That's still likely but what I'm pointing out isn't about the cost of those chips but how meat heat they generate.   While the CELL was expensive, it didn't run all that hot comapred to a high end GPU.   Look at the difference in the GPU between the PS3 and  the rumors for PS4.

PS3 GPU - 70 watts.
HD 7970 - 250 watts
HD 7950 - 200 watts (entire PS3 at launch was 200 watts)

The ability to dissipate heat hasn't advanced much so there just isn't any way possible for them to include a GPU that runs that hot.

Makes sense. However, the point of the rumor isn't that it will be a standalone GPU but part of an APU that is intended for high-end laptops.

However, it will likely have a lower-end 7xxx GPU than the 79xx. Probably almost entirely due to heat.

See, you couldn't even make the HD 7970/7950 as part of an APU.  Chips are too big and hot for that.  Those APU's won't use a GPU base with anything higher than a 60-70 watt GPU.  Otherwise, you'd need a CPU cooler the size of you computer monitor just to keep it cool.
