在NVIDIA和ATI两强相争的独立显卡市场中,在任何一个价格段上,双方的产品都在互不相让地激烈竞争着。为了应对ATI RADEON X1600系列在中端市场的挑战,NVIDIA推出了GeForce 6600 DDR2版。除了版本中说明的 DDR2内存之外,它还将GeForce 6600标准版过低的标准频率作了一定的调整,其标准核心／显存频率被设定为400MHz／800MHz。重要的是它在升级之后仍保持着价格的不变,丽台推出的PX6600TD 256战斗版就是一款基于GeForce 6600 DDR2的产品,其报价仍然保持在千元以下。 In the discrete graphics market where NVIDIA and ATI are competing against each other, the products on both sides are fiercely competitive with each other at any price stage. In response to the ATI RADEON X1600 series in the mid-market challenges, NVIDIA introduced the GeForce 6600 DDR2 version. In addition to the DDR2 memory described in the release, the standard frequency of the GeForce 6600 Standard is adjusted too low. The standard core / memory frequency is set to 400MHz / 800MHz. The important thing is that after the upgrade, it maintains the same price. The PX6600TD 256 combat version launched by Leadtek is a GeForce 6600 DDR2-based product whose quotation is still below RMB1,000.
