The GT300/Fermi Thread - Part 2!

[saaya]

Several of my contacts there (marketing, development, etc) have risen through the ranks over the years I have been talking to them so I don't know where you gotyour info from.

forgot the name of the website... its the no1 site where employees rate and review the companies they worked or work for, plus they give their ceos approval ratings.

As you increase the performance of a GPU, the CPU naturally needs to be faster to feed it information at a quick pace. However, as these GPUs quickly outpace game development, the CPU will continue to be a bottleneck all the way into high instances of AA. Luckily, it seems like DX11 has moved less emphasis off of the CPU which bodes well for the future.

yeah i know... so what do you think? will fermi need a fast cpu or not? they showed it off with a 960...

This really depends on how good of a heatsink NVIDIA sticks on it. I have a feeling though that the combination of 8-pin / 6 pin power connectors and the PCI-E 2.0 slot will be able to provide more power than even an overclocked GF100 can ask. Naturally, when you get into areas like voltage tweaks the consumption of any component will skyrocket.

well if the tdp numbers i heard are true, then its 50W more than a 285... and thats really a lot... i cant imagine what kind of a heatsink that occupies 2 slots is needed to keep that cool... i just wondered if that was only early silicon and if the newer stuff is running cooler...

No it isn't. With AFR each frame is handled completley by either GPU1 or GPUn.

And since the memory is mirrored for both GPUs, you effectively have the same amount, speed, bus width and bandwidth of the single GPU counterpart.

thats not true, while a frame gets rendered there is constantly data written to and read from the mem... and that is NOT mirrored between the two gpus... otherwise both frames would end up identical...

both gpus get the same raw data, i guess, but they then use their memory and memory bandwidth independantly... if they would really mirror each others memory then you would have to split the memory into 2 partitions and the effective memory per gpu would actually drop in half
but why would you do that? why does gpu1 need to know what that gpu is doing with the data and what its frame will look like?

It's not just the consumers, also the shop managers often have no clue about various brands and models of hardware. Whenever I see one of them 'helping' one of the customers... I really wish I wouldn't hear what they were suggesting.
So no wonder renaming works for Nvidia so well.
Most people only look at the numbers... model number, price, VRAM amount, that's it. And a lot assume that the more they pay the better product they get... So there is a lot of room for ridiculous pricing, and people are more than happy to buy such stuff.

its even worse, ive seen several sales people in shops telling people marketing nonsense i could SEE they knew was not true... but they dont care, they want to sell their stuff... i can understand it, but i wouldnt do it...

There are little to no constructive posts found in this thread, hence my post in my opinion is valid. It's just the same old same old rehashed over and over again. Now it's even more of a load of rubbish with even less info.

Forums would exist, and they would be a lot more interesting if people would post some more 'useful' things.

Every day I check this thread and it's bla bla this bla bla that. It's probably because Fermi is so late that I just can't bear this stuff anymore, usually it isn't as bad and actually quite entertaining sometimes, because there is actually stuff to discuss. Now there is nothing much to discuss anymore, and people still keep yapping.

idk, i consider this an offline chat... as soon as something interesting is discussed i go back a page or two to catch up on what happened... i prefer too much info over not enough info that somebody thought was not important... and besides, even if there is no or little info, its fun to talk to others about tech, the companies that make them, their products...
