NVIDIA GeForce GTX 1080 SLI (Laptop) vs NVIDIA GeForce GTX 1650 Super (Desktop) vs NVIDIA GeForce GTX 1070 Ti (Desktop)

NVIDIA GeForce GTX 1080 SLI (Laptop)

The Nvidia GeForce GTX 1080 SLI for laptops is a combination of two GTX 1080 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1080 to up to 90% faster performance. Sometimes, the combination may also suffer from micro-stuttering. The technical details of the card are identical to a single GTX 1080 (see for more information) and the power consumption is doubled. Therefore, the 1080 SLI combination is only found in huge clunky laptops.

NVIDIA GeForce GTX 1650 Super (Desktop)

The Nvidia GeForce GTX 1650 Super for desktops is an entry-level gaming graphics card based on the Turing architecture. The chip, which has been named TU116, was introduced in November 2019. The GTX 1650 series does not offer ray tracing and tensor cores, unlike the more powerful RTX 2000 cards (e.g. RTX 2060). Performance is slightly better than with the GeForce GTX 1650 and comparable with the AMD Radeon RX 5500 XT.

There have also been significant improvements in the Turing architecture in terms of the CUDA cores. Float and INT operations can now be executed simultaneously, the cache has been unified and improved, and Adaptive Shading has been introduced. As a result, Nvidia speaks of an up to 50% higher performance per core compared to Pascal.

The new entry-level card benefits from the advantages of the TU116 chip, since the newer NVENC video encoding delivers more performance compared to Pascal.

Nvidia specifies a power consumption of 100 watts TGP (Total Graphics Power) for the graphics card. The TU11 chip is manufactured by TSMC in a 12 nm FFN process.

NVIDIA GeForce GTX 1070 Ti (Desktop)

The Nvidia GeForce GTX 1070 Ti is the second fastest Pascal based graphics card in November 2017. It is a high-end desktop graphics card based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. Compared to the GTX 1080, it uses the more available GDDR5 graphics memory, and compared to the GTX 1070 it offers more shaders (2432 versus 1920). More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

The performance of the GTX 1070 Ti was in our tests right between the GTX 1070 and GTX 1080. However, the powerefficiency was worse than the GTX 1070 and near the GTX 1080. Nvidia also specifies the 1070 Ti and 1080 at 180W.
