NVIDIA GeForce GTX 1660 Ti Mobile vs NVIDIA GeForce RTX 2060 (Desktop) vs NVIDIA GeForce GTX 1650 Ti Max-Q

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 2060 for desktops is a fast mid range graphics card in the GeForce Turing line-up. It uses a TU106 chip with 1,920 shader, 45 ROPs, 120 TMUs, 240 KI-cores and a 192 Bit memory bus that connects 6 GB of GDDR6 (clocked at 7 GHz leading to 14 GHz effective and 336 GB/s).

 The mobile variant of the RTX 2060 bears the same name, but offers considerable lower clock speeds (see our RTX 2060 laptop page).

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 2060 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 average RTX 2060 should be on par with a Radeon RX Vega 64 and between the GeForce GTX 1070 and GTX 1080 / 1070 Ti. Therefore, the RTX 2060 is most suited for 1920x1080 to 2560x1440 in demanding games.

Power Requirements

NVIDIA specifies that the RTX 2060 should consume a maximum of 160 W and therefore clearly higher than the old GTX 1060 rated at 120 Watt.

The Nvidia GeForce GTX 1650 Ti Max-Q (N18P-G62) is a dedicated mid range graphics card for laptops based on the Turing architecture. The Max-Q variant is the power saving version of the mobile GTX 1650Ti with reduced clock speeds, performance and of course power consumption. It is using the same TU117 chip with 1,024 shaders. Therefore, it is intended for thin and light gaming laptops. Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 Ti integrates no Raytracing or Tensor cores.

There are two variants of the 1650Ti Max-Q, one with 35 Watt and 1035 - 1200 MHz and a faster 40 Watt version with a clock speed of 1200 - 1365 MHz. Both however are significantly lower clocked than the normal Max-P version with 50 / 55 Watt and 1350-1385 MHz. The memory is most likely clocked at 1250 MHz = 10,000 MHz effective (Gbps) in most laptops, although there might be versions with 1500 MHz = 12,000 Gbps.

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 50% more instructions per clock and a 40% more power efficient usage compared to Pascal.

Compared to the bigger Turing chips (like the TU116 of the GTX 1660 Ti and the RTX lineup), the TU117 does not include the new NVENC encoder but an older one similar to the one used in Pascal and Volta.

The power consumption of the 1650 Ti Max-Q laptops is specified at 35 Watt TGP (Total Graphics Power) by Nvidia and therefore 25 Watt lower than the mobile GTX 1650 Ti in the same package (other variants can reach up to 80 Watt).
