A feature providing increased computer performance by overclocking without complicated settings in the BIOS.    

It is the function providing multi-threaded parallel processing instructions - from one physical processor are created two virtual processors. In practice this means that it significantly reduces the system response and at the same time accelerates the operations, which you require from the processor.

Ešte nikdy nebola rýchlosť WiFi taká dôležitá. Schválne si skúste spočítať, koľko máte doma bezdrôtovo pripojených zariadení. Určite ich nebude málo. A keď k tomu pridáte napríklad požiadavku na pohodlné streamovanie videa, on-line výučbu alebo home office, tak drvivej väčšine routerov dôjde dych. Preto je potrebné WiFi sieť nielen zrýchliť tak, aby zodpovedala štandardu WiFi 802.11ac. Čo všetko takýto štandard dokáže a čím sa líši od starších WiFi generácií?
