Despite being 4 days away from the release of AMD’s Radeon HD 6800 series, contradictory rumours continue to circulate around the rumour mill. The Radeon HD 6870 has been believed to be based on Barts XT and featuring 960 SP. However, Fudzilla are reporting that the HD 6870 actually has 1120 SP. The 1120 SP are said to be in the 5D arrangement, unlike the much-rumoured 4D arrangement. Performance is likely to be somewhere between the HD 5850 and HD 5870 but of course, price and power consumption will be much lesser.

Despite being 4 days away from the release of AMD’s Radeon HD 6800
series, contradictory rumours continue to circulate around the rumour
mill. The Radeon HD 6870 has been believed to be based on Barts XT and
featuring 960 SP. However, Fudzilla are reporting that the HD 6870
actually has 1120 SP. The 1120 SP are said to be in the 5D arrangement,
unlike the much-rumoured 4D arrangement. Performance is likely to be
somewhere between the HD 5850 and HD 5870 but of course, price and power
consumption will be much lesser.

If the shaders are indeed arranged similarly to Evergreen, i.e. VLIW-5/5D, there must be some “uncore” optimizations. Indeed, very early rumours stated that the HD 6000 series will feature optimize Evergreen shaders with next-gen uncore units.

Donanimhaber also support Fudzilla’s 1120 SP figure, though earlier they had reported 960 SP. The HD 6850 is now said to feature 960 SP.

For a product releasing in less than 100 hours, precious little is known for certain about the Radeon HD 6800 series, in what must be the most secretive release in quite some time. The release is on schedule for October 22nd and is expected to be a hard launch with availability. All will be clear (finally) then.
