Recentemente, a AMD lançou sua nova linha de processadores desktop, chamada \"Vishera\" (arquitetura piledriver). Que é sucessor natural da antiga \"Zambezi\" (arquitetura bulldozer).
Nomes dificeis e esquisitos a parte, ficou entendido que os antigos bulldozers foram um grande fail, principalmente no quesito RENDER. Agora, a AMD fez um pequeno refinamento da antiga arquitetura (nada muito revolucionário) criando e lançando a novissima piledriver com o intuito de se manter competitiva no mercado. Alguns reviews destes novos processadores ja estão circulando na web, e levando em consideração o que mais nos interessa aqui nesta seção do forum, podemos dizer que a amd deu um bom passo a frente.
Seguem alguns números:
______ processador | preço_ | render | consumo
AMD___ FX-8350 ___ | US$195 | 2:36s_ | 182,21W
Intel_ i7-3770 ___ | US$305 | 2:30s_ | 129,90W
Intel_ i7-3930K __ | US$595 | 1:52s_ | 164,00W
Com isso ja pode-se tirar algumas conclusões. O processador AMD conseguiu empatar tecnicamente em performance de render com um intel i7 mediano (3770), e o melhor, custando 2/3 do preço. Mas por outro lado, notem o consumo absurdo de energia dele, 40% a mais que o do intel. Isso tem que ser levado em conta e pode desanimar muita gente a fazer uma renderfarm com processadores AMD. Já para um workstation de custo baixo (ou de bom custo beneficio) ele poderá ser uma ótima pedida.
As reviews ainda estão muito recentes, e as informações limitadas. Teremos de esperar a utilização em massa (e quem sabe de algum usuário aqui do forum) para tirarmos conclusões mais sólidas.
Abaixo, link de alguns reviews. Que peguei do forum overclock.net
