Agp 4x Cards Views
Given the timeline of the evolution of these cards, AGP 8x cards dominate todayrrs"s marketplace. Finding some cards that are backwards compatible is possible, but the tricky part may be ensuring that the slot on the motherboard will accept them. Comparing the connector on this 128MB Apollo GeForce FX6600 GT card, to the connector on this 64MB Hercules 3D Prophet Ultra II card, and to the connector on this 256MB Chaintech GeForce FX5200 card shows that the first one is obviously different than the second two. The Apollo card is 8x only, the Hercules card is 4x/2x compatible, and the Chaintech card is 8x/4x, which results in different notches in the connector.
AGP 1.0 only features a 3.3V connection, the release of AGP 2.0 saw the availability of both a 3.3V and 1.5V connector, and AGP 3.0 uses the same 1.5V, but only requires 0.8V for signaling. In order to protect cards of different voltages/formats, special keyed connectors were designed so that only the correct card could be installed on any motherboard. A universal connector was eventually released for AGP 1.0/2.0 which allowed cards of either voltage to be installed. For a schematic of the various connectors, please visit this page. Although AGP 3.0 can share in the use of a universal connection, many motherboards now only support 4x/8x cards based on the AGP 3.0 standard.
Another specification for AGP was released between 2.0 and 3.0, and was referred to as AGP Pro. AGP Pro was intended to be the new standard to meet the demands of high powered graphics workstations, but it never really garnered widespread acceptance. Speeds of 1x, 2x, and 4x were supported with AGP Pro, and it utilized either a 3.3V, 5V, or a universal connector, similar to AGP 2.0. But, the AGP Pro connector was not the same size as the tls"standard rs" AGP connector (see schematic at link above), meaning there were now three more possible connections to consider. An AGP Pro connection is longer than a standard AGP connection, and depending on the connector type, it could accept AGP 1.0 and 2.0 cards.
The AGP connector installed on many Pentiumpreg; 4 processor-based Desktop Boards is keyed for 1.5V AGP cards only.The AGP connector is not mechanically compatible with 3.3V AGP cards. To some the 1.5V AGP connector may appear backwards due to the connector key being exactly the opposite of the 3.3V AGP connector. AGP 2x/4x Universal Graphics card with AGP 1.5 Volt slotAGP 2x Graphics card with AGP 1.5 Volt slotAGP is a high-performance interface for graphics-intensive applications, such as 3D applications. While based on the AGP Local Bus Specification, Rev. 2.1, AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices.
