3770K just slightly faster than 3770T? What?

major malfunction detected
In any case the Core i7-3770K turbos to 3.9Ghz, while the Core i7-3770T turbos to 3.7Ghz.
This 200Mhz difference is a ~5% difference in clock speed, and the benchmark number is ~10% different in our benchmark charts. Which seems reasonable. Hard to see why anyone would purchase the 'T' variant however, unless it was way cheaper.

Hmm, I can post paragraphs this time it seems. Weird.

The base clock speed on these new CPUs doesn't mean much.
When idle they drop below this base speed. When under load they ramp up above the base. So in fact they aren't often operating at the base speed.
Turbo is not only used for single threaded apps.
Its max TDP is 45W, who wouldnt want it?

I would think you could buy a Core i7-3770K and slightly under clock it to get a similar effect at full load

Yes, a cold room might make your CPU faster for longer, depending on the circumstances.
There is a summary of Turbo mode functioning on Wikipedia.

I don't think power usage in Watts and clock speeds have a linear relationship, but I don't have the hard figures to prove this.

No need for overclocking anymore, eh?
Note also that TDP refers to how much cooling is required. Not how much power is actually used by the chip.
So a 45W TDP chip (with cooling sufficient to dissipate 45W) might actually exceed 45W of power usage. But after a while it will get too hot and throttle down a bit due to overheating.
