Which of the following expansion cards would be BEST suited for an expansion slot designed for high-bandwidth data transfer, such as video rendering or gaming applications?
Sound card with PCIe x1 interface
RAID controller expansion card with PCIe x4 interface
The correct answer is 'Graphics card with PCIe x16 interface' because PCIe x16 slots provide the highest bandwidth compared to other PCIe configurations, which makes them ideal for modern graphics cards used in video rendering and gaming where a large amount of data transfer is necessary. A PCIe x16 slot has 16 lanes that can be used for data transmission, offering multiple times the bandwidth of slots with fewer lanes. An x1 Wi-Fi card and x4 RAID controller offer lower bandwidth and are used for other purposes that do not require as much throughput.
