GPU vs TPU fun AI
Awọn GPUs ati awọn TPU jẹ awọn oriṣi chirún ti o ni agbara meji fun ikẹkọ ati ṣiṣiṣẹ AI.
Akopọ
GPUs are flexible all-rounders dominated by NVIDIA; TPUs are Google's custom chips built specifically to crunch the math behind neural networks.
Jin Dive
GPU kan (Ẹka Ṣiṣẹda Awọn aworan) ni ipilẹṣẹ lati ṣe awọn aworan ere fidio, ṣugbọn ẹgbẹẹgbẹrun awọn ohun kohun ti o jọra ni o jẹ pipe fun matrix matrix ni ikẹkọ jinlẹ. Awọn GPUs NVIDIA (bii A100 ati H100), so pọ pẹlu ilolupo sọfitiwia CUDA, di aiyipada ile-iṣẹ naa. TPU kan (Ẹka Processing Tensor) jẹ Google's ASIC - chirún kan pato ohun elo ti a ṣe apẹrẹ lati ibere fun awọn iṣẹ tensor. Awọn TPU lo 'systolic array' ti o nṣan data nipasẹ akoj ti isodipupo awọn ẹya pẹlu ijabọ iranti iwonba, ṣiṣe wọn daradara pupọ fun awọn isodipupo matrix nla. Iṣowo ti o wulo: Awọn GPU wapọ, wa ni ibigbogbo, ati atilẹyin nipasẹ ilolupo sọfitiwia nla kan; Awọn TPU le funni ni iṣẹ ṣiṣe to dara julọ-fun-watt ati idiyele fun ikẹkọ iwọn-nla kan pato ṣugbọn a so pọ si Google Cloud ati akopọ TensorFlow/JAX.
Imọ-imọ-ẹrọ
Iyatọ akọle jẹ faaji. GPU kan ni ọpọlọpọ awọn ohun kohun idi gbogbogbo pẹlu amọja 'Tensor Cores' fun matrix matrix. TPU ti wa ni itumọ ti ni ayika eto systolic kan: akoj ohun elo nibiti data ti nṣàn nipasẹ awọn ẹya isodipupo ti o ni asopọ pọ, nitorinaa awọn abajade agbedemeji kọja taara laarin awọn sẹẹli dipo kika nigbagbogbo ati iranti kikọ. Eyi ge gige bandiwidi iranti ni iwọn titẹ bandiwidi - nigbagbogbo igo gidi - ṣiṣe awọn TPUs daradara ni matrix ipon pupọ ti o jẹ gaba lori ikẹkọ nẹtiwọọki-nẹtiwọọki.

Awọn ipinnu faaji ṣe awakọ iṣẹ ati idiyele iṣẹ fun awọn ọdun.
Awọn ipinnu diẹ sii
Ẹkọ imọ-ẹrọ ṣe iranlọwọ fun awọn ẹgbẹ lati yan akopọ to tọ, kii ṣe ọkan tuntun nikan.
Iṣakoso didara
Awọn yiyan imọ-ẹrọ to dara julọ dinku awọn iṣẹlẹ igbẹkẹle ni iṣelọpọ.
Ojo iwaju ti GPU vs TPU fun AI
Aṣa-alumọni aṣa ti wa ni isare. Ni ikọja Google's TPUs, Amazon (Trainium/Inferentia), Microsoft (Maia), ati ọpọlọpọ awọn ibẹrẹ n ṣe apẹrẹ awọn eerun AI-kan pato lati ge igbẹkẹle lori NVIDIA ati idiyele kekere. Reti amọja diẹ sii - awọn eerun lọtọ ti iṣapeye fun ikẹkọ dipo idawọle-kekere - ati tcnu ti ndagba lori iṣẹ-fun-watt bi agbara ṣe di idinamọ abuda. NVIDIA's CUDA moat jẹ ki awọn GPU jẹ gaba lori fun bayi, ṣugbọn itọsọna igba pipẹ jẹ ala-ilẹ ohun elo oniruuru diẹ sii.
Real-World imuse
Ikẹkọ awoṣe ede nla kan lori Google Cloud TPU 'pod' ti ẹgbẹẹgbẹrun awọn eerun ti o ni asopọ
Awọn oniwadi ti nlo NVIDIA H100 GPUs pẹlu CUDA lati ṣe idanwo pẹlu awọn ayaworan awoṣe tuntun
Ibẹrẹ yiyalo GPUs nipasẹ wakati lati ọdọ olupese awọsanma nitori irọrun wọn ati atilẹyin ilana gbooro
Google ti n ṣiṣẹ itọkasi fun Wa ati Tumọ daradara lori awọn TPU ni iwọn nla
Awọn ewu & Awọn ọna iṣọ
Ṣiṣepe ala-ilẹ kan le tọju awọn ailagbara eto ti o gbooro.
Awọn ohun elo amayederun ati awọn idiyele itọju nigbagbogbo ni aibikita.
Aabo ati awọn ela akiyesi le dagba bi awọn eto ṣe di eka sii.
Ilana Ilana imuse
Ṣetumo lairi, didara, ati awọn ibi-afẹde idiyele ṣaaju imuse.
Aṣepari labẹ ẹru ojulowo ati awọn ipo data.
Abojuto ohun elo fun awọn aṣiṣe, fiseete, ati ipa olumulo.
Mura ipadasẹhin pada ati awọn ipa ọna esi iṣẹlẹ ṣaaju iwọn.

What is GPU vs TPU for AI?
Awọn GPUs ati awọn TPU jẹ awọn oriṣi chirún ti o ni agbara meji fun ikẹkọ ati ṣiṣiṣẹ AI. GPUs ni o wa rọ gbogbo-rounders gaba lori nipasẹ NVIDIA; Awọn TPU jẹ awọn eerun aṣa aṣa ti Google ti a ṣe ni pataki lati fa iṣiro naa duro lẹhin awọn nẹtiwọọki nkankikan.
Kini GPU ti a ṣe ni akọkọ lati ṣe ṣaaju ki o di aringbungbun si AI?
GPUs ni a kọ lati ṣe awọn aworan, ṣugbọn apẹrẹ ti o jọra ni afiwera jẹ apẹrẹ fun matrix matrix ni ikẹkọ jinlẹ.
Tani o ṣe apẹrẹ TPU?
Ẹka Ṣiṣẹpọ Tensor jẹ chirún aṣa (ASIC) ti a ṣe apẹrẹ nipasẹ Google pataki fun awọn iṣẹ ṣiṣe nẹtiwọọki-neural.
Ohun ti mojuto hardware be mu ki TPUs daradara ni matrix isodipupo?
Awọn TPU lo eto systolic nibiti data nṣan nipasẹ akoj ti awọn sẹẹli pọ-pupọ, gbigbe awọn abajade taara laarin wọn ati idinku ijabọ iranti.
Kini ifosiwewe nigbagbogbo jẹ ọrun igo GIDI ti awọn TPU ṣe ifọkansi lati dinku?
Gbigbe data sinu ati jade kuro ninu iranti nigbagbogbo jẹ ifosiwewe idiwọn; eto systolic dinku eyi nipa gbigbe awọn abajade agbedemeji taara laarin awọn sẹẹli.
Kini anfani ilowo pataki ti awọn GPU lori awọn TPU?
GPUs wapọ, wa ni ibigbogbo, ati atilẹyin nipasẹ ilolupo CUDA ti o dagba ati atilẹyin ilana gbooro, ṣiṣe wọn jẹ aiyipada ile-iṣẹ.
