Mali-400MP GPU vs Tegra 2
Mali-400 MP yog GPU (Graphics Processing Unit) tsim los ntawm ARM hauv xyoo 2008. Mali-400 MP txhawb kev siv ntau yam los ntawm cov neeg siv xov tooj ntawm tes mus rau smartbooks, HDTV thiab mobile gaming. Tegra 2 yog System-on-Chip tsim los ntawm Nvidia rau cov khoom siv txawb xws li cov xov tooj ntse, tus pab cuam tus kheej, thiab cov khoom siv hauv Internet. Nvidia thov tias Tegra ™ 2 yog thawj lub xov tooj ntawm tes dual-core CPU thiab yog li nws muaj peev xwm ua haujlwm ntau heev.
Mali™-400 MP
Mali ™-400 MP yog lub ntiaj teb thawj OpenGL ES 2.0 conformant multi-core GPU. Nws muab kev txhawb nqa rau vector duab los ntawm OpenVG 1.1 thiab 3D duab los ntawm OpenGL ES 1.1 thiab 2.0, yog li muab cov duab ua kom nrawm nrawm raws li cov qauv qhib. Mali-400 MP yog scalable los ntawm 1 mus rau 4 cores. Nws kuj muab AMBA® AXI interface kev lag luam tus qauv, uas ua rau kev sib koom ua ke ntawm Mali-400 MP rau hauv SoC tsim ncaj nraim. Qhov no kuj tseem muab lub ntsiab lus txhais tau zoo rau kev txuas Mali-400 MP rau lwm lub tsheb npav. Tsis tas li ntawd, Mali-400 MP muaj qhov programmable tag nrho uas muab kev txhawb nqa kev ua haujlwm siab rau ob qho tib si shader-based thiab tsau-function graphics APIs. Mali-400 MP muaj ib pawg tsav tsheb rau txhua qhov kev teeb tsa ntau yam, uas ua kom yooj yim rau daim ntawv thov porting, kev sib koom ua ke thiab kev saib xyuas. Cov yam ntxwv muab los ntawm Mali-400 MP suav nrog cov pobzeb-raws li kev ncua sijhawm ua haujlwm thiab hauv zos buffering ntawm nruab nrab pixel lub xeev uas txo cov cim xeeb bandwidth nyiaj siv ua haujlwm thiab lub zog noj, ua kom zoo alpha sib xyaw ntawm ntau txheej hauv kho vajtse thiab Full Scene Anti-Aliasing (FSAA) siv cov kab sib hloov. multi sampling uas txhim kho cov duab zoo thiab kev ua tau zoo.
Nvidia Tegra™ 2
Raws li Nvidia, Tegra ™ 2 yog thawj lub xov tooj ntawm tes dual-core CPU uas muaj peev xwm ua haujlwm ntau heev. Vim li no, lawv thov tias nws tuaj yeem muab ob zaug kev tshawb nrhiav sai dua, kho vajtse nrawm dua Flash thiab console-zoo gaming nrog NVIDIA® GeForce® GPU. Cov yam ntxwv tseem ceeb hauv Tegra ™ 2 yog Dual-core ARM Cortex-A9 CPU uas yog thawj lub xov tooj ntawm tes CPU nrog kev ua tsis tiav. Qhov no muab kev tshawb xyuas lub vev xaib sai dua, lub sijhawm teb ceev heev thiab kev ua haujlwm zoo dua. Lwm qhov tseem ceeb tshaj plaws yog Ultra-low zog (ULP) GeForce GPU, uas muab cov kev ua si zoo tshaj plaws hauv 3D kev ua si thiab ua kom pom kev zoo, ua haujlwm zoo 3D cov neeg siv nrog kev siv hluav taws xob tsawg heev. Tegra ™ 2 kuj muaj 1080p Video Playback Processor uas tso cai rau saib 1080p HD tsos khaws cia ntawm lub xov tooj ntawm tes ntawm HDTV yam tsis muaj kev cuam tshuam lub roj teeb lub neej.
Qhov txawv ntawm Mali-400MP GPU thiab Tegra 2
Qhov sib txawv tseem ceeb ntawm Mali ™-400 MP thiab Tegra ™ 2 yog qhov tseeb tias Mali ™-400 MP yog GPU thaum Tegra ™ 2 yog lub xov tooj ntawm tes CPU uas muaj NVIDIA® GeForce® GPU. Muaj qee qhov kev sib piv piv txwv ua los ntawm Anandtech, ntawm Tegra ™ 2 thiab Exynos 4210 uas nta Mali-400 MP GPU. Exynos 4210 yog SoC raws li 32-ntsis RISC processor tsim rau cov xov tooj ntse, ntsiav tshuaj PCs thiab Netbook kev lag luam. Cov qauv ntsuas no suav nrog SunSpider Javascript benchmark 0.9, GUIMark2 - mobile vector charting test rau flash performance thiab GLBenchmark 2.0 - pro. Cov kev ntsuas ntsuas no qhia tau tias Tegra 2 ua tus thawj coj dhau Exynos hauv yuav luag txhua pawg. Tshwj xeeb, qhov no yog qhov tseeb tshwj xeeb rau kev ua si mobile.
