On the Chinese side for the first time we .pcinlife.com are GPU-Z screenshots of AMD's DirectX 11 entry-level second-generation emerged. The new models Radeon HD 6570 and 6670 the family "Turks" are, according to AMD's road map to be available later this quarter. The most noticeable changes compared to the previous card HD 5570 and 5670, the sumptuous memory configuration: AMD doubles the memory to 2,048 MB of GDDR3 for the HD 6570 and 1024 MB of GDDR5 in the HD 6670 on two graphics cards, which is connected remains at 128 bits. Especially the weaker and less likely to benefit from 6570, when it may be imagined - the good cards are gladly offered in OEM PCs, which has a particularly large amount of graphics memory proven sales tool.
The computing power is sufficient here in practice, not to exploit the large memory makes sense. The remaining data are more Evo than revolution, is lifted, for example, the chip clock of the Radeon HD 6670 HD 5670 compared to the 25 MHz to 800 MHz, the HD 6570 is clocked at 650 MHz just as its predecessor. The number of the stream processors on both cards rose only slightly from 400 to 480th Duplicates were also ROP units, it now amounts to 16 instead of eight. Accordingly, the hardware also affects the performance, the video cards are in the 3DMark 06 score slightly above the values of their predecessors
