SK Hynix, a memory manufacturer, has just announced an LPDDR5X memory chip with unprecedented capacity and frequency. This 64-bit interfaced chip operates at 8,500 MHz in SDR equivalent and offers a capacity of 24 GB.
24 GB in a single chip.
To give you an idea, Macs equipped with an M2 chip are currently equipped in the best case with two LPDDR5X 6400 chips and this novelty from SK Hynix could therefore increase the overall bandwidth – which would increase to 136 GB /s, against a little 100 GB / s for the moment – while doubling the maximum capacity of RAM, which would therefore be 48 GB.

Remember that Apple places memory as close as possible to the CPU and GPU in its systems on chip and that the different variants of M2 chips include two — M2, 128 bits —, four (M2 Pro, 256 bits), eight (M2 Max , 512 bits) or even sixteen chips interfaced on 64 bits, as with the M2 Ultra of the Mac Pro and its 1024 bit bus.
In iPhones, Apple only integrates a single chip, but the new component from SK Hybix will probably not find its place in an iPhone 15 Pro: Apple tends to limit RAM and going from 6 GB to 24 GB seems unrealistic . On the Android side, there are already smartphones that take advantage of it, such as Oneplus Ace 2 Pro, but memory management is not necessarily the same in Android, and some manufacturers try to put more memory in order to have the most big… spec sheet.
Finally, as explained Anandtech, the goal is not always to integrate more memory or to offer better performance: this chip can also be used in systems that rely on classic DDR5 in a PC. At this frequency, a single 24 GB chip can replace two DDR5-4800 modules with roughly equivalent performance but much lower power consumption in a much smaller volume.
