我们获悉，从近期Forceware驱动程序当中泄漏的NV48图形芯片，仅仅是NV45图形芯片的512MB显存版本，而非采用更新的图形架构。NV48核心架构和NV40相同，只是搭配的显存容量从NV40的256MB GDDR3增加到512MB GDDR3。

因此，NV48将继续沿用Geforce 6800名称，比如NV48 Ultra显示卡的正式名称将是Geforce 6800 Ultra 512MB，核心工作频率400MHz，显存工作频率1100MHz，采用桥接芯片，支持到PCI Express 16x。NV48仍然会采用GeForce 6800系列命名。目前，Gainward已经宣布了将会发布该显卡，并且其Demo将会在不久的CeBIT展会上公开。

下面就是Geforce 6800 Ultra 512MB（NV48）的泄漏照片，可以看到显示卡的辅助供电部分经过重新设计，显示卡PCB背面也集成有256MB容量的GDDR3显存芯片。
