Intel Core i5-4278U

Intel 4278U

De Intel Core i7-4278U is een LV (low-voltage) dual-core processor voor ultrabooks, gelanceerd in het derde kwartaal van 2014. Dankzij Hyperthreading kunnen de twee cores tot en met vier threads in parallel aan, wat leidt tot een efficiënter gebruik van de CPU. Elke core biedt een basiskloksnelheid van 2.6 GHz maar kan dynamisch overklokt worden met Turbo Boost tot en met 3.1 GHz.

Architectuur

Haswell is de opvolger van de Ivy Bridge-architectuur met verbeteringen op het vlak van zowel GPU- als CPU-performance. De CPU's zijn geproduceerd in 22nm en bieden een geoptimaliseerde aftakkingsvoorspelling en bijkomende execution ports, wat de prestaties in verhouding tot de kloksnelheid met bijna 10 procent verhoogt. Bovendien zouden nieuwe features als AVX2 en FMA de prestaties voor toekomstige applicaties moeten verbeteren.

Prestaties

Dankzij deze architecturale verbeteringen zijn de prestaties iets hoger dan die van een vergelijkbaar geklokte Ivy Bridge-CPU. Daarom is de Core i5-4278U bijna even snel als de oudere i7-3520M. Indien de nieuwe instructiesets zoals AVX2 gebruikt worden, kan de performance aanzienlijk hoger liggen. Daarom heeft de CPU genoeg rekenkracht voor office- en multimedia-taken, maar ook voor meer veeleisende applicaties.

Graphics

De geïntegreerde Iris Graphics 5100 GPU biedt 40 Execution Units (EU's) geklokt aan 200 - 1100 MHz (met Turbo Boost) wat de chip aanzienlijk sneller maakt dan de HD 4000. Bijgevolg concurreert de Iris Graphics met trage dedicated mid-range grafische kaarten (bv. GeForce GT 720M). Zelfs snel dual-channel-geheugen zal de performance echter beperken.

Energieverbruik

De i5-4278U is afgestemd op een TDP van 28 Watt, inclusief grafische kaart, geheugencontroller, VRM's en de geïntegreerde chipset. Daarom is de CPU geschikt voor grotere ultrabooks met een goede koeling.
