Field explanations

The fields in the table listed below describe the following:

• Model - The Marketing name for the processor assigned by ATi
• Year - Year of release for the processor.
• Model number - Mobility Series VPUs are based on technology from several technology families. ATi assigns codenames based on an "MXX" model string, which does not relate to the actual technological base of the processor (represented by the R-number). Additionally, ATi is the sole supplier for all Mobility Radeon parts. For this reason, except for the Mobility Radeon 2000 series, all mobility processors are listed on the same table.
• Code name - The internal engineering codename for the processor (typically designated by an RNXX name where N is the series number and XX is the market segment for which the product is designed. Additionally, a codename may follow the RVNXX format where "V" typically signifies a processor intended for a mainstream or value market segment).
• Fab - Fabrication Process. Average feature size of components of the processor.
• Bus interface - Bus by which the Graphics processor is attached to the system (typically an expansion slot, such as PCI, AGP, or PCIe).
• Memory max - The maximum amount of memory used by the processor.
• Core clock max - The maximum factory core clock frequency (used as some manufacturers adjust clocks lower and higher, this number will always be that listed by ATi).
• Memory clock max - The maximum factory memory clock frequency (used as some manufacturers adjust clocks lower and higher, this number will always be that listed by ATi).
• Config Core - The layout of the graphics pipeline, in terms of functional units. Over time the number, type and variety of functional units in the GPU core has changed significantly; before each section in the list there is an explanation as to what functional units are present in each generation of processors.
• Fillrate - Maximum theoretical fillrate in Textured Pixels per second. This number is generally used as a "maximum throughput number" for the GPU and generally, a higher fillrate corresponds to a more powerful (and faster) GPU.
• Memory Subsection
  • Bandwidth Max - Maximum theoretical bandwidth for the processor at factory clock with factory bus width. GB=10^9 bytes.
  • Bus Type - Type of memory bus or buses utilized.
  • Bus Width - Maximum Bit width of the memory bus or buses utilized. This will always be a factory bus width.
• Graphics Library Support Section
  • Direct X - Highest version of DirectX with which the hardware is compliant and fully supported.
  • Open GL - Highest version of OpenGL with which the hardware is compliant and fully supported.
• Features - Additional features that are not standard as a part of the two Graphics libraries.
