Radeon 256

The first-generation Radeon GPU was launched in 2000, and was initially code-named "Rage 6", (later "R100"), as the successor to ATI's aging Rage 128 which was unable to compete with the GeForce 256. The Radeon was comparable in specification to the nVidia GeForce2. The Radeon and GeForce differed with regards to their pixel pipeline configuration. The GeForce2 line had a maximum throughput of 4 pixels written to the frame buffer per clock cycle, and could sample two different texture maps per pixel (a so-called "4x2" configuration). The Radeon had a pixel processing throughput of two pixels per clock (having two pixel pipelines), but could sample from three separate texture maps (having three Texture Mapping Units) in a single clock (a "2x3" configuration), which was initially ATI's definition of a Radeon; a graphics processor which, among other things (DirectX 7 T&L, etc), had 3 TMUs. Unfortunately, the third texture unit did not get much use in games during the card's lifetime. The ATI Radeon also introduced a new technology called HyperZ, which improved the efficiency of the method used to remove obscured objects from the rendering pipeline, generally adding an effective 30% more bandwidth.

In terms of texel and pixel throughput, the Radeon scored lower than the GeForce2 in most benchmarks, even with HyperZ activated. The performance difference was especially noticeable in 16-bit color, where both the GeForce2 and 3dfx's Voodoo 5 5500 were far ahead. However, the Radeon could close the gap and even overtake the GeForce2 in 32-bit color, which became the standard for games onward from 1999. Although the Radeon was plagued by poor drivers, it was considered a better well-rounded card with superior DVD-playback and environment-mapped bump mapping, features that the gamer-oriented GeForce series lacked.

Aside from the new 3D-core, the Radeon introduced per-pixel video-deinterlacing to ATI's already leading-edge HDTV-capable MPEG-2 engine. In motion-video applications ranging from AVI to DVD playback, the Radeon was considered by many to be in a class by itself. (But due to the immaturity of device drivers and the DirectX-VA software API, the deinterlacing was only used by one application: Ravisent Cinemaster DVD.)

The first versions of the Radeon (R100) were the Radeon DDR, available in Spring 2000 with 32MB or 64MB configurations; the 64MB card had a slightly faster clock speed and added VIVO (video-in/video-out) capability. Initially called the Radeon 256, its name was changed before release in order to avoid any confusion with the GeForce 256; the new Radeon cards were meant to surpass them, not compete with them. The slower and short-lived Radeon 32MB SDR was added in summer 2000 to compete with the GeForce2 MX. In 2001, after the release of the Radeon 8500, the original Radeon model (R100) was renamed as the Radeon 7200. The 7200 was first used to market the short-lived (R100) 64MB SDR card that was released in summer 2001, but it was later applied retroactively to include all R100 chips regardless of memory configuration.

Other models of the first-generation Radeon were the Radeon VE (RV100), later known as the Radeon 7000), which was a cost-reduced model. The VE lacked much of the original Radeon's 3D-hardware: one pixel-pipeline, HyperZ, and Hardware T&L were all removed, as well as a 64-bit memory bus, although it added "Hydravision" dual-monitor support and integrated a 2nd RAMDAC into the core (for "Hydravision"). Despite dual-monitor support, the VE did not fare well against the T&L capable GeForce2 MX, although the VE came out ahead in DirectX and 32-bit color support. The Radeon VE was later used as the follow-up for the Mobility Radeon which proved more successful in the laptop market.

DirectX is a collection of APIs for easily handling tasks related to game programming on Microsoft Windows. ...


In 2000, around the release of the Radeon SDR, another model was the OEM-only Radeon LE, a "crippled" card made by a third-party from Radeon chips that did not meet specifications. It was however almost a full blown Radeon (R100) 32MB DDR, albeit with reduced clock frequency and HyperZ disabled at the software level; these handicaps could be overcome through overclocking and enabling HyperZ in the Windows registry. Tweaking the Radeon LE allowed it to closely match the performance of ATI's Radeon 32MB DDR and thus the LE was a bargain at half the price of the original. OEM is an acronym for either of the following: Original Equipment Manufacturer Office of Emergency Management. ... In computing, the Windows registry is a database which stores settings and options for the operating system for Microsoft Windows 32-bit versions. ...


The final model was the Radeon 7500 (a.k.a. RV200), which was based on a 0.15 micrometer (150nm) manufacturing process (R(V)100 used a 0.18 micrometer process) and clocked considerably higher than the "R100". It was basically a "R100" with a die shrink and higher clocks, running 290MHz core and 230MHz RAM. One of the tweaks to the chip was to allow asynchronous clock operation, whereas the original "R100" was always clocked synchronously with its RAM. It was also ATI's first T&L chip that included dual-monitor support (Hydravision). Launched in fall 2001 alongside the Radeon 8500, the 7500 was intended to compete with the GeForce2 Ti and GeForce2 MX in the way that the 8500 was supposed to compete with the Ti500. When nVidia launched the GeForce4 family in early 2002, the Radeon 7500's performance was inferior to nVidia's similarly-priced GeForce4 MX440. This led ATI to release its successor, the Radeon 9000. However, the Mobility Radeon 7500 was highly successful as a laptop graphics solution since it easily outperformed the GeForce2 Go and it took a while before the GeForce4 Go (laptop GeForce4 MX) was released.

The original Radeon (R100) products (32MB DDR and 64MB DDR) was never renamed 7200 throughout its production life. In summer 2001 when the Radeon 7200 was introduced (R100 with 64MB SDR), ATI continued to sell the Radeon DDR line alongside and maintain the original product name. Since 2002, ATI's CATALYSTâ„¢ drivers will recognize all R100 chips as Radeon 7200 regardless of memory configuration.


After 2001, ATI and its third party graphics card manufacturers discarded SDR (single data rate) VRAM. VRAM an acronym for Video RAM. Generally a term used in computers to describe RAM dedicated to the purpose of displaying bitmap graphics in raster graphics hardware. ...
