Jarred's view is like mine:
And in one of the comments:
If you actually read what you linked, they expect as much as a 75% performance increase over previous generation. I didn't expect as much, but I do expect more than the ~25% increase you were saying (15% on top of the 10% dif between 285M and RM 5870), something like 40% average.
They do not mention 100w being imposible or going to fry anything. 100w is high, but nowhere near anything to worry about when the laptop is plugged to the grid. 285 SLI is much harder to cool and power and many laptop designs exist with this config. Mobility Radeon 4870 X2 laptops exist too and they too consume much more than 480M...
BTW I forgot to mention this in the last post, but how much % of laptops come with 180w AC adapters according to you? You know they exist right?
The difference between the 285M and 5870 is not 10%, it's more like 20%. (btw you can't just add up percentages like normal numbers)
Jared says 15% faster than a 5870, just like i said.
I never said it's not possible to have a laptop with such a high power usage. I said it's crazy.
I really don't see the point of a 8kg laptop. Why do they even call it a laptop. Anybody crazy enough to put one of these on their lap is going to be sterile afterwards.
Some people mentioned LAN parties but i think a game system built in a micro-ATX case is much more efficient.
And you reference to multi GPU configs to be as power hungry. True, but it's easier to implement efficient cooling of two separate 50W GPU's instead of one 100W GPU in a laptop.
If you check out something like an Alienware laptop with multi-GPU, you'll see that they put the two MXM modules far from eachother. Each being cooled by a separate cooler and heatsink. It's becomes a bigger problem when all this heat is coming from one spot (in a laptop i mean).
As you see in Anand's post, there won't be an Optimus enabled GTX480M laptop.
So what advantage does it hold over a 5870X2 setup? Because that's what i keep refering to and that's what you keep dismissing. Same money, same heat, no battery life but faster.
If you want the fastest, no matter the weight, then that would be the 5870X2.
