桥片的显示单元从多方信息看，有几个关键词，统一渲染架构，4倍抗锯齿，OpenGL2.1，视频输出接口统一成 HDMI 1.4b，gpu能力等效AMD HD3200，基本上可以替换亮机卡，桌面能达到1080P FULL流畅不卡顿。
另外值得一提的是，虽说是桥片内置显卡，整体上还是独显架构，GPU运算集中在单独的DDR4显存里，通过DMA和内存交换数据。如果显示单元满负荷，再加上4倍抗锯齿，7A2000的散热需要强化，出来的板子就要留意一下桥片散热了，当然也要留意主板上显存的大小，128MB太小了！，目前看到的7A2000主板，显存都是1GB！
新增：
着色器64个，工作频率500MHZ
显存：DDR4 2400MHZ
从手册信息看，单路的u+7A2000，若只是普通桌面应用，能省一块亮机卡，主板上也能省下usb3.0和网卡芯片，性能整体还有+1效果，整机确实能降低成本，接口再做的丰富些，会是不错的选择！
