It should be clocked at 57 MHz. 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. However, there is a speed difference between disabled textures from start and failure to display them. The first was called 3D Rage, announced in November and some people consider it a release date as well. It supports 8-bit palettes for textures, helping to get away with small capacity. ATI went through same pain like Nvidia and 3Dlabs did in Results from TR2 were not included to the benches above because the 3D Rage cannot display textures in the game.

In following picture T stands for texturing, P for xpressiln correction, B for bilinear texture filter and Z is for Z-buffering. In came first hardware accelerated chip mach8 and one year later the first GUI accelerator mach Memory clock is reported at 57 MHz. It is noteworthy how significant is impact of perspective correction.

It offered Filtered Ratiometric Expansionwhich automatically adjusted images to full-screen size. There is some sub-pixel accuracy and hardware color calibration as well. It is the successor to the Mach series of 2D accelerators.

Archived from the original on But to my knowledge the mach64GT chip did not appear on the market until spring By using this site, you agree to the Terms of Use and Privacy Policy.


Rage LT aka Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. It does not look too bad because even speed of basic texturing is quite low.

The exception is of course special case of Su, and there the Rage xpresxion does not help the performance.

It was only evolution of the CT chip with added orthogonal hardware video overlay and scaler. All the mach64VT can do, plus improved video filtering, bus mastering and the 3d acceleration.

Flight Simulator 98 can do x without mip maps. 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. In games, performance actually suffered. In reality, early versions of the new driver only delivered increased performance in benchmarks such as Ziff-Davis ‘ 3D Winbench 98 and Final Reality. As a low-power solution with capable 2D-acceleration, the chip was used on many low-end graphics cards.

Chroma key comparison for texture transparency works. Experience Turning on mip mapping in Flight Simulator at x is a bit too much.

The processor was known for its well-performing bit color mode, but also its poorly dithered bit mode; strangely, the RAGE was not much faster in bit color despite the lower bandwidth requirements. Current technologies and software.


Summary What more to say.

Besides basic Gouraud and flat shading 3D Rage promised perspectively correct texture mapping, bilinear texture filtering, sub-pixel accuracy, depth buffering with sorting for rejection of hidden pixels, source and destination alpha blending. Rage Wti family review. Yes, there is 32 bit 3d mode, but blending operations are causing color corruption in true color depth.

What more to say. As the name says, AFR renders each frame on an independent graphics processor.

The Rage Pro graphics accelerator was the final revision of afi Rage architecture and last use of the Rage brand. There is a nice headroom in my card. For 3d games it all sounds good, with real alpha blending, fog and texture lighting support.

The first was called 3D Rage, announced in November and some people consider it a release date as well. This late chip was very similar to the Rage II and supported the same application coding. The chip was basically a die-shrunk Rage Prooptimized to be very inexpensive for solutions where only basic graphics output was necessary. Initial versions relied on standard graphics memory configurations:
