AMD is launching a low-priced Zen APU on Sept. 8:

AMD is keeping the 20-year legacy of the Athlon brand alive with its new Athlon 200GE processors that come armed with Radeon Vega 3 graphics. AMD is bringing the new dual-core, four-thread Athlon 200G processor to market on Sept 8 for a mere $55. But it will be joined by beefier 220GE and 240GE processors in Q4 2018.

AMD is also introducing an Athlon Pro 200GE model and the new second-gen Ryzen Pro series for the professional/commercial market. The Ryzen 7 Pro 2700X, Pro 2700, and Ryzen 5 Pro 2600 models will come to market this year, but will debut in OEM systems from Dell, HP, and Lenovo. Launch times will vary by company.

[...] The Athlon 200GE does support the AVX instruction set, which is an advantage over Intel's Pentium and Celeron families. The new Athlon processors likely feature the same underlying design as the Raven Ridge 2200G and 2400G processors, albeit with a pared-down feature set that allows the company to sell Raven Ridge die that suffered defects during the manufacturing process.

[...] The Athlon 200GE only comes with 3 Vega CUs, which is quite the step down from the Raven Ridge 2200G's eight CUs. AMD claims the Athlon 200GE can handle 720p gaming with integrated graphics in various eSports-class titles, and also claims the processor provides enough performance to deliver solid performance when paired with a discrete graphics card, like the Nvidia GeForce GTX 1050.

220GE is based on the previous-generation "14nm" Zen, rather than being a "12nm" Zen+ part. The TDP is 35W. It is the very first Zen-based CPU to not support overclocking, although it does support memory overclocking. It supports 4K displays, USB 3.1, and NVMe SSDs.

    Finally competetion in the CPU+iGPU space that doesn't double as a stovetop.

    Really, 35W - while on the high side - are within the bounds of easy, silent-ish, and somewhat compact cooling.

    If only 25W parts will become easily available I can get back to having quiet computers again.

    Now if only x86 space could get back to publish the actual TDP-values instead of the "we guesttimate we are going to average about here".

    Try disabling "turbo boost" or whatever your processor calls it. For most usages, doing so will drastically cut down on the cooling requirements of your processor and not increase your processing time very much because of the thermal throttling the CPU does automatically, even with it on. I have two machines where the fan only comes on at boot time, due to my power settings not being applied yet, and my main machine only throttles up when all 4 cores are going 100%, the rest of the time it is on its minimum speed with a low throttle up under high loads to medium speed. Sometimes, I'll even underclock for day-to-day tasks, like browsing. Most modern CPU coolers can cool an underclocked machine completely passively and you don't really notice the difference, as the CPU is still orders of magnitude faster than I/O.

      Already turned off turbo boost, installed thermald, set the fans to not ramp up until about 2c after thermald target temp, and I've set the p-states to prioritize power over performance.

      I do however always keep the fans on at the lowest speed they can operate (less jarring with a slight ramp than the noise of a fan starting).

      But since I use a NUC (NUC7i5, specifically picked due to having better thermal than the NUC7i7) I can't replace the fan with something good (when using bigger setups I tend to favour noctua-fans in settings for less than 13dBA).

      The assumption that a modern CPU cooler can completly passively cool an underclocked machine either assumes a singificant airflow (like from the case fan) or that it has unobstructed interference with a huge thermal sink (like running it without a case that restricts airflow). Heck, I even get RPi's to throttle (with heatsink attached) when running them in some setups (my default cases however has troubles pushing them past 80c, thanks to two wellplaced vents)

        Either that, or we have different definitions of "underclocked" Some of my machines are locked at 1 GHz or less 50% of the time and when they aren't most activity doesn't last long enough to get them to 100%. God bless the "conservative" governor in Linux and the Windows equivalent.

          If you have a case fan, or just a big case, it will take quite a bit longer for the CPU to heat up (I did a similar thing with my P3 (Tualatin) when it was in an mid-tower).

          The CPU in my current NUC7i5 spends the vast majority of its time in the 600 to 720MHz range (I have a 15% load program constantly running, in addition to a constant 10% pulseaudio tax on the system).
          But the airflow of even the stock fan at minimum setting does a lot, the computer stayed at about 60.8c (it's target temp is 60c) when I accidently forgot two programs for 100% cpu each (so 2.2GHz without turbo boast) without the fan ramping - which shows just how little airflow is needed (but it still is a far cry to passive - this size of the NUC case means the device would thermal throttle within minutes if I turned off the CPU fan whenever I hit above 40%).

          (For sake of conversation - my definition of "underclocked" means "runs at lower than optimum speed for its workload within its thermal envelope" and my definition of "overclocked" is "needs active cooling" (so yeah, since the 486-era most consumer x86 CPUs has been sold pre-overclocked). And yes, it allows for devices being simultaneous overclocked and underclocked (this is generally a sign of a bad design, or a design being driven harder than what it is suitable for).
          Once you learn how to source stuff for long-term operation with minimum maintenence you start to develop a serious aversion towards fans _and_ running at high temperatures - which makes the current state of non-mobile CPUs quite depressing)
