3D RAGE I edit

The original 3D RAGE aka Mach64 GT chip was based upon a Mach64 2D core with new 3D functionality and MPEG-1 acceleration. The 3D RAGE was released in April 1996. 1 The 3D RAGE was used in ATI s 3D Xpression video board.

The second generation Rage aka Mach64 GT-B offered roughly two times greater 3D performance. Its graphics processor was based again on a re-engineered Mach64 GUI engine that provided optimal 2D performance with either single-cycle EDO memory or high-speed SGRAM. The 3D Rage II chip was an enhanced, pin compatible version of the 3D Rage accelerator. The second-generation PCI-bus compatible chip boosted 2D performance by 20 percent and added support for MPEG-2 DVD playback. The chip also had driver support for Microsoft Direct3D and Reality Lab, QuickDraw 3D Rave, Criterion RenderWare, and Argonaut BRender. OpenGL drivers are available for the professional 3D and CAD community and Heidi drivers are available for AutoCAD users. Drivers are also provided in operating systems including Windows 95, Windows NT, the Mac OS, OS/2, and Linux. ATI also shipped a TV encoder companion chip for RAGE II, the ImpacTV chip.

RAGE II was integrated into several Macintosh Computers, including the Macintosh G3 Beige, Power Mac 6500. In IBM-compatible PCs, several motherboards and video cards used the chipset as well including: the 3D Xpression, the 3D Pro Turbo, and the original All-in-Wonder.

The 3D Rage IIc was the last version of the Rage II core and offered optional AGP support. The Rage IIc was integrated into one Macintosh computer, the original iMac G3/233 Rev. A..

Specifications for the Rage II DVD:

60 MHz core

up to 83 MHz SGRAM memory

480 MB/s memory bandwidth

ATI made a number of changes over the 3D RAGE II: a new triangle setup engine, perspective correction improvements, fog support and transparency implementations, specular lighting support, and enhanced video playback and DVD support. The 3D Rage Pro chip was designed for Intel s Accelerated Graphics Port AGP, taking advantage of execute-mode texturing, command pipelining, sideband addressing, and full 2 -mode protocols. Initial versions relied on standard graphics memory configurations: up to 8 MiB of SGRAM or 16 MB of WRAM, depending on the model.

RAGE Pro offered performance in the range of Nvidia s RIVA 128 and 3dfx s Voodoo accelerator, but generally failed to match or exceed its competitors. This, in addition to its early lack of OpenGL support, hurt sales for what was touted to be a solid gaming solution. In February 1998, ATI introduced the 2x AGP version of the Rage Pro to the OEM market and attempted to reinvent the Rage Pro for the retail market, by simultaneously renaming the chip to Rage Pro Turbo, and releasing a new Rage Pro Turbo driver-set 4.10.2312 that supposedly increased performance by 40. In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis 3D Winbench 98 and Final Reality. In games, performance actually suffered. Despite the poor introduction, the name Rage Pro Turbo stuck, and eventually ATI was able to release updated versions of the driver which granted a visible performance increase in games, however this was still not enough to garner much interest from PC enthusiasts.

The 3D Rage Pro was mainly sold in the retail market as the Xpert Work or the Xpert Play, with the only difference being a TV-out port on the Xpert Play version. It was also the built-in graphic chipset in the Sun Ultra 5/10 workstations, their first computer model to offer commodity PC hardware components.

General Specifications for the 3D Rage Pro:

75 MHz core

4, 8, and 16 MB 100 MHz SGRAM/WRAM memory

800 MB/s memory bandwidth

DirectX 6.0

Rage LT and Rage LT Pro edit

Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. This late 1996 chip was very similar to the Rage II and supported the same application coding. It integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control. The RAGE LT PRO, based on the 3D RAGE PRO, was the very first mobile GPU to use AGP. It offered Filtered Ratiometric Expansion, which automatically adjusted images to full-screen size. ATI s ImpacTV2 is integrated with the RAGE LT PRO chip to support multi-screen viewing; i.e., simultaneous outputs to TV, CRT and LCD. In addition, the RAGE LT PRO can drive two displays with different images and/or refresh rates with the use of integrated dual, independent CRT controllers. The Rage LT Pro was often used in desktop video cards that had a VESA Digital Flat Panel port to drive some desktop LCD monitors digitally.

