Nanbeige4.3-33B vs Qwen3.8-27B: Benchmark Claims Meet Hardware Reality

The author benchmarks Nanbeige4.3-33B against Qwen3.8-27B on an A100-80GB GPU, finding Nanbeige wins select benchmarks but fails to deliver its claimed 512K context on a single card due to high KV cache overhead from its Llama architecture, suffers from excessive chain-of-thought tokens that break coding tasks, and lacks vision capabilities, while Qwen's linear attention enables longer context and multimodal support.
