Yea seems better and somewhat cheaper.
The cpu from the Anandtech overclocking/undervolting
review showed that anything above 4.8 was a struggle heat/voltage wise.
It seems ivy doesn't respond as well to voltage as sandy did. The diagrams at the bottom where a voltage increase from 1.1 to 1.3 only netted 0.3ghz doesnt bode well, it does seem that the correct voltage for the processor will lead to an ok increase in mhz, just looks like finding that voltage might be a bit more tricky...
As for reasons why it might not OC as well, Overclocking has always been about getting the most out of the processor within reason. Gains is always the first to be put into perspective and putting the 3770 next to the 2600k it looks like this:
2600k: Standard 3.4ghz Turbo 3.8ghz 8mb cache and HT
3770K: Standard 3.5ghz Turbo 3.9ghz 8mb cache and HT
Now the 2600k is known to overclock to 4.8 around ~1.4volts from stock voltage around ~1.2. So for a 1Ghz increase over the Turbo speed only required 0.2v difference.
Anand's 3770K got to 4.8 around 1.3 volts from stock voltage of around ~1.1. This makes it a 900mhz increase over Turbo speed but requiring 0.2v to do so.
To add to the fact its at a 100mhz loss is the Heat factor. @ 4.8 the 3770 was reaching 95+ degrees, where as the 2600k was not.
I dare say it will turn out that Ivy will have a 'sweet spot' for voltage that will offer the greater returns for Mhz increase over heat/voltage.
Meanwhile its a hard decision to make a call on the 3770k, if your not overclocking the 3770K will do fine, but whats the point of getting a k series processor if the previous generation, the 2600k can overclock to the point that the new technologies in the 3770k cant make up for the difference?
onto the next review
