PowerVR SGX543MP2 vs Mali-400MP
Mali-400 MP yog GPU (Graphics Processing Unit) tsim los ntawm ARM hauv xyoo 2008. Mali-400 MP txhawb ntau qhov xwm txheej los ntawm cov neeg siv xov tooj ntawm tes mus rau smartbooks, HDTV thiab mobile gaming. PowerVR SGX543MP2 yog GPU muab los ntawm Imagination Technologies. Kev xav tau txuas ntxiv POWERVR Series5XT architecture muab lub hauv paus rau PowerVR SGX543MP2. Qhov tseeb, nws yog lawv thawj GPU siv cov qauv no.
Mali-400MP
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.
PowerVR SGX543MP2
Raws li tau hais ua ntej, PowerVR SGX543MP2 GPU yog ib qho khoom lag luam ntawm Kev Txawj Ntse. Kev xav yees duab txuas ntxiv POWERVR Series5XT architecture muab lub hauv paus rau PowerVR SGX543MP2. Lub tswv yim yees tsis ntev los no tau tso tawm ib qho tshiab ntawm SGX IP cores, uas yog raws li POWERVR Series5XT architecture, thiab PowerVR SGX543MP2 yog thawj zaug hauv kab. Tus naj npawb ntawm cov kav dej hauv PowerVR SGX543MP2 yog plaub thiab yog li nws muab kev txhim kho loj dua Series5 SGX architecture siv hauv SGX IP cores yav dhau los. Nws muab kev txhawb nqa rau kev ua haujlwm vector zoo thiab muaj peev xwm ntawm kev sib koom ua ke vim yog kev siv txuas ntxiv USSE cov lus qhia teeb tsa. Thaum PowerVR SGX543MP2 siv nrog cov ntawv thov uas yog qhov hnyav-hnyav, kev txhim kho hauv kev ua haujlwm siab li 40%. Lwm qhov kev txhim kho tseem ceeb yog nyob rau hauv qhov chaw ntawm ntab-taw tes, tshem tawm ntawm qhov chaw zais, ntau qhov piv txwv, kev tiv thaiv tus kheej, OpenVG 1.x optimizations, tuav xim qhov chaw, kho gamma. Tsis tas li ntawd, cache thiab MMU ua tau zoo dua. Kev ua tau zoo tiag tiag hauv ntiaj teb ntawm 35 lab polygons / sec thiab 1 Gpixels / sec fillrate ntawm 200MHz tau cog lus tias yuav xa los ntawm PowerVR SGX543MP2. Hais txog HD 3D cov duab, PowerVR SGX543MP2 muaj peev xwm tsav cov ntxaij vab tshaus ultra du. Raws li Imagination Technologies, 1st puas tau POWERVR SGX cov duab IP core tsim ob qho tib si ib leeg thiab ntau tus txheej txheem tau lees paub tias yog POWERVR SGX543.
Qhov txawv ntawm PowerVR SGX543MP2 thiab Mali-400MP
Mali-400 MP yog GPU tsim los ntawm ARM, thaum PowerVR SGX543MP2 yog GPU tsim los ntawm Imagination Technologies. Kev xav tau txuas ntxiv POWERVR Series5XT architecture muab lub hauv paus rau PowerVR SGX543MP2. Kev ntsuas ntsuas tau ua los ntawm anandtech qhia tau hais tias Mali-400MP yog me ntsis tom qab Nvidia's Tegra 2 hauv kev ua tau zoo thiab PowerVR SGX543MP2 tau hais tias yog 3.6 npaug sai dua Nvidia's Tegra 2. Yog li nws ncaj ncees hais tias thaum piv PowerVR SGX543MP2 thiab Mali-400MP, PowerVR SGX543MP2 outperforms Mali-400MP.
