Njikere AMD iwebata ezinụlọ Radeon RX 5500 nke kaadị vidiyo na October 14 bịara mara n'oge na-adịbeghị anya, mana a tụlere ihe ndabere maka ngwaahịa ọhụrụ n'ụdị nke Navi 7 ndịna-emeputa eserese ruo ogologo oge. Ugbu a, anyị nwere ike iji obi ike kwuo na a ga-emepụta ihe nrụpụta eserese site na iji teknụzụ 158nm ma tinye uche na transistor ijeri 2 na mpaghara 6,4 mm1408. Ọ nwere 1845 iyi processors na ugboro ruo XNUMX MHz, dabere na-arụ ọrụ mode.
Ngwaahịa ọhụrụ ahụ pụrụ iche na nke mbụ na ngalaba ọnụahịa dị ọnụ ala ọ na-enye ebe nchekwa GDDR6 maka ngwaahịa AMD yana nkwado maka interface PCI Express 4.0. Ekpebiri ịhapụ ụgbọ ala 128-bit, mana ha achụghị oge ebe nchekwa, yabụ na mbufe ozi dị irè nwere ike iru 14 Gbit / s. A maara na kaadị eserese desktọpụ nke usoro Radeon RX 5500 nwere ike ịnwe gigabytes anọ ma ọ bụ asatọ nke ebe nchekwa GDDR6.
Ihe ngosi AMD jiri Radeon RX 5500 tụnyere arụmọrụ ya na Radeon RX 480 na GeForce GTX 1650; A ga-enye ngwaahịa eserese mkpanaka akpọrọ "Radeon RX 5500M" nwere gigabytes anọ nke GDDR6 ebe nchekwa, mana agaghị enye ụdị ntụaka nke ndị mmekọ desktọpụ, n'agbanyeghị na maka ebumnuche ihe atụ, egosipụtara ihe yiri ya na isi mmalite. Ihe ngwọta mkpanaka Radeon RX 5500M ga-enwe naanị 4 GB nke ebe nchekwa, ugboro ugboro GPU agaghị agafe 1645 MHz.
Dị ka ị ga-atụ anya, ihe ngosi ezughị ezu na-egosighi uru nke teknụzụ usoro 7-nm ọhụrụ. Mpaghara kristal Radeon RX 5500 GPU anaghị agafe 158 mm2, ebe ọ nwere ijeri transistor 6,4. N'ịtụle ngwaahịa ọhụrụ ahụ na Radeon RX 480, AMD na-ekwu maka mmụba nke arụmọrụ akọwapụtara site na 70% kwa mpaghara nke kristal.
Nkezi uru nke Radeon RX 5500 karịa GeForce GTX 1650 na egwuregwu nwere ike iru 37% na mkpebi 1080p; Radeon RX 5500M mobile nwere uru karịa onye iro ya na ụdị ekwentị nke GeForce GTX 1650 nwere ike iru 30%. Radeon RX 5500 na Radeon RX 5500M kaadị vidiyo ga-apụta dị ka akụkụ nke kọmpụta na laptọọpụ emechara tupu njedebe nke nkeji iri na ise a, mana ntọhapụ mgbasa ozi na-ekwu ntakịrị banyere nnweta mkpọsa. Nke a na-akọwa enweghị ozi gbasara ọnụahịa maka ngwaahịa ọhụrụ ọtụtụ awa tupu ọkwa ọkwa.
AMD nwere ike inwe ohere igwu egwu na agha ọnụahịa ya na NVIDIA, nke na-ewebata kaadị vidiyo ọhụrụ n'ọnwa a, mana ugbu a ọ dị ka ihe omimi gbara gburugburu ọkwa Radeon RX 5500 bụ n'ihi na ngwaahịa ahụ lekwasịrị anya na ngalaba OEM. . Otú ọ dị, akwụkwọ akụkọ AMD na-ekwu na kaadị vidiyo Radeon RX 5500 nke ndị mmekọ ụlọ ọrụ mere ka a ga-ahapụ tupu njedebe nke nkeji iri na ise, ya mere ọ bụ ihe ezi uche dị na ya ịtụ anya na ha ga-apụta na mkpọsa.
