数字考古现场！魔改版Tesla M60现身二手市场：双芯16GB显存却不能用_我的网站

一 |     8月25日消息，近日在二手平台闲鱼上出现了一批标价400元左右的魔改版英伟达Tesla M60显卡。    A Russian court on Monday ordered a Russian-American journalist who was detained last week on charges of failing to register as a foreign agent to remain in custody until early December, her employer reported.Alsu Kurmasheva, an editor for the U.S. government-funded Radio Free Europe/Radio Liberty's Tatar-Bashkir service, appeared in a closed session in a court in the city of Kazan, the capital of the Tatarstan republic.The radio service said the court ordered her to be held until Dec. 5, rejecting her lawyer's request for preventive measures other than incarceration.She is the second U.S. journalist detained in Russia this year, after Wall Street Journal reporter Evan Gershkovich was arrested on espionage charges in March. Gershkovich remains in custody.The state-run news website Tatar-Inform said Kurmasheva faces charges of failing to register as a “foreign agent” and was collecting information on Russian military activities. Conviction would carry a sentence of up to five years in prison.Kurmasheva, who lives in Prague, was stopped June 2 at Kazan International Airport after traveling to Russia for a family emergency May 20, according to RFE/RL.Airport officials confiscated her U.S. and Russian passports and she was fined for failing to register her U.S. passport. She was waiting for her passports to be returned when the new charge was filed Wednesday, RFE/RL said.RFE/RL was told by Russian authorities in 2017 to register as a foreign agent, but it has challenged Moscow’s use of foreign agent laws in the European Court of Human Rights. The organization has been fined millions of dollars by Russia.The Committee to Protect Journalists called the charges against Kurmasheva “spurious,” saying her detention “is yet more proof that Russia is determined to stifle independent reporting.”Kurmasheva reported on ethnic minority communities in the Tatarstan and Bashkortostan republics in Russia, including projects to preserve the Tatar language and culture, her employer said.Gershkovich and The Wall Street Journal deny the allegations against him, and the U.S. government has declared him to be wrongfully detained.Russian authorities haven’t detailed any evidence to support the charges. Court proceedings against him are closed because prosecutors say details of the case are classified.。     这款被玩家戏称为会亮的墓碑的英伟达Tesla M60显卡虽然拥有双核心及总计16GB的大容量显存，但在现代软硬件环境下，其使用价值已近乎归零。          Tesla M60是英伟达在2015年针对数据中心推出的专业级渲染卡，其原生形态为典型的服务器被动散热设计，完全依赖机房高压风道带走热量。    目前市面上流通的这款400元产品，是卖家通过手工焊接三个散热风扇并包裹金属外壳魔改而成，使其能够勉强塞入普通的台式机机箱中，以维持基本的点亮运行。          硬件规格上，Tesla M60内部集成了两颗基于麦克斯韦架构的GPU核心，每颗核心拥有8GB GDDR5独立显存，整卡总显存容量达到16GB。     虽然该卡在理论上相当于两张GTX 980组建的SLI系统，但其显存池是完全分割的，GPU 0无法调用GPU 1的8GB空间。    由于英伟达早已实质性放弃了SLI多显卡协作技术，而现代的Vulkan和DirectX 12图形接口在设计时也未考虑双显卡的负载分担问题。     这意味着即便电脑能够识别两颗GPU，在大多数现代游戏中，其中一颗核心也会处于常态化闲置，导致16GB显存中有一半无法被利用。         目前这类魔改显卡的买家大多将其作为数字考古的收藏品，玩家们更倾向于研究2015年工程师如何通过双芯结构解决显存容量瓶颈，而非将其投入实际的游戏或生产力工作。    对于普通用户而言，花400元购买这样一块会亮的墓碑，其折腾成本远高于其实际收益。
