Funny Discussion, some Infos are completely off, as a CPU the 5960x is far superior, 4 lane DDR 4 as a start. More power for less than 1/3 of the cost? certainly :D I completely agree that for 99% of the people around the 6700k bears more than enough power. At the level of both CPUs you are most certainly talking about a system with a dedicated GPU, so if you are going for power gaming 5820x is probably the way forward. And Multithreading is state of the art, you wont require 12 threads for a Game for a long time, but games today do use 12 or more threads, a good example would be Witcher 3.
It's higher counting iGPU, which should not be counted. CPUBoss has become shitty, started counting iGPU into ratiing
So how does CPUBoss say 5960X is winner when 6700K has a higher CPUBoss score? This site is so weird.
except that Vulkan and DX12 utilize all 8 threads. And people do far more than just GAME on a PC.
for the future, the 5960x will be better. Games are using more and more cores these days and the hyperthreading of the 6700k will only get you so far.
which one is beast for HD future gaming? Intel Core i7 6700K vs Intel Core i7 5960X (no money issue)
That doesn't mean it can't be used for gaming.
thing is Broadwell-E isnt built for gaming.
i m with 6700k, no game uses 8 core yet.
I'd say wait until Broadwell-E is out, and see how that alters the 5960X price. With Broadwell-E, you'll get 10 cores instead of 8. Alternatively, the 6700K is a solid chip, miles ahead of the first generation i7s (the early i7s were closer in performance to Core2 Quads than the i7s we have today). Either way, you will notice the difference, but you said 4 cores (and 8 threads) have always been more than capable for you, then the 6700K might be the better option. In terms of performance, it's more like 8 Core i7-960 cores when you can use the multithreaded horsepower of the chip.
Back when the I7-920 was release, i bought it. Its been 8 YEARS, and it still does everything I ask of it. Never a slow down, plays all the games, it was the best purchase I ever made, Having 4 cores and 8 threads with a good amount of RAM there isn't much I can not do. But it's time to upgrade and I am torn between these two. In my 25+ years working with PCs, buying the best you can afford has always been my rule. When it comes to PC components, YOU GET WHAT YOU PAY FOR has always been 100% true. I have never upgraded a PC that was less than 6 years old this one is 8 years old. But 1k for just the processor is kinda out there but I can see in the future when the extra cores and threads will be handy. I am looking at a deal at HP with the I7-5860X, with 16GB DDR4 RAM, Nvidia 970 4GB with other junk stuff 1GB HD, DVD, Wifi 11AC card, etc for around $1700 ish. Seems reasonably priced. Thoughts? I retired from the business a while ago, just want something that will last at least 5 years and up to 7 years if I get lucky. Thoughts?
Not true since the i7s use the same i5 clock speeds, but there's a 30% increase from SMT. They are all the same processor underneath, just the i3s run at slower speeds with more dud transistors.
This site is absolutely ridiculous.
i have a core i7 4790k and i use some of it for gaming and some for my mac osx virtual machine
Not in all cases are games more GPU extensive, most of the top IPs out there today, Guild Wars 2, Blade and souls and many other are incredibly CPU dependent, although I understand a good GPU will benefit from it too.
Well I have used the core I5 which functions is very latest and I’ve played games on it. http://strikeforceheroes.co/
well... by that logic, the 6700k still loses compared to most i5s or even i3 in certain cases
pretty much in this situation price isn't really supposed to be a big factor
https://youtu.be/49pZqu4h_jY?t=9m43s i7 5960x can overclock to 4.7GHz
Even though the 5960X is a beast, the 6700K wins in single core performance and multiple core performance up to 4 cores. Not many games and applications can even use the power of the 5960X's 8 cores. The 6700K wins.
nah
no way to compare the fifth generation is much better than the sixth one, so don't go so far i7 5820k which is with 6 core is so powerfull than i7 6700k which is with 4 core so what about to compare i7 5960x with 8 core with than weaker i7 6700k
I have to agree with ユキ 歌愛. From a gamer's perspective, the i7 6700k is a far better choice in terms of price to performance ratio but if you are just going to use it for gaming then the i5 6600k is a great deal as well. The 5960x is better suited for intensive multithreaded applications and or running multiple VM's simultaneously. They are both excellent processors but have different attributes that pertain to their specific markets.
Perhaps I'm not reading your comment right.. But the 6700K supports 64gb of RAM as well.
The price difference makes this comparison unbelievably silly.
