Will 2 GTX 580's be bottlenecked by my CPU? - Page 8

post #71 of 77
"Bottleneck"

That term should be outlawed.

Outside of a handful of games and most synthetics, you will never notice the difference between a 4ghz Wolfie, 4ghz i7, or a 4ghz SB.

I take that back, I don't there is a single game out today where you would notice a "bottleneck" running sli 580.

How about I say, you know what your SB at 5ghz is bottlenecking your set up.
I'd be right, you know why...
Because I'm pretty darn sure an SB at 6ghz is going to give better frames in Vantage or 11 than an SB at 5ghz.
But it's a stupid thing to say, huh?

What if a Q9550 at 4.0ghz?? will it bottleneck the 580sli?

It's not a stupid thing to say if it's true (which I doubt it would be on 11, but would be in Vantage Performance Mode).

Look, bottlenecking is a very simple concept ... something acts a bottleneck when it acts as a limiting factor to performance of the system as a whole. Like, ANY amount > 0, at all, in any way, etc (this assumes you properly account for margin of error, of course )

There's lots of scenarios where CPU's don't act as bottlenecks. Take for example, the process of moving data from one HD to another ... it doesn't matter if you run a single core Pentium 4 or a 980x at 5GHz ... moving stuff from one drive to another, the CPU will never be a bottleneck. Likewise, there's no GPU setup you can have where an i7 at 4.0 will bottleneck you in 3dMark11 Extreme mode ... at least not in terms of your GPU score.

Fact is, there are some on OCN who prefer to discuss the BN concept in literal, precise terms (like myself), and some who prefer to make up their own terms, like 'there's no bottleneck unless you NOTICE it, with the naked eye'. Which is fine, I suppose ... you can call the ACTUAL definition 'stupid' if you want, you can think that ... but ... from a standpoint of actual accuracy ... you're wrong, and your definition of the term is wrong.

There are literally TONS of GAMES where, depending on settings, and what gfx solution you're pairing it with, a Wolfie at 4.0 won't perform anywhere near an i7 at 4.0.

And it's irrelevant whether you can 'notice' the difference w/the naked eye, because the proper definition of a bottleneck doesn't involve what you can 'notice', it involves what you can MEASURE.

You can decide you don't CARE about a bottleneck, say it's insignificant, or whatever, that's fine.

But the word has a definition, my friend. And personally, I stick with those when I discuss things on this forum

It's clear to me that you're one of those people constitutionally incapable of admitting that you've mispoken, let alone able to admit you're flat-out wrong.

Welcome to my ignore list, sir

Yes they will be bottlenecked but you shouldn't care because they're still going to perform very well.

The most you can do with current CPUs is reduce the bottleneck. (Hence a 4.2ghz 980x getting a higher score than a 4.0ghz 980x...so on so forth)

At the current rate of advancement, next gen CPUs will also be the same with next gen GPUs

Therefore, it's foolish to ask "will this bottleneck?" since the answer will always be "yes".
The smarter question would be "will this provide a smooth experience?"
