i7-4770K was benchamrked in few test at Tomshardware. What I seen, is it about 5-10% better than i7-3770K, no more (without CL HD4xxx optimalization). SO, what do you think? :)

Nice, looks like a decent improvement all around, specially graphics wise. I'm excited and can't wait for oc results and more info.
I mean, for users dont have logic change SB or IB for this...(only for enthusiast). But yes, HD graphic has very nice improvements in performance.
nice scores nice improvement. as you said it doesn't make me upgrade over 3770k but but if i build a system today sure i will wait for this.
For someone building a new PC,if price is right, 4770K is the best you can buy. But for someone who already own SB or IB I doubt this would be a good upgrade. You have to sell your board and CPU ,buy a new combo, and for what? 3-8% IPC improvement with similar OC margin? Seems like a waste of money to me(unless someone doesn't care much for money and wants absolute best). Until AVX2/FMA3 workloads become normal IB at the same clock would be pretty much indistinguishable in legacy workloads from Haswell.
the return performance is less with every generation it seems.Quote:

the see3 performance improvement being so small makes me think the only gains in IPC from this processor are coming from code path optimization additions to ss4+.
makes me wonder if all IPC improvements are imaginary now adays and directly related to the new code paths , SSE4 avx.
Not much IPC improvement...
New software will just add an extra code path, old software just gets a minor boost. But it's not imagery if you utilize it. If I remember correctly Sandybridge shuts off part of its SSE engine for SSE3, it's been 2 years since AVX was introduced both companies support it and both console makers have built their next gen machines with it. In new software, SSE3 will be like x87 support within two generations of CPU if x86 and PC's in general survive the 'ARM's race'.Quote:

making it appear like this generation is improving on die performance. while its really more optimizing the available then actual rawr performance gains from more compute units.
would these improvements shown , go beyond the software used, or be equal for improvements for all the alternatives.
cause if it only improves the performance with 1% of the software you use. but if you switched all your software, then you could get upto 10%?
ok , due to Bad Thermal Grease in Ivy Bridge , Is Haswell hot as IV ? did Intel fix it ? Hope Intel gives us good new
the culprit behind the overheating issues of Ivy is not the thermal grease but the black adhesiveQuote:

the black adhesive glue is too thick making the gap between the die and IHS wider than it should be.Quote:
Compare all the "a" cases to the "b" cases, the only functional differences in these two test conditions is the CPU TIM. Notice that the Intel stock CPU TIM outperforms the NT-H1 replacement TIM once the CPU-to-IHS gap is identical
(all the "b" cases are ~2-3?C warmer than the "a" cases)
And if we remove the paper shim and drop that IHS down onto the CPU (not perfectly zero of course, there is still some NT-H1 CPU TIM there after all) reducing the gap to as close to zero as possible then we get the "c" cases...and the temperatures show the expected fantastic drops we have all come to expect from delidding our Ivy Bridge chips.
Conclusion: The Intel stock CPU TIM is not the reason Ivy Bridge's run hot, and replacing the Intel stock CPU TIM is not the reason a delidded Ivy Bridge runs so much cooler - the benefits of delidding are entirely due to the resultant reduction in gap height between the CPU silicon die and the underside of the IHS.

Seems like I will grow old with my 2600K. Does Intel really not want people with a Sandy or Ivy Bridge desktop chip to upgrade? Give us at least a 6 core as a minimum already!!! And I don't need silicon spend on an igpu.
GPU with eDRAM on laptop will be a beast. Everything else is as expected..
this. Its been over 6 years since Q6600 was introduced. Its 2013 and still no mainstream 6 cores.. AMD's HSA seems more interesting than this :/Quote:

