The Xbox One X is heavier (8.4lbs) than the Xbox One S (about 7lbs) because of its new internals. In terms of dimensions, it's larger than its predecessor in terms of length and width, but it's encased in a slightly thinner chassis. Its top sports a smooth black matte surface, unlike the Xbox One S, which has tiny holes at the top for ventilation. However, the same multi-hole design is still featured on its sides.
