[128MB vs 256MB]

众所周知大容量的显存在处理复杂的3D场景运算时更有优势，那是因为大容量的显存能为图形处理核心提供更多的缓存空间，令图形处理核心的运行更加有效率。但256MB显存放在Radeon 9250上是否能发挥出应有的优势则令人怀疑，因为较低的核心频率有可能会负荷不起显存中大量复杂的3D场景数据，导致图形处理核心在运算过程中产生等待延迟，从而使性能提升不明显。

此次测试证实了我们对256MB显存应用在Radeon 9250上对性能提升不大的猜测，采用256MB的产品性能与128MB的相比虽相差无几，但我们从市场角度来看，256MB的产品并不比128MB的产品贵多少(只有几十元的差价)，综合来看还是有购买的价值。
