6700k 4.5Ghz vs 5820K 4.5ghz

Yeah i am sure techspot test in exactly same scene as me :rolleyes:
You can try it

Fallout4 Save games:
first scene
http://www.ulozto.net/xxfqHqjH/save...19-2-fos#_ga=1.73052947.1857298745.1440807563

Btw if anyone want try It you must USE 80FOV(i think its default) in first scene and 90FOV in second and 1920x1080 resolution and max details..FOV have impact on cpu performance..

Why would it matter that they didn't use your exact test? The did a suitable test using a variety of cpu's and gpu's under good test conditions and showed that the game is not cpu limited in the fashion you claim it is. They did show far greater gains to be had at 1080p/ultra from changing from an upper mid range card (970) to a high end card (980ti) whilst running a fast cpu 6700k @ 4Ghz then was generated by a 500Mhz clock difference and ipc improvements from a 4770k at 3.5Ghz to a 6700k at 4Ghz

digital foundry tests 6700k vs 5820k and 5960x

The clip shows that the Skylake chip is marginally better for gaming. The 5820K blasts it out of the water for everything else.

For roughly the same price the 5820k is by far the better all rounder :)
 
For productivity the 5820K is not 50% faster than 6700K as many will assume, first the IPC is higher on the 6700K secondly it is more likely that you will get high frequency with the 6700K (let say 4.3 for the 5820K and 4.6 for the 6700K), also not all applications that use 12 threads have 100% perfect scaling, so all this add up and the end result is going to make the 5820K more like 10-20% faster than the 6700K, not to mention that the applications that use 1-4 cores the 6700K is going to held a lead over the 5820K.

So pretty much what I stated at the start of the thread

I'll take proper reviews at a minimum res of 1080p showing 1-2 fps difference between the 6700k and 5820k in games where the 6700k wins out with a 200mhz overclock advantage

http://www.kitguru.net/components/cpu/luke-hill/intel-core-i7-6700k-i5-6600k-skylake-cpu-review/8/

Of course where an app can make use of the 12 threads of the 5820k it spanks the faster per core 6700k by a far more appreciable margin...

http://www.kitguru.net/components/cpu/luke-hill/intel-core-i7-6700k-i5-6600k-skylake-cpu-review/5/

Where Skylake excels it only marginally pulls ahead where Haswell-E excels it spanks Skylake 4C/8T performance.

Its not going to be 50% no. Its around a 30% performance increase clock for clock for tasks utilising the full 12 threads vs the 8. Gaming performance is a little sceptical to be honest. Some videos say the 6700k is faster, some say not.

My 5930k runs fine at 4.5ghz, 4.7ghz and will even do 4.95ghz under 1.45v. So they still clock well. Infact the vast majority will do 4.5ghz atleast.

It certainly helps me for multi-threaded use. Like i said before its also nice to run applications using the two cores, virus scan etc. While gaming with no problems.

lol @ the guy with the 5820k crying his eyes out :D

Yes I'm beside myself that my CPU that was released a year a year before Skylake and which cost me less than £300 is beaten by 1- 2 fps in some games by a 6700K that for most of its life has cost £320+ Ill just have to console myself as I render some video footage at great speed whilst being despondent at my upgrade options down the line to a eight or ten core 14nm chip whilst all the cool kids with Z170 boards can look forward to yet another four core eight thread top end I7 chip based on the same design as Skylake at the same node size that's going to overclock pretty much identically to a 6700K but which comes with an improved iGPU that's of no use to pretty much anyone on a high end I7.

Oh my wont someone think of all those poor X99 owners the inhumanity!
 
You're not going to be held back in gaming with either chip tbh. I've not found my 5820k at 4.5ghz a downgrade from the 4790k I had at 4.7ghz. Cooler running by a fair bit, which is also the case with skylake cpu's. Intel must have finally got the thermal paste recipe right.:D
 
Clearly if you just mainly game the 6700k is the best gaming cpu.

