全球AI算力需求的快速增长正在冲击中国消费电子产品市场。作为国内最大电子产品集散地，深圳华强北的笔记本电脑价格近期出现大幅上涨，涨幅超过20%1，预计这一上升趋势至少将持续到8月份1。显示卡的价格波动更为剧烈，零售价平均上涨约30%12，部分型号一天内平均涨幅高达500至1000元2。华强北的商家已收到新一轮调价通知，预示8月份笔电零售价可能继续上涨1。
具体产品方面，RTX 5070显卡的零售价从4500元上涨至6000至6500元12，RTX 5080则从8000元攀升至接近12000元，涨幅高达5成12。价格波动之频繁，甚至出现了一日一价的现象，市场上标注"时价"的商品随处可见1。在电商平台层面，京东等平台已有多款显卡商品临时下架2。
这波价格上涨的深层原因在于上游芯片产能的结构性调整。三星、SK海力士等存储芯片巨头正将其70%至90%的先进产能转向高频宽存储器(HBM)以满足AI需求1，直接导致消费级DRAM和显卡用GDDR显存产能被严重压缩12。受此影响，GDDR7显存每2GB的成本上涨近20美元，8GB显卡显存成本增加约76美元(约514.2元人民币)，12GB显卡显存成本增加约114美元(约771.3元人民币)，16GB显卡显存成本增加约152美元(约1028元人民币)2。7月24日，英伟达已向其AIC合作伙伴发出涨价通知，并促成各大显卡品牌工厂执行全面封仓政策2。业界普遍预测这波涨势极可能延续至2027年1。
The explosive global demand for AI computing power has triggered significant price increases across consumer electronics in Shenzhen's Huaqiangbei market, China's largest electronics distribution hub. Laptop prices have surged more than 20% in recent weeks, with the upward trend expected to persist at least through August.1 Graphics card retail prices have climbed approximately 30% on average, with some models experiencing daily price adjustments and being marked with "time-based pricing."1
Specific graphics card models have seen dramatic increases. The RTX 5070 has jumped from 4,500 yuan to 6,500 yuan, while the RTX 5080 has risen from 8,000 yuan to nearly 12,000 yuan, representing a gain of roughly 50%.1 Huaqiangbei merchants reported receiving new pricing notifications, with some graphics card prices climbing 500 to 1,000 yuan daily.2 On July 24, Nvidia issued pricing notifications to its AIC partners, with specific policy details expected to be finalized by August.2
The root cause lies upstream in the semiconductor industry. Major storage chip manufacturers including Samsung and SK Hynix have redirected 70 to 90 percent of their advanced production capacity toward high-bandwidth memory (HBM) for AI applications.1 This reallocation has squeezed the supply of consumer-grade DRAM and SSD production, while GDDR memory used in graphics cards has become increasingly constrained. Graphics card manufacturers now face significantly higher memory costs—8GB card memory expenses have increased by approximately 76 dollars, 12GB by 114 dollars, and 16GB by 152 dollars.2 Multiple graphics card listings have been temporarily removed from e-commerce platforms including JD.com.2 Industry observers widely expect these price increases to potentially extend through 2027.1
