New GPU nVidia "Pascal"

So here we are again with some nVidia news following the recent GPU Technology Conference they have given us a tasty look at the new "Pascal GPU" with very little in the way of full details, although what we have been shown is enough to get our OC3D tongues wagging.

So here's what we know.

Code name: "Pascal"
Features known include: NVLINK giving us between 5 - 12X PCIe 3.0 and 3D Memory allowing for 2 - 4X the normal memory bandwidth
and the obvious thing is the size it's simply tiny almost 1/3 the size of a standard PCIe card.

3D Memory: Stacks DRAM chips into dense modules with wide interfaces, and brings them inside the same package as the GPU. This lets GPUs get data from memory more quickly – boosting throughput and efficiency – allowing us to build more compact GPUs that put more power into smaller devices. The result: several times greater bandwidth, more than twice the memory capacity and quadrupled energy efficiency.
Unified Memory: This will make building applications that take advantage of what both GPUs and CPUs can do quicker and easier by allowing the CPU to access the GPU’s memory, and the GPU to access the CPU’s memory, so developers don’t have to allocate resources between the two.
NVLink: Today’s computers are constrained by the speed at which data can move between the CPU and GPU. NVLink puts a fatter pipe between the CPU and GPU, allowing data to flow at more than 80GB per second, compared to the 16GB per second available now.
Pascal Module: NVIDIA has designed a module to house Pascal GPUs with NVLink. At one-third the size of the standard boards used today, they’ll put the power of GPUs into more compact form factors than ever before.
Pascal is due in 2016.




So what are our thoughts?

Nice, stacked memory will be brilliant on GPUs.

Dat Bandwidth, all Dat Bandwidths. It will be great for future high res gaming setups.

Very good idea with the watermarks Keep up the good work!

This is very interesting, not what I really was expecting.

first thing i did was look down at the calculator beside me and go "damn thats so small it would fit inside that and i could play games in school. a passively cooled one of those could be amazing though if its heat output is low enough..

A module? I wonder how it interfaces with the PC.

An aside note, I can't get any of the streams to work

2016 is a way off but if this is what is planned then things look like they are in for a big change. If Maxwell is 20nm (if they decided not to skip 20nm) then "Pascal" is most likely going to be 16nm.

Volta is still on the roadmap, although it's delayed until something like 2016. TSMC's fault apparently.

I wonder how AMD retaliates, or rather, their ability.
