Nvidia GTX 1080 Press Slides and Full Specifications leak
Insider slides and full GPU specifications of Nvidia's GTX 1080 have been leaked, offering a lot of new information on the GPU and the Pascal architecture.
First, we have a full GPU diagram, showing that the GTX 1080 will use the full GP-104 GPU core and has not been limited in any way by Nvidia. This means that Nvidia will not be releasing a GP-104 based GPU that is superior to the GTX 1080 in the future.
The full specifications of the GTX 1080 have also been revealed, revealing the GPUs ROP count TMU count and several other new details.
One thing to note is that the GTX 1080 has a transistor count that is closer to the GTX 980Ti than the GTX 980 while having a die size that is actually smaller than the GTX 980. This shows how much Nvidia can pack into a small space with TSMC's 16nm FinFET processing node.
GTX 1080 | GTX 980Ti | GTX 980 | |
GPU Architecture | Pascal | Maxwell | Maxwell |
Process node | 16nm | 28nm | 28nm |
SP FP Performance | 9 TFLOPs | 5.63 TFLOPs | 4.61 TFLOPs |
Die Size | 314mm2 | 601mm2 | 398mm2 |
Transistors | 7.2 Billion | 8.0 Billion | 5.2 Billion |
TMUs | 160 | 176 | 128 |
ROPs | 64 | 96 | 64 |
CUDA Core Count | 2560 | 2816 | 2048 |
VRAM Type | GDDR5X | GDDR5 | GDDR5 |
VRAM Cappacity | 8GB | 6GB | 4GB |
Memory Speed | 10Gbps | 7 Gbps | 7 Gbps |
Memory Bus Size | 256-bit | 384-bit | 256-bit |
Memory Bandwidth | 320 GB/s | 336.5 GB/s | 224 GB/s |
Base clock speed | 1607MHz | 1000MHz | 1139MHz |
Boost clock speed | 1733MHz | 1076MHz | 1240Mhz |
TDP | 180W | 250W | 165W |
Power Connection | 1x 8-pin | 1x 8-pin + 1x 6-pin | 2x 6-pin |
PCI Express | PCIe 3.0 | PCIe 3.0 | PCIe 3.0 |
The GTX 1080 will include GDDR5X memory, giving the GPU significantly more memory bandwidth than the GTX 980, but when it comes to pure memory bandwidth you can see in the table above that the GTX 980Ti actually beats the GTX 1080.
While on paper it may seem that the memory bandwidth of the GTX 1080 has been downgraded, but Nvidia has worked hard to improve how Pascal GPUs use the available memory bandwidth, using Fourth Generation Delta colour compression to deliver around 1.2x the effective bandwidth of previous generation compression methods.
While details on Nvidia's new HB SLI bridge is still pretty scarce, these new slides from Nvidia do show some of the potential benefits. According to Videocardz Nvidia only recommend their new high bandwidth SLI bridge for high resolution 1440p screens or higher resolutions, as this is where the additional bandwidth will benefit gamers most.
These new SLI bridges allow Nvidia GPUs in SLI to better communicate with each other, reducing frametimes and increasing framerates slightly while also decreasing frametime variance, giving SLI users a smoother gaming experience.
These new slides also mention that Nvidia are adding HDR support to their pascal GPUS and are offering Asynchronous compute compatibility, which is something that nvidia has been lacking with Maxwell.
This is all still early leaked data, so some of the data on these slides could change before they are officially released to the public.
You can join the discussion on the GTX 1080's launch slides and full specifications on the OC3D Forums.

Counting the ROPs, TMUs and cores, it's not exactly a 980TI/Titan X killer, is it? Going by my napkin math, a well overclocked 980TI (>1450MHz) will easily keep up with it in real world games (clock-for-clock, it's about 75% of the performance of a 980TI), maybe even surpass the 1080 in DX11 titles. I'm waiting for "Big Pascal", this doesn't impress me much, and unless you're going balls deep into VR, don't sell off your high-end Maxwell cards.
