I've read the part that you quoted and once again it only consolidates what I was saying. I don't mean to be rude but I have no idea what the hell you're trying to tell me.

I want to change mine E8400, but now I doubt, Ivy Bridge is better for OC than Sandy or it is better on Stock?
Which is better for OC to 4.5Ghz: Core i5 2500K (Sandy) Core i5 3570K (Ivy) And which is better on Stock (no OC): Core i5 2500K (Sandy) Core i5 3570K (Ivy)

I have to say the antagonism in these forums is overwhelming at times. I was decent enough to explain what I meant and yet you still try to undermine what I've said by telling me your Mum's P4 is still running after 10 years. Firstly you've told me nothing about the pc's usage....was your Mum running Prime95 for 12 hours a day, or perhaps intensive sessions of Maya 3D every day.....or perhaps she was just using it sporadically to check emails and web browse? What about dust levels or the average cpu operating temps? (I'm sure you haven't been monitoring these for 10 years). Also like I said if the temps were on average 10degrees below Tc, you should expect the cpu to last at least 6 years. I never said a cpu couldn't last 10 or 12 years, in fact quite the opposite. If a cpu is run at lower temps it is more likely to last longer. There will always be outliers in statistics, data that doesn't follow the general trend, and can largely be ignored in the broad scheme of things. Your Turion laptop still works but my Sony Vaio SB with i5 2410m cpu which was constantly being run at temps around 80 C failed after just 6 months. I would still expect almost all of the other Vaio SBs to make it through the 2 year warranty period. One data point means nothing. A warranty period can tell you a lot about a product's life expectancy. High end PSUs come with at least a 5 year warranty because they know that under normal usage most of them will make it through( probably 95% or so). You have to remember that Intel will design for the worst case scenario (in this case someone constantly using the cpu at thermals close to Tcase), and draw the line at how many cpu's they are willing to have fail the warranty period. It does not make economic sense for any company to over engineer a product, but there will always be a safety margin. The 'statistics' you ask for do not exist. Statistical analysis is an integral part of any product design and is largely based on lab tests and theoretical studies. Intel do not wait around for 10 years to find out how many Pentium 4s have failed before they decide on a warranty period for a product that they launched 10 years previously. Besides I feel that this is starting to veer off topic.

@hyperspeed
The 3570K isn't THAT much faster than a 2500K anyway. If you have the money for it, by all means, go for the 3570K. In both scenarios, the 3570K will be a bit faster, but it will probably have a slightly higher temperature than the Sandy Bridge. 04-26-2012, 12:38 AM

$200 more than a 2500K? That's a lot. But I guess that's how the prizes are in Brazil.
It's only €30,- more expensive here. The 2500K will be a great upgrade for that E8400. All you have to do is add a decent cooler to it, and overclock it. |
