6800K vs 6700K - Cores against Clocks!

2016-08-04
Oh speed well it all kinda started a few months back when I switched from my six core x79 platform towards a sky like CPU with a z170 platform as my workstation upgrade everybody flipped out everybody lost their x99 they said six core they said instead of this little dinky 6700 K four core CPU let's see if I made a big mistake the dark base 900 maybe the most innovative case of the year with a built-in Qi charger interior lighting tempered glass that can be installed on either side and a fully modular interior that can be inverted if you so desire be quiet stepping up their game check it out in the description below what's up guys I'm doing American axe and I've been so tempted to find out how much time I've been losing working on a fork or workstation PC versus a 6 core we're at workstation PC for Adobe applications the answer will surprise you as it did surprise me and so the battle begins between the 6700 K and a 6800 K skylake vs. Broadwell e fork or a thread versus 6 412 thread also look how tiny the size difference is a bit crazy now it is understood that an X 99 platform is more suited for encoding work for professional work for creative work anything that requires computational power because we have higher ram capacity on the motherboard we have more pci lanes on those processors and so my primary reason for switching to a z170 platform from the x79 platform was because i wanted to utilize the Intel 750 SSD which is the PCIe SSD as my boot drive which was not possible on the X 79 so I've just kind of stuck with it and it was been working great for me and so now I get to finally reveal to you if it's all been worth it or I should have gone with an X 99 from the very beginning in order to make the comparison even I am using the same 64 gigabyte of RAM kit from g.skill at 32 hundred megahertz a GTX 980 founders Edition and the same Kraken sixty-one cooler and a whole lot of patience for four days of testing so aside from testing stock to stock speeds between the two processors my 6700 K easily achieves 4.5 gigahertz at one point two four volts while I didn't get so lucky with the big guy that could only reach 4.2 gigahertz at one point four volts and starting with some generic understanding of the system performance we have 3dmark fire strike ultra with the six core machine performing 4% faster in Cinebench r15 the 6800 delivers a 34 percent better score both at stalk and overclocked and a 24 percent boost in OpenGL tests most likely due to higher cache so clearly more threads account for faster computation and that's exactly what we see in this collection with h.264 compression image editing heavy multitasking and OpenCL tests with the six core pulling ahead with a 28 percent boost for video compression and 15 percent increase for heavy multitasking while only 6 and 4% for image editing and OpenCL respectively and now my favorite part reel render tests in Adobe CC with real projects that we've published Adobe Premiere first so here I use my most recent edit the GTX 960 versus rx 480 and I have color adjustment layers applied with luma tree effects that are GPU accelerated this is very important because you can see both the CPU and the GPU being utilized while encoding but I wanted to make sure that GPU accelerated facts were not bottlenecking in my render so here are encoding times with and without lumetri effects this is very important again which gives you only a four second difference on my 60 second project which is not significant and therefore I left all my GPU accelerated effects in my testing and so are you guys ready to see the mothership of this entire video here we go so I exported a one three and a seven-minute timeline with both CPUs at stock and overclocked and the six core machine at stock speeds finished seven percent faster on the longest time line then the skylake cpu while only 8% faster when comparing overclock to overclock between these two processors it's also very interesting to see how my 6700 K at 4.5 gigahertz finished 3% faster compared to the six core at stock speeds then getting into After Effects I tested a camera track feature that analyzes the footage for tracking reference points onto which you can place tracking text and do all kinds of stuff and then warp stabiliser that analyzes the frames and smoothest everything out so here on my 11 second file regardless of clock speeds the 6700 K completed the analysis 15% faster than the six core machine very unusual result I'm happy to see that you know the four core machine with faster clock speeds performed better in After Effects for these particular tests versus a more core slower clock speeds and finally getting into some gaming there isn't that much of a big difference here the six core showed incremental performance improvement in CPU heavy titles up to six extra frames per second on average on an overclocked 6800 K in battlefield 4 and so the takeaway based on this testing is that the 6700 K is an impressive lordship I almost took it for granted there for a while thinking man I should have gone with a six core but with my overclock of 4.4 gigahertz I am out competing in encoding times compared to a 6800 K at stock speeds the Gazza goes up to three point eight gigahertz however if you can overclock the six core chip to past 4.2 gigahertz then you're lucky then it will give you a marginal you know 7% increase in 4k encoding compared to my overclocked four core machine but when you take into account pricing for each system and x99 platform will be significantly more expensive than a z170 platform and you have to just take into account and see if you will benefit for higher maximum memory capacity so like the next 99 can support up to 256 gigabytes versus z170 only 64 gigabytes you have to consider more pci lanes on the CPU itself if you're doing multi you and stuff like that but all these benefits will come at certain cost obviously if your future proofing however I am sticking with my sky like 6700 K for now because Adobe loves clock speeds and that's a fact any last words so yeah those are my findings very surprised and my findings to be honest thank you guys so much for watching this video that's it you're done can I go now
