CPU Core Scaling For Gaming | Benchmarking Resolution & CPU Cores - Starting At Just ONE Thread!

In this analysis, we'll be testing out the effects of the number of processor cores vs different gpus and resolutions. WE're testing with both Nvidia's GeForce GTX 1080 Ti and GTX 1080, with resolutions of 1080p, 1440p and finally 4k.

During these tests, we'll use different processor configurations to see the number of cpu cores to see bottlenecks for gaming at different resolutions.

Testing from just a single processor core all the way up to the I7-8700's 12 threads, on both the gtx 1080 and gtx 1080 ti. What games are playable and where is the sweet spot in price and performance with these higher performance gpus, and what's the best CPU configuration for you cash for gaming in 2018?

"Four cores eight Freds, and Hyper-Freds"

"Pushing the amount of Fred's required"

I've been taking a swig of wine at every instance of "fred". Only at 3:50 and too drunk to continue.

some more great original work paul! love to see it

Just commenting because of your nice request, keep up the good work.

3:43 Why does the GTX 1080 out score the GTX 1080 Ti in the Ashes tests?? That should never be the case, regardless of how many CPU cores are active when compared to the GTX 1080 with the same Cores/Threads active.

[Lazarosaliths]

happy to see that my 6600k still kicks as in an age of over killed high core count cpus! with the next generation of ryzen, 8c/16t will be the norm for most users !!! lets hope games change so they get advantage of these cores!

[ndLastJedi]

What happened to the 4c/8t on 1080ti here 3:39 ? Compared to 1080 ! Graph wrong ?

[grumpyoldman]

RedGamingTech - when you say "manipulating active core count" do you mean using windows affinity or are you setting this in the BIOS or other software for whole system not just game? because I find when I limit my games to 4C/8T and leave 2C/4T for the main system (I7-8700), its always more smooth for me... P.S. for those wondering what I mean, bring up task manager, go to "details" then right-click on a program and scroll to "set affinity" and select which cores/threads it will be allowed to use, by leaving a couple the game can't access it helps the underlying system work through all the background junk you have going... you can monitor core/thread usage in the "performance" tab by right-clicking on the graph and changing it to "logical processors"...

Steve at Hardware Unboxed actually did a suite of gaming benchmarks at the usual resolutions, 4K, 2K, 1080p with a 1080Ti and at 1080p there is a 1-5fps difference between an i7 8700K and an i7 2600k I play Oldrim (Skyrim Legendary Edition) a DX9 game at 1080p with a Ti and the difference between an i5 ivy (4 core) and an i7 sandy (4 core HT) is 50% in game. I still get 4fps in places, but that's an engine limitation :) YOu do not need modern hard for decent gaming performance my R9 390 would run Witcher 3 at 60fps @1080p all day long. The Ti laughs at it, even with hairworks on.

Hitman Marrakesh level for example should be quite hard for 4 core 4 thread cpu and i personally prefer hardware that can handle any task perfectly.

[balbinderful]

That's some odd results: I tried that with my Ryzen 2700X in Far Cry 5 - 8 core downs to 6 cores and lost 2.72% in FPS. So, you're essentially saying core scaling is inferior on Intel CPUs. Nice to know!

[Phredreeke]

for games where hyperthreading causes reduced performance, can you get around the performance hit while still having hyperthreading enabled by launching the game with the start /affinity option to only use the odd or even logical cores?

[ndLastJedi]

What about VR Sim racing like Assetto Corsa, Project CARS 2 ?

[soylentgreenb]

My prediction is that you will rediscover Amdahl's law, toghether with some games relying on x numbers of cores (probably mostly 2 threads) to avoid grotesque stuttering.

[johandodenedgren]

Got a 4770k and it's more than fine with the ti @3440x1440.

[JTKGAMING]

I think U ment to say it will be gpu bound at higher resolutions not CPU bound

[andrewfong]

Anyone know if there would be bottlenecks with my i7-7700k on a z270 mobo when I upgrade my GPU to the new GTX 1180 coming out end of August?

[grnbits]

Is that only on Intel? i think on the AMD side this doesn't happen.

[VFDB]

I upgraded last year to a 3770k from a 3570k, it only cost me £50 once I sold my old cpu.

[TheSilviux]

Same old limits... It's the Windows that limits the performance, not only for 6 cores, but the utilization is not the same fot all the cores.
The single core is important, after that, the first three are most useful, the other three are utilized less and less..
That was a slide for dx12, back before it was available!
