[Various] Pascal Titan could be 50% faster than the GeForce GTX 1080 - Rumoured to launch in August - Page 29

i ask cause plan to buy a pascal titan and game at 1920x1200p.

The lower the resolution the faster the GPU can render frames, hence higher frame rates at lower resolutions. In the case of an uber powerful card like the Titan P it can render frames at 1080p in excess of 200 FPS which the CPU then has to match. If the CPU can't hold up to those high frame rendering times from the GPU then the video card is stuck sitting around waiting for the CPU to serve up the next frame and thus a CPU bottleneck. A card like the Titan P is really idiotic for 1080p gaming in the first place, however. If you want to hame at 1080p (even with a 144Hz monitor) you would be much better served with something like a 980 or 390X at the time being. Anything faster is just wasted on lower resolutions (unless benching)...

Not quite. Sometimes frame rates are dependent on other variables. Notice AMD cards lose less performance at higher resolutions and NVidia loses more performance at higher resolution. You're definitely onto something.

I think the pricing scheme for this card is going to be $1500-1800.

Aren't they coming out with a 1080P / 240Hz monitor this year?

If its true that Titan are ready by August / Sept, and mind you I dont mean paper launch, it can explain one thing:


TSMC yield are much better than 28nm when it first came out.

Tons of voltage regulator? Maybe this card will be the first to break the 2.1GHz barrier. Also the FE cooler is not even cutting it for 1080, a monster die like GP100 which is twice as big, definitely need TWICE the cooling capacity.


The PCB is probably designed excessively large to accommodate the giant heatsink.

to recap, there might not be a 1080 Ti, instead renamed as both Titan so Nvidia can price it through the roof:


Titan P - 3584 cores, 12GB HBM2, No DP, $999, AiB available

Titan P FE - 3840 cores, 16GB HBM2, 1/4 DP, $1499, Only FE

And maybe a 1080 Ti with 16 12 GB of GDDR5X later, for $800?

Nope, Given that GP102 and GP100 are same die but using different interlink interface, if GP102 is using HBM, Nvidia had to redesign a new core like GP103 to integrate the G5X controller instead of HBM.


That is very very unlikely, the cost to design a new core for the sake of G5X is just not worth it.

Are we sure GP102 is for a different interlink? The TechPowerUp post today seems to suggest the new Titan is GP100, but who really knows? tongue.gif

The GP100 and GTX TITAN P isn't the only high-end graphics card lineup targeted at gamers and PC enthusiasts, NVIDIA is also working the GP102 silicon, positioned between the GP104 and the GP100. This chip could lack FP64 CUDA cores found on the GP100 silicon, and feature up to 3,840 CUDA cores of the same kind found on the GP104. The GP102 is also expected to feature simpler 384-bit GDDR5X memory. NVIDIA could base the GTX 1080 Ti on this chip.
