Intel on esitellyt uuden neuromorfisen prosessorijärjestelmän, joka kykenee prosessoimaan tekoälylaskentaa jopa 1000 kertaa tavallista mikroprosessoria nopeammin. Lisäksi suoritin tunnistaa esimerkiksi graafeja 10000 kertaa energiatehokkaammin kuin tavalliset PC-prosessorit.

Innoituksen suorittimien nimeämiseen Intel on ottanut Havaijilta. Järjestelmän perusprosessoriyksikkö on nimeltään Loihi ja kun näitä suorittimia liitetään kahdelle kortille 64 kappaletta, saadaan Pohoiki Beach -järjestelmä.

Intel Labsin johtaja Rich Uhligin mukaan Pohoiki Beachia käytetään ennen kaikkea tutkimuslaitoksissa. Sen avulla voidaan ratkaista erilaisia raskaan laskennan ongelmia. Esimerkiksi Uhlig nostaa vaikkapa jalkaproteesin, joka osaa reagoida tienpinnan epätasaisuuksiin. Normaalilla CPU:lla tämä onnistuisi myös, mutta selvästi tehottomammin.

Pohoiki Beach -kortilla on yhteensä 8 miljoonaa laskentayksikköä, jotka vastaavat ihmisaivojen neuronia. Intel aikoo jo tämän vuoden loppuun mennessä skaalata järjestelmän 100 miljoonaan neuroniin.

Intelin neuroprosessori osoittaa, että kun perinteisiä suoritinarkitehtuureja on vaikea skaalata tehokkaammiksi Mooren lain hengessä, uusilla arkkitehtuureilla päästään huimiin parannuksiin. Loihi-piiri yltää esimerkiksi syväoppimistesteissä 109 kertaa pienempään tehonkulutukseen, kuin kaupallisissa sovelluksissa nyt käytössä olevat GPU-prosessorit.
