内存厂商Micron美光在第一天的VTF2003（威盛技术论坛2003）大会上展示了搭载GDDR3内存的NV40和R420显示卡样品。首先展示的是nVIDIA下一代主力图形芯片NV40的显示卡样品，搭载256MB GDDR3 800MHz显存，显存带宽51.2GB/s，规格8Mbx32。可以看到，NV40图形芯片采用类似于Athlon 64移动处理器的封装，褐色基板上是NV40内核，周围有一圈电阻。根据VTF2003大会现场的消息，NV40显示卡零售版本，最早将在11月或者12月上市。Micron GDDR3内存芯片工作电压是1.8V，并且GDDR3显存发热量不大，不需要专门的散热片。ATi的R420显示卡样品，还处于设计阶段，没有输出接口，芯片表面的代号是VIPER，出厂日期非常新，是今年37周，也就是几天前的样子。
