NVIDIA GeForce GTX 1070 Ti (Desktop) vs NVIDIA GeForce GTX 1080 (Laptop)

NVIDIA GeForce GTX 1070 Ti (Desktop)

The Nvidia GeForce GTX 1070 Ti is the second fastest Pascal based graphics card in November 2017. It is a high-end desktop graphics card based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. Compared to the GTX 1080, it uses the more available GDDR5 graphics memory, and compared to the GTX 1070 it offers more shaders (2432 versus 1920). More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

The performance of the GTX 1070 Ti was in our tests right between the GTX 1070 and GTX 1080. However, the powerefficiency was worse than the GTX 1070 and near the GTX 1080. Nvidia also specifies the 1070 Ti and 1080 at 180W.

NVIDIA GeForce GTX 1080 (Laptop)

The Nvidia GeForce GTX 1080 for laptops (formerly known as GTX 1080M) is the mobile counterpart of the desktop GeForce GTX 1080. It uses the same GP104 chip and was officially announced at 16. August. The performance should be around +-10% of a non overclocked desktop GTX 1080. The amount of shaders and other technical specifications should be identical.

The mobile GTX1080 is the successor to the GeForce GTX 980 for Laptops and offers a significantly higher performance at the same TDP.

For thin and light laptops Nvidia offer a Max-Q called version of the GTX 1080 with lower TDP and also significantly lower performance. Sadly this variant im sold with the same GTX 1080 name, making it hard to judge the performance.

The performance depends on the used thermal headroom, processor and game. In our benchmarks the mobile GTX 1080 was between 0 to 10 percent slower than the desktop GTX 1080. Therefore, the card also allows gaming in 4k for modern and demanding games of 2017. However, the performance depends on the cooling and TDP settings in each laptop. E.g. the MSI GT73VR (200 W TDP) is much faster than the 1080 in the Razer Blade Pro (<=150 W).

The GP104 chip is manufactured in 16nm FinFET process at TSMC and offers a range of new features. DisplayPort 1.4 (ready), HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP), improved H.265 video en- and decoders (for PlayReady 3.0) are only some of the improvements. See our detailed Pascal architecture article for more details.

Due to the high TDP, the mobile GTX 1080 is only suited for large laptops with high performance cooling solutions. The power consumption is ranging from 150 to 200 Watt (according to Nvidia, up to 220 W in the Asus G701VIK, G800, GX800). A low power version (Max-Q) is available beginning summer 2017 with a reduced TGP of 90 - 110 Watt (at a reduced performance).
