NVIDIA GeForce RTX 2080 Mobile vs NVIDIA GeForce RTX 3060 vs NVIDIA GeForce RTX 2080 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 2080 Super or 2080S sits behind the GeForce RTX 2080 Ti as the second fastest desktop GPU in NVIDIA's current Turing line-up (mid 2019). It is the refresh of the one year old RTX 2080 (Desktop) with slightly higher performance. The GPU offers 3,072 cores (up from 2,944) and is based on the TU104 chip. The VRAM is still 8 GB of GDDR6 but now higher clocked at 15.5 GHz (496 GB/s vs. 14 GHz and 448 GB/s).

Performance

The RTX 2080 Super slightly outperforms the older Nvidia Titan XP and of course the RTX 2080 which it succeeds. Therefore, the RTX2080S is located in the absolute high end and well suited for 4k gaming with high to maximum detail settings (depending on the game). Using raytracing features, will reduce the playable resolution however.

Power Requirements

NVIDIA estimates that the RTX 2080 Super should consume a maximum of 250 W, which is 35 W higher than the company rates its GeForce GTX 2080.
