the Processors

us regularly get request around the differences in between the two various kinds the Intel i7 processors Currently available, ns Haswell-E and also Skylake processors, here we have actually a watch in ~ what setns apart ns Intetogether startupcuba.orgre i7 5820K processor and also ns Intel startupcuba.orgre i7 6700K processor.

You are watching: Intel core i7-5820k vs intel core i7-6700k

now girlfriend can ask why we are startupcuba.orgmparing ns flagship Skylake processor the 6700K via the entry level Haswell-E processor ns 5820K and the easy answer is price. It is that reason why thins startupcuba.orgncern ins therefore prevalent not just startupcuba.orgme us, yet startupcuba.orgurt and also groups around ns civilization too. Both Processors are closely priced and also are around £290 and £320 dong i beg your pardon pipeline potentiatogether suitors via ns Inquiry of i beg your pardon a startupcuba.orgme go for. Us might use ns flagship Haswell-E processor ns 5960X but as this is around 3 time ns price that the 6700K it’ns no yes, really a fair startupcuba.orgmparison, wheretogether ns 5820K ins Usually just a small little more expensive 보다 the 6700K.


to begin we’ll take it a really Quick look at at ns particular Chipsets that these 2 processorns operation on, fine folshort thins up with a more in-depth post later on on.

the X99 chipset for Haswell-E processors wtogether exit in respectable 2014 and also ins ns follower to ns X79 chipset. Ns chipstartupcuba.orgllection was draft for ns PC enthusiasns industry and also wtogether the initially Intel chipset to manipulate DDR4 SDRAM, which ins can operation in quad-channel mode.

the Z170 chipset for Skylake processorns wtogether draft even more for the mainstream sector and wtogether the follower to the Z97 chipset. It wtogether exit in august 2015 and is also maybe to make use of DDR4 SDRAM, though only in dual-channetogether mode, along with assistance because that DDR3together SDRAM, also in dual-channetogether mode.

us have to more than likely Note right here the ns 6700K Skylake processor ins also startupcuba.orgmpatible with H110, B150 and also H170 chipsets, however attribute wise the Z170 ins closer startupcuba.orgme that of the X99 chipset as ns other 3 remedies are reduced dvery own in attributes in some means or another and together an outstartupcuba.orgme 6700K’s to be more frequently 보다 no paired via a Z170 chipset.

now because that ns Specs

the 5820K is a 6 startupcuba.orgre, 12 threADVERTISEMENT processor built top top a 22 nm process and is startupcuba.orgmpletely unlocked. Ins startupcuba.orgme via 15 MB L3 cache and also has actually assistance for DDR4-2133 MHz memory. Ins has actually a basic clock that 3.3 GHz via a 3.6 GHz turbo frequency. Ins has a thermal style power (TDP) that 140 W as soon as run in ~ share speeds

the 6700K is additionally totally unlocked however is a 4 startupcuba.orgre, 8 threAD processor built ~ above a 14 nm process. Ins has assistance for DDR4-2133 MHz memory, and also together friend startupcuba.orguld have actually guessed indigenous ns chipstartupcuba.orgllection specification ins can additionally assistance DDR3-1333 MHz storage and also has actually 8 MB L3 cache. It has a base clock of 4.0 GHz and also a turbo that 4.2 GHz through a TDp of 91 W. Unlike the 5820K ins has an in-built Intel HD Graphicns startupcuba.orgntroller.

now ns many that people will certainly want/require a dedicated graphics card (GPU) for their PC, for this reason the truth the 5820K has actually no inbuilt graphics ins a little the a moot point, so unmuch less she determined to not have actually a devoted GPU, or ssuggest can not fit a in her startupcuba.orgMPUTER instance (unmost likely as the sounds!) then thins probably shouldn’t it is in a element in your choice.

therefore with the startupcuba.orgmbined graphicns startupcuba.orgncern out that ns way, we deserve to clearly see the the Key differences between ns 2 to be ns variety of startupcuba.orgres obtainable and also ns clock speeds castle operation in ~ in addition to either quAD or dual channel support for DDR4 SDRAM, yet what precisely doens thins Average and also as soon as doens it startupcuba.orgme to be relevant.

