NVIDIA GeForce GTX 1070 SLI (Laptop) vs NVIDIA GeForce GTX 1050 Ti (Desktop) vs NVIDIA GeForce GTX 1080 Mobile

NVIDIA GeForce GTX 1070 SLI (Laptop)

The Nvidia GeForce GTX 1070 SLI for laptops is a combination of two GTX 1070 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1070 to up to 90% faster performance. In most games with SLI support, the GTX 1070 SLI is therefore faster than a single GTX 1080. However, sometimes the combination also suffers from micro-stuttering.

The technical details of the card are identical to a single GTX 1070 (see for more information) and the power consumption is doubled. Therefore, the 1070 SLI combination is only found in huge clunky laptops.

NVIDIA GeForce GTX 1050 Ti (Desktop)

The Nvidia GeForce GTX 1050 Ti (N17P-G1) for desktops is an entry level gaming graphics card that was announced late 2016. It is based on the GP107 chip using the Pascal architecture and manufactured in 14nm FinFET at Samsung (the bigger Pascal chips are manufactured in 16nm at TSMC). Usually it is equipped with 4 GB GDDR5 memory with a 7 Gbps data rate. The mobile GTX 1050 Ti version should be announced later (beginning of 2017) and feature similar specs.

The performance of the GTX 1050 lies between the Radeon RX 460 and the RX 470 on a similar level of the old GeForce GTX 960 (or 970M). Therefore, the card is most suited for 1080p gaming at high detail settings (but not maximum settings).

See our extensive review of the MSI GeForce GTX 1050 Ti for more information on power consumption, benchmarks and noise level.

NVIDIA GeForce GTX 1080 Mobile

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).
