Pascal 10x Maxwell? Where you going with this, Jen?
It's going to have 2 TFLOPs DP compared to the .2 on the Titan X
lol

That robot car was founded by DARPA? Do you guys think they got a secret version of the car with a gun on top working yet?
Put together some Pascal details:
- first NVIDIA GPU with 3D memory and NVLink
- 32GB of memory
- 3x the memory bandwidth of Maxwell
- 2x the performance per watt of Maxwell
- new feature: mixed-precision
- 4x the mixed-precision FP16 performance of Maxwell
Anything to add or change?

Is it really worth upgrading from my 980 for gaming purposes? Finding it difficult to justify the price for the performance the Titan gives over the 980, it seems a small increase based on leaked benchmarks.

Or maybe I'll hold on to my Titan Black until Pascal o_o
"2016"
Added to the list in the OP, along with the slides.That 32 is only max potential capacity btw.

If pascal next year is 10x it kinda makes spending a whole bunch of money on titans very undesirable.
I was ready to buy a Titan X, but after this Pascal thing I'm not sure anymore.
AFAIK Nvlink is the interposer for the "3D" memory.Any more information on Nvlink? Is it going to work on existing motherboards? What will be the vendors that make it? Etc.
same lol
but it could be like end of 2016 so I'm like man that is a long wait lol

But the rabbit hole goes deeper. To pull off the kind of transfer rates NVIDIA wants to accomplish, the traditional PCI/PCIe style edge connector is no good; if nothing else the lengths that can be supported by such a fast bus are too short. So NVLink will be ditching the slot in favor of what NVIDIA is labeling a mezzanine connector, the type of connector typically used to sandwich multiple PCBs together (think GTX 295). We havent seen the connector yet, but it goes without saying that this requires a major change in motherboard designs for the boards that will support NVLink. The upside of this however is that with this change and the use of a true point-to-point bus, what NVIDIA is proposing is for all practical purposes a socketed GPU, just with the memory and power delivery circuitry on the GPU instead of on the motherboard.
NVIDIAs Pascal test vehicle is one such example of what a card would look like. We cannot see the connector itself, but the basic idea is that it will lay down on a motherboard parallel to the board (instead of perpendicular like PCIe slots), with each Pascal card connected to the board through the NVLink mezzanine connector. Besides reducing trace lengths, this has the added benefit of allowing such GPUs to be cooled with CPU-style cooling methods (were talking about servers here, not desktops) in a space efficient manner. How many NVLink mezzanine connectors available would of course depend on how many the motherboard design calls for, which in turn will depend on how much space is available.
One final benefit NVIDIA is touting is that the new connector and bus will improve both energy efficiency and energy delivery. When it comes to energy efficiency NVIDIA is telling us that per byte, NVLink will be more efficient than PCIe this being a legitimate concern when scaling up to many GPUs. At the same time the connector will be designed to provide far more than the 75W PCIe is specd for today, allowing the GPU to be directly powered via the connector, as opposed to requiring external PCIe power cables that clutter up designs.
With all of that said, while NVIDIA has grand plans for NVLink, its also clear that PCIe isnt going to be completely replaced anytime soon on a large scale. NVIDIA will still support PCIe in fact the blocks can talk PCIe or NVLink and even in NVLink setups there are certain command and control communiques that must be sent through PCIe rather than NVLink. In other words, PCIe will still be supported across NVIDIA's product lines, with NVLink existing as a high performance alternative for the appropriate product lines. The best case scenario for NVLink right now is that it takes hold in servers, while workstations and consumers would continue to use PCIe as they do today.
Meanwhile, though NVLink wont even be shipping until Pascal in 2016, NVIDIA already has some future plans in store for the technology. Along with a GPU-to-GPU link, NVIDIAs plans include a more ambitious CPU-to-GPU link, in large part to achieve the same data transfer and synchronization goals as with inter-GPU communication. As part of the OpenPOWER consortium, NVLink is being made available to POWER CPU designs, though no specific CPU has been announced. Meanwhile the door is also left open for NVIDIA to build an ARM CPU implementing NVLink (Denver perhaps?) but again, no such product is being announced today. If it did come to fruition though, then it would be similar in concept to AMDs abandoned Torrenza plans to utilize HyperTransport to connect CPUs with other processors (e.g. GPUs)

That sounds accurate.Put together some Pascal details:

NVlink is an interconnect. It will be used in the two largest supercomputers in the upcoming years, currently being built by IBM and NV.I thought NVLink effectively replaces PCI-E as the BUS for the GPU? In which case all new motherboards with NVLink ports would be necessary.
