Latitude 5491 med en sexkärnig i7-8550H CPU och Nvidia GeForce MX130-grafik presterar bättre än Latitude 5490-modellerna med ULV CPU:er och integrerad grafik - ibland med stor marginal. Det förstås, för att kunna dra nytta av dom två extra CPU-kärnorna behöver program vara designade för att använda de extra trådarna. Utöver en rejäl ökning i prestanda så bockar Latitude 5491 av alla korrekta rutor då den fortfarande är samma väldesignade och säkra företagslaptop med utmärkta inmatningsenheter och god ergonomi.
Med det sagt så finns det fortfarande rum för förbättring: nya Latitude blir väldigt varm vid belastning och på grund av det är den sämre på att upprätthålla turbo boost. Fläktarna behöver jobba hårdare så systemet låter mer än tidigare. Dell har också valt att använda samma blanka tryckkänsliga FHD-skärm som Latitude 5490 är utrustad med. Panelen lämnar mycket att önska, då ljusstyrkan är alldeles för låg för att den ska kunna användas utomhus och både färgomfång och färgnoggrannhet misslyckas med att imponera. Dessutom kommer den här modellen med en större och mycket tyngre nätadapter och den håller inte lika länge på en laddning.
Vägkrigare som i huvudsak fokuserar på ordbehandling, kalkylblad och webbsurfande kommer troligen klara sig bättre med Latitude 5490, som har längre batteritid och inte blir i närheten lika varm och högljudd. Den som är nöjd med prestandan en ULV CPU kan erbjuda borde även överväga Lenovos utmärkta ThinkPad T480 eller T480s.
