GeForce GTX 590 Key Features Revealed

An alleged partner presentation slide leaked to the internet reveals quite a bit more about the GeForce GTX 590 than what we already know. To begin with, it lays to rest speculations surrounding the shader configuration, each of the two GF110 GPUs have all 512 CUDA cores enabled. Next, the full width of the memory interface is utilized, giving you 1536 MB per GPU, or 3 GB of total memory on the card.

The rest are fascinating features, such as a removable cooler shroud that lets you clean the card from time to time (you might need to clean it now and then for the best cooling performance), heatsinks that use vapor-chamber technology, getting rid of those pesky heat-pipes, high-grade 12-layer PCB that uses 2 oz copper layers, and a 10-phase VRM (looks like 4+1 phase per GPU). As expected, the final iteration of the card needs to draw power from two 8-pin PCI-E power connectors. "Barely Street Legal"? Is it because they'll throw you out of LAN parties for having too much of a performance advantage? Hmmm.

What size is the 6990 fan, smaller than 80mm? The fan on the 590 looks to be bigger than that of the 6990, better cooling and less noise one hopes.

From the other thread I thought you said fan in the middle was a horrible design.

At least they have some understanding of the idea's of cooling, its less about heatsink size and more about airflow, heatsink size is more important that airflow when you're talking about being able to easily surpass a certain level of airflow like having pretty much any sized fan on a CPU heatsink, on a GPU airflow is so low that increasing it is the MOST important thing.

Gpu's tend to go for incredibly densely packed fins, which is less good for cooling as you're just slowing down airflow, not terrible on a radiator with huge fans and huge airflow already, but with a tiny amount of airflow the longer its in the heatsink the hotter it gets, the less well it cools.

ITs got a better fan and looks like smaller heatsinks to accomodate a bigger fan.

The removeable shroud is a very good idea but suggests that its right on the bring of cooling capcity and workable temps and any reduction in cooling capacity will be very bad for it.

How many cases will a 6990/590gtx end up in that don't have, lets say, 2-4 inches spare from the edge of the card to the side panel. Why not, is it MSI who is making the wider cards, make it a MUCH wider pcb, much bigger/wider/less airflow impeding heatsinks and a MUCH bigger fan in the middle. Always seems ridiculous how much space inside a case is completely unused and a decade later most components don't utilise the space.

expansion slots should have been made two tier years ago, can fit a normal sized card or a wider one, and gpu's should have been made way wider cards, would have dropped cost aswell as you could have less layered PCB's, better cooled gpu's with lower RMA rates which reflects in card cost.
 
This card is the last possible contender as a possible upgrade to my 5850's.

ATI 6*** and nvidia 5** series didn't offer enough boost to justify the price. The 6990 was the same.

If this isn't good enough, I'm most likely going to have to wait for the ATI 7***'s or fermi's successor.
 
This card is gonna be hot and loud of that i have no doubt. Nvidia are making a cooler designed to be cleaned which tells me that if dust gets in this thing will overheat pretty fast. The fan does look to be bigger than the amd 6990 so hopefully less rpm and a little less noise. We all know if nvidia want the performance crown they will have to run those gtx580 cores to pretty much full gtx580 clocks so there will be more heat coming from those gpu's than a 6990 produces so the cooler will have to be better than amds.

The card does look a little like a 6990 in design so i expect this card to have similar problems.

Correction I said the 6990 fan is a horrible design, the Nvidia fan looks way bigger so it won't be as much of a screaming banshee.

And you're getting this "screaming banshee" from the ONE review that somehow managed to get the fan spinning to 77db when no other review even got close to that?

Its amazing how when one review comes out with something obviously outlandish thats the one thats becomes the baseline and the one people talk about...
