VRAM and memory store the same thing—model parameters—and the only difference is distance from the chip; VRAM is closer and therefore faster.

UnverifiedSystem memory and VRAM are two different memory pools and cannot simply be added together to equal total available VRAM.69% similarVerifiedThe memory wall refers to the phenomenon where, when chip compute power grows faster than memory bandwidth, actual performance is bottlenecked by memory access speed rather than computing capability.69% similarUnverifiedWhen running a 1B-parameter model purely on CPU, the bottleneck is mainly memory bandwidth rather than compute: every generated token requires reading the model weights from memory once, so quantization level, CPU core count and memory frequency greatly affect speed.68% similarUnverifiedTwo constraints of on-device AI are that the chip needs to retain compute redundancy, and that the model needs to be compressed for limited memory and power consumption.68% similar
