ATI Rialto
Rialto is a bridge chip developed by ATI Technologies , which enables the use of PCI-Express graphics processors in connection with the Accelerated Graphics Port (AGP). It was named after the Rialto Bridge in Venice . High-Speed Interconnect from Nvidia has a similar purpose .
technology
The chip converts the signal from AGP into a PCI-Express signal, which is then passed on to the graphics processor . However, since the PCI Express graphics interface is faster than the AGP interface, this can result in a loss of performance if a higher data transfer rate would be useful. This is especially the case with graphics cards with relatively little graphics memory .
history
The Rialto chip was first used in 2005 in graphics cards with Radeon GPUs from the ATI Radeon X series in order to be able to offer models for AGP based on them. The board partners were responsible for deciding which cards were equipped with this chip. In the first generation, the chip was still used in most models. However , it was only used sporadically in the following ATI Radeon X1000 series . The last time the Rialto chip was used was in the ATI Radeon HD 4000 series from 2008.
