Key Takeaways
- GPUs zoo li cov tsheb npav: qeeb dua li cov tsheb kis las, tab sis zoo dua ntawm kev hloov ntau tus lej sib npaug.
- GPUs yog siv rau hauv kev kawm tshuab, tshuaj, ua duab, thiab ua si.
- Intel's Iris Xe Max yog tsim los ua kom lub laptops muaj zog dua rau cov tsim thiab AI.
Intel's tshiab Iris Xe Max Graphics Processor Unit tam sim no tau tshwm sim hauv laptops, thiab los ntawm txhua tus account nws yog qhov loj. Tab sis dab tsi yog GPU, thiab vim li cas nws tseem ceeb? Spoiler: Nws tsis yog hais txog kev ua si, lossis txawm tias cov duab.
CPU hauv koj lub computer, ib qho uas ua haujlwm ib hnub dhau ib hnub, kim, thiab tshwj xeeb heev. Ib qho GPU, ntawm qhov tod tes, yog qhov zoo tiag tiag ntawm lej. Tshwj xeeb, lawv tuaj yeem sib ntxiv cov lej loj, thiab lawv tuaj yeem ua tau ntau, ntau yam haujlwm ua ke. Qhov no ua rau lawv zoo rau tsim cov duab 3D nyuaj, tab sis lawv tau siv ntau ntxiv.
"GPUs yog qhov zoo rau cov ntaub ntawv loj, kev kawm tshuab, thiab ua cov duab," 3D animator David Rivera hais rau Lifewire ntawm cov lus tam sim. "Kuv muaj ntau tus npoj yaig uas siv nws hauv tshuaj kom tau txais cov txiaj ntsig MRI."
Big Math, Big Pictures
Txhua yam uas yuav tsum tau ua lej ntau yog qhov zoo tshaj plaws rau kev xa mus rau GPU.
"Graphics feem ntau muaj zog heev vim suav cov khoom 3D video nyuaj heev," Barcelona-based computer engineer Miquel Bonastre hais rau Lifewire ntawm cov lus tam sim. Tab sis tsis ntev, lub computer boffins pom tau hais tias cov tshuab lej no tuaj yeem raug nias rau hauv kev siv rau txhua yam ntawm kev ua lej ntau.
"Tam sim no, pawg supercomputing kuj tau ua nrog GPUs. Lawv tau siv rau kev suav lej, engineering, thiab lwm yam," hais tias Bonastre. Lwm qhov zoo dua ntawm GPU yog tias nws yooj yim los ntsuas. Nws tau tsim los ua haujlwm zoo ib yam nyob rau hauv tib lub sijhawm, yog li ntxiv cov chips ntau dua (lossis tsuas yog ntau cov cores rau lub nti tsim, ua kom nws loj dua) ua rau txhua yam sai dua.
A GPU kuj zoo rau kev ua cov duab. Piv txwv li, Adobe's Lightroom photo-editing suite tuaj yeem ua haujlwm rau koj lub Mac lossis PC's graphics processor los "muab kev txhim kho nrawm ntawm cov lus qhia siab," uas suav nrog 4K thiab 5K saib.
"CPUs tau ua kom zoo rau latency: kom ua tiav txoj haujlwm sai li sai tau," sau AI tus kws pab tswv yim Ygor Rebouças Serpa. "GPUs yog optimized rau throughput: lawv qeeb, tab sis lawv ua hauj lwm ntawm tej ntaub ntawv ib zaug." Serpa piv CPU rau lub tsheb kis las, thiab GPU rau lub tsheb npav. Lub tsheb npav qeeb qeeb, tab sis nws tuaj yeem hloov tau ntau tus neeg.
Koj Tus Xov Tooj Dab Tsi?
GPU hauv koj lub xov tooj yog siv los tsav nws cov kev daws teeb meem super siab, thiab khiav cov duab. Tias yog vim li cas lub xov tooj tau kub thaum koj ua si-tus GPU ncaws hauv, thiab koj lub xov tooj tsis muaj kiv cua kom txias.
Nyob ntawm iPhone, GPU yog siv rau kev paub txog cov duab, kev kawm lus ntuj, thiab kev tshuaj xyuas cov lus tsa suab. Ntawd yog, nws ua cov duab thiab yees duab thaum koj tua lawv, thiab ntau dua.
GPUs yog qhov zoo rau cov ntaub ntawv loj, kev kawm tshuab, thiab ua cov duab.
Tab sis tsis yog tag nrho. Apple's iPhones thiab iPads tsis ntev los no muaj "Neural Engine." Qhov no yog lub nti loj, tshwj xeeb uas tsim los ua cov haujlwm ntawm kev kawm tshuab. Nws tsis yog GPU, tab sis nws yog GPU-zoo li hauv lub tswv yim, nyob rau hauv uas nws crunches nyuaj lej teeb meem nyob rau hauv tsis muaj sij hawm txhua. Qhov tseeb version yog, raws li Apple, "muaj peev xwm ua tau txog 11 trillion kev ua haujlwm ib ob."
Machine Learning
Tej zaum lo lus nrov tshaj plaws hauv kev suav tam sim no yog "kev kawm tshuab." Qhov no suav nrog kev qhia lub computer ntau yam piv txwv, thiab cia lub computer ua haujlwm tawm qhov sib xws thiab qhov sib txawv. GPUs yog qhov zoo tshaj plaws rau qhov no vim tias lawv tuaj yeem saib ntau cov piv txwv ib ob. Txawm li cas los xij, thaum qhov kev cob qhia ua tiav, GPU tsis xav tau lawm. Txhua qhov kev kawm algorithms tuaj yeem khiav nrawm dua los ntawm CPU.
Tam sim no, cia peb rov qab mus rau Intel tus tshiab Iris Xe Max GPU. Qhov no yog tsim los rau kev khiav hauv "nyias-thiab-lub teeb lub laptops thiab [rau] hais txog qhov loj hlob ntawm cov neeg tsim khoom uas xav tau kev txav mus los ntau dua," Intel Tus Lwm Thawj Coj Roger Chandler tau hais hauv nqe lus. Ntawd yog, nws txhais tau tias yuav ua kom lub zog-txheej laptops zoo dua rau kev kho video, duab, thiab lwm yam kev ua haujlwm GPU-intensive. Yog, suav nrog AI.
The Iris Xe Max yog tsim los rau kev kawm tshuab. Tej zaum nws thawj txoj hauj lwm yuav yog kawm kom hais nws lub npe.
