Currently AMD invites selected representatives of the press in order to present their newest generation of graphic cards, the HD 5850 and HD 5870 series, which will be released at the end of the month.
According to SemiAccurate the new graphic cards offer over 1600 stream processors. Trusted sources confirmed this feature and enabled us to have a closer look on the architecture of the cards.
Actually AMD quite simply doubled the number of SIMD units from 10 to 20. Still every SIMD unit contains 16 5D units and a Quad-TMU. Overall: 1600 stream processors and 80 TMUs.

Based on equal clock frequencies the new models have theoretically twice as much shader and texture performance as the present HD 4850 and HD 4870 series. Though increasing the power more than a 100 per cent will just be possible in a few cases, as the memory interface is still restricted up to 256 bits. Nevertheless AMD improved the performance quite a lot and developed a remarkable graphic card series, which outclasses his older brothers easily.
