GeForce Titan coming end of February

So i cant personally Overclock a GTX660??

Who do you think you are? idiot.

For a start a 690 GTX has 2 x 256bit memory bus which is MORE than a single 384bit bus. So basically a single 7970 has just as much bandwidth as this titan. A 7970 CF has double the bandwidth and the same Vram.

IF you actually understood my post you would see that i said its all about single or dual GPU setup. So how its that backward or illogical.

And single cards do have stutter issues its been all over this damn forum

You seem to have forgotten that with SLI/CF nothing is doubled. Each GPU is working on its own frame and accesses its own memory bus. So you really don't understand AFR.

Aside from that he is right. SingleGPU > AFR, especially CF. There may be some stuttering occasionally with singleGPU, but with AFR, it is basically the norm if you go below a certain fps threshold. I don't own any game where AFR below 45-50fps is really enjoyable and completely smooth. It is stupid to reduce performance of AFR-setups to fps only - but that is exactly what you did.

You can't touch the voltage. (which has been possible in most high end cards and still is in certain, but not all AMD cards)

They sold Lightnings with the ability to raise the voltage and later on NV blackmailed them into removing voltage increases or they wouldn't give MSI any warranty on their chips (or something similar, there's been threads on this).

 

[bunnyfubbles]

Probably will.

The world is full of idiots with more money than sense.

This forum is full of em.

world is also full of people with bitter jealousy

this thread has at least one

And by the look at that "barely capable of Tettris PC" you have it must be you!:twisted:

hmm...oh wait a sec...yikes! that's a Fat Rig you have there Bunny.:biggrin::thumbsup:

 

[psolord]

Wow are you dumb. In sli and cfx the second chips memory is just a copy of the firsts. So in effect you have 256bit on the 690

The framebuffer is mirrored indeed, but that does not mean the effective bandwidth is halved as well. You do get 2X256 bits on the 690 alright.

 

[boxleitnerb]

There is no "effective bandwidth". Each GPU is working on its own. You will definitely not see the same bandwidth/fps characteristics on AFR that you would see with a single GPU. The point is: The GPUs are completely independent from each other, and only when they are done with their respective frames, their work is put together. That is a big big difference from one GPU.

Why isn't there an effective bandwidth?

In AFR one gpu renders one frame, while the other renders the next, is it not? So in a 60 frame period, in one sec, the dual gpu card will have used one framebuffer 30times and the other framebuffer another 30times. It surely is not the same as if it had one 256bit framebuffer (in 690s case) that would have to be used 60 times.

So the overall bandwidth available every second is indeed 2x 256bits x clock frequency.

In AFR everything is double except memory size.

Yeah they pretty much cut the balls off of MSI.

Isn't the record on a 680 like 2100 on the core?

 

[boxleitnerb]

It makes no sense to define an "overall" value for bandwidth etc. because the GPUs are not working on the same problem.

Think of it this way:
Some performance characteristic, like memory bandwidth for example, might have a critical value below which performance tanks. Let's say for 1 TFLOP/s of computing power you need 100GB/s of memory bandwidth to have a balanced system for a given scenario.

Single GPU:
1 TFLOP/s and 100GB/s per GPU and overall. 10 FLOPs/byte

Dual GPU@half memory clock speed:
1 TFLOP/s and 50GB/s per GPU.
2 TFLOP/s and 100GB/s overall. 20 FLOPs/byte (per GPU).

Overall the AFR-setup has the same of more resources, but in certain cases half the memory bandwidth/FLOP might brake things. The balance of resources has to be right per GPU, not per AFR-GPU system.

Must be this Tuesday, EK already has their Titan waterblock listing up.

I'm selling /shameless plug

Going towards my Titan funds.. qq



You can only sell in the FS/T forum.

No shameless plugs allowed

It's against forum rules actually. You can only post that in FS/T. For example, I could say I have two GTX 690s for sale, but I can't. It's against forum rules.

I can't post over there I'm too noob btw, is this the same Adam from rage? Whatsup guy!

Exactly. But it's not against forum rules to say I sold both of my 680's over at the [H] and I'm ready to buy 2x Titan.

Very nice, 1 titan will be enough for me. Unless they produce more, I may add another later on.

 

[Black Octagon]

Dude seriously, wait for reviews before you purchase!

 

[DooKey]

Dude seriously, wait for reviews before you purchase!

Why? There's no doubt that 2x Titan will perform better than my 2x GTX 680's did.

 

[CurrentlyPissed]

Dude seriously, wait for reviews before you purchase!

How is anyone purchasing yet?

 

[blackened23]

Dude seriously, wait for reviews before you purchase!

The reviews will hit the net prior to cards going up for sale if i'm not mistaken, according to what i've read - Reviews are the 18th at midnight (I believe) and the cards should hit retailers the week after.

People who don't like nv: "It's loud, hot, big, expensive, etc"

Everyone else: "So what, don't buy it if you don't want the bleeding edge best."



There, I just saved everyone from reading the de-railed launch reviews thread.

I post there from time to time.

LOL!!! Perfect, just perfect. Waiting for that.

So it's OK not to buy their hardware as long as you don't say anything bad about them publicly. What fanboy idiot logic...
