NVIDIA GeForce GTX 1660 Ti Mobile vs NVIDIA GeForce RTX 2070 Super (Desktop) vs NVIDIA GeForce GTX 1660 (Desktop)

The Nvidia GeForce GTX 1660 Ti for laptops is a mobile graphics card that is based on the Turing architecture (TU116 chip). Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1660Ti integrates no Raytracing or Tensor cores. The performance is similar to the old GTX 1070 (laptop) but at a reduced TGP of 80 Watt (versus 115 Watt). Compared to the desktop GTX 1660 Ti, the clock speeds are reduced (3% lower base, 10% lower boost).

In April 2020 Nvidia refreshed the GTX 1660 Ti with the new codename N18E-G0-A1 with similar specs and pin compatible to the refreshed RTX chips (e.g., RTX 2070 Super Mobile).

The Turing generation did not only introduce raytracing for the RTX cards, but also optimized the architecture of the cores and caches. According to Nvidia the CUDA cores offer now a concurrent execution of floating point and integer operations for increased performance in compute-heavy workloads of modern games. Furthermore, the caches were reworked (new unified memory architecture with twice the cache compared to Pascal). This leads to up to 50% more instructions per clock and a 40% more power efficient usage compared to Pascal.

The power consumption of the 1660Ti for latops is specified at 80 Watt TGP (Total Graphics Power) by Nvidia and therefore 20 Watt higher than the efficient (and slower) Max-Q variant of the 1660 Ti. The TU116 chip is manufactured in 12nm FFN at TSMC.

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).

Features

NVIDIA manufactures 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 can (if the games supports it). The RTX 2070S is 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 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).