That's an ugly abuse of math, AVX code is up to 100% faster than SSE3 so if you switch you get that boost +10%. And in some cases a simple recompile will get you a significant chunk of that gain. As for lazy coders, optimizations can lead to incorrect output, computers do these equations by brute force, optimized code tends to work by simplifying what you can get away with. But sometimes when your code is solid you have to draw a circle and treat it like a square to speed things up (note exaggeration). Not every good optimization can be figured out in time to ship a product.Quote:

What I found interesting in THG preview is Sisoft Sandra FMA results. Haswell does perform better than IB/SB but not nearly good enough when you look at the "theoretical" boost FMA could bring- they gained only around 18% of FP performance Vs 256bit AVX codepath. They mention that the FMA results are latency bound so this could be potential bottleneck . This could mean that Haswell-E/EP won't be making huge performance jumps(~2x) in spec fp tests when compared to IB Xeon derivatives. Maybe this is why AMD has not opted to expand their FlexFP unit to native 2x256bit FMA pipes, they expected that intel won't be getting such a massive lead with Haswell's implementation of FMA.
Thanks for the heads up on this article Flank3r , now waiting to see performance and overclockability under cold :) , that will decide if I jump in the bandwagon of Haswell or I keep my good 3770K cpu and Z77 platform.
it seems like my decision to wait out IB and go for Haswell was a good idea
My Q6600, while amazing, is showing its age now.
I think people asking for large leaps in performance are beginning to expect to much. if you think about how much money Intel is putting into the development, it shows that silicon is simply reaching the point where it cannot progress much further.
they've pushed it as far as they can and now it's more down to instruction set optimizations and software optimization to become more efficient (i'm looking at you, Microsoft)
Going from Q6600(OCed) to IB or Haswell is almost like going from Prescott to Conroe ;). Massive leap in overall performance ,massive leap in min. fps in games, massive leap in encoding/rendering. It's money well spent.Quote:

with the lazy programmers.
so.. 980x -> 4770k ?
or
980x -> ib-e at the end of the year?
Help?
Hopefully it will oc to 5Ghz on air with decent temps kind of like the 2500k. I also hope there will be a 2c4t chip that can be overclocked to the moon!
Wait for Ivy-E...
Hopefully it overclocks quite a bit better, considering it's built on revised 22nm tech process.Quote:

Probably Sandra2013 doesn't support FMA3 yet (only FMA4), so the IPC improvements are responsible for current perf. gain.Quote:

I was under impression that sisoft sandra was the 1st piece of desktop commercial software to support both FMA3(FMA4 on BD/PD) and AVX2.Quote:

edit2:
Found this on sisoft facebook page :), it definitely supports FMA3.
Quote:
We are pleased to announce the release of SP1 for SANDRA 2013! Because we managed to test Haswell (Crystal Well), we have some fixes and optimisations:
- AVX2 integer support (Multi-Media integer, Hashing)
- FMA3 float support (Multi-Media float/double, Memory/Cache bandwidth) [also works on Vishera]
- TSX (HLE/RTM) support (Transaction rate)
- eDRAM/L4 support (Memory, Cache, Latency)
SP6 for Sandra 2012 with all the fixes and enhancements of Sandra 2013 (but not new features) has also been published.
In the link I posted they explicitly mentioned FMA4, but no FMA3.Quote:

That's the strange part - float on AVX should be ~2x faster then double since both are executed by the same hardware using the same registers, and this is true for Ivy and Sandy). It's not clear why it's not true for Haswell. Latency is not important here.Quote:

Pretty sure I've read somewhere that Intel is taking a rigorous route of Apple [Macbooks] to fine tune motherboard specs down to the smallest parts to make them as efficient as possible.Quote:

Not sure who to trust: THG or FP.
We all knew Intel would come out and say the review is not entirely correct - this response is nothing but expected. Whether it actually says something about the review, each and everyone one of us can decide that for themselves. As far as I'm concerned: I've seen this type of message in the past and it always turned out that the performance figures with ES were (close to) spot on anyway.
Oh well, just an opinion ...

