Considering this, Juniper should have been marketed as HD5800.If Barts XT is 10% slower than the 5870, but $150 cheaper, silent at full load and is 25% less power hungry, you can't tell me that's a bad deal overall. On pure performance sure but everywhere else it's a good deal.
On top of these improvements, it offered full DX11 capability over HD4870 and power draw was down by ~50%.
Is it so hard to find a good example that you show the perfect opposite?
And I think I already said "economics" wasn't in favor of such a move... The goal is not to pile many references in a $10 range with the most expensive one $30 more expensive than the cheapest one at the production level, leading to a situation where you force the client to reduce your margin.
To counter that, the opposite move is preferable: $100-150 75-watt "6", $200-250 150-watt "7", $300-400 225-watt "8" and a $600 300-watt "9" using twice the "7" part has nothing shocking. This leaves "5" and "4" as entry/value and 3 digits for the integrated stuff.
Of course... nothing is known yet (not even are we certain the naming scheme will persist), it's stupid to state Barts can't be called "8" on its own merit and already tag it as a fail, but if it's indeed "8" and the mainstream part, it's going the wrong way, however you look at it.
