Apple TV 3.2 (2013) a fost lansat in luna ianuarie cu un chip A5 nou despre care v-am vorbit deja in acest articol. Noua componenta inca uimeste multa lume, insa acum o face prin consumul redus de curent si nu prin marimea mult redusa. Daca va uitati la tabelul de mai sus veti vedea ca noul chip A5 consuma cu pana la 50% mai putin curent decat chip-ul A5 din Apple TV 3 2012, semn ca Apple a lucrat serios la imbunatatirea modului in care este administrata energia furnizata catre procesor si componentele interne.
The power savings are nothing short of significant. The previous generation Apple TV wasn’t really a power hog, with platform power maxing out at around 1.6W, but the new model tops out at just a watt. Overall the power savings seem to be around 800mW across the board. With no change to process technology, I can only assume that the reduction in power consumption came from other architectural or silicon optimizations. Assuming you’re using the Apple TV for watching video 8 hours a day, every day of the year, you’d save about $0.26 per year on your power bill (assuming $0.11/kWh). You’d break even on the $99 cost of a new Apple TV in about 385 years. Maybe by then we’ll actually have a true replacement to cable TV.
In cazul tuturor task-urilor chip-ul consuma mult mai putina energie si acest lucru ne da de inteles ca autonomia bateriei iDevice-urilor s-ar putea imbunatati simtitor in baza evolutiei tehnologiilor utilizate de cate Apple. Desi in Apple TV nimeni nu va sesiza vreo diferenta in ceea ce priveste consumul de energie, tot ceea ce a facut Apple acum ar putea trece la iDevice-uri. Ganditi-va la un chip A7 care ar putea consuma cu pana la 50% mai putina energie, ea fiind redirectionata spre alte componente noi sau poate spre o crestere a autonomiei bateriei.
Desigur ca o reducere a consumului unui chip vechi nu inseamna neaparat o reducere a consumului viitoarelor chip-uri, insa avem macar motive reale sa speram ca acest lucru se va intampla.
