HD 5850-5870: Final specifications-by ATI
Exactly one hour ago wie revealed the final specs of the HD 5850-5870, . The following are the final ones of the smaller brother, HD 5850, which will herald the new and first AMD DirectX 11 graphic card generation together with the HD 5870.
As you see, the HD 5850 will not have the whole 1600 stream processors and 80 TMUs of the HD 5870. AMD deactivates two of the 20 SIMD units of the HD 5850 to reduce the amount of stream processors to 1440 and the amount of TMUs to 72, which equals a 10 per cent reduction.
Additionally, the chip frequency turns out to be 725 instead of 825 MHz, so that it can only afford 79 per cent of the shader- and texture performance of the HD 5870.
The memory is also bound to a 256 Bit interface and is a type GDDR5, but it works with 1000 instead of 1300 MHz 30 per cent less, so that the memory bandwidth is only 128 GB/s, too, and therefore just above current graphic cards.
The amount of ROPs keeps 32, like the HD 5870.
At the release the HD 5850 shall be 299 USD, exactly 100 USD less than the HD 5870.
The day before yesterday we revealed the specifications of the HD5850. Those also contained 1600 stream processors, 80 TMUs and 32 ROPs, and with that, definitely twice of the HD 4850/4870/4890. This also leaves a mark on the transistor budget of the chips, which is now twice as high with 2.15 Billion circuits. Despite the 40 nm technique the chip size amounts 338 mm², so the chip is the second-biggest AMD chip after the R600.
As we could learn now, the HD 5870 will appear in several versions, one with 1024 and another with 2048 MiB texture memory, although it is still uncertain through the loss of official benchmarks if the bigger memory adds up at all. The doubled memory will result in 50 USD more in price. This means for the HD 5870 with 1024 MiB texture memory still to be at 399 USD, while you just find a < 400 USD on AMD's newest documents, so 449 USD for the 2048 MiB version.

The interesting thing is, that, against our last report, the HD 5870 with 1024 MiB will not work with 825/1300 MHz, but with 850/1200 MHz. If this follows a small last-minute alternation or if the 825/1300 MHz are meant to be from the 2048 MiB version, we will not know until the launch day, which will still be September 23. The performance of the HD 5870 should not experience any major changes.
