Key components of the GeForce GTX 1080.
I think it makes sense for nVidia to integrate the G5X memory since, from what I gather in reports previously, it's inexpensive to integrate them without any or all significant changes to the PCB itself for greatly improved bandwidth. Still, real world usage will hopefully reveal just how much of an improvement we'll be receiving this time around. Either way patience might pay off if or when a Ti cards come up later and I'd say it will very much be worth the wait
From what I read elsewhere, GDDR5X has a completely different pinout to GDDR5, meaning a different PCB layout.
I wonder if the GP104-400/GDDR5X will be the GTX1080, and the GP104-200/GDDR5 being the GTX1070?
This may mean that Nvidia are saving the Ti suffix for a later 16GB HBM2 version.
It does not seem to match any of the known GDDR5X chips from I read on another forum.
The serial numbers on the RAM don't seem to match any known serial numbers so one things for sure, it's new. :)Quote:

Here are the samples Micron are shipping from last month:

The first GDDR5X memory chips from Micron are marked as MT58K256M32JA, feature 8 Gb (1GB) capacity, and are rated to run at 10 Gb/s, 11 Gb/s and 12 Gb/s in quad data rate (QDR) mode with 16n prefetch. The chips use 1.35 V supply and I/O voltage as well as 1.8 V pump voltage (Vpp). Micron’s GDDR5X memory devices sport 32-bit interfaces and come in 190-ball BGA packages with 14×10 mm dimensions. As reported, the GDDR5X DRAMs are manufactured using 20 nm process technology, which Micron has been using for over a year now.
PCB differences are minimal - wonder if Micron have managed to turn out a highly tuned set of GDDR5 with higher clock rates.
As to GDDR5X, the big selling point was that it didn't need extensive retooling of your designs to use it: it's meant to be close to plug-and-play compatible with GDDR5. I'd be surprised if the pin-outs were that different; needing different PCBs for '5 and '5X designs would negate one of the big USPs...
The main thing is if the GP104 is using GDDR5X,any SKUs will be hard to get - Micron has stated mid-year for mass production,so I expect most if not all GP104 based cards launched in summer would probably use GDDR5,or at least the ones which can be actually bought in any volume.Quote:

Hmm so the Ti will get GDDR5x and the standard 1080, and therefore presumably the 1070 will get GDDR5 by the looks of things. So just an architecture change this time round. Would've thought theyd use HBM2 for the 980ti, but if theyre looking for simultaneous june release like the 900 series, its probably nowhere near ready for that.
I'll wait and see how big a difference the new architecture makes then.
These should perform well even without HBM2 DRAM. They also look like excellent upgrades for anyone running GTX 600 or 700 series cards.
Am planning to get my first Nvidia card... the GTX 750ti because it does not require a beefy power supply, how does it perform in rendering tasks like 3DS max and Adobe premier pro?
I really don't know about that - we haven't seen anything about GP104 - we have seen titan with its FP64 compute , but if what I read a while ago is true - retail cards are beefed up Maxwell with `proper` pascal next year.Quote:

That said, a 950 or even a 960 shouldn't be much of a strain on any PSU.Quote:

gtx 750Ti is Maxwell - 1st gen Maxwell , whislt gtx 9xx are second gen.Quote:
