NVIDIA GeForce GTX 1070 (Desktop) vs NVIDIA GeForce GTX 1660 Ti (Desktop) vs NVIDIA GeForce GT 1030 (Desktop)

NVIDIA GeForce GTX 1070 (Desktop)

The Nvidia GeForce GTX 1070 is the second fastest Pascal based graphics card in mid May 2016. It is a high-end desktop graphics card. The mobile pendant is also called GeForce GTX 1070, but features more shaders and a lower core clock (see this page for details on the laptop version of the GTX 1070). Both cards are based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

Compared to the GTX1080, the GTX1070 features less CUDA cores (1920 versus 2560) that are clocked a bit lower (maximum Boost 1683 versus 1733). Instead of the new GDDR5X, the GTX 1070 uses slower GDDR5 graphics memory - but still 8 GB. The TDP is also reduced from 180 Watt to 150 Watt.

The performance of the GTX 1070 is between the old GTX 980 Ti and the GTX 1080. Therefore, gaming in 4k at high details is possible with the card and also VR gaming is possible.

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 GT 1030 (Desktop)

The Nvidia GeForce GT 1030 (sometime GTX 1030 called) is an entry level dedicated graphics card for desktops. It is based on the GP108 chip using the Pascal architecture in 14nm FinFET. It features three streaming multiprocessors (SMs) and therefore 384 shader cores, 24 texture units and 16 ROPs. The 2 GB GDDR5 memory are connected with two 32 Bit memory controller (48 GBit/s). The shaders are identical to other Pascal cards like the GTX 1050 and therefore also the support for DirectX 12 FL 12_1.

The performance is slightly below the Radeon RX 550 from AMD and therefore only suited for low to medium detail settings of modern games like Battlefield 1.

The TDP of the GT1030 is specified as 30 Watt.
