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.

    By that logic I could claim the GE chips have a "nominal" TDP of 45-65W. The Zen and Vega cores alike are capable of excellent scaling and they're actually more efficient the lower you go. A 2700U at 25W would be more efficient than GE at 35W.

    They're at a disadvantage competing against 45W chips used solely in gaming laptops with dGPUs... yes. But being the little guy they need to attack the biggest market segments first. The ideal candidate to go after high-powered gaming laptops would be a lower-TDP dual-CCX Ryzen with no iGPU. But again, it's too low volume for them to think about such a thing at this point in time. Maybe if you're lucky you'll see something after Zen 2.

    I've got a 45w Intel i5 6300hq with a GTX 960M.

    Socketed, I agree, BGA would probably be required to keep the power down, same as it is on mine, but there's plenty of market for 25w or higher. With the aggressive clock control I still get 10 hours on my laptop when working at a tower site and it's under 7lbs. Perfect fit, but of course I'd always like more CPU power.

    This chips look too huge for today's laptop they would have to have a different packaging

    But there are crazy people who build huge laptop with desktop chips

    I don't see why they couldn't be repackaged. In fact I'd expect them too. There's a glaring hole in their notebook chip lineup and these fill it. Reply

    I not sure anybody would want it - at 65W this is same as 9805G in my XPS 15 2in1 and the dell has both a more powerful CPU and more powerful GPU (20 cu's vs 11's )

    So far with my XPS 15 2in1 my biggest concern is GPU compatibility - CPU on it awesome - I can believe a computer half as thin as my Lenovo Y50 can be so fast. Beautiful 4K screen - I had to find workaround in Photoshop for my eyes.

    Yes but at what price? These would be considerably cheaper. I do agree though that the performance/power curve may end up doing a 45W SKU a disservice and could therefore be useless. Reply

    How brew NAS, low end home servers, and/or custom routers might be able to make use of these. Does anyone know if they support ECC. If there are boards that support ECC and/or slim mini-ITX with multiple GBe ports, I'd build with them. Reply
  • Trixanity - Monday, April 23, 2018 - link

    All Ryzen chips support ECC memory. Problem is most boards do not. Probably because they don't want to validate it. Reply

    I'm trying to find somewhere on AMD's site where they actually specify ECC support. Got a source? Reply

    Ya, could be a sweet low(er)-power DIY transcoding NAS CPU. Reply
