Other information has also come to light offering up a further Orbis advantage: the Sony hardware has a surprisingly large 32 ROPs (Render Output units) up against 16 on Durango. ROPs translate pixel and texel values into the final image sent to the display: on a very rough level, the more ROPs you have, the higher the resolution you can address (hardware anti-aliasing capability is also tied into the ROPs). 16 ROPs is sufficient to maintain 1080p, 32 comes across as overkill, but it could be useful for addressing stereoscopic 1080p for instance, or even 4K. However, our sources suggest that Orbis is designed principally for displays with a maximum 1080p resolution.

The raw teraflop measurements being mooted - 1.23TF for Durango and 1.84TF for Orbis - have been dismissed as meaningless, and to a certain extent that is true. However, check out AMD's specs page for all of its various GCN hardware and you'll find similar metrics based a very easy formula derived from clock speed and CU count. It's not the be-all-and-end-all of processing power of course, but these are accurate measurements used by AMD itself in giving a broad assessment of the raw computational power of the parts it creates. You'll find that the next-gen console parts slot in quite nicely with their PC equivalents - in short, the teraflop metrics aren't much use in isolation but they are effective for comparison purposes in terms of base hardware capabilities.

On paper, Orbis looks like the tighter, more powerful, more games-focused design. With Durango, the astonishing lengths to which Microsoft has gone to accommodate 8GB of RAM adds further weight to the hypothesis that its plans for the Xbox hardware extend beyond gaming, that it wants the hardware to form a next-gen media centre. The question is to what extent its non-gaming plans impact on the processing resources available to developers...
Zumal das nicht die erste Quelle ist, die meint, dass man kaum große Unterschiede feststellen wird.
