Alleged specifications and benchmarks of NVIDIA’s upcoming GeForce GTX 1080M mobility graphics chip have been leaked by Videocardz. The GeForce GTX 1080M has been part of our headlines for the past few weeks and from the looks of it, it will become the flagship Pascal offering for the mobility market and will utilize the GP104 architecture to deliver unprecedented performance increase in high-end, enthusiast grade laptops.

NVIDIA GeForce GTX 1080M – Flagship Pascal Mobile GPU With 2048 CUDA Cores, 8 GB G5 VRAM

The NVIDIA GeForce GTX 1080M is already shipping to several OEMs and one such company decided to post a few leaks. The GeForce GTX 1080M is going to replace the GeForce GTX 980 (mobility) graphics card and while both chips would look very similar in terms of specifications, the Pascal variant will be performance leap as the card does feature better core performance and pumped up clock speeds while featuring insane efficiency specs.

NVIDIA GeForce GTX 1080M and GeForce GTX 980 (Mobility) Specs Comparison

For starters, the GeForce GTX 1080M features 2048 CUDA cores, 128 TMUs and 64 ROPs. The GeForce GTX 980 also features 2048 CUDA cores, 128 TMUs and 64 ROPs. The GeForce GTX 1080M would feature 8 GB of GDDR5 memory and guess what, the GeForce GTX 980 also features 8 GB of GDDR5 memory. The difference lies within the internal architectural differences that deliver better per core performance and faster clocks.

The GTX 1080 M features clock speeds of 1442 MHz base and 1645 MHz boost clocks while the GTX 980M features core clock of 1064 MHz base and 1228 MHz boost. The memory on the GeForce GTX 1080M also clocked to 8 GB/s which delivers 256 GB/s bandwidth compared to just 224 GB/s on the GTX 980M with its 7 GB/s memory.

The GeForce GTX 1080M could feature a TDP around 150W which was same for the GeForce GTX 980M. The card will be further tuned to deliver better battery times on high-end laptops but its better to use such device plugged in to a socket while gaming. This leads us to the performance numbers of the GeForce GTX 1080M.

NVIDIA GeForce 1080M vs GeForce GTX 980 (Mobility) Graphics Performance

The same source posted a 3DMark Firestrike score of the GeForce GTX 1080M which scored 16893 points in the synthetic benchmark. The GeForce GTX 980 (mobility) in comparison scores 13125 points in the same synthetic bench. A reference GeForce GTX 980 Ti in comparison scores 16905 points which shows that this card is just as fast as the previous generation flagship graphics card from NVIDIA. Following is a the 3DMark Firestrike graphics score for various high-end graphics cards courtesy of PCPerspective:

While we have some information at hand regarding NVIDIA’s upcoming GPU launches for the mobility sector, we still don’t have a confirmed launch time frame for these cards. The GeForce GTX 1080M was tested inside laptop that looks finalized and is a beefy design in general. Just a few days ago, we covered a high-end laptop listing which featured the GeForce GTX 1080M discrete graphics chip, find out more on that here.

The GeForce 1080M would be using the same PCBs that were designed to support the full GM204 GPU offering higher voltage control and better overclock capabilities. NVIDIA has already taken in control the flagship single-chip performance crown in the desktop market and they would be doing the same withe GeForce 10M series in the mobile sector.
