ALL of the other leaks have shown the 4770K runs extremely hot. Haswell is essentially Ivy Bridge but with more GPU power and VRMs adding to the heat.

What is going on?

Probably wasn't 100% stable

ALL of the other leaks have shown the 4770K runs extremely hot. Haswell is essentially Ivy Bridge but with more GPU power and VRMs adding to the heat.

Meanwhile at Intel HQ
Intel manager: Ivy bridge didn't run hot enough to persuade overclockers to buy Intel X79, so let's add more heat on the die and not use solder... that will show those overclockers why they need to buy Intel EXTREME processors to overclock more than 4 multis tongue.gif
Intel Engineer: Why do we need a better iGPU on an unlocked CPU? Why not put the better integrated graphics on the lower TDP i3 CPUs like AMD APUs?
Intel manager: People would buy more i7s to get better graphics!


More seriously though, the VRM is probably adding more heat as well as the vastly improved iGPU. I didn't see a GPU in that review on their HWMonitor

so now my question has finally been answered, the most anticipated question, the heat problem, and yes we have it folks, we still have that dang heat issue.

Aren't the main benefits of Haswell chiefly for laptops and smaller devices ? I thought I heard battery life will be increased to large margins i.e. ten hour increase. This alone would fund this chip to the Stratosphere!

More seriously though, the VRM is probably adding more heat as well as the vastly improved iGPU. I didn't see a GPU in that review on their HWMonitor

A part of me genuinely thinks that may be the reason they switched from solder: Intel didn't want their Performance chips to overclock too high and perform uncomfortably close to their Extreme segment. I don't buy any of the cost-related theories; Intel has some pretty healthy profit margins on their hardware.

It's the same reason you won't see the full-blown iGPU or overclocking on the dual-cores. That would eat into sales of the more expensive CPUs, even though it would be the logical thing to do.

Why would you think that temp. is bad??
