If Barts is 270mm˛ it has to have at least 1280 shaders. Juniper is what, 150? With 800... If AMD has gone 4-way on this architecture as most seem to believe and that this move would increase their shader density even further it would be practically impossible for a chip to be that size without a quite big increase in shaders (compared to Juniper) or just a slight decrease compared to Cypress.

If Barts XT has 1280 shaders we could expect it to perform in line with 5850 or better. This because of increased shader efficiency, higher clocks and higher memory bandwidth.

Dave Baumann has several times in the Beyond3d-thread stated that the 5800-series is the anomaly regarding price. This leads me to believe Barts is truly 6800-series, will be cheaper than current x8xx cards, will probably be a good purchase. I don't think AMD wants to get hundreds of reviews saying they've got worse performance/$ than their last generation.
