Next generation intel CPU on the way ?

venur · Jun 26, 2013

Hi I already own an i5-3570k so I'm fine but my second computer is an old core 2 quad and is badly overdated for the game that my GF play nowadays.

When I'll buy a new CPU I'll just give her this i5-3570k. At first I wanted to wait for the new intel generations but the old PC keep crashing and after a lot of investigation I suspect the CPU.

We have any news about the future generation or I shouldn't old my breath and just spend a lot of $ on an i7-3770k ?

Sadly I was hoping for a better upgrade :-(

The haswell (4th gen) has been out for a couple of weeks already.

Its only really an upgrade though, if you dont overclock. The old 3570k outperforms haswell once overclocked as it takes voltage increases far better.

The next generation was released recently. The new equivalent of the Core i5-3570K is the Core i5-4670K. The new CPUs require new motherboards with the new LGA 1150 socket. The performance improvement is quite small.

Sakkura :

oh I wasn't aware. Dam since I already own a pretty good mobo I,m not sure if I wan't to spend about 600$ just for a tiny increase.

I might just get a cheap mobo for my GF give her my old 3570k and buy a 3770k.

And by the new 1150 soket I guess that mean my 1155 wont work ?

What si the new i7-3770k equivalent ? I might just buy that one and get a mid range mobo (I don,t feel to pay 280$ for a mobo this year).

In all fairness, for mere gaming purposes its not really worth it to buy a 3770k either. Save your money for a year or two and see what games start demanding. Then you should be able to kit out a significant PC

Or if you must spend it, sink it into a high end GPU upgrade.

And yes, 1155 and 1150 are incompatible >.<

It's the i7- 4770k.

Still not really worth it, to date, most games dont take advantage of hyperthreading. Sit on that wallet of yours

Sadly the PC of my GF will probably just be dead before the next year and I don,t feel like spending 250$ to get her a new CPU and have no upgrade for me

ATM pretty much only crisis see a real advantage of hypertrading but I expect it will change during this year or maybe the other one so I might go for an i7 already I don't know yet.

Haswell is 5-7% faster then Ivy and can easily be overclocked. It just isnt as easy as sandy and ivy bridge overclocking

Intel God :

The trouble is it generates far more heat when you increase voltage.... For the same temperatures you can push an ivy further enough that it eats up that 5-7% faster.

Intel God · Jun 26, 2013

drtoast :

Not really. Haswell is pretty much just ivy bridge with some tweaks to the backend.

You would serve yourself better sticking with that CPU, buy her a new 3570k if you must. or 3570 if you dont overclock and pinch the dollars...

Then you still have enough to treat yourself at a later point when you know its worth it, rather than speculating and having it turn out a waste.

And you would see greater performance from a new GPU than a CPU will ever give you.

You do notice that the last reading is for a different speed right? thats where the difference settles in...

http://www.xbitlabs.com/articles/cpu/display/core-i7-4770k_12.html

clock for clock it runs ten to twenty degrees hotter

drtoast :

I already run 680gtx sli buying another one would be a 400$ upgrade and we all knwo that 3way sli money/performance start to decrease a lot. Buying an i7 over an i5 is only about 100$ and only provide a minor upgrade for playing crisis at this moment.

So actualy going for an i7 now comes down to would I spend an extra 100$ for a chance to skip another CPU generation or do I save 100$ now I guess.

Look at that xbit Graph. The voltages werent the same. The 3770K was using 1.088v and the 4770K 1.116v. Ofcourse haswell is going to run hotter using more voltage :lol:

drtoast · Jun 26, 2013

Intel God :

But thats the whole point. In order to match and make stable Haswell needed higher voltages, that it cant handle as well. Thereby allowing the ivy to catch up and outclass again.

To paraphrase the summary of that article, Haswell is a low power high efficiency chip. Thats where it holds its own, put it out of its narrow set of restrictions and it rapidly looses favour.

Even the Tom's article summarized it as being great for mobile purposes, but a near definite item to skip for desktop users.

True enough, but consider that by the time things have advanced for a i7 to become worth its cost, there will be newer chips, in newer sockets (potentially not even 1150) and the i7 would be outdated by what will then be current tech.

But I too would skip an extra GPU with sli 680's

I didn't know what you were running

You cant compare a 3770K at 4.6Ghz and 1.40v against a 4770K at 4.6Ghz and 1.35v. It doesnt work that way. Every chip is different. I dont think i've ever seen two chips need exactly the same voltage for a set speed. Furthermore who cares about the temps at 3.7Ghz. I want a 4.6 vs 4.6Ghz temp comparison.

True The old i5-2550k can easely be overclocked at 4.7 while the i5-3570k will probably end at 4.5 with the same cooling solution due to running hotter then the sandy bridge. But the ivy bridge still able to perform 5-10% faster on any real benchmark application.

drtoast · Jun 26, 2013

It's still the case that you can push an ivy that much further than a haswell, using the same cooler. Enough that it outclasses it.

Just using abitrary numbers as you have,
i5-3570k @ 4.5ghz @ 1.0v 60 degrees
i5-4670k @4.5ghz @ 1.1v 70degrees

well lets say you give the 3570k 1.1v and an extra ten degrees, it will run at say 4.7ghz.

You have more headroom for OC'ing on the ivy, it isn't limited by containing a hugely reactive heatsource inside the chip itself.

You also call for a 4.6 to 4.6 comparison, yet the graph you provided wasnt even that. Don't expect me to present you with something to contradict you and say its not valid if I cant, when you didn't provide that either.
