m8 there is no bottle neck with me rtx 3090, ryzen 9 5950x 8gb 2166mhz pc it preforms amazing! I really love my 2tb 5400rpm windows xp drive. It preforms like a champ.

You mean you don't have a 120GB boot hdd?

BRUH... you seriously went Ryzen 9 over Sempron??? WTF man.

Nah i got the 2tb drive on ebay. IT WAS AN AMAZING DEAL!!! It has a clicking noise i like to use as a metronome when I play music. It even has this amazing feature where it freezes everytime it detects malware! I got it from this new seller that I felt bad for as he said he had many of these that he needed to get rid of fast.

"Do you need to upgrade your CPU or GPU, well the answer is it depends" 

Your CPU of course, because there is no such thing as an affordable GPU upgrade right now. 

 

I suppose the ultimate question comes down to this:

 

Bang for buck improvements...

Faster RAM

More RAM

Faster CPU

Faster GPU

Faster Storage

 

Which one is money better spent?

Well...to steal a line from the video, "it depends."

I mean honestly who even goes AM-Fail anyway? That's just nothing but moar core fallacy logic! Intel single core is all you need!

Nickelback Linus is a sight I can never unsee.

IKR! So true. My Pentium 4 + 3090s in SLI run great.

[Murasaki]

No it doesn't!

Bottlenecks in computing systems are a fairly nuanced topic.

 

In a typical "gaming" PC, we are though mostly concerned about CPU and GPU performance, and memory bandwidth comes in as a close second, followed quickly by storage bandwidth/latency and overall network latency if one plays online. Though, to be fair here, there is a lot of stuff happening in the background that effects performance by a lot that is outside of the scope of the hardware itself.

 

One of the bigger things to consider for parallel workloads is Inter Process Communication _{(IPC, not to be confused with Instruction Per Clock that also is IPC...)}, since communication between our different nodes in our system tends to be a major limit in regards to how well we can scale our parallel workloads across multiple resources. In short, inter process communication is a large part of how well we can scale in accordance to Amdalh's law. _{(Our IPC practically allows us to scale down towards smaller parallel workloads as inter node latency decreases, as long as we have sufficient bandwidth to handle our workload. And funnily enough, the other IPC that is our out of order execution works its way up from our smallest parallel code segments towards larger ones. And idealistically these two could meet in the middle to reach perfect scaling in accordance to Amdalh's law. But there is practical limits to how easily one can implement such.)}

 

Then there is also a question of how various process calls are made, what queuing system the OS/Kernel uses, and how many IPC related background tasks one can keep around in core resources. Leaving an IPC related thread in a core despite it stalling the majority of the time is actually something that can improve overall system performance fairly noticeably through an increase in responsiveness, all though mostly applicable to more HPC related applications, or other situations where tight IPC is required, like large NVMe based storage servers. It is similar to the difference between a buffered and an unbuffered switch. _{(Here CPU vendors could just implement a higher degree of SMT, as to keep more IPC related threads in our cores while not having to worry about missing out on performance due to them stalling.)}

 

This is though just me talking straight from the top of my head, there is potential that one might see this as gibberish...

I wonder if my RTX 2060 is being bottlenecked by the Ryzen 5 2600 I'm running ಠ_ಠ 

[Jean-Nicholas]

This is the kind of video that 5 years ago me would have appreciated a lot more when looking at build guydes, or CPU reviews than I do today. It's a good subject matter that is worth talking about every few years I think.

[-Overkill-]

Well, my current pc has an AMD RX 570 4GB, Ryzen 5 3600G, and 8gb (soon to be 16gb) of ram. Would upgrading to a RTX 3060 bottleneck my cpu or anything?

I doubt it. But that depends on your workload, of course.

You'd probably have more performance uplift by upgrading your CPU than your GPU as the RX 570 is still a pretty good card, compared to an APU.

That being said, it's my perception that APUs are slower and less performant than a full fledge CPU, but don't let that stop you from wanting to buy a piece of silicon paper.

 

As I said above, it depends on your workload.

Its been fine for every game expect GTA V, RDR2, CP2077 and AC: Odyssey.  

  

Cyberpunk is the worst of the bunch, no matter the settings everytime I move to mouse it drops to <40 FPS

GTA V is mostly fine but I had to try a lot of settings before settling on something does that 75 FPS on avg but it still drops to 50's.  

RDR2 almost runs perfect but has one of the ugliest stutters ever in crowded areas.  

AC: Odyssey is also never great, I raise the settings GPU usage goes up FPS goes down, I the lower settings GPU usage goes down along the framerate

Would have been nice to include 'old' CPUs in the benchmark rather than lower end models of recent CPUs.

 

Reason being, its far more likely a person to have an older platform, than a newer one running a lower end part.

 

Example.. ME

Rocking a Oc'd Sandybridge 3930k with a 1080ti.

Now i know im seeing bottlenecks in certain situations, but not in every situation.

For example in the last few days i've decided to play some No Mans Sky again.

At 1080p with 170% resolution scaling, and max settings (minus the god awful AA), im maxing out my GPU and 'only' getting between 50 and 70 FPS on average due to how Un-optimised the game is. In this situation i'd benefit from a 3090 more than a new CPU.

On the flip side, if i play a game like say, Monster Hunter Online (kinda bad example its also not well optimized but does lean on the CPU somewhat), or Doom (though i dont actually have it), i'd see a good chunk of performance from upgrading to a newer CPU specifically at 1080p.

 

However, since my next major upgrade is going to be to a 4k OLED, and ill need HDMI 2.1 for 4k 120hz, ill need a new GPU. At that resolution and frame rate, my CPU isnt likely to be causing much issue.

 

So yea, i think it would have been more helpful to use a selection of popular older CPUs rather than all more recent ones, but include at least 1 lower end more recent one for reference.

maybe:

2600k 4c/8t

4770k 4c/8t

6700k 4c/8t

8100 4c/4t

9900k 8c/16t

I have a i5 3570 for the cpu, rx 580 for gup, 8gb ddr3 ram and a 650watt psu. Im looking to upgrade to a ryzen 7 16gb ddr 4 ram with a b450 motherbard. Im not sure for the gpu yet.

[Quackers101]

maybe a some good in the video for newer people, else there was a lot of cringe in it.

[Streetguru]

Why didn't ya simply mention that.

CPUs cap your max fps

GPUs cap your resolution/quality settings

and game engines naturally bottleneck too.

Should have ran CS:GO with a 3090 at 480p 50% resolution scale just for fun though too.

[SietseB]

But how do i find my bottleneck before buying a bunch of GPU's or CPU's?

 

I have a Ryzen 7 2700 and a GTX 1080 Ti (Gigabyte gaming OC)

 

Not that I'm going to upgrade in these times but maybe down the line.

the 1080ti being in the range of the 2080. ti?

Not having the same features as the RTX series, but very powerful. 2700 is a bit older, and weaker in single core for gaming. still decent hardware, although newer gen features are lacking like ray tracing etc.

[dogwitch]

well am good on this issue with ether main build i have.

[MultiGamerClub]

impossible, my 1700 runs fine!

The only bottleneck in my gaming rig is the nearly-50-year-old playing the games on it.
