As a result, you can completely ignore speed multipliers when you're checking for compatibility between an AGP video card and an AGP motherboard. The 3.0 specification isn't as clear as the 1.0 and 2.0 specifications on the subject of requiring the lower multiplier but all AGP 3.0 implementations that I've seen support both 8x and 4x. The AGP 3.0 specification requires support for 8x.

2x and 1x support at 1.5 volts are required and 4x support is optional. The AGP 2.0 specification has a similar requirement. There is often an option in the BIOS which allows you to limit the speed to 1x if 2x is not reliable. Otherwise they run at 1x which is always implemented by all AGP 1.0 video cards and motherboards. If they both support 2x then they will run at 2x. By default, when the AGP 1.0 machine powers up it selects the fastest speed multiplier supported by both the video card and the motherboard. There's no such thing as a 3.3 volt video card or motherboard which only supports 2x. The AGP 1.0 specification requires that all implementations support the 1x speed multiplier at 3.3 volts. But it's actually much simpler than that. Looking at the various possible signaling voltages and speed multipliers, you might think that there are a large number of different kinds of video cards and motherboards supporting various combinations of voltages and multipliers.

2x is twice as fast as the base speed, 4x is four times as fast, and 8x is eight times as fast. AGP Version Signaling Voltage Peak Speeds AGP 1.0 3.3 volts 1x at 267MB/s, 2x at 533MB/s AGP 2.0 1.5 volts 1x at 267MB/s, 2x at 533MB/s, 4x at 1067MB/s AGP 3.0 0.8 volts 4x at 1067MB/s, 8x at 2133MB/s The signaling voltage is the voltage used to send data between the AGP card and the AGP motherboard. Each new version added new speeds and signaling voltages. It was followed by AGP 2.0 in 1998 and AGP 3.0 in 2002. AGP was a modified version of PCI designed to speed up transfers to video cards. There are some rare exceptions where motherboard and video card manufacturers don't obey the rules.AGP compatibility for sticklers: The Long VersionAGP Basics In 1996, Intel introduced AGP 1.0.
