最近，芯片领域的空气，明显有点紧。 2026 年国际消费电子展（CES）上，英伟达CEO黄仁勋在现场给出了一次非常清晰的表态：下一代基 于 Vera Rubin 架构的GPU，将不再沿用传统散热思路，而是整体切换到一套全新的方案："钻石铜复合 材料，加上45℃温水直液冷"。 一句话点名，新材料"钻石铜"，被直接抬进了高算力芯片的核心位置。 随后发生的事更耐人寻味。1月27日，河南一家钻石企业的负责人对外透露，已与黄仁勋进行过交流， 并公开展示了印有英伟达标识的"钻石铜散热样品"。虽然官方层面尚未发布任何合作声明，但圈内人心 里都有数，这种时候，往往不是空穴来风。 巧不巧，就在同一天，日本和美国也被曝出，正考虑在布局合成钻石工厂，并将其纳入数千亿美元级别 的对美投资规划之中。 于是问题来了——这类钻石新材料，真的有那么强吗？ 所谓"钻石铜"，并不是为了概念而生的噱头，而是把钻石极高的导热性能，与铜材料良好的加工性结合 在一起，正好卡住了先进封装最头疼的那个环节。 在Chiplet、CoWoS这类高密度架构中，热量一旦堆积，性能衰减和寿命损耗几乎是同步发生的。而钻 石铜的热导能力为2000W/(m·K)，可达到普 ...

Core Insights - The semiconductor industry is experiencing significant developments, particularly with Nvidia's announcement of a new cooling solution for its next-generation GPU, which incorporates a novel material called "diamond copper" [1][3]. Group 1: New Material and Technology - Nvidia's CEO Jensen Huang revealed that the next-generation Vera Rubin architecture GPU will utilize a new cooling solution combining "diamond copper composite cooling + 45°C warm water direct liquid cooling" [1]. - The "diamond copper" material merges the thermal conductivity of diamond with the ductility of copper, addressing critical challenges in advanced packaging [3][4]. - The thermal conductivity of diamond copper can exceed 2000 W/(m·K), which is five times that of pure copper, making it a vital choice for high-density packaging in various applications, including commercial aerospace, electric vehicles, AI chips, servers, and consumer electronics [4]. Group 2: Industry Position and Production - China dominates the industrial diamond market, accounting for over 90% of global production, with Henan province being a key player, particularly in the city of Zhecheng, which produces over 22 million carats annually [6]. - The development of synthetic diamonds in Zhecheng has evolved over 40 years, leading to advancements in industrial-grade and gem-quality diamonds, with significant improvements in production technology [6][8]. - Zhecheng's high-end brands, such as Zheguang, are achieving gem-quality standards comparable to traditional mined diamonds, raising the industry's quality benchmarks [8]. Group 3: Market Dynamics and Consumer Acceptance - The cost structure of Henan diamonds is reshaping global pricing, with a one-carat diamond ring from Zheguang priced under 10,000 yuan, compared to over 100,000 yuan for similar products in the traditional market [10]. - The recognition of Henan diamonds among U.S. consumers has surpassed 80%, with market share increasing from less than 15% six years ago to over 56% [12]. - Henan is not only focusing on raw material production but is also pushing for high-end customization, gaining clientele from luxury markets in the U.S., U.K., and Dubai [13].
