Overclocking Core i7-3770K: Learning To Live With Compromise

[blazorthon]

[citation][nom]ErikO[/nom]Indeed, I just purchased a 3920XM, and I've got HD4000 graphics, which I'll never use - even in my desktop replacement / laptop.I've done 4.4GHz at stock voltage, and wonder how it would have gone without the necessary graphics on the die.I mean really, who buying an Extreme processor wants / needs integrated graphics?[/citation]

A lot of people using high end CPUs would rather use integrated graphics. Perhaps most would. Many high-end users aren't doing graphically intensive work and would rather have integrated graphics that uses next to no power rather than a discrete card.

52 watt for a full system !!! How the hell ?

My 3770k + 7970 + 450w activepfc psu + ddr3 1600 consumes 125-140 watt idle, dependig on if my 2 7200rpm disks are on or off...

The 7970 should consume less than 6870 if i remember correctly :-(

The 6870 consumes much less power than the 7970 does at load. At idle, maybe the 7970 could drop a few watts below the 6870.

I remember the 6870 rated at 20-27 watt idle, and have just found an article on Anantech stating that 7970 is rated at 15 watt idle.

Asus probe states that the cpu consumes 5-7 watt idle..

i wonder how TH managed to get the system down to a mere 52 watts - when i can't even get it below 100 watts ...

I am so confused now would like to build a new system to replace my aging Pentium D - was thinking one of the 2600k or 3770k since they cost around the same.

I was consider the 3930k also, but it's a lot more expensive it seems. What would you experts recommend? Always used Intel chips btw.

3770K of cause... Newest Tech, and if you OC you get same perf almost as 3930K ... plus 3770K is cheaper then 3930K

What do you intend to do with this system?

If you overclock the i7-3770K, then you're just as likely to overclock the 3930K if you buy it, so the overclock argument that you make isn't very accurate.

Internet, watching 1080p vids, ripping DVDs etc (i.e. most tasks apart from gaming).

LOL... Then get a Core i5 3550K instead... 3770K is only for people who Encode Video or do HEAVYYYYYY Work on their PC.

 

[cos67]

Ripping & encoding DVDs sorry lol. Compressing vids into rars etc - nothing too extravagant

Then you'll never notice the difference:

Hmmm comparable performances it seems.... Ok thanks man.

Good review. I am very content with my 2600k. However, if you are not going for crazy overclocks Ivy Bridge is a good upgrade (if you don't already have Sandy).

i overclocked the processor just fine to 4.4 (the supposed sweet spot) with stock fans while not applying any sort of thermal paste.... never reached past 66C the entire time on a stress test.

that does not seem any worse than what the old processors could do, besides, getting an old generation chip is just silly, unless you found it for a nice sale or something

 

[Jalockin]

is the 5.0ghz possible to hit with the 3770K with better cooling than the stocked CPU cooler ?

 

[blazorthon]

Chances are against reaching 5GHz even with high-end cooling for that CPU. A little below that is much more likely.

 

[Jalockin]

So the better choice would actually be the 2600K or 2700K i can't really see what should speak in 3770K's favor then when 2600K will reach 4.8ghz on stock cooling and out-perform the 3770K in most of the benchmarks.... I think my mind is made up now 2600K or 2700K it will be with mid/high-end cooling. Don't know if the H80i is categorized as high-end (love the H100i, but I would have to change chassis to fit it).

They're all on-par except maybe with the 2700K having a slight advantage. None of it is enough of an advantage to matter. 4.8GHz on Sandy versus like 4.5GHz on Ivy is equal performance due to Ivy's greater performance per Hz. Best case scenario is that you go for a 2700K and reach like 5GHz to 5.2GHz and maybe you'll then inch out Ivy at about 4.5GHz to 4/6GHz, but not by enough to say that Ivy is really out-performed. They'd still be incredibly close. Having even a 5% advantage is not going to make a difference and that's assuming that you could get that much. Heck, even a 10% difference won't make much of a difference except maybe in very large time scales.

H80i is high-end AFAIK, but it's probably not ideal for the price.
