NVIDIA GeForce RTX 2070 Mobile vs NVIDIA GeForce GTX 1080 (Desktop)

The NVIDIA GeForce RTX 2070 for laptops is the second fastest mobile graphics card for notebooks in early 2019. It is based on the desktop RTX 2070 but with reduced core speeds (-11% Boost, -14% Base). The memory appears to be similar clocked and sized. Therefore, the RTX2070 offers 2,304 shaders and 8 GB GDDR6 memory connected by a 256 bit interface (14 GHz, 448 GB/s).

A more power efficient "Max-Q" version is also available with further reduced clock rates.

In April 2020 Nvidia refreshed the RTX 2070 with new "Super" cards. In addition to the RTX 2070 Super Mobile with 2560 shaders, Nvidia also introduced a slightly higher clocked RTX 2070 for laptops (N18E-G1R-A1, TU106-735-A1 chip) with a 1,305 base and 1,485 MHz boost clock.

Features

NVIDIA manufacturers the TU106 chip on a 12 nm FinFET process and includes features like Deep Learning Super Sampling (DLSS) and Real-Time Ray Tracing (RTRT), which should combine to create more realistic lighting effects than older GPUs based on the company's Pascal architecture (if the games supports it). The RTX 2070 is also DisplayPort 1.4 ready, while there is also support for HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and H.265 video en/decoding (PlayReady 3.0).

Performance

The mobile RTX 2070 should perform a bit slower than the desktop RTX 2070 and therefore on par the old GTX 1080 for laptops. Therefore, it should be able to run all demanding games in 4k with high details. Raytracing features however may reduce framerates a lot.
