i5 4670K haswell at stock or moderate overclock, or prev. gen i5 30-something K on a higher OC

[H2OMC]

I'm going for a CPU upgrade, and so far I've had my eye almost exclusively on the i5 4670K. That was until I heard about how hot haswell tends to run. So my question is: save some money and get a solid overclock out of a 3xxxK previous-gen i5 or get a moderate overclock out of the 4670K haswell and still see performance gains vs. the previous gen i5. I'll be running with an Asus ROG mobo so overclocking won't be a problem on that end, and my cooler will be a hyper 212 evo. I'm interested to see what TH has to say about this conundrum. Cheers!

I always prefer newer tech. There always ends up being some perk or capability that I wish I had purchased.

You could always di lid the cpu a lot of folks are doing that due to the piss poor thermal paste intel used in the heat shield on the die.

A 4670k @ 4.2ghz will perform equally to a 3570k @ 4.5ghz and will consume less power AND probably run cooler.
However, a 4670k @ 4.5ghz would run a lot hotter than a 3570k @ 4.5ghz.

I'm not at that level yet I'm afraid. At some point I may well start getting into light modding but for the moment I'm not ready to go there. Thanks anyway

I'm with you there. I'm just looking to save some money if I can get the same or better OC performance out of a lower level cpu than the 4670K.

Getting 4.5ghz out of a 3570K with the 212 evo cooler isn't too much of a stretch is it? Seems pretty easy to obtain but I have relatively little experience overclocking. You're saying I should go for the 3570K on the higher oc and save some money. If that's the case, I'm all for saving money.

I detect some bull here, one being that the obsolete Ivy Bridge generation would be cheaper than Haswell when in reality Intel never lowers their prices of old CPU generations. Any price reduction you can possibly find would therefore be coming from a dealer that wants to get rid of his Ivys. Not too likely.

The other bull is that Haswell would run hotter than Ivy Bridge. A much repeated and quoted rumor, but a false rumor nonetheless. On the same conventional code, Haswell delivers ~10% more performance and does not run any hotter than Ivy Bridge! The only case in which Haswell does run hotter is when you run new AVX-enabled code, reason being that then Haswell activates its AVX unit while Ivy Bridge has no AVX unit in the first place and needs to emulate the AVX code. As the consequence, Haswell then delivers a whopping 70% higher performance, totally outclassing Ivy Bridge and still delivering a lot more performance per Watt of heat than Ivy Bridge.

There really is no reason to buy the old stuff. People suggesting that just have not understood the above.

Haswell may be somewhat harder to overclock than Ivy Bridge, but as discussed before a Haswell on stock clock speed already delivers the performance of an overclocked Ivy, so there is nothing Haswell would have to catch up on.

When not under full load Haswell draws even less power than Ivy Bridge, because he has a set of enhanced power-saving states that Ivy also does not have.

Go for the 4670. You can go for the overclocking K variant, but remember the additional performance is not for free. You pay more for the CPU, and unless you go for a non-Z-overclocking-BIOS, you need the more expensive Z87 chipset that otherwise confers no advantage you are likely ever to feel. So you do pay dearly for those additional MHz and should wonder whether they are actually worth the price. You also lose the CPU's virtualization capabilities and most power saving features when you go for overclocking.

I see your point, and what you say answers some questions I had, but I don't see the need for insinuating that the rest of the people on this thread are stupid. Even so, what you said makes sense, so thanks. Virtualization is something I'd like to be able to take advantage of so it's nice to know that overclocking will get in my way on that front.

I recently bought the i5-4670k and a z87 MOBO, and I have to say it is better than the Ivy Bridge counter. I have seen that it runs at roughly the same temps as the other, but I do get better stock performance. When it comes to overclocking, the i5-3570k is easier to get a stable clock because the manufacturing on the 4670k is a bit shoddy, but nonetheless it is still viable and more rewarding. When I overclock the 4670k, the temps rise faster than the 3570k at a point, but before that, point the performance is much better. When overclocking both to around 4.5 GHz, the 4670k is a bit hotter in my case, but its performance is outstanding. Both are great CPU's, but you should go with the newer one because that will also future proof your build a bit more. When the next gen comes out, if it uses the same socket type, you won't have

No I was actually saying it's better to have the Haswell at 4.2ghz than the Ivy Bridge at 4.5ghz. Performance is equal, but the Haswell consumes less power and will likely not be as hot.

This is basically the same thing I said above. The only thing here I disagree with is this-

When it comes to overclocking, the i5-3570k is easier to get a stable clock because the manufacturing on the 4670k is a bit shoddy,

The opposite is true in this case. Haswell doesn't overclock as well because they are set up to be more efficient. Manufacturing is actually tighter, not allowing much overclocking headroom. Intel has worked to improve power consumption and efficiency with each generation. Expect more of the same from Broadwell.

And something that DeathAndPain and I are never going to agree on is, that just because Haswell is out and is better than Ivy Bridge, doesn't automatically render Ivy Bridge "obsolete" unusable trash. Ivy Bridge is still very good and there is nothing wrong with building an Ivy Bridge system right now IF you can save money on it. Ivy Bridge stuff is often cheaper than Haswell.

I just oppose false statements. Whether you regard affirming false statements as equal to being stupid is up to you. As far as I am concerned, I do believe that people should be cautious with affirming stuff unless they are sure they know what they are talking about, or otherwise at least indicate that they are just guessing. These false rumors would never have become that widespread if all people applied that caution.

I agree with what you're saying. First post just came off a little strident. I've gotten some good info out of this thread and that's what I was looking for. Cheers!
