Katin bidiyo na AMD ya sake zama jagora a cikin hakar ma'adinai na Ethereum cryptocurrency. Radeon VII mai haɓaka zane-zane na flagship Radeon VII ya sami damar haɓaka katunan bidiyo na baya dangane da Vega, da Radeon Pro Duo dangane da Fiji GPUs guda biyu, har ma da shugaban da ya gabata - NVIDIA Titan V dangane da Volta.
Katin bidiyo na Radeon VII daga cikin akwatin, wato, ba tare da wani gyare-gyare ko canje-canje ba, yana iya samar da gudun ma'adinai na 90 Mhash/s. Wannan kusan sau uku aikin Radeon RX Vega 64 ne daga cikin akwatin, kuma 29% ya fi na Radeon Pro Duo. Bambanci da Titan V shima yana da mahimmanci - katin bidiyo na NVIDIA yana da ikon samar da hashrate na 69 Mhash/s a daidaitaccen tsari.
Yin amfani da magudi daban-daban tare da sigogi, zaku iya ƙara hashrate na katin bidiyo na Radeon VII har zuwa 100 Mhash/s. Koyaya, zai zama mafi kyawu don rage yawan amfani da wutar lantarki daga 319 zuwa 251 W, yayin da yake rufe ƙwaƙwalwar ajiya daga 1000 zuwa 1100 MHz, kuma yana tilasta GPU yayi aiki akan ƙarfin lantarki na 950 mV a mitar 1750 MHz. A karkashin irin wannan yanayi, yawan samarwa zai zama 91 Mkhesh / s, kuma yadda ya dace zai karu da 21%.
Tabbas, don sauran katunan bidiyo, ta amfani da ingantawa kuma zaku iya cimma haɓakar hashrate. Misali, don Titan V, ingantawa yana ba mu damar isa 82Mhash/s. Bi da bi, Radeon RX Vega 64 yana da ikon "mining ether" a gudun 44 Mhash/s. Hakanan yana da kyau a lura cewa don katunan bidiyo na NVIDIA GeForce GTX 1080 da GTX 1080 Ti akwai facin software na musamman waɗanda ke ba da haɓakar haɓakar hashrate zuwa 40 da 50 Mhash, bi da bi, ko ma sama da haka. Wannan kuma yana rage amfani da makamashi.
Idan aka kwatanta da Titan V, sabon Radeon VII ba kawai yana da babban aiki ba, har ma yana da farashi mai ban sha'awa - katunan bidiyo sun kai $ 3000 da $ 700, bi da bi. Idan aka kwatanta da sauran masu haɓaka zane-zane, Radeon VII ya fi ƙarfin aiki da yawan kuzari. Misali, Radeon RX 570 ko RX 580 guda uku tare da hashrate kwatankwacin Radeon VII guda ɗaya zasu cinye ƙarin ƙarfi. A cikin yanayin GeForce GTX 1080 da GTX 1080 Ti, yanayin yana kama da haka: ana samar da kwatankwacin aiki tare da amfani mai ƙarfi.
Ina kuma so in zauna dabam a kan inda irin wannan babban bambanci tsakanin Radeon RX Vega 64 da Radeon VII ya fito. Ya shafi ƙwaƙwalwar ajiya da bandwidth ɗin sa. Yayin da Radeon RX Vega 64 yana da 8 GB HBM2 tare da bandwidth 484 GB/s, sabon Radeon VII yana da 16 GB HBM2 tare da bandwidth 1 TB/s. A lokaci guda, ikon amfani da katunan bidiyo yana kusan a matakin iri ɗaya, wanda ya sa Radeon VII ya zama mafita mai ban sha'awa don hakar ma'adinai.
Duk da haka, akwai hasashe a bayyane a nan: ribar ma'adinai a halin yanzu ba a matsayi mafi girma ba, kuma ko da tare da irin wannan babban hashrate, yana da wuya cewa zai yiwu a sami babbar riba ta amfani da Radeon VII. Idan da wannan katin bidiyo ya kasance shekara daya da rabi da suka wuce...
