Did you actually do the calculations? I'm using the most recent stat weights I know of as of 2.4:

Augmented Ironworks chest: 47 crit x .215 = 10.105 INT + 33 spellspeed x 0.098 = 3.234 INT + 5 extra INT from being i130 vs i120 = 18.339 INT.

Demon Robe: 31 crit x .215 = 6.665 INT + 31 det x .284 = 8.804 INT equals a total of 15.469 INT...REALLLLY close to the Augmented Chest, but not "better" by any means, and that's not including the extra VIT you get from upgrading.

However, as i120 vs i120, there's no contest - get the Demon Robe.
