The long life of R3 architecture after die shrink. ATi also never really excelled in 16 bit quality, instead they went for big true color leap ahead with next architecture. Not quite there yet, but ATi found it sufficient for years to come. They were ATI’s first graphics solutions to carry the Mobility moniker. Of course this was quickly exposed and company covered in shame.

Initial versions relied on standard graphics memory configurations: When it comes to framerates Rage Pro with same bus and memory capacity equals both minimal and average results of Voodoo Graphics.
Windows 95 and Mac OS were not supported. Final driver used for my tests is newest among everything I tried and is probably the only one with optimization for my system. The chip should support also WRAM with external MHz ramdac to exploit them at high resolutions, but I am not aware of any card taking advantage of that.

Quake 3 even has special rendering path doing this filtering in software, but in some scenarios like with teleports the Rage Pro has to do the job on its own and leave some non-interpolated texel blocks on screen. Texturing engine can now enjoy 4 kB cache, drastically reducing bandwidth demands of interpolation and enabling single pass free trilinear filtering.
Also mip mapping in advanced games like Unreal is still doing wrong mip selections, so I disabled it again. Developers were not pleased.
As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards.

From Wikipedia, the free encyclopedia. In finally qti the efforts delivered the big success, Radeona card with undisputed performance achievements and solid drivers from the start. Not quite there yet, but ATi found it sufficient for years to come.
Aside from the VR chip’s lower price-point, the main difference was that the former was a full bit design, while the VR, still a bit processor internally, used a bit external memory interface. However, Ati successfully used the “complete multimedia solution” buzz and could set attractive pricing.
The amount is about the same as for Rage II, but this time is less expected since Rage Pro was supposed to have high quality texturing engine and “free” trilinear filter will not compensate for such deficiencies. Nevertheless, sales were going strong and R3 architecture 3s to be found in newer and actually updated chips.
Finishing words The Rage Pro line may have not been warmly welcomed by gamers in retail, but strong OEM deals were feeding the company better then ever. It was ATI’s first dual texturing renderer, in that it could output two pixels per clock two pixel pipelines. They were ATI’s first graphics solutions to carry the Mobility moniker. Of course this was quickly exposed and company covered in shame. It integrated a low-voltage differential signaling LVDS transmitter for notebook LCDs and advanced power management block-by-block power control.
At the end of Radeon arrived, and while it had some performance problems in the beginning, it also showed a more advanced shading architecture than Nvidia’s. One weakness of previous Rage architecture remained- the inability to filter alpha blended textures.
The long life of R3 architecture after die shrink. It is codenamed mach64LB and as you see the chip was used for discrete cards as well. Who knows when, but the day will come when 3d accelerator as we use it will be unknown to gamers. 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.
ATI is getting faster Third generation of Rage architecture arrived in summer Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. Which brings me to gaming experience of R3 cards. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary. Actually, after two freezes doing only timedemos I am not sure if they ever really got it stable.
In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality.
