Wrong.

Ignorant.

My CPU @4.0ghz has no problem driving 4 GPUs upto 98% efficiency in BF3 are you telling me if I was to change to a faster CPU like an overclocked i5 I could get equal/better performance in BF3.

No it will not, it will be about the same. If you clock you CPU down to 3GHz, there wont be a difference. Unless you going to run a game in 800x600......

ignorant.

Don't see any multi card comparisons in 64 MP on your link. Who's ignorant?

No-one is debating an i7 doesn't help for single card set up's so I'm not entirely sure why you've re-posted a single card/single player link.

Please could you also explain this then?

I upgraded from an i5 2500K/680 SLI combo to an i7 3770K/680 SLI combo. Same Windows install, same drivers... old CPU out, new CPU in... overclock applied.

And the plethora of users on the forum who have done something similar and noticed the same.

I do find it amusing that you're saying Kaapstad doesn't have a clue about his hardware and yet you're arguing in the face of evidence to the contrary without any actual evidence (of what we're debating) of your own.

An overclocked i5 can not drive 2 GPUs @98% in BF3 at any sensable oc. Trying to drive 4 GPUs it would have no chance.

I notice you like posting a lot of links to things that are only semi relivant, do you have any first hand practicle experience about the subject.

 

[Gregster]

Another desperate sole not willing to admit he is wrong. I also went from an I5 to an I7 3930K and the improvement in BF3 is huge. I didn't bother to reinstall windows or anything. Stop giving bad information Devion please and sometimes we think we are correct bad sadly we are not.

 

[Devion]

Multicard wont change a lot. If an Athlon x4 630 and Core i7 3960X have the same performance on 2560x1600(Hell even on 1920x1200), how there going to be a difference CPU which are 10% apart from each other in a dual GPU setting?

http://www.guru3d.com/articles_pages/radeon_hd_7970_cpu_scaling_performance_review,3.html

But you want multi GPU? Well lets even go further then your normal SLi setup, lets try TriSLi (And lets be clear, my argument was about TS system, now Im taking it to extremes)
No hotlinking images please

Now if you want a fast CPU, fine. Dont bother me with your experience, come will data please.(Non of you have come with real data yet to prove me otherwise...)

One word for you COGNITIVE DISSONANCE.(Ok that were 2)

Read up, it might save you a couple thousand quid next time: http://en.wikipedia.org/wiki/Cognitive_dissonance

And lets get back to few arguments that were made:

Benefit from hyperthreading in games? - FALSE (I'm pointing at you Kaapstad)
Significant FPS boost in SLi setup for TS - Most likely false

Links/proof/evidence, Devion 2 or 3, rest 0.

We're talking about BF3 64 player multiplayer with two GPU's not Crysis 2 Single player.

I've noticed you talk a lot but then don't actually provide links to back up the point being discussed.

i7 helps with multi GPU in BF3 64 MP. End of discussion.

The increases in performance have been objectively recorded by numerous people on this forum. Whether it is worth it is another matter altogether .

I've seen the increase in GPU usage with my own eyes via monitoring software. You're digging so deep now you're starting to look ridiculous and your argument isn't coherent in the slightest.

 

[psychodil]

Isn't that two words?

 

[Gregster]

Soooooo us with experience of both set ups are wrong and Devion with no experience is correct. You are making yourself look silly here fella I am sorry to say.

 

[SkodaMart]

@Devion, you are making exactly the same mistake I made with BF3.
Up to around 50fps there is very little if any CPU limit on the game, even a Core i3 or so will run it at 50 fps.
When you start to add a 2nd graphics cards and framerates climb to the low hundreds, at certain parts of the game i.e. hectic multiplayer battles, the CPU becomes the limiting factor, not the GPU.
A few users on here have found through experience that a Core i7 gives better 'extreme' performance than a Core i5. I say 'extreme' as we are talking about 50fps and above, which is perfectly playable for most users.

You are very rude, if anything the two word expression you use above could actually apply to you.

I belive I have only mentioned one game BF3 and as several of us have stated for multi GPUs there is a performance increase when using an i7.

I also find it interesting that you are throwing out links to all sorts of other games to try and prove a point about BF3.

 

[SkodaMart]

This just isn't true.

I will admit that the Core i7 shows very little if no improvement over the Core i5 in many (most) games.

Even the 4 cores of the Core i5 are not fully utilsed in many games, that's why you see little or no improvement with an i7.

BF3 is one of the first games to my knowledge that is truly multithreaded.

The prime example of hyperthreading performance in multithreaded games is the core i3, it punches way above its weight for a dual core processor.

 

[Gregster]

For the record, FSX ran horribly on my I5 with SLI 680s and settings maxed out. Now on an I7 it runs sweet as a nut. Any explanation Devion?

 

[Rusty0611]

After I called him out on posting links to anything but multi GPU BF3 MP64 - errrr you know what we're actually talking about - he's scouring the Internet for something... SOMETHING!

An easy cure to not end up in a situation like he is: don't post when you ain't got a clue what you're talking about!

I do it (don't post) regularly on other subjects.

Then again my viewing over a large period in time of seeing the numbers 80-85% on my screen next to "GPU1 Usage" on my overclocked i5 to then suddenly 95-99% is errrr what again....

Cognitive dissonance.

Hmmm I'll have to read about the links between this and reading a number off the screen!

Nice strawmen, but I aint falling for it. YOUR argument is i7 helps with multi GPU in BF3 64MP, the only thing I said about BF3 multiplayer that shouldn't make difference because of single player AI calculation. But oke I can agree in mp64 there could be more difference....like this:

 

[Rusty0611]

Unsourced link... Old generation of graphics card.

I'm glad you've admitted it now.

Anyway, no-one was saying that the difference is large but as a matter of fact only: an i5 2500K even with a large overclock can bottleneck two high end GPU's

 

[SkodaMart]

The problem with the chart above is the framerates are still low we are talking about 100+fps.
Those lows of 44 and 47 have probably come from the graphics card not the CPU.

The HD 6990 is a dual GPU graphics card and both x-fire and SLi show lower 'lows' than a single card of the same power.

If I can make head or tail about that statement, you say we are wrong but then say we are right?

Really? I didn't think k that was the case at all.

If we are talking about the same game: http://www.tomshardware.com/reviews/core-i5-gaming,2403-10.html

Now I dont know what kind of ridiculous resolution your are running, which mostly should be GPU bound, but this game aint that heavy.

So....A monkey assembled your computer?

The prime example of hyperthreading performance in multithreaded games is the core i3, it punches way above its weight for a dual core processor.

Hyperthreading do not add real cores, they are merely virtual. Only very parallel threaded applications will benefit from it, especially not games.
