Marketing material and the features and technical specifications sheet for the Dell Precision 7740 workstation have apparently been leaked on the Chinese website Chiphell. The new information seems to match the details in documents that were also leaked earlier this month. The Precision 7740 will offer users a choice between AMD Radeon Pro WX GPUs and Nvidia's seemingly brand-new mobile Quadro RTX GPUs.
