It was billed as shootout for third place in the pool - but in that respect, it was machine guns v water pistols.
Exeter did nothing spectacular. They were simply too efficient and powerful for a Cardiff side that made a string of changes and clearly lacked cohesion as a result.
Both sides will now be in the last-16. The Chiefs however, will have a home tie while the Welsh side will be on the road.
Exeter do get a fifth try and it's the best one of the 80 minutes.
Harvey Skinner sears through a gap and then produces a clever grubber kick to the corner. Paul Brown-Bampoe, who has been superb today, gets the score he deserves with a brilliant pick-up by the corner flag.
Cardiff are still playing here, but like night follows day, an aimless chip comes after several phases of getting nowhere.
Moments later and a great offload from Dan Thomas gets them back on the front foot only for Ioan Lloyd to throw an attempted miss-pass straight into touch.
Exeter have definitely dropped their levels of intensity in attack as Cardiff press again.
But their simply struggling to make inroads. Another attack breaks down and Stephen Varney looks to break away - but luckily for the away side he's called back for an Exeter knock on.
A loose ball bounces up for Cardiff hooker Evan Lloyd and he bulldozes over halfway.
Deja vu though. After running out of options, Johan Mulder opts to kick and it's an aimless one.
The amount of times Cardiff have run out of ideas today has been telling. That Bowen chip aside, they have rarely threatened to breach the Exeter defence.
