There are three key reasons why a PCI-E x1 graphics card can work and we’ll show you why. Today we are checking out a GeForce 7300GT that utilizes DDR-3 memory and PCI-E x1 slot. We’re going to have a look at what environments this could work in before we have a closer look at the card itself.
While we’re at it though, we will also have a look at it from a performance perspective in a low-end graphics card environment - is PCI-E x16 nothing more the marketing mumbo jumbo like AGP 8x vs. 4x (1056MB/s vs. 2112MB/s respectively) back in the day or is there actually a performance difference? Considering there is a total of 500MB/s of bandwidth (Single Data Lane - Both Directions) available on x1 slots compared to that of the huge 8000MB/s of bandwidth compared to x16 slots, it will be interesting.