And I agree with everybody here... Intel needs to AT LEAST do a few HIGH PERFORMANCE chips with lots of cores, no integrated graphics and lots of cache. They could do a special Haswell chip just for the performance segment real easy... but considering the out-of-touch people running Intel, not gonna happen.
Oh heck ya ! :DQuote:

Graphene oxide in it's self is really expensive, $400+ per vial of it.
I know because I looked into it because I wanted to try using it in an inkjet or light scribe burner.
Some people sell it for cheap though but who knows the quality of this stuff.
I really wanted to play with that tech to make some super caps for my dfi nf2 :D.
Anyways...
This is a new socket right?
From my understanding so far, the cpu uses more watts then the 3770k.
But only because of the darned useless gpu thing in it (I wouldn't even use it for encoding h.264, I use lossless so it's kinda pointless...)
I wonder if you can disable the gpu.
But even you can't disable the gpu, clocking up the cpu it's self in theory should be more power efficient then the previous gen.
Then you got the new chipset shrink, awesome!
There's also this new integrated pwm thing, which I'm not so sure is a good thing though, but if peeps can clock it up then I guess it won't matter.
It might be a good cpu.
But then again, I'm still looking for a 6 core or better you know...
Great for consumers, not really anything special for pros or enthusiasts.
But then again supposedly it has a new instruction set or something I don't know.
I really hope that memory score is a fluke.
Seems worse then before.
:\
I'm looking forward to some of you guys playing with it :).
What i take from the benchmarks is that Steamroller will close the cpu gap between AMD and Intel more than Haswell will close the gpu gap between AMD and Intel. There's a real chance AMD leapfrogs Intel with gpu accelerated apps. i'm also very interested to see how Kaveri, first HSA CPU, will match against Haswell in legacy code.
The problem is that Kaveri "APUs" will be limited (so to say) to 3m/6thread configurations so at best it will be on par with FX8350(or on par with whatever PD based 4m part that runs at comparable clock- this is due to the fact that AMD promises 30% higher throughput versus previous generation so 6 "new" threads will equal 8 old ones).Quote:
Originally Posted by Piledriver
So in legacy code 3m/6T Kaveri can maybe come close to say 4570K Haswell I guess as 8350 should be on that level(if not a bit faster in x264 for example). In other stuff Haswell will probably still hold noticeable lead but common programs are already fast enough on current gen. of chips from both suppliers. It will boil down to what people use their PCs for. If there is software support for HSA than Kaveri will for sure be faster but we need to see those accelerated workloads hit the market first ,just the same as with AVX2(which intel is pushing).
There is no indication that Haswell uses more watts. It has 9% higher TDP due to 50% faster graphics (which can be switched off) and AVX2. When using AVX2 Haswell is up to 2x faster then Ivy, which I guess is a good trade-off for 9% higher TDP. Running old software Haswell should be more efficient than Ivy. Any way who cares about TDP - 3770K was rated 95W at the beginning.Quote:

Some stores already have it at $331... so basically it would retail at the same price that an i7 3770k is? Funny if that's the case.

Still waiting for 8 core cpus, I hope Intel can get their act together and release it by the time Broadwell cpus come out.
4C/8T cpus are totally useless in x264 and with pc games since it doesn't bring any improvement over regular quads.
AVX2-enabled version of x264 is in the work. Last commit was just 12 hours ago.Quote:

Graphene? Graphene is the wrong structure. It's diamond that is the same structure as what's been used in silicon and germanium wafers. The problem is so far people haven't figured out how to make decent sized wafers out of diamond.Quote:

The reason LN2 makes processors faster is mainly due to the lower temperatures dropping the resistance of the copper interconnects. Lower temperature is a mixed bag on the transistors themselves. Even after wafers are figured out there will need to be much more research into how production processes must be altered from how they are done to silicon to how they are done to diamond. Ex. It is much easier to grow silicon dioxide for insulators on silicon than it is to grow germanium dioxide for insulation on germanium.
The main benefit of diamond would actually be much cooler chips, since diamond has around 10x the heat conductivity of silicon.
I'll be waiting for the bug-free chipset before jumping on haswell...

