wanting to upgrade cpu from I5 8600k to I7 9700k

[Kumoko]

i think im begining to hit a wall on my cpu usage i run a 1080p with rtx 2070S with multi monitor played battlefront and cyberpunk 2077 and both games seems to be hitting 100% for most part but the 9th gen dsent have hyperthreading :/ no more 8th gen being sold at my retail store 2 do i need the hyper threading for my setup?

What motherboard do you have? What's your budget? Is a Core i9 9900K an option? It's ~$100 more and it does have Hyper-threading, so it'd be a bit bigger of a jump.

The 8700K (6/12) and 9700K (8/8) are increases over what you have, but rather small ones. IMO it's worth the extra $100 to get a decent increase rather than the smallest one over what you're already sitting on.

my mobo only 1151 i could potentially get an I9 9900k but i want to get a ps5 as my ps4 is acting up soo that leaves me with either getting that 9th gen I7 or buy a used I7 8th gen since retail dont sell that anymore on my side the i7 9th gen dsent have hyperthreading which might b usefull as i run stuff on the background while playing?

[_I_]

not much of an upgrade

core performance is identical when either are oc'd

the i7 has 2 more cores, both have ht
(all 8th gen i series and later cpus have ht enabled, only ones that do not are the celeron lineup, pentium is dual core with ht)

for most games you will not notice any difference

my cpu is hitting at 100% though during playing triple A games so an I7 may help not hitting 100% pretty sure thats called bottleneck

make sure msconfig shows 6 cores enabled (or untick if it was limited to fewer)

A number of 9th generation CPUs don't have Hyper-threading, such as the Core i7 9700/K. The Core i9 9900K is essentially a Core i7 9700K with Hyper-threading (plus maybe clock speed differences, but the aforementioned difference is the big one).

[nullable]

The 8600k doesn't have hyper threading, that's the biggest difference between the 8700k and 8600k. 6c/6t 8600k, 6c/12t 8700k. Neither does the 9700k it has 8c/8t, the 9900k has 8c/16t.

I would agree it's not a huge upgrade for say gaming (would be game dependent). But having 30% more processing power would have benefits in applications that could utilize it. So how large the upgrade is is a matter of workload.

i5's tend to always report 100% usage. I would look at gpu usage to see if there is scope for an fps increase.

u cant really bring out full potential of the gpu if ur cpu is holding it back from doing its best as mentioned the cpu is doing more work while playing games which should b the other way around i tried lowering settings etc still the same

I'll write it another way.

You need to determine if the cpu is holding back the gpu because the 100% cpu load score is unreliable.

Fps is determined the gpu. The higher the load % the higher the fps.
If the gpu is at 100% load, nothing will produce more fps (except sometimes turning down cpu settings).

To produce a higher gpu load, the cpu threads have to run faster.
In other words increase the single thread speed.
Overclocking increases the single thread speed.

Example - overclocked 8600k versus stock 8700k. The 8600k produces more load on the gpu.

And again, higher thread speed wins (and faster memory) -

Why is the 100% usage for i5's is not necessarily correct? Because the score is produced by the benchmark software not the cpu. The software takes a sample maybe once a second. But taking the sample uses the cpu. And asking the cpu thread for the load may cause the thread to go to 100% load.

That's why you use the gpu % score for i5's if the cpu is showing 100%.

(It's highly unlikely that a cpu can simultaneously run at 100% all the time on all threads if it's doing a lot of i/o.)

So do you need a 9700k? If the gpu load is currently less than 100%, for example 80%.

It's a good upgrade anyway.

cpu is at 100% most of the time gets around 90-95% when no barely npc cars roaming around. its gpu load is at 50% / 60% again with barely no npc or cars. i wouldve ask if my pc is being bottleneck if i didnt know but obv if the gpu is not using 100% or close to that then i would assume its the cpu holding it back esp on a 2020 game

[A&A]

There is no need to update with one more gen because Cyberpunk 2077 is the heaviest game in the moment it is eating a lot CPU power and GPU power
So don t worry my friends have same issues
