OK I've played a bit with the rx480, here some first impressions:
Here's some 1:1 comparsion 290x and 480 on the same system with the same driver: https://docs.google.com/spreadsheets/d/1...=133823274

- Card's almost as fast as a R9 290x for some very lightweight algorithms
- For more compute intesive algorithms it drops to around 10% - 50% of the performance of a 290x. Looks like the algorithms using fast shared memory somehow do not make efficient use of it
- Some algorithms run faster, which I think is not true. It's more likely that the 290x code generated with the new driver is somehow bad
- Card is not getting as hot as the 290x, even under load
