Actually, he only has about half of that, even post-training.
He lacks all of the "absolute" features- he only carries Superhuman class characteristics- which is super weak in overall strength scaling. His striking strength is not infinite- his strength post-training is at Moon class. He is f r a g i l e in scaling (Wall class durability)
Saitama also has a tendency to not take combat seriously. His only major characteristic listed here is FTL movement speed, which does in fact far outdo Doom Guy (but not his weapons)

HOLY SHIT
as of Doom 2016, if equipped with the Sentinel Hammer, Blood Punch and his power-ups, he's a f**king Class 2-A
He can destroy multiverses when equipped with those.
Attack potency is listed at Multiversal
Massively Hypersonic+ reaction time, meaning he can't move like Saitama but can react fast enough to avoid him
Class G lift strength (very big)
Striking Strength is F**KING STRONGER THAN SAITAMA at Multiversal+
