Prime Day 2026 深度解码：当消费主义狂欢遇上技术民主化，$280 折扣背后的产业逻辑

// 简化的手机定价模型：技术折旧系数计算
interface DevicePricingModel {

  ): number {
    const nodeFactor = (this.processNode / currentProcessNode) ** 1.5;
    const npuFactor = this.npuTops / marketNpuBenchmark;
    // 综合折旧：制程权重 60%，NPU 权重 40%
    return 0.6 * (1 / nodeFactor) + 0.4 * npuFactor;

// 折旧系数约 0.72，对应折扣空间 28%，与 $280 off 吻合
