LLM Inference: KV Cache Fills Before Compute Limit on Consumer GPUs
The article explains the concept of the "ridge" in LLM inference, which refers to the point where a model's computation becomes limited by memory bandwidth rather than processing power. It details how this "ridge" is af…

LLM Decode Speed: Bandwidth and KV Cache Limit Performance on H100
A technical analysis reveals that for large language models running on hardware like the NVIDIA H100, decode speed at batch size one is primarily determined by memory bandwidth rather than compute power. The "ridge batc…

INT4 Weight-Only Quantization: Decode Speedup, Prefill Stagnation Explained
Weight-only INT4 quantization, while effective for reducing memory traffic and speeding up the decoding phase of LLM inference, does not improve the prefill phase. This is because prefill is compute-bound, meaning it is…
