NVIDIA GeForce GTX 1650 Ti Mobile vs NVIDIA GeForce RTX 2070 Super (Desktop) vs NVIDIA GeForce GTX 1650 Mobile

The Nvidia GeForce GTX 1650 Ti Mobile is a dedicated mid range graphics card for laptops based on the Turing architecture. It uses the same TU117 chip as the desktop version but for the mobile GPU all 1024 shaders are enabled. Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 Ti integrates no Raytracing or Tensor cores. 

There are two packages of the GTX 1650Ti, the GB4D-128 with a 128 Bit memory bus and a TGP of 50 Watt and the GB4B-256 with a 256 Bit memory bus and a TGP of 55 Watt (compatible with the faster RTX cards). The clock rates seem to be identical for both versions, therefore, the 256 Bit version should be faster.

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 for laptops is specified at 50 - 80 Watt TGP (Total Graphics Power) by Nvidia and therefore 5 - 25 Watt higher than the GTX 1650. The power efficient Max-Q variant of the GTX 1650 Ti is rated at 35 Watt TGP.

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).

The Nvidia GeForce GTX 1650 for laptops is a mobile graphics card that is based on the Turing architecture (TU117 chip). Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 integrates no Raytracing or Tensor cores. The performance should be slightly faster than the old GeForce GTX 1050 Ti. Compared to the desktop version, the mobile GTX1650 can use all 1024 shaders of the TU117 chip, but there are also versions with 896 shaders.

Starting March 2020, the GTX 1650 Mobile is also available with fast 12 Gbits GDDR6 graphics memory (N18P-G61, 896 shaders) as a refresh.

The power consumption of the 1650 for laptops is specified at 50 Watt TGP (Total Graphics Power) by Nvidia and therefore 15 Watt higher than the efficient (and slower) Max-Q variant of the 1650. The TU117 chip is manufactured in 12nm FFN at TSMC.
