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).
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).
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.
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.
