AMD To Launch Radeon HD4890 "RV790" In April

Um,there cores are not fast enough so they sing some other sad song.Geforce used 512bit and performance was great.Dont give us excuses give us POWER. Plus they are a lot of games that love bandwidth,So how is it wasted.

The pros simply have to outweigh the cons.
They could have made the RV770 'virtually' (As CJ described) bigger/larger so pin-counts and bonding pads wouldn't be a problem, it also would have result in a much cooler chip. The same chip, but just made bigger. The pros of a small economical die was probably more rewarding than a big 512bit chip.
