Re: wbmw, mmoy - I can't imagine they're going to waste alot of time tuning/redoing single core chips to get them to lower wattage. They're not likely to be used in great volume in very many situations where either performance or power are all that important.

I agree, but for completely different reasons. You should expect Athlon 64 volumes to be quite large, and most likely continue to outnumber dual core volumes for the foreseeable future. The reason why AMD wouldn't be bothered to tune these is probably because they are putting their efforts into tuning the high end of the market, where end-user perception means a lot more. If you can satisfy the top-5% of the market, the halo extends to many segments below that.

Dear J3pflynn:

Going from 65W to 45W on the desktop means a reduction of 30% in power (65W * 70% = 45.5W). So SC Turions will go down to 25W (35W * 70% = 24.5W) and 17W (25W * 70% = 17.5W) which are below Core Solo. In addition, Turion X2 will go to 25W (35W * 70% = 24.5W). This is great for laptops since we all know that power reduction is more prized than performance improvement. In addition static leakage probably went down as well so K8G will be even better at idle. Hours on the same size battery is likely to go up 20-30% (other components won't go down that fast). Lpatops will go from 3-5hrs run time to 4-6.5hrs run time with the same performance.

Barcelona derived mobiles will do even better when each core can have its own voltage. Look for the power reductions to reach 40-50% at same performance. That means that SC Turions will go from 35W and 25W to 17 to 21W and 13 to 15W respectively. DC Turions will drop to 17 to 21W with laptop run times to increase to 4.5-7.5hrs. Add high performance ATI chipsets and integrated GPUs and Intel will be in a world of hurt.

And that is before AMD's increase in capacity is figured in.
