    Better than expected

    Better than expected
    Clearly marked as a 2.8 GHZ processor. However, in the description of the item it stated it as a 4.0 GHZ. They have since changed the headline to say "up to 4.0 GHZ". After about 1 week of gaming, I would have to say I see a noticeable upgrade from my previous CPU (i5-7400 3 GHZ). Also, I use this PC for video editing and this new PC made a HUGE difference. Happy with my purchase. Only gave 4 stars due to the misleading title when first purchased.

    5.0 out of 5 stars La mejor CPU de Intel tanto por calidad-precio como para juegos por menos de 200 €
    Reviewed in Spain on September 4, 2018
    Desde marzo se me antojó cambiarme de componentes en mi ordenador. Tenía anteriormente:

    -CPU: Intel Core i5 4440 3.1GHz
    -GPU: Asus Strix RX 470 OC 4GB
    -Placa: Gigabyte B85M-D3H
    -RAM: 16GB DDR3 1866MHz
    -Fuente: Aerocool KCAS Bronze 600W

    Lo único que quería cambiar fue la CPU, la placa y la RAM. Ya que como mi anterior PC tenía Intel de 4ª generación, CPU de DDR3, y placa con socket de 1150. Para saltar a la nueva generación, tenía que cambiar la CPU, que además, había que cambiar la placa, y había que cambiar la RAM. Opté por el Intel Core i5 8400 de 2.8GHz, la RAM era Ballistix Sport LT de 16GB DDR4 de 2400MHz (8x2) y la placa era Gigabyte B360M-DS3H.

    Con todo esto, manteniendo la gráfica y la fuente de alimentación, obtuve unos mejores resultados tanto en embalaje de productos, como de calidad de estos mismos. Del i5 4440 al i5 8400 ha sido como un 30% o más de mejora, así como la mejora de la RAM al pasar de 1866MHz y DDR3 a los 2400MHz y DDR4.

    La CPU si bien a mí se me calentaba unas pocas veces debido a las múltiples tareas que hice los primeros días (instalar programas, juegos, etc), el rendimiento es indiscutible que es de calidad-precio. Por menos de 200 € tienes una buena CPU. Con respecto a los juegos, probando The Witcher III: Wild Hunt en Alto-Ultra mantuve alrededor de los 60 y los 75fps (activé la V-Sync porque el tearing del juego me molestaba, y mi monitor era de máximo 75Hz), y los resultados eran sobresalientes, sino que más destacables. Si queréis montaros un buen PC para jugar, el i5 8400 es una buena inversión para lo que vale, podéis jugar a prácticamente todo con este procesador. Se aprovechan muy bien los 6 núcleos y 6 hilos que tiene, con frecuencia de base de 2.8GHz y turbo de hasta 4.0GHz.