RAGE XL edit

Rage XL was a low-cost RAGE Pro-based solution. As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards. It was also seen on Intel motherboards, as recently as 2004, and was still used in 2006 for server motherboards. The Rage XL has been succeeded by the ATI ES1000 for server use.

The chip was basically a die-shrunk Rage Pro, optimized to be very inexpensive for solutions where only basic graphics output was necessary.

RAGE 128 edit

Rage 128 AGP card

In the continuing struggle to create the fastest and most advanced 3D accelerator, ATI came up with the RAGE 128. The chip was announced in two flavors, the RAGE 128 GL and the RAGE 128 VR. Aside from the VR chip s lower price-point, the main difference was that the former was a full 128-bit design, while the VR, still a 128-bit processor internally, used a 64-bit external memory interface.

Magnum - A workstation board for OEMs with 32 MB SDRAM.

Rage Fury - 32 MB SDRAM memory and same performance as the Magnum, this add-in card was targeted at PC gamers.

Xpert 128 - 16 MB SDRAM memory and, like the others, used the RAGE 128 GL chip.

Rage Orion - RAGE 128 GL design specifically intended for Mac OS with 16 MB SDRAM memory, OpenGL and QuickDraw 3D/RAVE support, 2 essentially a market-specific Xpert 128. This card supported more and different video resolutions than later Mac-specific RAGE 128 designs. This card was targeted at Macintosh gamers.

Nexus 128 - Also a Mac-specific RAGE 128 GL design, but with 32 MB of RAM, similar to the Rage Fury. This card was targeted at graphics professionals.

Xclaim VR 128 - Also a Mac-specific RAGE 128 GL design with 16 MB SDRAM memory, but included video capture, video out, TV tuner support and QuickTime video acceleration. 2

Rage 128 was compliant to Direct3D 6 and OpenGL 1.2. It supported many features from the previous RAGE chips, such as triangle setup, DVD acceleration, and a capable VGA/GUI accelerator core. RAGE 128 added inverse discrete cosine transform IDCT acceleration to the DVD repertoire. It was ATI s first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines. The processor was known for its well-performing 32-bit color mode, but also its poorly dithered 16-bit mode; strangely, the RAGE 128 was not much faster in 16-bit color despite the lower bandwidth requirements. In 32-bit mode, RAGE 128 was more than a match for the RIVA TNT, and the Voodoo 3 did not support 32-bit at all. The chip was meant to compete with the NVIDIA RIVA TNT, Matrox G200 and G400, and 3dfx Voodoo 3.

ATI implemented a caching technique it called Twin Cache Architecture with Rage 128. The Rage 128 used an 8 kB buffer to store texels that were used by the 3D engine. In order to improve performance even more, ATI engineers also incorporated an 8 KB pixel cache used to write pixels back to the frame buffer.

Rage 128 Pro edit

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 gamer-oriented Rage Fury Pro boards and the business-oriented Xpert 2000 PRO. Rage 128 Pro was generally an even match for 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.

Alternate Frame Rendering edit

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. 3 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.

Rage 6 edit

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 codenamed Rage 6, ATI decided to rename it Radeon.

Mobility edit

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 moniker. Such chips included:

RAGE Mobility C, EC, L, M2, RAGE Pro-based Motion Compensation

RAGE Mobility P, M, M1 RAGE Pro-based Motion Compensation, IDCT

RAGE Mobility 128, M3, M4 RAGE 128Pro-based Motion Compensation, IDCT
