[OBR] 3770K (E1) vs 2600K (D2) Graph

post #1 of 25
Thread Starter 
I haven't seen this graph around here yet. It shows some interesting results for volts, temps, power consumption and Cinebench performance. It's a good side by side visual for 3770K Vs 2600K. One can clearly see the curves are steeper for everything except performance.

Those large increases in heat and power consumption make the marginal increase in performance over SB inconsequential.

Ivy Bridge = Intel's Bulldozer. Waiting for Haswell lolz.

All my opinion though.

The question is, how reliable is this data?

It seems to fit everyone else's reports on the issue. It seems to hit a point (in these figures around 4.8Ghz) where the power consumption and heat generation go through the roof.

wow sb is better imho do you guys think it comes down to the TIM instead of solder on the IHS?

You dont need 1,5 volt for 4.9 lol. Some members here achieve 4,8 with 1,2 volt

All of these reviews that compare them at stock can be very deceptive. If these results are what we can expect to see, then the power consumption is really not a win for Ivy, It's clear that over 4.2 ghz this chip becomes more power hungry. Also, the voltage is only better at < 4.7 ghz, which is less than ideal for a chip on a smaller process. And the temps, well we all knew about that... Form many of the reviews, we have also seen the performance when overclocked, does not scale as well as Sandy. The Cinebench score here ranges from 2.2% to 1.6% when overclocked.

I hope this is not a new trend from Intel. They seemed to have focused more on the IGP than anything else, and from the info floating around the interwebs... They will be "revolutionizing" the Haswell IGP. I really hope they don't forget to make Haswell a powerful CPU, because that's just what it is! Many people that buy the i5-i7 chips aren't even using IGP. Sure I guess it can be attractive for OEM systems for the non-savvy family, and powerful HTPCs, but that's it.

Hmm, interesting. I guess for that 1.34v the 3770K is around 4.6Ghz. So no problems on overheating, just if you want to pass 4.5Ghz, then you need a monster cooler, or a monster airflow case, or some watercooling. And if you are lucky, you can achieve even less than 1.3+v for a 4.5Ghz overclock. smile.gif

That's what I was thinking.

The review seems a little harsh on the Ivy side of things.
