[citation][nom]Tomfreak[/nom]6670 is roughly the 25% of 7970 speed, IGP being half of that should be somewhere 12%, the inefficient crossfire scaling down to 5-10% gain is still worth something if it is done right, it may be worth more for 7800/7700 setups. But these definitely worth something for people to still run 5800/6800 series. The crossfire support for the hybrid GPUs are poorly taken advantages compared to the traditional Twin GPUs. Almost every modern games are well supported on traditional crossfire. They could have at least make a similar discrete GPU to get better support on games, rather than crossfire across different architecture, 6670 is a HD5000 chip, it has poor tessellation performance, make note of that too. the problem here is the hybrid crossfire dont work half of the time. it is not like they wont gain something else by introducing discrete VLIW4 GPU as they are generally more efficient, and all these power saving on VLIW4 are a big thing in mobile world, since most of the time GPU in mobile are a lot more inferior than their CPU. A reliable crossfire with APU + GPU that work almost every game is a significant advantage over Intel's CPU + GPU combo. Trinity APU + VLIW4 GPU in crossfire is MUCH better gaming platform than Intel sandy bridge with VLIW4 GPU alone. They got the asset, but the implementation is poorly executed.[/citation]
Excellent points, I admit that, but again, any video cards such as Radeon 7800 and 7900 would probably be rather CPU-bottle-necked. Trinity is probably able to more or less keep up with Phenom II in gaming performance (maybe not the top Phenom II models, but at least with some of the upper models) and that simply isn't enough in some games. I also say that I would like to see AMD widen the CF support of their IGPs and low-end VLIW4 cards would make excellent replacements for Radeon 6600, 6500, and 6400. Just keep in mind that although Trinity's IGPs are pretty great, they are limited in CPU performance and would be more detrimental to gaming performance in at least some games using the IGP in conjunction with the high end discrete card than disabling the IGP for some serious overclocking.
