Flash Player 10.1 beta GPU 加速能力测试

<Category: rayYee> 查看评论

令人期待的Adobe Flash Player 10.1已经发布了,AnandTech紧锣密鼓的对其进行了评测。对于广大用户来说,我们并不关心这个版本更新了什么功能,而是其在播放Flash时采用了GPU加速功能。现在就看一下令人兴奋的结果吧。
一、ASRock ION + Atom 330 (1.6G双核) + Vista x64 + GeForce 9300/9400M 环境下:

图表的左侧一列是采用的视频,分别是Hulu和YouTube支持的各种视频格式,包括360p、480p以及720p的视频,右侧两列分列了Flash的两种版本10.0.32.18以及10.1.51.45以窗口形式播放前面对应的视频时CPU的占用情况。

这张图表是全屏时对应的CPU占用情况。

二、AMD 785G系统(集成Radeon HD 3200) AMD Sempron LE-1150 (2GHz 单核 基于K8的CPU 二级缓存512k)环境下:

说明:上面第二个表的CPU采用的是Athlon 64×2 QL-64 双核2G的CPU,其他配置不变。第三个表代表丢帧率(越小越好),两种CPU下结果类似,第四个表中的数据采集时显卡换为Radeon HD 5850、CPU换为 Athlon II X2 240。

三、HP Mini 331 (Nvidia ION LE)环境下:

四、Gateway NV58 (Intel GMA 4500 MHD) 环境下:

五、核心测试环境为:双路16线程的3GHz Nehalem处理器的Mac Pro工作站,显卡为EVGA Geforce GTX 285,30′显示器,分辨率为2560×1600。

小提示:因为是多核系统所以CPU占用超过100%

六、补充知识

在Adobe发布的三种平台(Windows/Linux/Mac)的Flash 10.1中,只有Windows版本采用了针对使用DXVA的Flash视频文件的H.264加速。

这就意味着,你可能需要一款支持DXVA或者DXVA2的显卡来实现这种加速。Nvidia声称其G80系列以后的产品都支持此功能。最新的基于Nvidia的ION芯片组的平台是今天的测试基础。这里列一下ATi系列支持此功能的芯片:

Ati Radeon HD 4000, HD 5700, HD 5800系列

Ati移动Radeon HD 4000系列或更高

Ati Radeon HD 3000 集成显卡或更高

Ati FirePro V3750, V5700, V7750, V8700 V8750或者以后的版本

另外Intel的G45系列理论上可以支持显卡加速。但是在测试时使用的笔记本平台上并没有太好的表现。

翻译不妥的地方多提意见。

hi, i am trying to fresh format my windows vista (with a windows xp cd cus its all i have) but it doesnt work because… when i boot from the cd and unload all the files, it says ‘starting windows’ but then tells me to restart because theres probably a virus that forbids me from starting windows. and its true, theres a virus which is why im trying to reformat my computer… the virus doesnt let me do anything except buy the antivirus software, which i know it just a trick. please help… very important for what i need to do tomorrow .. oh god.. forex robot

My uncle took my computer to get it fixed after it got hit with a hard virus last year. he said there should be a virus protection on it, but i can’t find it anywher, I want to run a virus scan because something popped up telling me i have a virus. But i clicked off of it because i wasn’t sure if THAT was a virus or real. Where do I go in my computer to make sure i have a anti Virus protection, (and a fire wall) I want to download AVG to make sure, but will something bad happen if i try to download a virus protection IF i already have one that i dont know about? Thank you.
