Hi all,

I'm hesitating to sell my i5-8600k and get the i9. its certainly not cheap (500euro) and i'm seeing mixed results from benchmarks i see online.

Currently i have the i5-8600k running @5ghz and i would do the same with the i9.
I know many games would see much of a performance jump and yet several ones where it might.
i'm also thinking future wise, i don't think we will see any new intel cpu's on the socket 1151 so i9 is the big boy on the block, but is it worth it? and i might want to save up and get a 2080ti after a few month's instead.
ideal would be that i can test the cpu for a week ofcourse :D
has anyone done the upgrade? or what are your thoughts?


i5-8600k @5ghz
3600mhz RAM
M.2 evo 960
1080TI
 
Also agree and for pure gaming there is a tiny difference between the 9700k and 9900k.

It’s also worth researching your motherboard with the 9900k. While all Z370 & Z390 boards technically support it you need a board with high end VRM’s to run it properly. It also needs a high end cooler.

I have a maximus x code motherboard and nzxt x62 kraken cooling, on that side i'm good, the onyl true upgrade for my 1080ti is a 2080ti and that's 1300euro.. in games like assassins creed odyssey an overclocked i9 would give a significant bump in fps to the i5-8600k but bu how much exactly i don't know. but i guess its best to wait more.
 
What resolution are you gaming at? Below is a review from techpowerup and it shows the performance of both the 9900k and the 8600k. At 4k in ACO there was less than .5 fps difference between the CPUs. At 1440p there was less than 1 fps difference between the two CPUs.

Even on the average of the games tested, there was less than a 1% difference in fps between the 8600k and the 9900k at 1440p and 4k. When you move up in resolution the bottleneck moves from the CPU to the GPU.

In the test below were conducted with a 2080ti, so the comparisons will be very similar to what you would see.

If you are not gaming at 4k or 1440p, there is not reason to spend 1300 on a 2080ti as the 1080ti will get very good framerates at 1080p.

Whether an upgrade is worth it or not, the i9-9900k is a complete waste of money.

In the US it exceeds the price of the i7-9700k by about $130, or, in Germany, about €110 more.

They both have the same 3.6GHz base clock. Boost clocks are only 100MHz higher for the i9.

You would be spending a lot of extra money for bragging rights, with no noticeable performance gain.

I game at 1440p 144hz, but you make a good point of bottleneck going to the gpu. also great thread you've posted i hadn't seen that one, that puts me off from buying the i9 :)

There is more of a difference that that base clock. the i7 is 8core 8 threads the i9 8 core 16threads. and as i mentioned i would overclock to 5ghz so base clock doesn't have an impact in my case but number of cores and threads does. my i5-8600k 6core 6 thread

Another poster also mentioned this, but the extra threads don't help in gaming - as games aren't using that many threads at this point.

Even the 6 threads of the 8600k are good. Now, if you're planning on streaming while gaming, or doing other things that specifically benefit from more cores/threads, then that's a different story.
