NVIDIA GeForce GT 1030 (Desktop) vs NVIDIA GeForce GTX 970M vs NVIDIA GeForce GTX 1080 Mobile

NVIDIA GeForce GT 1030 (Desktop)

The Nvidia GeForce GT 1030 (sometime GTX 1030 called) is an entry level dedicated graphics card for desktops. It is based on the GP108 chip using the Pascal architecture in 14nm FinFET. It features three streaming multiprocessors (SMs) and therefore 384 shader cores, 24 texture units and 16 ROPs. The 2 GB GDDR5 memory are connected with two 32 Bit memory controller (48 GBit/s). The shaders are identical to other Pascal cards like the GTX 1050 and therefore also the support for DirectX 12 FL 12_1.

The performance is slightly below the Radeon RX 550 from AMD and therefore only suited for low to medium detail settings of modern games like Battlefield 1.

The TDP of the GT1030 is specified as 30 Watt.

NVIDIA GeForce GTX 970M

The NVIDIA GeForce GTX 970M is a high end DirectX 11.2 graphics card for laptops. The card is not yet officially announced and therefore the following information is based on rumors and leaks. The card based on the GM204 Maxwell chip, that is already available in the desktop GeForce GTX 970 and 980. Thanks to the improved efficiency, the GTX970M should be clearly faster than the previous GTX 870M and even the old GTX 880M.

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).
