Yes, but not many apps take advantage of more than 4 cores. Intel should have figured out a way by now to take advantage of full TDP headroom for only the cores which are loaded. If anything it is these chips that should have the most aggressive Turbo since they have way more TDP headroom than Z97 chips. I think the reason Intel isn't enabling this is because if your 3930K could Turbo to 5Ghz on 2 cores, 4.5Ghz on 3, 4.2Ghz on 4, then people would buy that and not upgrade for 7-10 years. With weak Turbo today, they can claim that 5820K is faster than 3 year old 3960X.

Can you imagine 2 cores pulling 140Watts? Imagine how high the Vcore would have to be and that Intel would have to guarantee that such a high Vcore is safe for at least the warranty period.
Can someone actually compute the how high the Vcore would have to be for 2 HW cores at 4.7-5GHz to pull 140W?

I think HW-E is not worth is for people who already own a good DDR3 memory. If you can find a six core SB-E or IB-E for not more than a new 5820K I think that it's actually a much better deal. HW-E only brings 8% IPC uplift and it OCs worse on average how much worse I don't know let's say 5% then IB-E and 10% then SB-E, with such numbers you only have a tiny better change of having a faster CPU buying HW-E. It's a pass for me due to DDR4. It killed it for me.
Did someone test 2x4GB? I don't really need 16GB right now, I can add more memory letter when the prices become reasonable.
ps. I'm angry, there's literally 1 4930K on sale for a lot more than a new 5820K, why can't I buy used high-end equipment in that shithole called a country like residents of other more affluent countries for reasonable prices. And no one in Germany wants to ship to Poland.

Actualy Xplane 10, Anno 2070 and to a lesser extent F1 2013 are all running better without HT according to Hardware.fr review (excellent as usual, with tests that goes beyond the usual benches).

What this release did for me personally is convince me that CPUs are no longer worth anticipating and getting excited over. I can stick to the 3930K and upgrade GPUs for a painfully long time and not be missing much as far as game experience goes.
I have financial priorities that currently prevent me from springing on a full blown setup and in the past I'd be upset over not being able to snatch up the newest thing because I was missing out on a lot of performance. That's just not the case anymore. I can easily wait, presumably forever at the current pace of progress.

well that shows Xplane being faster on 4770k than 4670k so at least not worse. and in F1 2013 the difference is .8 fps at 90 fps which is margin of error.

at xbit HT has no issues with F1 2013. http://www.xbitlabs.com/articles/cpu/display/amd-fx-9590-9370_5.html#sect0

now F1 2012 certainly does not like HT. http://www.xbitlabs.com/articles/cpu/display/core-i5-4670k-4670-4570-4430_5.html#sect0

in Thief its only 2-3 fps difference so not worth disabling since I dont drop below 60 fps ever anyway.

 

[Enigmoid]

I'm rather pleasantly surprised at the efficiency of the chip. SB-E was significantly less efficient than SB. HW-E seems nearly as efficient as Haswell (with overall efficiency down because of the more power hungry LGA 2011 platform). Certainty nice if this is indicative of Haswell EP and EX in servers.

Surprising comment from TechReport:

"One product you'll probably want to avoid is the Core i7-5820K, which Intel has ruined by disabling a bunch of the PCI Express lanes. I swear, if there's a way to tune a knob or dial in order to gimp a CPU for the sake of product segmentation, Intel's product people will find that knob and turn it, no matter what. In this case, the Core i7-5820K loses the ability to host a dual-graphics setup with 16 lanes to each PCIe slot. Have fun explaining that one to your friend who popped $389 for a CPU and about the same for a fancy X99 motherboard, only to find that it's no better—not even in theory—than a 4790K for dual-GPU setups. This issue is more pressing now that AMD relies on PCI Express bandwidth for transferring CrossFire frames between GPUs."

It seemed six cores for under $400 would be exactly what every enthusiast wanted (including many in this thread who've already purchased the 5820), and the lack of PCIe lanes has never hurt Haswell, at least for dual-card setups.

Thoughts on AMD R9 290/X Crossfire and PCIe bandwidth limitations?

 

[NTMBK]

Gives us enough lanes for an x16 GPU and an x4 SSD. Who needs Crossfire.

 

[Sweepr]

Not a big deal according to AnandTech's review:

The 28 lanes of the i7-5820K has almost no effect on SLI gaming at 1080p. One question that will come from all sides is if the 28 lanes effects gaming. The CPU will cause an x16/x8 SLI configuration in two-way and x8/x8/x8 in three-way SLI, rather than the x16/x16 or x16/x16/x8. We tested at 1080p maximum settings with two GTX 770 Lightning GPUs, and found that the only benchmark that any significant difference was the average frame rates in Battlefield 4, which dropped from 110 FPS with the 5930K to 105 FPS with the 5820K. It makes sense that we should test this with 4K in the future.

Honestly I'd rather have a hexa-core chip with 28 PCIe lanes than another enthusiast quad-core chip with 40 PCIe lanes and likely lower clocks/higher TDP than a Core i7 4790K.

