红杉中国投了一家想替代英伟达的中国公司

导语：天数智芯表示其GPU是从零开始开发的。

据The Information报道，红杉是一家备受瞩目的中国风险投资公司，最近与SequoiaCapital分道扬镳。根据三位知情人士的消息，红杉已经投资了一家初创公司，该公司将在中国市场与美国人工智能芯片巨头英伟达竞争。这是红杉在国内人工智能芯片初创公司方面最近值得瞩目的投资之一。

这次投资涉及的上海天数智芯，此前的投资估值已经超过了10亿美元。此次投资发生在美国试图通过出口限制，阻止中国获取英伟达生产的世界最先进芯片的前提下，这一前提为中国加快开发本土替代方案增加了紧迫性。红杉是中国最大、最成功的风险投资公司，该公司的投资行动备受其他投资者、创始人以及外国政府机构的关注。

红杉曾是Sequoia的一部分，但在分离后，美国议员对该公司在中国人工智能和芯片初创公司的投资表示担忧，担心这可能帮助中国在该领域迎头赶上美国。对于中国的风险投资公司来说，支持国内替代英伟达的公司与中国的目标相符。上周，Sequoia告诉其支持者，自己与红杉的分离已经完成，这一举措减轻了这家硅谷风险投资公司所面临的一些政治压力。

红杉投资了天数智芯，该公司开发了图形处理单元（GPU），这种芯片对于新的人工智能服务如ChatGPT等至关重要。这次投资的资本主要来自红杉的人民币基金，该基金由中国投资者投资。据知情人士称，这笔资金仅是天数智芯新一轮融资的一部分。

尽管我们无法了解红杉投资了多少金额，但根据中国媒体报道，去年天数智芯的估值已经超过了10亿美元。天数智芯的现有投资者包括得到北京和上海市政府支持的国有基金、国有电信运营商中国联通以及中国私募股权公司厚朴投资等。

天数智芯成立于2015年底，由一批半导体和软件行业的资深人士创建，其中一些曾在全球知名公司工作过，如英伟达、AMD和甲骨文。在其网站上，红杉中国表示其责任是为中国的国家战略服务。在中国，天数智芯的通用GPU芯片经过三年的开发，被认为是挑战英伟达芯片的潜在竞争对手之一。

红杉不仅支持天数智芯，还投资了其他中国GPU初创公司。在2021年初，当时被称为Sequoia Capital China的红杉，投资了上海的MetaX Tech和北京的摩尔线程，这两家公司都专注于GPU的开发。

根据PitchBook的数据，截至2022年7月，MetaX的估值为144亿元人民币（20亿美元）。而摩尔线程，及其他支持者包括国有企业以及科技巨头腾讯和字节跳动，截至2022年12月，估值为240亿元人民币（34亿美元）。

然而，摩尔线程在2022年10月面临新的挑战，美国政府出于国家安全考虑将其列入贸易黑名单。分析师表示，这么做可能是阻止与全球最大、最先进的芯片代工制造商台积电合作。

华盛顿的举措显示，人工智能芯片领域已经成为美中科技战中最激烈的战场之一。摩尔线程在2022年11月完成了新一轮融资，新的估值尚不清楚，主要投资来自中国私募股权公司，尚不清楚参与该轮融资的投资者是否在美国实施制裁之前已经承诺要参与。

目前尚不清楚中国的人工智能芯片开发有多大程度依赖国内技术。据The Information报道，摩尔线程和其他一些中国主要的GPU初创公司，如Vastai Technologies和壁仞科技，已经与总部位于英国的GPU设计公司Imagination Technologies达成了未披露的许可协议。

但是天数智芯（英文名Iluvatar在J.R.R.托尔金的小说中意为“众神之父”）没有Imagination许可的技术，该初创公司表示其GPU是从零开始开发的。该公司表示，天数智芯的GPU于2021年第三季度开始商业化，截至2022年初已产生数千万美元的订单价值。

尽管中国的GPU制造商得到了政府和私人资金的迅速支持，但提供可行的替代方案以取代英伟达并不容易。在上个月的一次采访中，著名风险投资家、去年创办了总部位于北京的AI初创公司01.AI的李开复表示，使英伟达难以取代的是其CUDA软件库周围的整个生态系统，该软件库使编程芯片变得更容易。

他说：“如果我们无法获得英伟达芯片，我们将寻找更专注于变压器的简化芯片，但这将是一个痛苦的编程过程。但如果别无选择，那我们也没有办法。”
