http://www.theinquirer.net/?article=14739 对岸的网站的新闻 根据Thinquirer报道，ATi R420正式名称是R420XT或者R420Pro。R420图形芯片将内建12条 象素渲染管线。R420是R360图形芯片经过超级优化的产物，采用0.13微米制程，工作频率 高於R360图形芯片的上限412MHz。之前有报道表示，XT版本的R420工作频率是500/1GHz，采 用GDDR3显存，发热量比GDDR2显存更少。R420图形芯片内建6个顶点着色单元，提供强大顶点 处理能力 -----原文 ATi's upcoming R420 to sport 12 pipelines Marchitectural miracles By Fuad Abazovic: 星期一 15 三月 2004, 14:17 THE BIGGEST and most closely-guarded secret about ATI's upcoming R420 chip, in either R420XT or R420PRO guise, is the number of pipelines the chip will use. But now we can reveal that the R420 design features 12 working piplines from a possible maximum of 16. The ATI R420 chip seems to be a heavily-tweaked R360 core, with added pipelines , built on a .13 marchitecture that allows the chips to run faster than ATI's current high-end chip milestone, a 412MHz R360. As we previously said, the relative frequency numbers for this chip will be close to 500/1000MHz in its XT version; it will use GDDR 3 memory that consumes less power, and yet gives out less heat, than DDR 2. Its all about the brawn this time, ATI says. And, with six vertex shader units, this chip ought to be very fast. Despite protests, the outlook remains very cloudy for the upcoming performance crown battle between the R420 and Nvidia's NV40. μ --
