Bydd Cyflymu Cymru yn golygu y bydd y rhan fwyaf o gartrefi a busnesau'n gallu cael mynediad at gyflymder lawrlwytho band eang sydd dros 30Mbps erbyn 2016, gydag o leiaf 40% o bob safle yn yr ardal ymyrraeth hefyd yn cael mynediad at wasanaethau dros 1000Mbps. Mae hyn yn cyd-fynd ag uchelgeisiau'r Undeb Ewropeaidd i gael band eang cyflym iawn dros ardal helaeth erbyn 2020. I gefnogi'r uchelgais hon, mae'r UE yn cyfrannu £90 miliwn drwy raglen Cronfa Datblygu Rhanbarthol Ewrop (ERDF) i gynorthwyo i ddarparu a chyflwyno Cyflymu Cymru ledled Cymru.
Superfast Cymru will mean that the majority of homes and businesses will be able to access broadband download speeds in excess of 30Mbps by 2016, with at least 40% of all the premises in the intervention area also benefitting from access to services in excess of 100Mbps. This is in line with the EU’s ambitions for widespread superfast broadband by 2020. To support this ambition, the EU is contributing £90 million via the ERDF programme to assist funding the delivery and roll-out of Superfast Cymru across Wales.
