These days, Nvidia and Gigabyte, the major video card manufacturers, have been subject to a class action lawsuit by users because of the "false label" problem of the size of the GeForce GTX 970 video card, and have filed a petition to the Federal District Court of Northern California.

In the advertisement, the video card has 4GB of memory (video memory), but in fact it is a combination of 3.5GB+0.5GB. In the end, 0.5GB cannot run in full bandwidth state, which is suspected of false advertising of dummy label parameters, which has attracted dissatisfaction from American users.

Today, Huang Renxun, CEO of NVIDIA An open letter was published in, explaining why the GeForce GTX 970 graphics card can provide 4GB video memory, which is a segmented video memory access technology brought by the new Maxwell architecture. However, due to the communication problems between the technical and marketing teams, the parameters were falsely marked in the advertisements and parameter tables, indicating that similar problems would not occur again. However, our dear "Nuclear Bomb Yellow" teacher is more concerned about the great cause of providing more powerful nuclear bombs (graphics cards). The apology in the letter is not strong.
