Pictures of Cayman and Caicos engineering samples have leaked at
Chiphell. The first leak is of Cayman XT – which some rumours suggest
will be branded as Radeon HD 6870. At first glance, the Cayman XT sample
looks very similar to the reference Radeon HD 5870 with red streaks on
the side. The card features a total of 5 display outputs.
The other pictures leaked relate to Caicos, rumoured to be branded as Radeon HD 6300 series. The sample is a low-profile passive card, ideal for small cases and HTPCs. It is the entry level card in the Radeon HD 6000 series, with 1GB DDR3 over a 64-bit memory. The core is mentioned to be clocked at 650 MHz, with the memory at 800 MHz. With the Fusion era fast approaching, AMD hasn’t yet given up on entry-level discrete graphics cards.
Do note that these are merely engineering samples, and the final retail versions may differ significantly.
UPDATE: Not content with above leaks, nApoleon from Chiphell has leaked more Caicos / HD 6350 pictures – including the die, which is estimated at around 80mm2 by the OP (though others claim it is more like 66.5 mm2). This puts it well above the HD 5450′s 59mm2. 3D Mark Vantage score is revealed to be P17xx, which is also well in excess of typical scores for the HD 5450 – in the P12xx to P13xx range. A GPU-z screenshot is posted as well, though it seems to detect 128-bit memory bus in error. For complete details, browse for pictures in the thread at Chiphell. (You may need to register)
