Kadhi revhidhiyo re AMD rave zvakare mutungamiri mumigodhi yeEthereum cryptocurrency. Iyo mureza wemifananidzo inomhanyisa Radeon VII akakwanisa kupfuura ekare vhidhiyo makadhi akavakirwa paVega, uye Radeon Pro Duo yakavakirwa maviri eFiji GPUs, uye kunyangwe mutungamiri wekare - NVIDIA Titan V yakavakirwa paVolta.
Iyo Radeon VII vhidhiyo kadhi kunze kwebhokisi, kureva, pasina chero shanduko kana shanduko, inokwanisa kupa kumhanya kwemigodhi ye90 Mhash / s. Zvinenge zvakapetwa katatu kuita kweRadeon RX Vega 64 kunze kwebhokisi, uye 29% kupfuura iyo Radeon Pro Duo. Musiyano neTitan V wakakoshawo - iyo NVIDIA vhidhiyo kadhi inokwanisa kupa hashrate ye69 Mhash/s muyakajairwa gadziriro.
Uchishandisa akasiyana manipulations ane paramita, unogona kuwedzera hashrate yeRadeon VII vhidhiyo kadhi kusvika ku100 Mhash/s. Nekudaro, zvingave zvakanyanya kunaka kuderedza mashandisiro emagetsi kubva pa319 kusvika 251 W, uku uchiwedzeredza ndangariro kubva pa1000 kusvika 1100 MHz, uye kumanikidza iyo GPU kuti ishande pavoltage ye950 mV pafrequency ye1750 MHz. Pasi pemamiriro ezvinhu akadaro, chiyero chekugadzira chichava 91 Mkhesh / s, uye kubudirira kuchawedzera ne21%.
Ehe, kune mamwe makadhi evhidhiyo, uchishandisa optimizations iwe unogona zvakare kuwana kuwedzera kwehashrate. Semuenzaniso, yeTitan V, optimizations inotibvumira kusvika 82 Mhash/s. Zvakare, Radeon RX Vega 64 inokwanisa "kuchera ether" nekumhanya kwe44 Mhash / s. Izvo zvakakoshawo kuziva kuti kune NVIDIA GeForce GTX 1080 uye GTX 1080 Ti makadhi evhidhiyo kune akakosha mapeji esoftware anopa kuwedzera kwakakosha kwehashrate kusvika makumi mana uye makumi mashanu Mhash, zvichiteerana, kana kutopfuura. Izvi zvinoderedzawo kushandiswa kwesimba.
Kuenzaniswa neTitan V, iyo Radeon VII itsva haina kungoita kwepamusoro, asiwo mutengo unoyevedza - makadhi evhidhiyo anodhura madhora zviuru zvitatu nemazana manomwe emadhora zvichiteerana. Kuenzaniswa nemamwe magiraidhi anomhanyisa, Radeon VII inodarika maererano nekuita uye kushandiswa kwesimba. Semuenzaniso, matatu Radeon RX 3000 kana RX 700 ine hashrate inofananidzwa neimwe Radeon VII ichapedza simba rakawanda. Panyaya yeGeForce GTX 570 uye GTX 580 Ti, mamiriro acho akafanana: kuenzanisa kuita kunopihwa nepamusoro pesimba rekushandisa.
Ndinodawo kugara ndakaparadzana pane kwakabva musiyano mukuru wakadai pakati peRadeon RX Vega 64 neRadeon VII. Izvo zvese nezve ndangariro uye bandwidth yayo. Nepo iyo Radeon RX Vega 64 yaive ne8 GB HBM2 ine 484 GB/s bandwidth, iyo nyowani Radeon VII ine 16 GB HBM2 ine 1 TB/s bandwidth. Panguva imwecheteyo, kushandiswa kwesimba kwemakadhi evhidhiyo kunenge kune imwe nhanho, izvo zvinoita kuti Radeon VII ive yakanyanya kunakidza mhinduro yemugodhi.
Zvisinei, pane kushayikwa kuri pachena pano: purofiti yemigodhi parizvino haisi padanho repamusoro, uye kunyangwe neiyo yakakwira hashrate, hazvigoneke kuti zvigone kuita purofiti yakakura uchishandisa Radeon VII. Dai kadhi revhidhiyo iri raiveko gore nehafu rapfuura...
