It appears that the release of NVIDIA’s GeForce GTX 1080 and GTX 1070 GPUs are not going to be limited to gamers who have desktop systems. Most likely, the company is going to be mixed in the affairs of future OEMs in order to release powerful gaming notebooks that sport the same GPU, at least when the name calling is being involved.
Mobile Version Of GeForce GTX 1080 Has Its Specifications Leaked – GDDR5 Instead Of GDDR5X With Lowered Memory Bandwidth And Possibly Better Efficiency
If you take a look at the leaked image below, the alleged mobile version of GeForce GTX 1080 features 2048 CUDA Cores, which is less compared to the 2560 CUDA Cores present in the desktop variant. The mobile version of this GPU is based on the new Pascal GP104 SKU and it’s highly possible that it will feature a lower TDP compared to the desktop version. The desktop version of GeForce GTX 1080 is running at a default clock speed of 1607MHz, while the one that could be running in future laptops is running at a speed of 1442MHz.

Unfortunately, the Boost Clock details have not been specified, but our guess is that in order to pay more focus to slightly more battery life, there is not going to be a significant amount of difference between the Core Clock speed and Boost Clock. Another detail that might have missed your eye was the fact that this particular model has a lowered memory bandwidth (256GB/s) than the desktop model (320GB/s) which begs the question that the mobile version could feature GDDR5 type video RAM instead of the higher bandwidth capable GDDR5X.

The memory clock is also rated to run at 8008MHz, which is lower than the 10,000MHz memory clock of the desktop version, again signifying the performance sacrifices that have to be incurred in order to conserve battery life. Fortunately, the supposed mobile version features the same amount of video memory (8GB), which will encourage future manufacturers to incorporate 4K displays onto their gaming machines to provide the best possible immersions. We have detailed the differences between each variant so you have a small idea of what sort of performance to expect (this will also include ROPs and TMUs):
