Overview na processor Intel Core i5-750: bayani dalla-dalla, kwatancin da kuma sake dubawa

2009 ga saki da updated processor gine Lynnfield, mafi wakilin wanda ya samuwa a lokacin da guntu "Kor i5-750». A halaye na wannan semiconductor samfurin ba haka ba ne sosai daban-daban daga yau yan hudu-core CPU daga wannan manufacturer. Saboda haka, wannan CPU har yanzu ci gaba da zama dacewa da kuma iya warware mafi yawan matsaloli na dukan a lokacin.

Alkuki processor kasuwar, wanda aka mayar da hankali hali na wannan mujalla

Tare da LGA1156 «Intel" microprocessor kasuwar dandali kasu kashi da wadannan segments:

• Shigarwa-matakin PC dangane Celeron sarrafawa (wadannan kwakwalwan kwamfuta samar da wani m matakin na yi ishe ofishin kwakwalwa) da kuma Pentium (a wannan yanayin, iya ko ƙidaya a kan jefa wasu sabon toys a magangara mafi ƙasƙanci saituna, amma wasan haka da tsarin naúrar za a iya kira wani stretch ).
