A Lenovo aprimora o seu ThinkPad L440 versão 20AT004QGE com uma tela HD+ e SSD. No entanto, isso não o torna um portátil de gama alta acessível para profissionais. O contraste de 200:1 é abominável e as mudanças de cor DeltaE ainda são muito altas. Os contendores com telas HD+, o Latitude 3440 e ProBook 640 G1, tem mais para oferecer aqui (melhor contraste). O ProBook com um SSD custa apenas 50 Euros (~$62) a mais, e embora o Latitude 3440 tenha menos recursos profissionais (dispositivos de entrada, interfaces, construção), custa apenas 670 Euros (~$840) com uma placa de vídeo GT 740M.
Apesar de tudo, nosso sistema de teste lidera a comparação no desempenho de aplicativos porque compete contra sistemas HDD (Latitude 3440, ProBook 640 G1) que inclusive tem um SoC mais fraco de baixa voltagem em alguns casos (Latitude 3440). O Turbo da CPU é maximizado, e o afogamento não é um problema. Qualquer um em bisca do melhor desempenho possível, além dos jogos, encontrará o ThinkPad L440 com SSD simplesmente perfeito.