Its marginally better in some games and at least now it actually costs less with a Z170 board than a comparable 5820k/X99 combo

for most of its life, in the UK, this hasn't necessarily been the case.

I would still recommend people consider X99 as the platform has more flexibility and longevity than Z170 as it has more PCI-E lanes (CPU dependant) and Z170 will leave you stuck with a 4 core 8 threaded CPU. When Cannonlake releases and becomes the consumer top end mainstream part we will be onto 6+ cores and you could see a repeat of the Q6600/E8400 scenario where although the part with less cores (the dual core E8400) was better on release compared to the Q6600 due to the higher clocks per core the Q6600 was shown to have far more longevity as it had more cores to utilise as things moved on...
 
Came from a [email protected] to a [email protected] (returned as I saw hardly any difference from the 2600k in real world use and gaming was in line with margin of error (Cost of upgrade to 6700k £955) and now a 5930k... Reality time now..


2600k to 6700k for gaming on a single 980ti at 3440x1440 a waste of money and time. SLI saw about a 10% increase to the 6700k... I don't like SLI .. so it went back for a refund.


Still wanted to upgrade so went 5930K from the 2600k. Overall everything feels smoother and runs just as well for gaming as the 6700k and 2600k on a single 980ti at 3440x1440. BUT the real improvements that made this worth its money was every other application and general desktop use feels more snappy and more responsive.


Now reality time again for people on 4 cores and if you have an i7 with HT so 4c/8t games are starting to use more cores and application. Check out the Division for one that uses more than 4 real cores not just HT. Also Nvidia users will find that the drivers will use a real core for itself that improves performance so people with more than 4 cores get a boost in games that support more than 4 real cores not HT.


Now my use of the PC I like to game on it and also like to do a lot of multi tasking and tasks that can strain the CPU a lot, so the 6 cores wins for me in that use. If you game only and not a power user get a skylake if you really want them 1-5 extra frames in real world use, if you are a power user 6 cores+ cpus are for you now, or you will be very disappointing with skylake.


You guys can argue about this till you go blue really. I have been threw this and seen the real world scenarios played out on cpu bound games FSX (4 cores used only) on all 3 cpus and reality is they all are pretty good for cpu limited low core use games (4 core and under)..


Now if you want to future proof and have been in computing a while, you will know more cores are always better and will always come into play in the future.. as we saw from dual core to quad core... and guess what people cried foul back then too saying a dual core was enough for games and they even showed they were faster in some games because the dual cores clocked higher than the quads... move on a few months and maybe a year or 2 ... dual core systems for gaming became obsolete because quad cores became the standard .... Guess what's happening soon ?


Skylake is a hard sell and even Intel have realised this but they are trying to catch out the market that doesn't understand technology or are new to it and have not seen the history of what happens as technology changes. OR are just not power users and want to game only on their computers and do general stuff that even a single core system can do well.

NOW before all you people with skylake cry foul... yes I mean you Dave... go read up a little and check the history regarding core use in games and how the changes come into place.

Also all you people with Skylake and are none power professional users of a computer should be happy with what you have as they are great gaming cpus, now you forget some of us here are power professional users too and found out that skylake wasn't enough of an upgrade from our previous highend systems... This is why we went X99 and also dropped the IGPU that as power professional users we don't use but we pay for it.. One thing that annoyed me about SandyBridge was this IGPU that was useless to me but it was sat there in my cpu using power and creating heat even when disabled and I paid for it to do these things that annoy me as I don't use it. They (intel/AMD) really should be making SKUs that don't have the IGPU if we don't want them or have them laser cut on the die so they are not electrically connected.. This sku could have been aimed at people like me and Intel could have saved some money by using chips with dead IGPUs that some of us didn't want in the first place... win win for me and Intel.. but they are to busy trying to be the next graphics card company...


