3570k @4.7Ghz vs 3770k @4.5Ghz What would you use?

[Edited] Mistake - the 3770k is @ 4.4Ghz not 4.5Ghz.

Hello peoples,

I want to ask a question for my best mate as he is to lazy to sign up and post this himself.

So this is the situation. He had a PC with an i5 3570k overclocked @4.7Ghz with a custom loop that was just for gaming and the usual web surfing e.t.c., but now he's started using it for transcoding/recoding HD movies for family and friends, at LOT of movies.
So recently he went out and bought a i7 3770k thinking that it would overclock just as good and with the hyperthreading it would increase his PC performance when transcoding and reduce the times for transcoding.
Unfortunately the 3770k seems to be a pretty bad overclocker, I've tried for him but it won't go any more, it can only reach 4.4Ghz with a voltage of over 1.40v. Whereas his 3570k overclocks to 4.7Ghz at only 1.3v. Temps are under 80c on both chips after a few hours on Prime.

So this might be a derp question, but what would in your opinions be the better (More Powerful) chip for transcoding/recoding??? A 3570k @4.7Ghz or a 3770k @4.4Ghz+HT?? Is the HT on the i7 worth more than the 300Mhz extra on the i5??

I know a lot of you are gonna say, "Well test it! Which ever takes the shortest time to recode a movie is the best chip". But he doesn't like swapping the chips about. I've offered to do it for him but nah, he's stubborn!

Would appreciate any opinions, advice, input.... anything at all.
Thanks very much.

Probably the 3770K, with its larger cache, it should handle movie encoding slightly better than the i5.

When you tried it, was it under the custom loop?

The 3770k is obviously the better chip but it does sound like a lot of voltage is needed for a decent OC.

Not much I can say besides what you don't want to hear. Test it in a real world scenario and see if it makes a difference.

Attention! My bad, I typed incorrectly. The 3570k is @4.7Ghz but the 3770k is @4.4Ghz not 4.5. Sorry.

Thanks guys. So you would say the extra cache and HT is worth more than the 300Mhz drop on the clock??? I was always under the impression it was only equivalent to around 100-150Mhz over a none HT chip at the same clock.

Yes, both were tested in the same rig and with the same loop. I know what you mean, when he called me to say he needed help OC'ing it as the voltage was near 1.4v I thought something must be wrong, but after weeks of trying, I think he just got a bad chip =(
