NVIDIA GeForce GTX 1070 (Desktop) vs AMD Radeon RX 580 (Desktop) vs NVIDIA GeForce GTX 1660 (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.

AMD Radeon RX 580 (Desktop)

NVIDIA GeForce GTX 1660 (Desktop)

The Nvidia GeForce GTX 1660 is a mid-tier, Turing-based, desktop GPU. The GTX 1660 relies on the TU116 chip with 1,408 shader units, 48 ROPs, 88 TMUs and a 192-bit-wide memory bus (clocked at 2 GHz = 8 GHz effectively 12 GHz, bandwidth: up to 192.1 GB/s).

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 is slightly faster than the old GeForce GTX 1060, but clearly slower than the old GeForce GTX 1070 (and GTX 1660 Ti). Therefore, the GTX1660 is well suited for demanding games of 2019 in 1080p and high - max details (see gaming benchmarks below).

The energy consumption of the GeForce GTX 1660 amounts to 120 watts (like the 1660 Ti or GTX 1060).