This is my view on the CPU situation we are all in right now. The real issue is CPU progress has come to that point again where more cores are going to be added until they change from silicon and move to a new material as they did in the past, "silicon" as we know it has changed a good few times and it may change again to allow the new types of chips again with again more cores and higher speeds, for now as Intel has told us cpus are going to get slower, what they mean is the GHZ (clock speed) and to combat this they will add more cores until they move away from silicon or change it to a new recipe type again as they have done many times. Moore's Law is over with guys and girls and that's the reality and has been for a few years now.. Sad to see it go as CPUs were my favorite component in computers..


Now for professional use intel has Xeon 18 core/36 thread cpus which are the best they make currently.. so if you really want more cpu power in a desktop get a motherboard with dual cpu sockets and stick two of them bad boys in for 36 cores and 72 threads.. but be prepared to sell your cars, remortgage your home or sell the kids to Angelina Jolie or Madonna .... but remember for gaming they are useless... this is for power professional users only.


Enjoy what you use from Skylake to Haswell-E for gaming they really are no different in real world use. Even my old 2600k that I sold is dearly missed as it was just as good as these new chips for gaming.

still the 6700K clock better, and it is also a 91w vs 140w so less cooling requirements.

I am planing to buy a new CPU+mobo+ram to replace my aging x58(that i have from 2009 lol), and I am between the 5820K and 6700K, and I need it for productivity (photo editing & maps with extremity large rez and many layers and, my x5650 can barely cope), that means that I can make use all of the 12 threads of the 5820K so the 5820K sounds like a logical choice for me. But in order to save cost I will keep the same cpu cooler (Prolimatech Megahelms that I have from 2009) which I believe will have a hard time cooling the 5820K pass the 4.2-4.3GHz, but the 6700K is a 91w cpu and I think I will not have any trouble going 4.6GHz.

So according to my calculations (higher frequency)+(higher IPC)+(NOT100% perfect scaling across the 12 threads) that makes the 5820K 5-10% at best faster than the 6700K(in my case obviously). + the fact that on the applications that use 1-4 cores the 6700K is a clear winner.

So I think I am going to get the 6700K but still I am not 100% sure yet.
 
If SLI netted you 10% performance. Something was wrong.

10% better scaling over 2600k in SLI.. So basically 10% more frames with the 6700k in SLI over the 2600k in SLI. This I put down to gen2 (SandyBridge) to gen3 (SKylake) pcie and just a newer architecture with skylake that produced better SLI results. In Single card configuration there was no difference, all in margins of error.

Its not quite as simple as saying that because the Skylake CPU has a lower TDP then Haswell-E that it necessarily easier to cool. SKylake has the same **** thermal past between the die and IHS that Intel use on consumer CPU's vs the soldered 'Enthusiast' chips. Also because the Skylake die is so small compared to Haswell-E the heat density is greater (ie heat per unit area) which can cause issues.

You're looking to upgrade from an 'Enthusiast' platform X58 board which you have presumably upgraded down the line to a hex core Zeon.

I'm going to be blunt and say that this should be a big hint towards you're next purchase. You could have spent a little less in 2009 and bought a 1156 mother board and I7 860 or similar but this would have lasted you far less time than your X58 setup which has allowed you to eek out a lot more life.

If you want your next system to last you 6 - 7 years for 'productivity' use DO NOT buy a Z170 setup as it will cost you more £££ down the line when you realise that actually you might like 6+ cores again...

On Z170 your stuck with quad core CPU's
 
My 5930K runs cooler than my 2600K even when both are overclocked or at stock.. On the same cooler I used for both. Skylake ran pretty cool too from memory, never noticed anything strange temps wise.

Skylake is still using TIM , Haswell-E uses solder as did the SandyBridge 2600k.

only when IvyBridge came out they used TIM for their mainstream chips, before that they were all soldered too.

I couldn't agree more to be honest.

Although now(in 2016) the 6700K looks a bit better choice for me, but in the long run the x99 sounds the way to go. The real question now.... we will be around in 6 - 7 years? I mean WW3 is about to come :eek:
