Bottleneck

[Blaze2k]

Searched the internet about bottleneck and found a site that calculate the bottleneck percentage put my current pc fx 8320 and msi gtx 1060 gaming x 6gb with sata 7200rpm and showed 7% bottleneck,put the pc i want to build i7 7700k msi gtx 1060 gaming x 6gb with ssd m2 and showed 13% help?

[owencrispy]

this happends because the 8320 is bottlenecking the 1060, however if you build the other pc the 1060 is actually bottlenecking the 7700k

It sounds like a shitty site, ignore it. 

 

A 7700k won't bottleneck a 1060, a 7700k can handle a 1080Ti no problem.

[Princess Luna]

To begin with any website that calculates bottlenecks feels like a scam to me, secondly there is no bottleneck at all on a i7 7700k + GTX 1060 as the i7 7700k can squeeze all of the GTX 1060 potential with ease.

well....it won't.

I run my 1080 Ti with a i5 3550 w/o any problems

i'm not sure how a processor can bottleneck the same processor

gpu dont bottleneck cpu right?

[RAM555789]

What they mean when they say the 1060 will bottleneck the i7 7700k is that it the GPU will not be able to push out enough fps to make the CPU struggle at all. You can't however say for certain what your bottlenecks will be due to overclocking, the quality of your parts, how cool they are kept, ect.

[owencrispy]

so i was right in saying that the 1060 does bottleneck the 7700k?

thinking of overclocking the cpu at 4.8 with nzxt kraken x61 or x62

I see this question way too much.

 

There is no such this as a F'ing bottleneck.

 

If you drop a pentium into a cpu benchmark with a modern graphics card then it will slow down performance in a multicore optimised environment (mainly open woreld games and transcoding)

 

Drop the same cpu in LoL and it won't give a F.

 

Figure out what you're doing and then figure out what specs you need to accomplish them.

At least 1080p max settings in the upcoming games

1080p... anything after 900 series. and most of the 700 series (80 and Ti) resolution requires a decent cache to be able to store frames. 970 ran into this problem when required to work above 1080p. it wasn't a processing problem it was just shear amounts of storage required.anything more than a 4GB and up will run a flawless 1080p experience.

RX 580. If you wanna go a little overkill, get a 1070, as it'll be more future-proof.

[RAM555789]

Anything from a 4gb 470 to a RX 580 8gb will be fine. Just make sure you have a CPU that can keep up with the frames.

What I wonder is how the hell they come up with those numbers. If they don't say anything, then you may as well say "I fart pixie dust."

What site did you find? I'd be interested to see exactly how they calculate this, then we can prove/disprove their calculations. 

 

TL;DR - don't mistake the word 'bottleneck' to mean that it will effect system performance in a tangible way. 

 

In general:

 

1. Any CPU/motherboard configuration which forces PCI-e multiplexing could be considered a bottleneck, but would only cause a few frames-per-second loss if the GPU(s) was(were) fast enough to demand that bandwidth from the CPU, and the storage was fast enough to supply the information to the RAM, assuming the game hadn't already pre-cached that data in RAM at a load screen, which also assumes you had enough RAM and it was fast enough.... this is the nature of any system. The 7700K shows 16 PCI-E lanes. Your M.2 SSD likely uses a PCI-E lane to communicate with the CPU, which means if the motherboard's PLX chip is enabled, it handles the traffic between the GPU and the M.2 (as well as the sound card, network card and any other integrated component which also uses PCI-E lanes). If you were to disable the PLX chip, assuming your motherboard will allow you to, you would create an even greater bottleneck, but you would prove the point that people who run higher-end CPUs make, such as the i7-6950X, who have a dedicated 40 PCI-E lanes which do not require multiplexing. This is a common source of contention of the internet because the technology is misunderstood, motherboard marketing isn't entirely accurate, and the bottleneck is rarely noticeable enough for it to matter to those of us who don't spend >$1K on a CPU.

 

2. Any delay in storage reading and writing could cause longer load times. A single mechanical drive is almost always slower than a decent SSD.

 

3. Processes or management software running in the background could reduce CPU response time. So, likely, will malware. 

 

I spent countless hours researching these technologies between when I bought the parts for my build and when I re-bought the parts for my build (due, in order, to RAMgate, smoke, low FPS in Wolfenstein, and overheating). You can find my posts in the ASUS, EVGA and Hard OCP forums when I was uncovering issues with the PLX configuration recommendations in my mobo's manual, flashing mono BIOS several times, flashing GPU BIOSs, and figuring out how G-Sync behaved in certain games. I spent far too much money for what I have, so I can appreciate the fear that comes from doing just that. I think it's what drives us to pick over the potential pitfalls of a build.

 

If you've read the reasons above, I can guarantee you that your build will suffer from a bottleneck. The thing is, you'll likely never be able to tell.

In the LGA 115x series boards, in general, the 16 lanes of PCIe in the CPU is solely dedicated to the x16 slots. Everything else is handled by the chipset. In this case, M.2 talks to the chipset, the chipset talks to the CPU via a dedicated interface. Even if you plugged in the NVME SSD into a x16 slot, the CPU would assign only 8 lanes to the GPU with the remaining lanes up for grabs. In the X99 platform though, the M.2 slot generally does connect to the CPU's lanes, but they are dedicated.

 

tl;dr, there's no multiplexing going on. Multiplexing with a PLX chip only really happens on high-end LGA 115x boards that offer multi GPU configurations beyond two cards.

ect.

ye right

I'm not trying to be difficult, just looking for clarity here. Note that this discussion doesn't detract from the fact that bottlenecks exist regardless of configuration.

 

The OP did not list a motherboard, however he did list a 7700K, Which Intel's Ark says has 16 physical lanes which can be run at 1x16, 2x8, or 1x8 and 2x4. This limitation cannot be overcome in any other way. Unless you disable all the PCIe-based features on the motherboard, you will not get more than 16 lanes to the GPU. But this is academic because a single GPU likely won't use all 16 lanes. I think we're saying the same thing here.

 

The motherboard manufacturer chooses how to configure their PCIe slots. In my case, the manufacturer chose to wire the first slot to the CPU and every other slot through a PLX, even though it's a Z97 board, causing a performance hit when I ran SLI between slots 1 and 3, whereas putting the cards in slots 2 and 4 provided a better result as load was increased and communication between the CPU and cards increased. Note that I had to speak with the EVGA engineers directly about this as the manual was actually incorrect. This would indicate that a board does not have to be X99 to have PLX, but that's outside of the scope of the OP's question anyway. 

 

I will concede that the DMI handles communicating with the chipset, so most of the built-in components communicate with the CPU through that. I still think the motherboard manufacturer can specify wiring here, but I'll ask a few and do some research until it makes sense to me.

 

For reference to @M.Yurizaki and my points, check the diagrams attached.

-Snip.-

The overall point though is that M.2 does not route to the CPU's PCIe lanes, unless it's plugged into an x16 slot (which generally means it's using the CPU's lanes) or is an X99 motherboard. The most that using an NVMe M.2 SSD does is disable a SATA port or two.

 

And I rambled on elsewhere.