 

[Ylurien]

Best review I have found, bar none, for those interested in benchmarks for the 5820k, especially the gaming benchmarks section. Wish I could read the language to see what kind of cooling, etc. he is using.

http://nl.hardware.info/reviews/558...30k--5820k-haswell-e-review-eindelijk-8-cores

And let me just say: I get the love for the 5960x, but where the hell are all the reviews for the 5820k? At this time, I haven't found a single review that overclocked the 5820k! I imagine that these chips are binned differently from the 5960x, so extrapolating 5820k performance based on the 5960x is probably not accurate. Hence, we need people to start overclocking their 5820k CPUs stat! Get on it!

 

[Abwx]

well that shows Xplane being faster on 4770k than 4670k so at least not worse. and in F1 2013 the difference is .8 fps at 90 fps which is margin of error.

The score in Xplane is with HT deactivated according to the reviewer.

On another note that is not game related they say that using 4 memory channels anihilate the benefit of using DDR4, two channels seems the best set up overall.

That's a 34% increase for the 8350 and a 37% increase for the 7800.

 

[WhoBeDaPlaya]

It's not prime95 it's AVX/AVX2 instructions that increase CPU voltage so any software that use those instructions will also have the same effect on the CPU. Right now I don't know of any useful software that uses AVX much less AVX2 with FMA like newest revisions of IBT or prime95.

Doesn't HandBrake use AVX?

 

[Abwx]

Doesn't HandBrake use AVX?

Not sure for HB but Tech Report use a X264 XC with AVX2 implemented and allegedly FMA but seems to me that X264 coding is purely integer related and that both FMA and AVX1.0 are useless in this case.

[RussianSensation]

You're still thinking about it as a end user perspective, and not from a server perspective. Servers can use all the threads you can give them as load increases.

Yes, I understand. For those who use many threads and need as much RAM as possible, the density advantages and lower power usage of DDR4, coupled with a lower price point of 5820K and 2 more cores on the 5960X are a win. Also, I still think for those keeping a platform for 4-5 years, I would take 5820K and 8GB of DDR4. Once prices drop, one can always get more RAM. I can't think of any game that benefits from >8GB of RAM.

Having said that I think if Intel doesn't delay Skylake-K to 2016, then a 14nm i7 5770 without VIR could surprise us with overclocking beyond 5.2-5.3Ghz. The $299 price at MC for the 5820K is surely going to make many overclockers question the $279 4790K.

Can you imagine 2 cores pulling 140Watts? Imagine how high the Vcore would have to be and that Intel would have to guarantee that such a high Vcore is safe for at least the warranty period.
Can someone actually compute the how high the Vcore would have to be for 2 HW cores at 4.7-5GHz to pull 140W?

Doesn't have to be 2 cores and doesn't have to be 140W exact. I am saying Intel should use the headroom up to 140W to maximize turbo on 2/3/4/5/6 cores. I don't see why 5820K can't boost to 4.4Ghz on 2 cores given that someone running such a CPU is likely to have a potent enough cooler to deal with higher voltage and power.

 

[TreVader]

Haswell E turns out to be a dud for gamers, but thoroughly spanks the quad core i7s in anything productive.


I like the 5960X. Phase change or LN2 and you're in a new category of performance.



I mean really, all these quads are bragging about its 150 vs 140fps on the hex/octos. Who cares? This is 16 threads we're talking about.

His conclusion is hands down the most idiotic statement written in TechReport in the last 5 years. Does the author not realize that Z97 chips run dual cards at the same x8/x8 setup that the 5820K would? But you can even do x8/x8/x8 Tri-fire and incur maybe a 2-3% performance hit? With his logic no one should buy a 4790K either since it's even more gimped. Facepalm.

Regarding the reduced lanes on i7-5820K,

Compared to LGA 1150 chips with Z97 and M.2 ultra (x8 and x4 is all a person gets in that scenario), i7-5820K is pretty sweet with M.2 ultra plus three x 8 slots.

 

[cbn]

Already got a Microcenter ad in my inbox:

5820K is $299
5930K is $499
5960K is $899

Fry's in store price for i7-5820K is $344:

[OVerLoRDI]

The relatively affordable price of the 6 core/12T version (5820X @ $389) is an interesting option. Especially in the coming future, when cheaper (but still probably a fair bit more than socket 1150) motherboards and more affordable DDR4 prices come into play.

Indeed. I was curious about the 5820 until I saw the ddr4 prices... Ill hold off.

 

[SPBHM]

finally they made the 60X a good part, it clearly offers something more, while the older ones were just about a bigger price basically,

some of the OC results are extremely impressive, to think this thing have so much extra performance compared to a 4670K or something is great,
and the 5820K is very well positioned CPU, it have all the right ingredients to become the new 920 (but the 4790K is a strong argument against it), for now the DDR4 prices are a big consideration, but in a year I think the biggest cost disadvantage compared to the mainstream platform is going to be the motherboard prices, but at the end of the day some people are buying $200 MBs for 1150, so why not just go with 2011 v3?

 

[cbn]

but at the end of the day some people are buying $200 MBs for 1150, so why not just go with 2011 v3?

Agreed. IMO low end X99 basically obsoletes high end Z97 (the exception being Mini-ITX)

(As far as the ram costs go, I'm seeing only a $30 to $40 delta at the 2 x 4GB gamer level. That doesn't really seem like much of a difference)
