Ultimate Bottlenecking Guide/Discussion Thread!

[Sagittariusss]

Wait, how's the i5 4690K is worst than the I5-6400? doesnt makes any sense at all. Quick google research on reviews and figured out the i5 4690k is better in cpu-intensive games.

Simple, core clock. Haswell's performance compared to Skylake isn't that significant at all. Plus, add in the 6400s really low core clock compared to a 4690k at a high overclock, and the 4690k will always win.

if the i5-6400 was overclockable could we overclock it that much? maybe, but we can overclock the i5 4690k aswell. Basically you said, the i5 4690k is better than the i5-6400, and i still dont know why in your chart it is worst.

#edit thought you post was about bottlenecking and not about power effiency per fps.

Which specific chart are u talking about? Cause that's a typo of I said the 4690k is worse than the 6400.

The 6400 is actually overclockable, but you have to use BCLK which won't get you far at all. I can imagine you'd top out at 3.2ghzish.

So how the i5 4690k would bottleneck more if at any application the i5 6400 is worst than it? I'm talking about this chart http://

I have a Xeon processor, which is not listed in this list. Can I think it as an i7 processor with its hyper threading?
Will a Xeon 1230v3@3.3 Ghz (Haswell/Ivy Bridge-E, Intel 4th Generation) bottleneck a MSI GTX 1070 8gb Gaming X?

I see your point. Let me fix that.

Your Xeon is the equivalent of a i7 4770/4790. So you shouldn't get any. If at all, you'll only be in the pink.

TechyInAZ, thank you. Got my MSI GTX 1070 today (upgrading from MSI GTX 970) and I did benchmark previous card and my new one. Seems to work good, although on FireStrike I don't get too high results. On the other side 1) system fans and whole system setup is set to slow and quite operation, 2) I don't overclock cpu and gpu, 3) compared to benchmark sites, they have usually newest cpu and ram overclocked. If anyone want to upgrade to same graphics card on a Xeon processor, I can fully recommend it here now.

P55UDR3 gigabyte (motherboard)
Psu 500w
Intel i5 661 @3.33ghz
Wanting to upgrade to 1000or 900series
Will it bottleneck my pc

Your CPU is going to bottleneck any GTX 900 series or 1000 series GPU unfortunately.

When you going add Ryzen 7 on there

:lol: Ryzen 7 just launched, nobody even has "real" benchmarks on it yet. Can't make a graph until reviews come out.

But when they do come out, i'll definitely make a new spreadsheet.

 

[valeman2012]

It be funny if AMD going drop bomb on us again, just like the FX 9590.

 

[TechyInAZ]

Just letting you all know that I updated the Bottlenecking Guide with a VERY VERY critical variable I actually only learned a month ago, that is bottlenecking based on frame rate.

 

[Jonathan Cave]

any chance of a 1080 ti update good sir?

 

[TechyInAZ]

Yes. There will be a new chart for 1080 TI. However, just like for Ryzen, I need to wait until many people get their hands on these cards, so I can at least get a semi-accurate chart up and running from the get go.

will a i7-4790k be alright with 1 RX 480? or should it need 2?

1 or 2 will be fine. The 4790K won't bottleneck them either way.

I'm looking at a 2nd gen i7 2600. Don't know if it's 'K' and a RX 480 nitro+ to replace for a client. I don't see it listed. The other is my i7 3770K and a RX480. Think I'll encounter a 'bottleneck'?
Thanks.

Maybe a little on the 2600, but doubtful on a 3770k.

Calling ALL GTX 1080 Ti owners!!

For those of you who have a 1080 Ti, it would mean a lot to me if you guys could give me your estimates on how much you would consider your systems are being bottlenecked by the 1080 TI, if at all. Basically, I consider 90% GPU usage or lower to be a legitimate CPU bottleneck. 90% is pink. 75% is blue, 60% is red. These are all AVERAGE GPU usages.

Unfortunately, I can't just call up Nvidia and tell them to send me a 1080 Ti for me to use. So I need users like you guys to help out.

Thanks bro. It's surprising how fast time ages technology goodies. I feel I just built my 3770k. Next month will be 4 years.

Congrats! I'm going on 3 years with my 4690K. Has been a real champ! No bottlenecking issues on a 1060 at all.

Built a 1700x/1080ti for a friend. Really never hit much of a GPU bottlneck, but he wanted a 1440p/120hz setup. It skirted in the 80-85% usage a time or two but the those situations the fps was always in the 180+ range and CPU usage was nearby so it'd be tough to call it a bottleneck at all

Your probably hitting a bottleneck, but it's so minor that it really doesn't matter. Once you hit 180fps, bottlenecking isn't important.

Whoever is trying to gain editing access to my spreadsheets, please, list the changes here and me or another moderator will add them to the chart.

I'm not seeing any issues with a 5930k and 1080 Ti. Afterburner reports 99% gpu usage.

My TITAN Xp arrived today and I did a few tests to see if my old CPU is holding me back.
My current configuration is:
i7 4790K @ 4GHz
16GB RAM Corsair Dominator @ 1600
ASUS MAXIMUS VII HERO
Apart from the TITAN Xp, I also have ASUS 980Ti Strix set to do PhysX.

With my old setup (980Ti + 970) I did the test only on Rise of the Tomb Raider and the GPU usage was at firm 100%.
All the games below are on maximum graphics settings @ 3440 x 1440 and they run perfectly (I had no way to see the exact frame rate tho').

Rise of the Tomb Raider

It seems to stay well into the 99%. The initial lower usage is while I was in the game menu.

NieR Automata

Much lower usage here. This is the beginning of the game, where you have plenty of 2D-ish sections and not very intense combat. But it seems to be staying mostly in the 70 - 80% range.

The Witcher 3

Lind of up and down here, jumping between 80 and 99%.

The last one is Iray Rendering in Daz Studio

Here both cards are staying pretty much firmly at 99%. But I don't know how indicative this is, since the CPU is excluded from the rendering process.

What do you guys think? Are my other components blocking the GPU, or it just doesn't need it's full power 100% of the time?

 

[Hunter21]

Hi there, I'm running a 1800x+1080 ti setup. GPU usage differs depending on the games I play, I was getting pretty steady 97-99% on titles like battlefield 1, witcher 3, battlefield 4 (1080p). Far cry 4 however hates the setup, the gpu runs at 40-50% on 1080p and doesn't get much better on 1440p, even at 4k it does not stay at 99% most of the times (frames difference between 1080p to 4k is literally less than 20 frames). For crysis 3 it sometimes hopes to 60s and 70s but most of the time it stays around 99%. Hope some of my information helps, really wish they start optimizing ryzen now so I don't make myself look dumb going from a 4790k to a 1800x 🙁

 

[TechyInAZ]

Thanks a ton guys! This is exactly what I need.

Expect a whole new set of bottlenecking guides for Ryzen and 1080 Ti soon.
