4770k or 3930k

[boxleitnerb]

I have a 3930K@4.2 GHz and I'm thinking of switching. It will depend on OC of both parts. I would estimate Haswell to have 15% higher IPC. Now if it overclocks significantly better (like 20% or so), then the two extra cores of the 3930K are basically irrelevant since 1.15*1.2=1.4, so 40% which is close to the theoretical 50% you could gain by going from 4 to 6 cores.
You would then have 40% higher performance in games that don't benefit from all threads - which are still plenty.

Btw, Crysis 3 benefits from 6 cores only in certain levels, those with grass. And BF3 is not scaling perfectly with 6 cores either (you only get 25-30% instead of the theoretical 50%). A bit higher clocks and more IPC and you're there with Haswell, too.

 

[Yuriman]

My vote is for the quad with HT. The advantages of Haswell in my eyes outweigh the extra cores. The 3930k will definitely be faster in applications that can utilize all 6 cores fully, but for anything a bit less threaded you'll want Haswell. (plus AVX2, significant performance-per-watt improvements, new chipset with new features)

In a way, it's like the argument for the FX83xx. In select cases it's faster, but it eats a lot more power and is slower in more lightly threaded tasks.

Haswell is also supposed to be better at hyperthreading due to more issue ports. That would further close the gap in multithreading.

 

[Fx1]

Does the installed base drive the development of more parallelism, or vice versa? It's a chicken-or-egg problem.

8 threaded consoles will drive what intel has been trying to do with the PC since the invention of the dual and quad core desktop.

Good if true, as I have said before, I hope in a year's time the 3570K will no longer be the Anandtech forum darling. I'd like to see everyone with an affordable 8 threaded CPU option in their machine, if we build it, will they come?

Well then you've made your mind up. Get a hexa core. I'm not even sure why you made this thread to ask if you've determined already, that the hexa core is better for your needs.

As far as my opinion, if you say so. I'll believe hexa core to provide tangible benefits when it happens. I look at benchmarks of ivy bridge vs SB-E and see IB winning most of them in games, and there are perhaps 1-2 outliers at most. The truth of the matter is, at this time, hexa core really isn't beneficial for games and certainly isn't worth the cost if you value your budget. You can argue the future all you want, but the future isn't here yet - we can only argue what's going on now. And right now, a quad core with hyperthreading and higher IPC is the way to go IMHO. Another fact is that Haswell is very likely to overclock much better than IB-E or SB-E.

That's my opinion. But you've made your mind up apparently, so get a SB-E.

No i honestly cant decide.

But im thinking 4770k is wiser because its cheaper and maybe HT will be enough at 5ghz on a water setup.

Go for haswell

 

[Wreckem]

There should be an LGA2011 IB-E in Q3, so the socket is not quite at its end yet:

http://www.techspot.com/news/52468-intel-ivy-bridge-e-slated-for-september-2013-launch.html

That link also says Haswell-e will be socket 2011 compatible, with the caveat being there will be a new socket 2011 chipest with DDR4 launched around the same time in late 2014 or early 2015.

Link apparently dispels recurring rumors of an alleged 8 core Sandy Bridge E/Ivy Bridge E. Instead the only 8 core will be a socket 2011 Xeon(if the article is correct).

So all y'all dreaming of an affordable 8 core from Intel will keep dreaming until at least 2015, if not longer depending on your definition of affordable. My bet is Haswell-E is the first non Xeon branded 8 core, meaning 8 core won't make its way into the consumer level until Skylake at the earliest?

 

[crashtech]

There seems to be some confusion or ambiguity regarding Haswell and 2011, I don't think it will actually be compatible. It would make much more sense for Intel to alter the land count a bit to avoid this problem, but the fact that they haven't doers seem to lend credence to the idea that there may be some Haswell parts compatible with the "old" 2011, perhaps with some extra circuitry involved ala the old Overdrive setups.

EDIT: I should note this is ALL speculation on my part, take it as such.

You are probably right. There have been a lot of reports/rumors that were completely incorrect. It doubt, Haswell-E supports current 2011 boards. We probably wont know for sure for another year when actual Haswell-E stuff starts trickling out.

 

[Yuriman]

Doesn't Haswell integrate the VRMs? It couldn't possibly work on existing boards unless they drop that for 2011.

 

[tweakboy]

I need it big time.............. 6 core 12 threads Daw , thx gl

 

[blackened23]

I'm 99% certain Haswell-E won't work in 2011 boards. There will even be a new chipset for the IB-E, although it isn't a pre-requisite for most users - a BIOS upgrade may be sufficient for older boards.

Haswell has significant changes which requires a re-design, i'm confident it won't be 2011. Then again, we're talking about a product being released Q4 2014....

 

[crashtech]

Yeah, it's doubtful to me that the new design could be forced to work on the old 2011 even if they had some reason to do so, unless it would be possible to tell the mobo regulators to provide maximum possible voltage to the socket and then let the on-die regulators do the work... surely it'd be a real kludge.

 

[Headfoot]

Get Haswell and take the money you save with the cheaper mobo and processor and invest in more GPU power instead

3570k? Hell, I think I still see more 2500k's in people's sigs than anything else.

 

[cytg111]

Yes on console but PC games will scale up.

64 player on Ps4 becomes 128 player on PC. Planetside 2 already is a CPU hog for example.

They might be 8 slow cores on Ps4 but PC games are going to become better next year. Once games use 8 threads then its easy to scale them up and make them way more complex.

Sounds like you've thought this through, go with SB-E or even SB-EN for 8 cores.. 8 cores should make you feel real good.

 

[bunnyfubbles]

Haswell-E is a long ways off still, what with Ivy-E still not due for a couple of months. At any rate, current s2011 platforms are based on technology that was starting to show its age even when it came out at the end of 2011, and even in the highly unlikely chance that it is somehow compatible with Haswell-E, you likely wouldn't want to keep Haswell-E on such an outdated platform and would want to upgrade to the newest chipset. Basically, investing in s2011 right now doesn't seem very prudent unless you absolutely need the multicore CPU performance.

Im not happy with intel selling OLD Cpu's in extreme guise tbh.

I want a 6 core but i want a haswell one and i want it when it launches in quad core.

 

[guskline]

Haswell seems to be the ticket!

This, exactly this.

 

[jackstar7]

A couple of Veruca Salts in here.

Wait for benchmarks. Why are you trying to make this decision without all the information you need to make this decision?

 

[crashtech]

Because there isn't much else to do right now, all we have is speculation!

I understand that and I wanted the same thing when sandy was released, but Intel doesn't provide that option anymore. You can't buy the best of the best until it is about to be overtaken by the next gen mid range. Sort of takes the fun out of buying enthusiast class hardware if you ask me.
