Intel 3570k or 4670k?

I know these chips are similar in performance, but i'm seeing a lot of threads complaining about poor OC'ing and heat issues along with delidding a brand new cpu LOL.

I'm building a new system, I have a PSU/case already and wouldn't want to replace it.

It's a corsair 620w.

I'm looking to upgrade from E6600, replacing mobo, cpu, ram and gfx card.
 
What's the point of new cpu's these days if they hardly improve?

Im thinking about upgrading to one of these but im not sure as my old pc still plays everything ok and it's really not that great, seems waiting was a bit pointless as things have hardly improved in the last few years, i don't want to upgrade if im paying just as much now for something i could have had years ago.

Also gpu's seem even worse, only the high end really improves, you'd expect the mid to be at least as good as the high end of the previous gen but all we seem to get are slight improvements or rebranding of mid and low end gpu's, it all makes me wonder if real progress has ended.

Better idle temps and clocks and voltage, the difference for me was huge coming from a 2500k at 4.6ghz.
same oc as my current one without any issue and still the new z87 just works great with windows 8, was the smoothest installation I done ever.

so sometimes it isnt for the better ipc but also the new features which for me was a good reason to go haswell and the performance boost is noticeable for me even though the features ranks higher. I enjoy desktop as fast as possible.

That's nice if that's all you care about but i always thought the point of new hardware was a fair increase in performance and features, all we seem to get with cpu's now is maybe a 5% to 10% increase in single core performance, we don't even get much if any increase to ghz now either and i know that it isn't everything but we could have a hundred core cpu and it wouldn't make much difference if software can't or won't take advantage of it, just look at this to see how bad things have gotten and there's no sign it's going to get better, we could be waiting five to ten years before we see a real doubling of performance, surely that's a bit pathetic?

It's not the best data to represent your point about how bad it might be getting. And it is only one perf metric (single thread) under one condition (Specint). As shown in the graph its a prediction (no actual data points beyond 2010) from on an AMD presentation on exascale computation.http://www.lanl.gov/orgs/hpc/salishan/salishan2011/3moore.pdf. Speculatively with a combination of a some data points and industry knowledge they show specint single thread perf reduction coinciding with dropping the MHz approach Specint is a timed benchmark, so naturally there is a slow down as any gains would then come solely from IPC instead of more clocks in a timeframe. That industry has long since drifted away from single thread to absoulutely massive parrallelisation to increase computing throughput.

Dropping the mhz race, as indicated in the graph, relates to physical limitations such as power draw and also practical thermals. Having said all that yes we are getting smaller relative single threaded advancements year on year as single thread performance cannot be progressed with synergistic process and architecture advances as we were used to. And importnatnly even transistor budget for increasing core IPC is in a sense stiffled in preference for multicore and integratated features - to me a valid alternate form of progression beyond just the single thread perf metric. It's just not usefull for all cases.
A better graph looking at single thread improvement would have been one further down from the same link you posted http://preshing.com/20120208/a-look-back-at-single-threaded-cpu-performance. But even that is out of date and would show a further slowing trend to date. Although that data is relative, so in absolute terms it probably doesnt look quite as bad year on year, but that is no consolation when looking at how much faster something can be processed now than before, or will be in the future with greater unparrellisable processing demand.

Anyway im not really going anywhere with this just that the graph is a little sensationalist presented on its own out of context. And that the reasons behind why it displays what it does are actually quite interesting.
 
At the end of the day all that really matters is whether we're getting a worthwhile performance increase for a given price point each year or so, considering in the past we had doubling of performance, if we can't even get half that now i really think things have gotten pathetic and progress is going to take a very long time, they could bundle hundreds of cores and it wouldn't help much for most applications, although if they did i would be happy to see real-time raytracing games, that's pretty much the only way they'll make this rubbish ok.

Go for the 4670k, its socket will be more future proof. The price difference is little now but it will pay for it self in the future.

Most people change their CPU and motherboard at the same time so 'socket proof' doesn't really mean much.
 
I have a 2500K. To be honest, when you take into account the fact that Ivybridge overclocks better than Haswell, and then Sandybridge overclocks better than Ivybridge, I doubt very much you would see a difference between a max OC'd 2500K and a max OC'd 4670K let alone a 3570K and 4670K.

I don't plan on upgrading until Skylake, possibly not even then if I pick up a 2600K for cheap along the way. The slight performance gains per 'half gen' don't make upgrades seem worthwhile at all at the moment.

I would even question going from an overclocked 920 to a 4770K ro be perfectly honest. Sure there will be a significant performance gain there, but is it really worth the loss of money? The 920 is still a very capable CPU.

Just my thoughts. :)

You could pick up a 2500K for ~£100 on the MM with a bit of haggling if you are lucky, and a nice Z68 board for ~£60.
 
Go for the Haswell CPU the 1155 socket is at the end of the line but 1150 is just starting. The price difference is probably worth it for the 10% gain in efficiency clock for clock.
