Then again, several Windows laptops such as Microsoft Surfacebooks also come with soldered RAM, so it isn't just Apple doing it.Ī few Chinese modders discovered a rather simple workaround for the soldered parts conundrum on their M1 Mac Mini.
The same holds for Apple's newly-released M1 MacBooks and Mac Mini.
Also, there is no commercial DRAM being produced on a 5nm process, and there may never be since capacitors, like flash memory cells, are analog devices that need physical space to store charge, and 5nm is currently too small.MacBooks have been long reviled for their soldered components, which makes upgrading any storage/memory component virtually impossible. First, each DRAM cell has a transistor and a capacitor - which needs regular refreshing, hence the Dynamic in the name - and with 16 billion transistors on the chip, there would be none left over for the CPU, GPU, Neural Engine, etc. This is unlikely for several reasons, and I'll give two here. Update: Some writers are speculating that the M1 chip has up to 16GB of onboard DRAM, probably thanks to a confusing slide in the Apple announcement. Since the 13-inch MacBook Pro and the Mini have fans, I doubt the 16GB limit is thermal. I'll expect the future 16-inch Mac Pro to have a more powerful chip - M2? - and support 64GB or more memory, with or without a discrete GPU. So the performance is improved over discrete GPUs, but the shared memory may throttle some graphically intense applications. Graphics resources, such as textures, images and geometry data, can be shared between the CPU and GPU efficiently, with no overhead, as there's no need to copy data across a PCIe bus. means that the GPU and CPU are working over the same memory. What is Unified Memory? According to Apple: What's more, the touted Unified Memory Architecture just means that 16GB is shared between the CPU and graphics. The new M1 iMac highlights everything that's wrong with AppleĪpple spent a lot of time emphasizing the power of the new M1 chip, but barely mentioned the 16GB memory limitation.
