  • because if the grid went down, these types of panels could keep feeding the house, out to the street, and electrocute a line worker

    The inverter in these is designed to shut down if it doesn’t detect a waveform from the grid to sync with - they are unable to create a 50 Hz AC wave on their own. As long as the hardware is legit (which is a big if with how easy it is to get unsafe junk in from China) there is no safety issue, it’s purely regulatory.














  • It’s for running AI on the GPU. You need a really expensive PC GPU to get more than like 16 GB of RAM or whatever, so the bottleneck for large AI models is swapping in and out data from system RAM over PCIe.

    The Mac has an SoE with unified memory, where the GPU can access all 192 GB at full speed, which is perfect for AI workloads where you need the GPU to access all the RAM. There’s always a tradeoff where the PC GPUs have faster processors (since they have a way bigger power budget), but the Mac GPU has faster memory access, so it’s not always a slam-dunk which is better.

    APUs/Integrated GPUs on PCs also have unified memory but they always targeted the low end so aren’t as useful.
