AMD Ontario APU pictured,die size ~77mm^2

Reading comprehension problems ?

N550 - 8.5W, 1.50 GHz, dual core, GPU
N475 - 6.5W, 1.83 GHz, single core, GPU
N450 - 5.5W, 1.66 GHz, single core, GPU


Let me repeat : you're stuck in 2008. We are in 2010. Today's Atom that your find all over the place ( cast a look emag ) integrates on the same die, the CPU+GPU+NB. Clear ?

So total power for the T40N would be 9+6w=15w ( SB ) while for the N550 it would be 8.5+2=10.5w

30% less power at platform level which with the same battery and screen would translate into 30% more endurance. Using the other N models only increases this advantage.

Current Atom : everything on a single die.





You do understand that what you're saying equally applies to Atom chips also ?

Think this is the link that you were quoting it from. Most of them are single core atoms and well, as far as i'm concerned, priced slightly higher as there was no competition as yet.

Then again TDP is indicative of a thermal design envelope where the rating in W is the maximum temp that the given chip could operate in. AMD quotes TDP as the maximum as allowed by the engineering design. Intel quotes a recommended design point, which is not indicative of a potential maximum draw by that chip.

see the linked articles for reference...

Also, if you look at their i series chippery, let us take the most popular, i7 920, the Acore is 100(max) and Vcore is 1.37(max)... the formula to calculate TDP is rather simple, multiply both... it comes to 137W, whereas Intel quotes only 130W :P

Also, there's a lovely quote about how Intel measures TDP in the arstechnica article. Now AMD, when it says Bobcat's TDP is 9W, you know maximum drawn will be 9W, which is the worst case scenario and almost never happens. Atoms however, expect them to be running at that maximum allowed in that envelope. Then again, that is not the maximum that an atom chip could draw... I couldn't find Vcore and Acore info on Intel site as well, what could they be hiding?
