Later, ATI developed a successor to the original Rage 128, called the Rage 128 Pro. This chip carried several enhancements, including an enhanced triangle setup engine that doubled geometry throughput to eight million triangles/s, better texture filtering, DirectX 6.0 texture compression, AGP 4×, DVI support, and a "Rage Theater" chip for composite and S-Video TV-in. This chip was used on the game-oriented "Rage Fury Pro" boards and the business oriented "Xpert 2000 PRO". The Rage 128 Pro was generally an even match for the Voodoo 3 2000, RIVA TNT2 and Matrox G400, but was often hindered by its lower clock (often at 125mHz) when competing against the high end Voodoo3 3500, TNT2 ultra and G400 MAX. The Rage Fury MAXX board held dual Rage 128 Pro chips in an alternate frame rendering (AFR) configuration to allow a near-double increase in performance. As the name says, AFR renders each frame on an independent graphics processor. This board was meant to compete with the NVIDIA GeForce 256 and later the 3dfx Voodoo 5. While it was able to somewhat match 32 MB SDR GeForce 256 boards, the GeForce 256 cards with DDR memory still easily came out on top. Though there were few games that supported hardware transform, clipping, and lighting (T&L) at the time, the MAXX's lack of hardware T&L would put it at a disadvantage when such titles became more widespread. It was later discovered by ATI that Windows NT 5.x operating systems (Windows 2000, XP) did not support dual AGP GPUs in the way ATI had implemented them. NT put them both on the AGP bus and switched between them, and so the board could only operate as a single Rage 128 Pro with the performance of a Rage Fury card. The optimal OS for the Rage Fury MAXX is Windows 98/ME. Windows 95 and Mac OS were not supported. The Rage 128 Pro graphics accelerator was the final revision of the Rage architecture and last use of the Rage brand. While the next iteration was initially code-named "Rage 6", ATI decided to rename it Radeon (the name is still used by AMD until now, after acquiring ATI.) Rage Mobility succeeded the Rage LT and Rage LT Pro Almost every version of Rage was used in mobile applications, but there were also some special versions of these chips which were optimized for this. They were ATI's first graphics solutions to carry the "Mobility" naming Such chips included:  Original Reference Card # (RAGE 128 Pro) : 109-60600-10
