Core i7-3770 and Core 2 Quad Q9550, which CPU produces more heat (No OC) ?

The Q9550 would run hotter. Improvement in energy efficiency and thermal specs were part of what made original Core i5/i7 processors like the 750 and 920 better than earlier generation CPUs. While Ivy Bridge processors have worse heat dissipation than sandy Bridge due to the smaller 22nm process, that's only a factory when overclocking, not at stock speeds. And both still are better in that department than older Core 2 Quad.

The i7 950 will out run the c2q 9550. Why? seem on the specs, no hyper threading interior the c2q. subsequently it has 12MB of cache. Have some computers. platforms geared up with i7 920, i7 960, c2q 9505. The c2q is rapid to start yet runs out of steam because of the fact the burden will strengthen, distinctive abode windows and courses working. The i7's strengthen velocity interior the comparable difficulty. Gaming is a various difficulty. Hyper threading isn't use finished. The c2q is a older platform of processor, to no longer say it does not carry out, the i7 could do exactly it greater useful. Now with the Sandy Bridge processors the i5 is the winner in gaming. this is superb if all you do is pastime with it. all around utilization of the pc? The i7 nevertheless shines! desire it helps.

I like Core i7-3770 which cause less heat.
