Specifications for the much-anticipated ATI Radeon HD 5830 have leaked, courtesy of Chinese site IT168.com, and there's a little disappointment in store for anyone expecting a bargain HD5850 alternative.  The slide - which is tipped to have come from an internal presentation deck - confirms the rumored $250 pricing window, but also that the new card is down a significant 320 stream processors, 16 texture units and 16 ROPs on the HD 5850.

While it was expected that AMD would shave performance off the HD 5850, early estimates hadn't assumed the difference between the two models would be quite this extensive.  The end result is a card capable of 12.8 GPixels/s, 51.2 GSamples/s and 1.79 TFLOPs, versus the HD 5850's 23.2 GPixels/s pixel fillrate, 92.8 GSamples/s Z/Stencil and 2.09 TFLOPs of compute performance.

Bizarrely maximum power consumption is up, however, at 175W compared to the HD 5850's 151W.  It's not entirely clear what's going on there, but we'll be watching the early reviews very closely to see if the ATI Radeon HD 5830 is actually the mid-tier enthusiasts card we all hoped it would be.
