Colleagues recently managed more closely communicate with the PCI-SIG, and they explained that the new PCI Express 4.0 standard does not only raise the speed of information exchange to 16 gigahertz per second, but also significantly increase the transmitted through the expansion slot motherboard power board - from the current 75 W to 300 W, at a minimum. The working group discussed the possibility of limiting the transmitted power at 400-500 W.
Nevertheless, even the "minimum" of 300 watts is enough for such powerful modern graphics cards, like NVIDIA Titan X. additional power connector such giants with the transition to PCI Express 4.0 is not required. However, with the advent of the new features of graphics solutions for certain developers will take advantage of them.
Along the way, will develop interface OCuLink , which is the third consecutive year, is trying to become a universal solution for connecting external hard drives and video cards. PCI Express 4.0 specification may be approved by the end of this year.
