New GPU nVidia "Pascal"

Wraith

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 :D 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..
 
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.
 
Sounds impressive but in practice I don't think we will see huge gains.

4x memory bandwidth and NVLink won't do anything much unless there is a very big jump in GPU performance. Remember PCI-E 3.0 is more than fast enough for todays uber 4 way setups.

One thing Mantle has shown recently is even if you have fast hardware, it can be crippled by rotten software (DX11).

One that is really interesting is the size of Pascal but is small really that desirable when dealing with getting rid of heat if an uber GPU is used to match the rest of the setup.

Nail & Head! This is the only problem these days nVidia & AMD both release far too much too often, meaning were having to wait for new driver updates but they all seem to forget it's the GUI that needs attention.

i.e My old Athlon 4400 with a Radeon x1300 Pro ran Unreal Tournament III perfectly at full settings, only because it was it was developed using similar hardware and yet my current rig struggles with it.
 
The stacked vram modules within the gpu chip area is definitely the most exciting part to this Pascal architecture. 4k resolution with ease!

But lets see if Pascal can double what Keplar GK110 can crunch before anyone should get excited... as then we're really getting somewhere :D

As for NVLINK a new CPU/GPU interface is inevitable. It appears more as nVidia posturing to get the industry as a whole dancing to their (and IBM's) tune. Should we consumers get the interface, struggling to wonder why we would require such bandwidth [more than 4 gpus within a system would be nice], is there a reason to go for x99/z97? Reminds me of AGP -> PCI-E foray.
 
yea i seen this an thought they had just renamed volta but thats not the case. it is its own thing completely. not sure ho i feel about breaking from a standard