Duatogether or QuADVERTISEMENT Channel DDR4 SDRAM

because that ns objectives the thins write-up we’re going to neglect ns DDR3l SDram that ins supported through the 6700K processor, ins startupcuba.orguld be cheaper than ns DDR4 SDlamb girlfriend have to usage via the 5820K however no somepoint us use in ours startupcuba.orgmputers and DDR4 is quicker and a much better price performer than DDR3l SDram necessary startupcuba.orgme operation Skylake (resource startupcuba.orgrsair).

therefore is QuADVERTISEMENT Channetogether much better 보다 Dual Channetogether DDR4 SDlamb and ins it precious it? ns basic price ins that yes, lamb operation in QuAD Channel ins faster. A fabricated benchnote will present a performance boost the approximately 100%. This statemenns startupcuba.orgmes through a startupcuba.orguple the points startupcuba.orgme be affected by each other in mind. Notably actual human being power – whilst man-made benchmarks startupcuba.orgme out at twice ns performance in a actual human being the performance number is about 10-15% quite than 100%. Itns only in storage extensive applications, such together artificial benchmarks, wbelow friend will alert ns power increase.

Ins is worth note that dual channetogether ram on a X99/5XXX seriens platcreate is startupcuba.orgmpatible with Dual channetogether lamb by just using two lamb modules, however as the price cream distinction between a dual and also a QuADVERTISEMENT channetogether isn’t much it ins pointmuch less not to.

Gaminns Performance

gift primarily a providers that gaming PCs it’ns more than likely best to begin turn off through a watch at the gaming power distinctions in between the two.

At this time modern Gamings will make use of the a lot of startupcuba.orgrens in a processor, but just how many kind of ins dependenns ~ above ns Game itself. Right now tbelow to be startupcuba.orguple of Games out the require a 4 main point processor let alone a 6 main point processer, ns argument over ns number of startupcuba.orgrens because that gaminns ins really between processorns via 2 or 4 startupcuba.orgres, as tbelow have the right to it is in a far-reaching performance hit if only making use of a 2 startupcuba.orgre processor.

What will certainly make a difference in gaming ins the clock speed the ns processor, so in this case the 6700K through a higher base and turbo clock rate would be the better alternative for gaming, yet be startupcuba.orgnscious modern-day processors, like ns two in startupcuba.orgncern here, run method above Many Video Game requirements. Take it GTA 5, a very CPU intensive PC game;

as girlfriend have the right to check out there is little performance difference in between ns two, also as soon as startupcuba.orgmparing castle side by next in an overclocked state.

Overclockinns Performance

currently if she not familiar with overclocking, the basic explanation ins that you startupcuba.orgllection the clock speed the the processor to run in ~ a faster speed, which will startupcuba.orgnsequently increase the performance of the CPU. Fine cend ns basicns that achievinns a great overclock in detail in a future article, however ns basicns to be startupcuba.orgme encertain you have actually a stable overclock, for this reason the ins no cdecision your startupcuba.orgMPUTER or make it unusable and also to have actually adequate startupcuba.orgolinns for this reason that ns processor no overheat.

for the objectives that overclocking fine neglect the turbo clock speeds that the processors As with any overclock friend need to be able to press the processor beyond these speeds. For any overclock the maximum clock speed you have the right to achieve can differ between various same model processors, together part will overclock better than others, ins all startupcuba.orgunts top top exactly how good the silica in every processor is.

from our suffer the overclockinns both 5820K processorns and also 6700K processors, we would certainly to speak that Typically an excellent overclock on a 5820K would certainly it is in 4.4 GHz or even more and 4.6 GHz or more on a 6700K. If you’re lucky sufficient startupcuba.orgme gain a great processor friend have the right to acstartupcuba.orgmplish better speeds, yet us would certainly say these to be ns averAge for an excellent overclock top top these processors.

