MYD-JX8MMA7開(kāi)發(fā)板簡(jiǎn)單介紹

MYD-JX8MMA7 擁有2個(gè)GPU核，一個(gè)用來(lái)做3D數(shù)據(jù)處理，另一個(gè)用來(lái)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
• 多圖層混合

MYD-JX8MMA7開(kāi)發(fā)板具備非常強(qiáng)的圖形處理能力,板子自帶了很多測(cè)試程序,我們就來(lái)跑一跑看看。

glmark2

glmark2是開(kāi)源的對(duì)OpenGL 2.0和 ES 2.0的基準(zhǔn)測(cè)試程序，對(duì)GPU進(jìn)行基準(zhǔn)測(cè)試。glmark提供了一系列豐富的測(cè)試，涉及圖形單元性能（緩沖，建筑，照明，紋理等）的不同方面，允許進(jìn)行更全面和有意義的測(cè)試， 每次測(cè)試進(jìn)行10秒，并且單獨(dú)計(jì)算幀速率。

測(cè)試得分為252分。https://ubuntuforums.org/showthread.php?t=2131425 有一個(gè)對(duì)比數(shù)據(jù)測(cè)試得分如下：

測(cè)試總結(jié)

通過(guò)以上眾多的測(cè)試程序可以看出MYD-JX8MMA7開(kāi)發(fā)板的3D和2D圖形性能非常不錯(cuò)，通過(guò)glmark2基準(zhǔn)測(cè)試也可以和其他芯片進(jìn)行對(duì)比，可以看到MYD-JX8MMA7開(kāi)發(fā)板處理能力甚至媲美某些桌面級(jí)的芯片。所以本開(kāi)發(fā)板也特別適合多媒體產(chǎn)品開(kāi)發(fā)，具備比較強(qiáng)的圖形處理能力。
