2. They seem to be saving power by removing a bunch of pipeline hardware, which was supposed to be what gave the current chips so much speed.. how they're doing that and keeping up the speed without bumping the clocks, I still don't really get.
Go look at the Pentium M architecture (which is what most of the new Pentiums are based on).
3. Still no onboard memory controller... hah. Still gives AMD an edge.
Some, but not as much as you would imagine. If you are concerned about power, you will try to avoid keeping the memory saturated anyhow.
4. They're removing HyperThreading, which makes me want to laugh again since that was yet another "best thing since sliced bread." technology. Removing that for more power savings.
Hyperthreading is generally useless overhead when a processor is not fully utilized (which is the case when you care about power).
5. Each dual core pair is sharing L2 cache. Ouch..
Not really a hit if you can make that single L2 a factor of 2 bigger. If power is your concern, you are going to turn individual cores on and off. Again, you will be lowering your memory bus usage and waiting an extra couple of cycles for results to come back is a useful thing.
Don't get me wrong, the AMD stuff is still better, but this stuff is not that big a deal.
