So I recently took a look under the hood of my reference 670 and man are the PCBs on these cards tiny. I compared it side-by-side to my 580 and I just don't understand how something with half the surface area and components can produce ~20% greater performance. I know that the nanometer shrink was a big factor but is there an explanation in layman's terms as to how these Chode-GPUs came to be?  Pic related: Chode-GPU

I'm not one of these people who can tell you exactly why, I'm sure a more knowledgeable person will chime in but I'm going to guess the less power hungry GPU + Smaller Die = to lesser PCB needed.

I see quite a bit of wasted space on the right side of that 570... That picture of 570 also has 2 more dimms.

I find this offensive. It's not size that matters it's...eh...motion of the graphics! Plus they have a great personality...

Personally I hate these small PCB's. The larger PCB's are much more rugged and less prone to warping over time.

It came to be by Nvidia cutting a GTX 690 PCB in half.

This seems like backwards thinking. A PCB is relatively thing and the longer it is the more strain is put on the card's structure, as regardless of length it is still being supported by the same PICE slot/Screws

Exactly what I thought when I read that post. The shorter it is, the less prone to bending it would be. I would love if all GPU's were smaller.

Only clicked cause the title said "chode". I should probably feel bad about that.

I would totally be down if there was GPU sockets on the mobo with GDDR memory slots.

The PCB on the reference 670 is about the size of a HTPC GPU in size. But then they go and stick that reference blower cooler on it and lengthening it to a normal size GPU like they're trying to hide the fact that its smaller then it really is. You know like the guy with the sports.......nvm.

This kind of thing happens all the time with the mid range cards like the 460 and 560, they start with a nice looking pcb and once the card is going out of fashion, they strip every thing off it and just keep what is needed to run the card.

Ok I can help here :)
Main Factors that allow these to be smaller:
1). Smaller memory buss width. The 670 has a 256bit memory buss as oppose to the 580's 384bit. A large memory buss requires a larger card to accommodate the extra 128 data lines that connect to the memory. Also it's not a 1:1 increase in size since the lines must be routed in a way that keeps timing correct, and cross talk at a minimum. Larger mem buss always = larger more complex card.
2). Power consumption. The 670 uses far less power than the 580. This means the VRM (voltage regulation module) section can be smaller, and less complex. Also smaller & less capacitors can be used since there will be a lower voltage drop across the power planes.
3). The GK104 GPU chip is physically smaller than the 580's GF110 due to the 28nm process.
All this allows a smaller, faster, and more efficient card.
Also this allows Nvidia, and companies like EVGA higher profit margins, since the cards cost far less to produce.
