i5 8600K vs i7 8700K for 3D Vision?
  1 / 4    
Is there a performance difference betwen i5 8600K vs i7 8700K for 3D vision/NVIDIA Surround/VR/dolphin emulator, assuming they are overclocked to the same clock speed? If one was to pick a chip for 3D Vision/VR/Dolphin Emulator, would the i5-8600K be a better value/performance chip? Thanks

I don't think that as of today, the extra HT cores make a noticeable difference in games. I know some utilities like Handbrake and WinRAR will benefit of HT but for games I have doubts. Current 3D Vision are not HT optimized, no idea about VR and emulators. I won't say 8700K is far superior. What about AMD? I have no idea though... I went Intel again this time.

3D Vision must live! NVIDIA, don't let us down!

I'd assume the emulator is where it's most likely to make a difference. if dolphin is a sizeable enough percentage of your gaming, I'd say it'll be worth it to have HT, otherwise perhaps not.

That i5-8600K is an interesting spot, because it's a six core, no hyperthread setup. I've yet to run across a game that uses more than 4 threads, so that would likely be a good value spot for at least a year or two. You won't likely be able to overclock it as well. The way chip binning usually works is that they try to make as many of the high end parts that they can, shooting for best i7-8700K. Then defects in manufacturing show up, and the parts that are rejected wind up in lower tiers. So for example, an i5 is an i7 part that failed the hyperthread testing in at least one core, so they turn it off altogether, and sell it as an i5. Same thing is true for lower tiers, like i3, and even the laptop type parts with lower clock speeds. They down-bin the parts to wherever they can pass their tests and sell them there. It's all the same design, not different designs for each type. That means that the parts you get for something like an i5 already failed some test, and thus will not be the best of the crop. But as far as being a good value, I think a 6 thread chip today would be a good value proposition. For Surround, I'm less sure because I've not run it, but in general you are capped by GPU performance in Surround, so the CPU should matter less. For VR, it definitely will not matter, the vast majority of the VR software is single threaded. The two big game engines of Unreal and Unity do not effectively use multiple cores. I don't know anything about Dolphin, and will defer to others.

i thought ppl turned off Hyperthreading when they OC their 8700K so the hyperthreading feature on i7 8700/8086K is a moot point? So does hyperthreading help with 3D Vision? p.s. I am confused when it comes to hyperthreading vs. "regular thread". Apparently 8600K has 6 threads, no hperthread vs 8700k 12 threads with hyperthread. Can someone comment on how relevant these are when it comes to 3D vision, if at all?

@J-Enermax If for 3D Vision I would have to say no it doesn't matter.

zig11727, that vid is comparing a heavily OC'd 5GHz i5 on all cores to a stock i7 at 3.7 base, sometimes turboing a single core to 4.7. It's not at all a fair comparison.

Umm... huh? :( This is not how you benchmark mate, or perform any kind of experiment. Please see my other thread for proper benchmarks from a reputable source :)

@RAGEdemon, Even if the stock I7-8700K is turboing on one core the difference is due to hyper threading I5 is running 5 GHZ on all the cores it very fair comparison because I5 single core is running faster then the I7 turbo 4.7 and the main difference is hyper threading. Also CPU usage is half and temperatures are a lot lower when hyper threading is enabled.

When hyper threading is disabled your CPU usage and temperatures will almost double. I7-8XXX and I5-8XXX run very hot stock.
