VerifiedThe latency improvement rate of DRAM memory is only about 7% per year, far below the rate at which CPU/GPU performance doubles every 18–24 months according to Moore's Law.70% similarUnverifiedThe 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.68% similarVerifiedFor modern CPUs and GPUs, memory bandwidth is often the true bottleneck for inference speed rather than the compute units' arithmetic throughput, which is why quantization can bring speed improvements.66% similar
