Z170 6700K vs X99 6800K

Harsh Kumawat · May 31, 2016

Which is better for a gaming scenario and maybe occasional Twitch / YouTube streaming but not a lot of video editing or rendering? Price isn't too big of a concern.

Thanks in advance community!

There is no "6800k".

DonkeyOatie · May 31, 2016

In pure gaming, which is almost entirely four core or fewer load, the extra 300 to 500Mhz of speed of the 6700K and the generational difference in IPC will tell, even with Twitch/streaming, which the Hyperthreading will handle comfortably.

Even so, in many circumstances, the difference will be unimportant. 120 vs 135 FPS is meaningless in most situations, as is 35FPS vs 39FPS.

In addition, your choice of GPU and display resolution could make the comparison moot too.

The 6800K is more 'flexible' if you change your mind and decide to do rendering and may have benefits when DX 12 is generally used.

DonkeyOatie :

Thanks for the reply and thanks for the information it was really helpful! I'll probably go with a 6700K most likely or maybe the 6800K if any future benchmarks change my mind.

Just for gaming, streaming and such a 6700k is indeed the better choice. The extra cores and threads of the X99 CPUs are very useful when you're doing stuff like editing and rendering 4K video on a regular basis (which is why all the big YT tech channels have at least one machine with one of these), but a consumer-grade i7 will handle simultaneous gaming and streaming more than fine.

Woops, thanks mate

for just gaming and multitasking the i5 is all you need the i5 you can stream with as well on twitch. The i5 will give you pretty much the same fps as the i7. The only thing the i7 is better for if you create content for youtube, and stuff and you need to make sure to get your videos uploaded daily. However you can still render on the i5 just not as fast.

They were unaware of the new Broadwell-E - release at Computex (It was only a few days before the post) Timeline matters with some threads. They were answering to the best of their knowledge and the later acknowledged their mistake.

We all make mistakes.

Mr Kagouris :

Yes, there is.

Btw, pretty lame ogre animation.

Rendering is done on GPUs (unless you're noobish and force it to be done by the CPU).

Mr Kagouris · Jul 5, 2016

gewinnste :

Then why doesn't everyone just use Intel Pentiums with a couple GTX Titan Xs instead of investing in high end CPUs? Oh right, because the GPU isn't the only factor and not all the rendering is done via hardware acceleration.

What? As far as I know with GTX cards you can only accelerate with a GPU but the bulk is done by the CPU. Is that right? I'm mostly talking about Adobe suite.

gewinnste · Jul 6, 2016

Mr Kagouris :

Sure, not all, but more and more. In the old days, you couldn't use GTX cards for rendering but now you can do that. E.g. blender and some computation-heavy effects in Photoshop (from 6 on, I think) can be done exclusively on the GPU. In general, the trend is to use graphics cards, and not only Teslas or Quadros, for GPGPU stuff. OpenCL is becoming more popular and so for highly parallelizable general purpose calculations, not only for graphics applications, GTX cards will be super nice. As expected, however, Nvidia limped the double precision performance of GTX cards, so they can still sell their insanely expensive Teslas for scientific purposes and if you need DP then a GTX won't cut it, sadly.

Btw, "hardware acceleration" just means that everything is shoved from the CPU to the GPU. It doesn't mean that the GPU helps - it does all the work.

P.S. In your graph, the task is exclusively done on the CPU, so, of course, there is such a big difference in performance. For effects in PS that are "GPU accelerated" you'd see practically no difference.

"Btw, "hardware acceleration" just means that everything is shoved from the CPU to the GPU. It doesn't mean that the GPU helps - it does all the work."

I'm pretty sure in adobe PP GPU acceleration only help with certain effects but the main compression is still all done by the CPU.

jtk2515 :

Yes, that's what I said above - calculation heavy effects.

Mr Kagouris · Jul 8, 2016

No, you said that the GPU does ALL the work, not only calculation heavy effects, which is not accurate at all.

BrownRecluse27 · Jul 11, 2016

I really only use my rigs for gaming but I know that rts games will push your cpu harder then your gpu a lot of the time. It would seem to me that they both work together and the app/game decides what it wants to use the most.
