Unverified16GB of VRAM determines the size of models that can be fully loaded onto the GPU, while 64GB of system memory allows larger models to run via CPU offloading, but at reduced speed.77% similarUnverifiedTraditional AI chips (GPUs or TPUs) store model weights in memory and compute units read and execute them on demand, with a large amount of time and energy consumed in weight transfer.77% similarVerifiedThe GPU memory hierarchy from fastest to slowest is: registers, L1 cache/shared memory, L2 cache, global memory (VRAM).77% similarUnverifiedllama.cpp allocates VRAM on demand, while vLLM pre-allocates a specified proportion of VRAM via the --gpu-memory-utilization parameter (including the KV cache and the model itself).76% similarVerifiedThe LLM decoding process is memory bound, with the GPU spending most of its time waiting for data transfers during token-by-token generation.76% similar
