 2.0 lanes as well, if I'm not mistaken. So you are making something out of nothing, especially since few home servers should be limited by PCIe connectivity and if they are, the PCIe stuff would likely cost an order of magnitude more than this APU anyway.

    Yes. In short, u r in the same postion as w/ a ryzen and an 8 lane dgpu. Its very doable considering graphic is catered for.

    Afaik, the onboard nvme m.2 port, is just a modified pcie3 x4 slot, & i imagine there are adapters for it, so the apu in reality has 12 spare pcie 3 lanes, plus the chipset's switched; lanes, ports and devices as you say.

    AMD's website says "PCI Express Version: PCIe 3.0 x8"
    We know they're not counting the chipset and M.2 lanes in that but it's still 8 less than the other Ryzen models.

    I wouldn't mind someone bringing out a NUC style Raven Ridge mainboard or at least a mini ITX with a sub 35W APU, maybe just a 15W U one. There were some motherboards by Biostar that used AMDs old APUs like that. Reply

    See how cute the apu is?

    Unusually, their wimpiest 2 apu versions are introduced to the market first, because thats where it's perfect - the huge and juicy, lean running mobile market.

    Already we see that same pair, spun into 3x ~discrete segments now.

    Not a bad start for their wimp version, and still~40w of tdp wiggle room for the next version(s).
