This page contains general information about Nvidia's GPUs and videocards based on official Nvidia specifications. ==Field explanations== The fields in the table listed below describe the following: * Model - The marketing name for the processor assigned by Nvidia. * Launch - Date of release for the processor. * Code name - The internal engineering codename for the processor (typically designated by an NVXY name and later GXY where X is the series number and Y is the schedule of the project for that generation). * 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 PCI-Express). * Memory - The amount of graphics memory available to the processor. * SM Count - Number of streaming multiprocessors.〔(【引用サイトリンク】 title=NVIDIA GeForce GTX480 Video Card Review :: Streaming Multiprocessor )〕 * Core clock - The factory core clock frequency (while some manufacturers adjust clocks lower and higher, this number will always be the reference clocks used by Nvidia). * Memory clock - The factory effective memory clock frequency (while some manufacturers adjust clocks lower and higher, this number will always be the reference clocks used by Nvidia). All DDR/GDDR memories operate at half this frequency, except for GDDR5, which operates at one quarter of this frequency. * Core config - 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. In later models, shaders are integrated into a unified shader architecture, where any one shader can perform any of the functions listed. * 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 - 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. * API support section * * DirectX - Maximum version of DirectX fully supported. * * OpenGL - Maximum version of OpenGL fully supported. * Features - Additional features that are not standard as a part of the two graphics libraries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of Nvidia graphics processing units」の詳細全文を読む スポンサード リンク
