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.

    Only 15W chips. Reply

    The laptop chips have TDP configurable from 12-25W, and actually the 65W desktop parts can already be configured to 35W (if the motherboard supports cTDP). Reply

    Configurable, yes, but their nominal TDP is 15 and even a boost to 25W as some devices do isn't a substitute for a 35-45W SKU. According to the table in this very article the 65W parts only go down 20W. Reply

    Yes, AMD says that but at least in the MSI B350I Pro AC it can in fact be set to 35W. Either way they're all the same chip running at different clockspeeds and the power limit is enforced by software. Reply

    Also I'm not trying to imply the 35W SKU is pointless or anything, I'm sure they're binned to perform a bit better than the 65W chips at a reduced cTDP and/or the pricing is a bit more favorable for OEMs. Just pointing out the options for what you can do with existing SKUs. Reply

    Yes, I know they're the same chip but AMD (generally) dictates the limit. Seems odd that they would allow an out-of-spec TDP but either way AMD needs to compete with Intel's larger laptop SKUs but I suppose they think the payoff isn't there.

    Essentially what I'm saying is that they need to put Raven Ridge on a bga package and give them a 35-50W TDP range. Nothing more. It should be a trivial task but may not be worth the effort. Perhaps they'll do it next year with Zen2.

    "Nominal TDP" OK. They can be configured for 25W if the manufacturer desires. At that point, it's a 25W TDP chip. If hardly any OEMs are going for 25W configs, what makes anyone think they would want a socketed 35W chip in a mainstream laptop? Reply

    Nominal TDP just means it's what it was designed for. Intel also has SKUs with configurable TDP but generally OEMs stick with the recommended spec. What I'm saying is that AMD is at a disadvantage when competing against 45W Intel chips although they may not intend to do that. Reply

    On my 4+ year old Lenovo laptop, the TDP for the i5 4200M is 37W. This is not exactly thin and light, but your normal run of the mill laptop. Reply

    Normal is 15W or so today. Your normal, run of the mill laptop. Consumer and OEMs demand lower power, slimmer form factors, etc. Reply
