瑞芯微RK3288最强GPU技术细节深度分析Yesky数码影像频道2014-04-20 09:38分享到：我要吐槽2014年香港电子展，瑞芯微盛大发布了堪称跑分王、游戏王、超清王的RK3288处理器。

该处理器采用MALI T764(ARM产品序列为T760)GPU，为当前ARM MALI序列最高规格。

在性能上极为强悍，下文对RK3288 GPU性能进行全面分析。

一、GFXBench表现神勇中国芯首入TOP3排名根据现场媒体实测数据显示，RK3288采用的MALI T764 GPU，在GFXBench获得TOP3性能排名，仅次于苹果A7 GPU与Adreno 300。

这也是中国芯首次进入GFXBench TOP3排名，表现极为神勇。

在国产芯史上最强跑分结果的背后，有RK3288 GPU全新的AFBC( ARM Frame Buffer Compression)、ASTC( Adaptive Scalable Texture Compression)、TE(Transaction Elimination)三大技术支撑与全新图像引擎之功。

现场，瑞芯微还展示了基于RK3288的超高清平板;基于RK3288，无需外挂高清屏驱动芯片，3288就可以运行4K×2K的超高清屏幕。

至此，RK3288是目前市面唯一一颗支持所有分辨率屏幕的芯片。

另外，瑞芯微还展示了采用RK3288处理器的盒子产品，支持H.265硬解、完美支持4K输出及HDMI2.0三大特性极具看点。

二、先进内存压缩技术RK3288 GPU成全球首款4Kx2K 硬解H.265处理器视频和图形是内存带宽的消耗重点。

随着分辨率的不断提高(720P、1080P、2560*1920、2K、4K),内存带宽压力越来越大，但任何减少内存带宽的技术都会同时提高功耗。

因此与桌面GPU动辄256bit甚至384bit的位宽、1.2-1.5GHz的高频显存相比，手持设备通常搭配RAM 的是低功耗、窄带宽的LPDDR 、LPDDR2 等特殊内存——普遍使用的是双32bit位宽、LPDDR2-800或1066左右的内存系统，总带宽普遍在10GB/s以内。
