Qwen3-0.6B-FP8-KV

Lightweight OCP FP8_e4m3 quant of Qwen3-0.6B with end-to-end KV-cache FP8 support, built with AMD Quark for ROCm.

Introduction

Qwen3-0.6B-FP8-KV is an OCP-standard FP8_e4m3 quantization of Qwen/Qwen3-0.6B, produced with AMD Quark.

Quantization Strategy

  • Quantizer: AMD Quark v0.9+
  • Numeric Format: OCP FP8_e4m3, symmetric per-tensor
  • Scope: All Linear layers (excl. lm_head), activations and the KV cache
  • Block Size: 128 (OCP-aligned)
  • Calibration: 128 Pile samples
  • Metadata: scales & block info in JSON; weights in SafeTensors

Performance Snapshot

Metric FP16 Baseline FP8_e4m3 Quantized
Wikitext2 Perplexity ~22.1 ~25.8
Memory Footprint 1.0× 0.50×
Inference Throughput 1.0× 1.3×

Evaluation

We measured perplexity on WikiText2:

  • FP16 (Qwen3-0.6B) → 22.1 PPL
  • FP8_e4m3 (this model) → 25.8 PPL
