Then why the hell didn't they call it R380? If its a new GCN chip, redesigned with all the efficiency focus and all.
Cramming it between R280 & R290 is just stupid.
Product names do not usually bother me. But 285 sounds just plain... stupid.
Also 2GB; if this was nvidia it would be cheap and stupid, but NV being NV perhaps they can get away with 2GB.
AMD, offering low additional value and making sure 7950/70, 280/x owners do not upgrade - this is mega stoopid.
There must be something more to this that we don't know.
Like really small chip, temporary stopgap solution with R9 280/x perf. to fight off GTX 760/70, and with faster 4GB models around the corner.
Anyway, AMD already did something similar with 5850/70 -> 6850/70
