Khadi la kanema la AMD lakhalanso mtsogoleri pamigodi ya cryptocurrency ya Ethereum. Radeon VII wothamangitsa zithunzi zamtundu wapamwamba adatha kupitilira makadi am'mbuyomu a Vega, ndi Radeon Pro Duo kutengera ma Fiji GPU awiri, komanso mtsogoleri wakale - NVIDIA Titan V yotengera Volta.
Khadi la kanema la Radeon VII kunja kwa bokosi, ndiko kuti, popanda kusintha kapena kusintha kulikonse, limatha kupereka liwiro la migodi la 90 Mhash / s. Ndiye pafupifupi katatu kachitidwe ka Radeon RX Vega 64 kunja kwa bokosi, ndi 29% kuposa Radeon Pro Duo. Kusiyana ndi Titan V ndikofunikanso - khadi ya kanema ya NVIDIA imatha kupereka hashrate ya 69 Mhash / s pamasinthidwe okhazikika.
Pogwiritsa ntchito kusintha kosiyanasiyana ndi magawo, mutha kukulitsa hashrate ya khadi ya kanema ya Radeon VII mpaka 100 Mhash / s. Komabe, zingakhale bwino kwambiri kuchepetsa kugwiritsa ntchito mphamvu kuchokera ku 319 mpaka 251 W, ndikuwonjezera kukumbukira kuchokera ku 1000 mpaka 1100 MHz, ndikukakamiza GPU kuti igwire ntchito pamagetsi a 950 mV pafupipafupi 1750 MHz. Pansi pazimenezi, chiwerengero cha kupanga chidzakhala 91 Mkhesh / s, ndipo mphamvu idzawonjezeka ndi 21%.
Zachidziwikire, pamakadi ena amakanema, kugwiritsa ntchito kukhathamiritsa mutha kukwaniritsanso kuchuluka kwa hashrate. Mwachitsanzo, pa Titan V, kukhathamiritsa kumatilola kufikira 82 Mhash/s. Komanso, Radeon RX Vega 64 amatha "migodi ether" pa liwiro la 44 Mhash / s. Ndizofunikanso kudziwa kuti pamakhadi a kanema a NVIDIA GeForce GTX 1080 ndi GTX 1080 Ti pali mapulogalamu apadera omwe amapereka kuwonjezeka kwakukulu kwa hashrate ku 40 ndi 50 Mhash, motsatira, kapena kupitilira apo. Izi zimachepetsanso kugwiritsa ntchito mphamvu.
Poyerekeza ndi Titan V, Radeon VII yatsopano sikuti imakhala ndi magwiridwe antchito apamwamba, komanso mtengo wokongola kwambiri - makadi amakanema amawononga $ 3000 ndi $ 700, motsatana. Poyerekeza ndi ma accelerators ena ojambula, Radeon VII imachita bwino kwambiri potengera magwiridwe antchito komanso kugwiritsa ntchito mphamvu. Mwachitsanzo, atatu Radeon RX 570 kapena RX 580 yokhala ndi hashrate yofanana ndi Radeon VII imodzi idzadya mphamvu zambiri. Pankhani ya GeForce GTX 1080 ndi GTX 1080 Ti, zinthu ndizofanana: magwiridwe antchito amaperekedwa ndikugwiritsa ntchito mphamvu zambiri.
Ndikufunanso kukhala padera pomwe kusiyana kwakukulu pakati pa Radeon RX Vega 64 ndi Radeon VII kunachokera. Zonse zimatengera kukumbukira komanso bandwidth yake. Pomwe Radeon RX Vega 64 inali ndi 8 GB HBM2 yokhala ndi 484 GB/s bandwidth, Radeon VII yatsopano ili ndi 16 GB HBM2 yokhala ndi 1 TB/s bandwidth. Nthawi yomweyo, kugwiritsa ntchito mphamvu kwa makadi amakanema kumakhala pamlingo womwewo, zomwe zimapangitsa Radeon VII kukhala yankho losangalatsa kwambiri lamigodi.
Komabe, pali vuto lodziwikiratu pano: phindu la migodi silili pamtunda wapamwamba kwambiri, ndipo ngakhale ndi hashrate yapamwamba kwambiri, sizingatheke kuti pakhale phindu lalikulu pogwiritsa ntchito Radeon VII. Kukadakhala kuti khadi lavidiyoli likadakhalapo chaka ndi theka lapitalo...
