Desktop Ryzen still suffers with thermal/power efficiency issues compared to desktop Intel cores, so I wonder if they've managed to address that issue for these mobile cores. If not, I wonder how customers will feel about paying a battery life tax for better performance...<p>Incidentally, AMD GPUs have been at a disadvantage compared to NVIDIA's in the power management area for a while, as well. Which is unfortunate because they're very good cores with (arguably) a better feature set for compute/rasterization than NVIDIA's. Intel seems to have the market for low-power GPUs on PC sewn up as well. If AMD manages to make improvements here they could put out a very compelling product, if only because you wouldn't need GPU-switching in your laptop (with all the hassle that entails) and it'd be easier to substitute a laptop for your desktop when you do compute-heavy work.<p>For example, <a href="https://www.anandtech.com/show/11658/the-amd-ryzen-3-1300x-ryzen-3-1200-cpu-review/16" rel="nofollow">https://www.anandtech.com/show/11658/the-amd-ryzen-3-1300x-r...</a> shows worse idle power draw and worse load power draw for Ryzen. In desktop cases this gap doesn't matter as long as you have a good heatsink+fan but it will map to worse battery life and worse noise/thermals in a laptop. (An extra thirty watts in total system draw under load can add up on your utility bill, though.)<p>Power draw on AMD's GPUs is not great either, unfortunately: <a href="https://www.anandtech.com/show/11717/the-amd-radeon-rx-vega-64-and-56-review/19" rel="nofollow">https://www.anandtech.com/show/11717/the-amd-radeon-rx-vega-...</a>
And past GPUs they've released also had issues with drawing more power over the PCIe slot than it was rated for (and exceeding their TDP in general, I believe).
