一提起3D图形加速卡,大多数人可能首先想到的是诸如:nVIDIA、3dfx、Matrox等在市场中大红大紫的芯片厂商,的确目前nVIDIA风头正劲,第六代显卡也已全面上市。绘图芯片厂商诸侯混战的局面正愈演愈烈。目前nVIDIA公司在全球发布了其最新的NV 15图形芯片,它的性能比原来的GeForce 256要快3倍左右,NV15采用了单周期4像素,双材质单像素的技术,因此在多重贴图的游戏中将可以提升近2～3倍的速度,其工作的核心频率更可达到200MHz,在T＆L(硬件转换与光影)中可提升多达45％的性能。而内存则配备了400MHz的高性能DDR显存。如此的规格造就了在运用单像素上的单材质游戏软件可以达到每秒640MB pixel的填图速率,更胜一筹的是由于NV15支持双材质单像素,故在双材质下NV15也同样拥有每秒640 MB pixel的填图速率。令人不可思议的是nVIDIA还将推出另一款128MB的NV15代号为NV15GL支持AGP4x Pro的接口,很明显,这又是一款高档图形工作站型产品。继nVIDIA的NV 15发布之后,Matrox也不甘示弱地推出了自己新一代的Matrox产品G450。最新的G450图形芯片与G400系列属于同一等级的产品。不过G450采用了0.18微米的工艺,所以散热量大大的减少了,因此在G450的显卡上不需要安装散热装置(风扇)。另外G450还集成了多种功能,如数字平板显示器的转换器(DFPT)、视频输出、副RAMDAC及64位双倍转输率(DDR)
When it comes to 3D graphics accelerator cards, most people may first think of such as: nVIDIA, 3dfx, Matrox and other popular in the market, chip makers, indeed nVIDIA limelight, the sixth generation of graphics cards have also been fully listed. Graphics chip makers princes melee situation is fierce. At present, nVIDIA released its latest NV 15 graphics chip globally. Its performance is about 3 times faster than the original GeForce 256. The NV15 uses single-cycle, 4-pixel, single-material dual-material technology, The middleman will be able to improve nearly 2 to 3 times faster, the core frequency of its work can be achieved up to 200MHz, up to 45% performance in T & L (hardware conversion and lighting). The memory is equipped with 400MHz high-performance DDR memory. Such specifications created in the use of single-pixel single-material game software can reach 640MB pixel per second mapping speed, even better because the NV15 supports dual material single pixel, so under the dual material NV15 also has the second 640 MB pixel mapping speed. It is incredible that nVIDIA will also introduce another 128MB of NV15 codenamed NV15GL support AGP4x Pro interface, it is clear that this is another high-end graphics workstation products. Following the nVIDIA NV 15 release, Matrox is also outdone to launch its own new generation of Matrox products G450. The latest G450 graphics chip and G400 series belong to the same level of product. However, the G450 uses a 0.18-micron process, so the heat dissipation is greatly reduced, so the G450’s graphics card does not require the installation of heat sinks (fans). In addition G450 also integrates a variety of functions, such as digital flat panel display converter (DFPT), video output, sub-RAMDAC and 64-bit double transfer rate (DDR)
