NVIDIA GeForce GTX 1660 Ti (Desktop) vs NVIDIA GeForce RTX 4070 vs NVIDIA GeForce RTX 4080 Super

NVIDIA GeForce GTX 1660 Ti (Desktop)

The Nvidia GeForce GTX 1660 Ti is a powerful, mid-tier, Turing-based, desktop GPU. The GTX 1660 Ti relies on the TU116 chip with 1536 shader units, 48 ROPs, 96 TMUs and a 192-bit-wide memory bus (clocked at 6 GHz, effectively 12 GHz, bandwidth: up to 288 GB/s). The notebook version of the GTX 1660 Ti  is 10 to 20 % slower due to a lower TDP.

The TU116 chip and other Turing-based GPUs are produced using the 12-nm manufacturing process. However, the GeForce GTX 1660 Ti does not offer the latest features such as DLSS (Deep Learning Super Sampling) and Real Time Ray Tracing. Nevertheless, there are some architectural improvements when it comes to floating point and integer performance. These operations can now be carried out simultaneously. Other notable features include Adaptive Shading, unified cache, DisplayPort 1.4, HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) as well as H.265 encoding and decoding (PlayReady 3.0).

At Full HD resolution, the GeForce GTX 1660 Ti performs somewhat worse than the GeForce GTX 1070, but significantly better than the GeForce GTX 1060. Therefore, it is best-suited for Full HD gaming. However, it can run less demanding titles in 1440p.

The energy consumption of the GeForce GTX 1660 Ti amounts to 120 watts. The older GeForce GTX 1060 also has a TDP of 120 watts.

NVIDIA GeForce RTX 4070

The Nvidia GeForce RTX 4070 is a high-end desktop graphics card based on the AD104 chip using the Ada Lovelace architecture. The 4070 offers 5,888 cores and 12 GB GDDR6X graphics memory with a 192 bit memory bus and clocked at 21 Gbits. The card offers a good raytracing performance thanks to the 46 dedicated raytracing cores. For AI calculations (and DLSS 3 in games), the RTX 4070 has 184 Tensor cores.

The gaming performance is well suited for 2k/QHD gaming in most demanding games, and should be able to handle 4k gaming for lesser demanding games (or with reduced settings / DLSS activated). The raw gaming performance is comparable to an older RTX 3080 or a AMD Radeon 6800 XT. Compared to the similar named mobile GeForce RTX 4070 Laptop GPU, the desktop variant is much faster.

The AD104 chip is manufactured in the modern 5nm process at TSMC (4N with EUV) and specified with a TGP (Total Graphics Power) of 200 Watt (compared to the 450 Watt of the RTX 4090).

NVIDIA GeForce RTX 4080 Super

The Nvidia GeForce RTX 4080 Super is a high-end desktop graphics card based on the Ada Lovelace architecture. It uses the AD103 chip in full configuration with 10,240 cores and 16 GB GDDR6X graphics memory (256-bit bus with 23 Gbits).

The ray tracing performance is outstanding thanks to 76 dedicated cores and the 320 Tensor cores can be used for DLSS 3.

The gaming performance without DLSS is ideal for 4k with around 60fps and 2k with higher frame rates in demanding games without ray tracing effects (e.g. F1 22 or Cyberpunk 2077). With ray tracing, the use of DLSS is recommended. Compared to the competition, the performance without DLSS and ray tracing is slightly better than the significantly cheaper AMD Radeon RX 7900 XT.

The currently available RTX 4080 cards are very large (2.5 or 3 slots) and use the new 12VHPWR connector (which has caused some problems with adapters).

The AD103 chip is produced at TSMC in 5nm (4N with EUV) and is specified with a TGP (Total Graphics Power) of 320 watts (Nvidia recommends at least a 750 watt power supply).
