MYD-JX8MMA7开发板简单介绍

MYD-JX8MMA7 拥有2个GPU核，一个用来做3D数据处理，另一个用来做2D和 3D加速。3D GPU核支持：

• OpenGL ES 1.1，2.0
• Open VG 1.1
• 2D GPU核支持
• 多图层混合

MYD-JX8MMA7开发板具备非常强的图形处理能力,板子自带了很多测试程序,我们就来跑一跑看看。

glmark2

glmark2是开源的对OpenGL 2.0和 ES 2.0的基准测试程序，对GPU进行基准测试。glmark提供了一系列丰富的测试，涉及图形单元性能（缓冲，建筑，照明，纹理等）的不同方面，允许进行更全面和有意义的测试， 每次测试进行10秒，并且单独计算帧速率。

测试得分为252分。https://ubuntuforums.org/showthread.php?t=2131425 有一个对比数据测试得分如下：
