Nvidia quietly launches 12GB RTX 5070 laptop GPU — midrange mobile gaming gets more VRAM amid the RAMpocalypse
What happened
Nvidia launched a 12GB RTX 5070 mobile GPU using 24Gb GDDR7 modules on a 128-bit bus, maintaining bandwidth parity with the 8GB version. This move addresses the memory shortage (RAMpocalypse) by offering higher capacity without bandwidth improvements. Neutral impact on spot prices as it targets a different capacity segment.
