Um utilizador do f\u00f3rum Chiphell partilhou duas capturas de ecr\u00e3 do GPU-Z que revelam, alegadamente, as especifica\u00e7\u00f5es da placa gr\u00e1fica Radeon RX 6600 XT e RX 6600. O GPU-Z adicionou recentemente suporte para ambas as placas gr\u00e1ficas RDNA 2, ainda n\u00e3o anunciadas, para que as informa\u00e7\u00f5es sobre a suas especifica\u00e7\u00f5es sejam precisas.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Estas placas gr\u00e1ficas ser\u00e3o as primeiras unidades RDNA 2 a tirar partido do Navi 23 da AMD. As imagens mostram ambas as placas gr\u00e1ficas a correr em interfaces PCIe 4.0 x8, o que \u00e9 bastante intrigante. A AMD limitou as placas gr\u00e1ficas Radeon RX 5500 XT e RX 5500 anteriores a uma interface PCIe 4.0 x8. Portanto, ser\u00e1 interessante ver se a hist\u00f3ria se repete com a Radeon RX 6600 XT e a RX 6600.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A Radeon RX 6600 XT, que \u00e9 a mais r\u00e1pido dos dois RDNA 2 de\u00a0 m\u00e9dia gama, pode chegar com 32 unidades de computa\u00e7\u00e3o (CUs), que equivalem a 2.048 processadores de fluxo (SPs). Se o n\u00famero for preciso, a placa gr\u00e1fica apresentar\u00e1 tamb\u00e9m 32 Ray Accelerators para ray tracing. \u00c9 prov\u00e1vel que a Radeon RX 6600 XT chegue com 32 MB de Infinity Cache.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

No que diz respeito a velocidades de rel\u00f3gio, a Radeon RX 6600 XT surge com um clock base de 1.692 MHz e clock de boost de 2.684 MHz. O ID do fornecedor do subsistema aponta para a AMD, portanto, esta Radeon RX 6600 XT em particular pode ser um design de refer\u00eancia, ou r uma amostra de desenvolvimento, portanto, as especifica\u00e7\u00f5es finais podem variar.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A Radeon RX 6600, por outro lado, pode ser limitada a apenas 28 CUs ou 1.792 SPs, que s\u00e3o acompanhados por 28 Ray Accelerators. Esperamos que a vers\u00e3o n\u00e3o-XT tenha um cache Infinity de 32 MB semelhante.

Aparentemente, as gr\u00e1ficas partilham um aspeto em comum: o sistema de mem\u00f3ria. Ambas parecem exibir 8GB de mem\u00f3ria GDDR6 com clock de 16 Gbps. Dada a interface de mem\u00f3ria de 128 bits, a Radeon RX 6600 XT e a Radeon RX 6600 oferecem apenas at\u00e9 256 GBps de largura de banda de mem\u00f3ria.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

As ofertas de RDNA 2 v\u00eam com mais mem\u00f3ria e mais r\u00e1pida em compara\u00e7\u00e3o com outras. No entanto, a largura de banda da mem\u00f3ria \u00e9 menor devido \u00e0 interface de mem\u00f3ria estreita. No entanto, a Infinity Cache est\u00e1 presente para mitigar a baixa largura de banda.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Em rela\u00e7\u00e3o ao desempenho, este utilizador afirma que a Radeon RX 6600 XT e a Radeon RX 6600 obtiveram uma pontua\u00e7\u00e3o de 9.439 e 7.085 no benchmark Time Spy, respetivamente. Aparentemente, temos uma diferen\u00e7a de desempenho de 33,2% entre as variantes XT e n\u00e3o XT. No entanto, o Time Spy \u00e9 um benchmark sint\u00e9tico, aplica testes default que diferem de uma utiliza\u00e7\u00e3o real, portanto, essa diferen\u00e7a de desempenho pode sofrer altera\u00e7\u00f5es.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
