A technician is upgrading a desktop used for CAD rendering with a new high-end discrete GPU. The motherboard includes one open x16 slot, several legacy PCI slots, and a CNR riser slot. To achieve maximum graphics throughput, into which expansion slot should the technician install the card?
PCI Express (PCIe) x16 provides a dedicated, high-speed serial connection. Even the first PCIe generation delivers about 4 Gb/s in an x16 slot, and later versions are substantially faster. Conventional PCI peaks at 133 MB/s, ISA is decades old, and CNR was designed for low-bandwidth modem or audio riser cards. Therefore, a modern graphics card should always be installed in the PCIe x16 slot for the best performance.
