the information you have given regards with Intel® Core™ i5-3210M (TDP 95W)
is wrong the max TDP of Intel® Core™ i5-3210M is 35 watt
that is lesser than Intel® Core™ i7-3610QM (TDP 45W).
this link tell the truth :-ARK | Compare Intel® Products
now the question about TDP,
higher the TDP => low battery backup
but clock frequency is high that means processor works faster.
