NVIDIA GeForce RTX 2080 Mobile vs NVIDIA GeForce RTX 2070 Super (Desktop)

The NVIDIA GeForce RTX 2080 for laptops is the fastest mobile graphics card for notebooks in early 2019. It is based on the desktop RTX 2080 but with reduced core speeds (-7% Boost, -9% Base). The memory appears to be similar clocked and sized. Therefore, the RTX2080 offers 2,944 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 planned with further reduced clock rates.

Features

NVIDIA manufacturers the TU104 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 2080 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 2080 should perform a bit slower than the desktop RTX 2080 and therefore definitely faster than the old GTX 1080 for laptops. Therefore, it should be able to run all demanding games in 4k with maximum details. Raytracing features however may reduce framerates a lot.

The power consumption of the card was reduced from 215 Watt for the desktop RTX 2080 to 150 Watt. However, it is still only suited for thick and heavy gaming laptops. For thinner and lighter designs, the Max-Q variant of the RTX 2080 is intended that can be configured at 80 or 90 Watt (at much lower clock speeds).

The NVIDIA GeForce RTX 2070 Super (RTX 2070S) is a high-end desktop graphics card and refresh of the 2018 RTX 2070. The card is now behind the RTX 2080 Ti and RTX 2080 Super (upcoming) as the third-fastest graphics card in the Nvidia lineup of consumer cards. It uses the big TU104 chip instead of the TU106 of the RTX 2070 and offers more cores (2,560 versus 2,304).

Performance

The performance of the RTX 2070S is slightly better than the old GeForce GTX 1080 Ti. With the new ray-tracing and tensor cores, the RTX 2070S is clearly the better choice. The RTX 2070 Super is positioned in the high-end segment and therefore most current games should run fluently in 4k and high detail settings (but without ray tracing). Compared to AMD offerings, the RTX 2070 Super is aimed against the AMD Radeon RX 5700 XT (Navi).

Power Requirements

NVIDIA estimates that the RTX 2070S should consume a maximum of 215 W (RTX 2070 - 175 Watt). In our gaming tests, the RTX 2070 Super was more power-efficient than the old GeForce GTX 1080 Ti (339 versus 296 Watt for the test system running The Witcher 3).