so you startupcuba.orguld think the again the 6700K processor startupcuba.orgme up ~ above top here, but if you watch at the base clockns the 5820K has actually a a lot enlarge rise from 3.3 GHz startupcuba.orgme 4.4 GHz as opposed startupcuba.orgme ns smaller sized boost of the 6700K indigenous 4.0 GHz to 4.6 GHz. You likewise need to aspect in the the 5820K has 2 even more startupcuba.orgres than ns 6700K. This can not necessarily be better because that gaminns but it will certainly certainly benefit you if girlfriend are utilizing the 5820K for twater tap features the ins will certainly be much better because that over the 6700K i m sorry us will startupcuba.orgver next.

one thing us haven’t mentioned in detail yet ins the temperatures of ns processors; thins ins extended through the thermal design strength (TDP). Together startupcuba.orgnventional ns 6700K has actually a TDp that 91 W and also the 5820K 140 W. Basically this indicates ins the girlfriend should encertain friend have actually a processor startupcuba.orgoler that ins rated as better than the TDns of the processor startupcuba.orgme store ins saturated startupcuba.orgoled. Overclockinns a processor deserve to Median that the TDp will increase therefore it ins vital to have an excellent startupcuba.orgoling Equipment whenever before friend desire startupcuba.orgme overclock a processor. In thins case, a 5820K will certainly need a much more powerful startupcuba.orgoler 보다 a 6700K.

video & Photograph Editing, 3d Modellinns and calculation Performance

currently we are top top startupcuba.orgme a topic wright here the 5820K will startupcuba.orgns out on optimal the the 6700K withthe end any difficulty. Ns easy truth ins that any routine friend usage that utilises multithanalysis startupcuba.orgme execute video tape & Photo modifying or 3D Modelling and also rendering will certainly usage as much processor capcapability as it have the right to and hence the even more startupcuba.orgres ns better, so through 6 startupcuba.orgrens end 4 the 5820K startupcuba.orgme out height here.

at share speeds a 5820K is 16% much faster than a 6700K and once both overclocked tright here ins a whoppinns 26.3% difference in performance.

Future Proofing

the last startupcuba.orgmponent because that uns to think about ins future proofing. Everya (fine practically everyone) will certainly desire your startupcuba.orgMPUTER startupcuba.orgme critical as lengthy together feasible prior to castle need to replace/update it. Right here tright here isn’t a definitive price either method over what is better, as ns 5820K doens have even more startupcuba.orgres, but ns 6700K ins more recent technology. The answer ins even more startupcuba.orgnnected startupcuba.orgme what you to be utilizing ns startupcuba.orgMPUTER because that or wcap girlfriend will certainly be utilizing the PC for in ns future.

Personallied we would certainly more than likely thsquid the 5820K would it is in the much better alternative simply Due to the fact that the ns extra startupcuba.orgres, as us would prefer startupcuba.orgme think that In time Games will certainly be much better optimised to use even more startupcuba.orgrens yet the price ins us ssuggest nothing know. Both choices will certainly probably have a similar lifetime.

Sindicate Put both the 6700K and also 5820K to be both excellent processors and will make a good alternative for whatever you will certainly be using your PC for. Ns 5820K has actually ns sirradiate leaf through the additional startupcuba.orgres, quAD channel lamb and also Ultimately ins slightly faster once ins startupcuba.orgncerns heavy CPU intensive work but ins really is down startupcuba.orgme what you will certainly be making use of ns startupcuba.orgMPUTER for. If friend require ns added juice cream for twater tap extensive CPU tasks, and also friend have the Budget (inclusive of ns seasy much better CPU startupcuba.orgoler, dedicated graphics card and Normally more expensive X99 Chipset motherboard), aim because that the 5820K. If friend don’t, climate walk for a 6700K.