So if your gaming experience is satisfying for you, there isnt much reason to upgrade. Its moot for you if haswell is 5% faster or 50% faster if you never are hold back by what you already got.
Our graphics go nowhere because consoles only evolve to the next platform every X amount of years.Quote:

Sorry but you don't need 6 cores to play Angry birds, games are still coming out in DX9.... I'm pretty happy we even get updates as often as we do, except they should unlock everything to keep pc enthusiasm going.
My second 3570K died after a few months under water i guess taking off the IHF is the signing of a death warrant in my case. The employee discount helps but i can only get a limited no of cpu's per year :( so moving back to 2500k/2600k it OC's very well and is very tolerant to voltage. I hope HSW is better in terms of tolerance scales but then again SOC's are often not.
I had a few 2600K CPUs with problems.. But those were after a year or so at constant 60-80% CPU load. Warranty to the rescue.
All 3770s are just humming along for now. No overclock, naturally.
How much voltage did you use? Im guessing the temps where quite good after delidding them and using water?Quote:

HandBrake to Get QuickSync Support
Two new DX extensions in Haswell GPU
http://www.legitreviews.com/news/15334/
http://www.anandtech.com/show/6863/i...ns-for-haswell
Quote:
The first of these extensions, called PixelSync, provides access to underlying hardware that allows programmers to properly composite partially transparent pixels without the need for an expensive sorting operation. Game developers have long awaited this 'ray casting' capability in order to more realistically render smoke, hair, windows, foliage, fences and other complex geometry and natural phenomena. InstantAccess, the second new extension, works by allowing physical memory to be written and read from either the CPU or from the built-in Intel HD Graphics.
Quote:
"The artists working on 'Grid 2' have been requesting this type of effect for years, and prior to this, it wasn?t possible to achieve it at a reasonable cost,? said Clive Moody, senior executive producer at Codemasters Racing. ?The fact that this capability will be available to millions of consumers on forthcoming 4th generation Intel Core processors is very exciting to us."
I still see no reason to upgrade my solid six core 980X.
As long as it doesn't finally just burn up, Intel is giving ZERO reason to upgrade the old high end 32nm parts.
I have never in my life had a CPU stay as competitive for as long as this little 980X that sits happily at 4Ghz on stock voltage. I can push it to 4.4Ghz if needed - easily.
Best computing investment ever.
So the deal is until AMD can someday magically compete for top total performance, Intel is never going to push the high end again? It is getting silly! :rolleyes:
Of course it's all only rumors at this point but word is IB-E may be >6 cores. Even at 6 cores it should be a (finally) worthy upgrade from gulftown. My 980x has been great to me too I'm just a little bored now. Watching everyone play on sb then ib while I sit on 1366. I'm ready for new goodies.
Had a similar notion before i let go of my 990X setup and getting a 3770K based system but after a lot of research i ended up getting a 3770K system. The most helpful being something from bittech let me see if i can find it.Quote:

The point being 3770K was a good alternative than the 990X, it has its problem being quad core but things are not all bad efficiency and power usage are much more improved. I was using a 1200W heavy unit to power the 990X beast which had already murdered a Glacialtech AX950 but now with the 3770K i am using a frugal 750W corsair unit.
Intel can not have a 6 core part that occupies the same TDP as a 4 core part in the same process. So they can either release a higher number of cores in the tick or increase die size which intel does not want. Quad cores will remain till a good enough octa AMD is made and from what i hear Intel has a backup plan even for Broadwell in terms 6 core processor not sure about HSW because of imposed TDP figures.
Thank you. I was thinking of "hanging out" on haswell until the end of the year when I did my real upgrade which is to add a third titan and ib-e. I had kind of given up on this but I might consider it now.
