i7 8700k vs i7 6800k

[zindan]

can’t find a lot of comparison between these two. what can u guys tell me? there is a 250$ price difference where I live. (6800k is cheaper)

 

for gaming which one is the best and how big a diff is there?

They are 2 very different CPUs.  The 6800K is an X99 extreme edition CPU and the 8700K is a mainstream Core CPU.

For Gaming the 8700k is superior for a number of reason.

Higher OC

Newer platform

Probably cheaper when taking MOBO into account as X99 are $$$

Here is a comparison between the two with a few basic benchmarks http://cpu.userbenchmark.com/Compare/Intel-Core-i7-8700K-vs-Intel-Core-i7-6800K/3937vs3607 and another that has a few value to performance charts, https://www.cpubenchmark.net/compare/Intel-Core-i7-6800K-vs-Intel-Core-i7-8700K/2785vs3098.

 

Hope this helps

did you factor in the probably more expensive motherboards for the 6800k?
IPCs are probably worse on the 6800k and you can't push it that much oc wise, but for that price difference it is pretty decent

[porina]

Depends on how the games respond to clock vs cores. The 6800k without OC is slower than the 8700k at stock, not counting architecture updates between them. Broadwell was not a good overclocking generation either. On that note, a Ryzen 2600(X) might even be comparable or better than 6800k so consider that also.

 

Where the 6800k might win is if you do heavy compute workloads, as its extra ram channels could help there, but this is a niche use case.

[Princess Luna]

i7 8700K is superior in every way except for memory bandwidth if you use all 4 channels and pci-e lanes.

[zindan]

thank you everyone

The 6800K has slightly worse IPC, and achievable clocks are lower across the board.

It does have more native PCIe lanes, and more memory channels (more bandwidth for tasks that like that).

If u have 1080p  144 Hz monitor with gtx 1080ti or Titian co   and  u need a CPU to run the most demanding game at 144 FPS then 8700k is the best available now but u u have a 1080ti or Titian xp plus a 4k TV or monitor then save some cash and get the 6800k cos at 4k is gpu target

-platform costs are different obviously , as it's x99 vs z370

 

8700k

-higher frequency potential and higher stock clock speeds

-slightly higher IPC on average

-less heat

-lower power consumption ?

-newer features

-more/faster chipset pcie lanes ( although kind of irrelevant )

-more native usb 3.0 ports

-less power hungry chipset ?

-higher supported memory speeds (although irrelevant because you'll probably use XMP anyway )

-support for TSX , TXT , MPX and SGX extensions

-IGPU with 4k netflix support

6800k

-quad channel ddr4 ( vs dual channel )

-better temperatures because of solder instead of value toothpaste

-more pcie lanes

-more native sata 6Gbps ports

-potential upgrade path to 10 core 6950x or 24 core xeon

-cheaper in your case

-more cache

-healthy second hand market for x99

-more memory ( 128GB vs 64 GB )

-x99 c00l Kids club /s

6800k is not Solder'd, its just a larger heat spreader that helps the lower temps. 

 

Overall @zindan  the 8700k is the better CPU, but not for 250$. Id go with a 5930k IMO if you can find one for the same as the 6800k, but other then that go with the 6800k IF you can find a decent X99 Motherboard and 4 sticks of Ram.

6800k , along with all broadwell-E chips is soldered . The outrage really started when intel used paste on x299 . In fact , here's a link to der8bauer deliding a 6950x , which is the same chip

This is only partially true and a bit misleading. 

 

i7 6800k has more direct CPU PCIE lanes but they are plastered onto x99 platform which in itself has only 8 PCIE 2.0 lanes.

 

Meanwhile, the 8700k is on Z370 which has 24 PCIE 3.0 chipset lanes.

 

To sum it up:

 

i7 6800k: 28 CPU PCIE Lanes 3.0 + 8 PCIE Lanes 2.0 from chipset

i7 8700k: 16 CPU PCIE Lanes 3.0 + 24 PCIE Lanes 3.0 from chipset

 

Since neither CPU will allow you to go for x16/x16 on the GPU, I wouldn't really say that 6800k has the advantage here. And if you are not planning on going for dual GPU then it matters even less which lanes are from CPU and which from chipset, making the 8700k's advantage even larger.

 

If you wanna go for x99, go for i7 6850k and up. You know, when Intel was bold enough to put 40 PCIE Lanes on a 6-core CPU.

yes and no . I did mention the chipset pcie lanes . Problem is the latency on those chipset lanes is quite a bit worse than the CPU pcie lanes.

Okay, I give you that, I did not account for limited bandwith in chipset lanes. It doesn't really change my opinion on the last part though, having i7 6850k here would make a much sexier comparison

[zindan]

thank you guys.

[TekZappa]

I have an 6800k, but i recommend the 8700k. Its an overall better Cpu and x99 boards are a dead end regarding future upgrades.

That price diference is crazy, where i live they are about the same price, the 8700k is 30$ more expensive.

The 1151 socket is, I guess.

I'm just saying that there is a high probability that i7 8700k will be the only CPU you can put on the Z370 chipset. 

 

Who cares if the socket is alive if you have to change motherboard every single time? Do you think that i7 7700k owners felt like their socket is alive when 8700k launched and they learned that they have to buy a new mobo if they want to upgrade?

kek.

[Biggerboot]

I think Ryzen 2600x would make more sense than a 6800k, but that's just going on our prices/availability.  If the entirety of your 6800k build is a fair bit cheaper, better off going that route.  They would perform about the same in theory.
