GTX 1660 Ti vs GTX 1070 vs GTX 1060 vs RX 590 Comparison

GeForce GTX 1660 Ti is the first GTX 16 series graphics card from Nvidia. This is a completely new series from Nvidia, which is mainly targeted towards mainstream and budget gamers. GTX 1660 Ti is a mid-range card that is said to be the replacement of GTX 1060, but in reality, it is much more powerful and is a tough competitor to GTX 1070 and Radeon RX 590. GeForce GTX 1660 Ti is based on the Turing GPU architecture, but it does lack some of the features present in RTX Turing GPUs.

Here is a complete comparison between GTX 1660 Ti, GTX 1070, GTX 1060 and RX 590 graphics cards based on their specifications, performance, pricing, power consumption and features.

GPU Architecture

GTX 1060 and GTX 1070 are built on Pascal GPU architecture with 14nm fabrication process while GTX 1660 Ti is built on Turing GPU architecture having 12nm manufacturing process. On the other hand, Radeon RX 590 is an AMD graphics card that is built on Polaris GPU architecture with 12nm process.

GTX 1060 comes with 1280 CUDA Cores; GTX 1070 with 1920 CUDA Cores and GTX 1660 Ti has 1536 CUDA Cores. On the other hand, Radeon RX 590 has got 2304 Stream Processors, which cannot be compared with CUDA Cores because of the difference of architecture and technology between Nvidia and AMD graphics cards.

Memory [VRAM]

GTX 1060 and GTX 1660 Ti comes with 6GB video memory having 192-bit interface, but they differ in memory type and speed. The former one comes with GDDR5 / GDDR5X memory and the later one has got GDDR6 memory, which is must faster than GDDR5 and GDDR5X memory types. On the other hand, both GTX 1070 and Radeon RX 590 comes with 8GB GDDR5 memory having 256-bit memory interface. So, here the card that has fastest memory is GTX 1660 Ti and the one with slowest is GTX 1060. GTX 1660 Ti does have 2GB less memory compared to GTX 1070 and RX 590, but its significantly higher memory speed and bandwidth makes up for it.

Features

All these four graphics cards support DirectX 12, OpenGL 4.5, Vulkan, OpenCL and are VR ready. Also, all of them support variable refresh rate technologies to prevent screen tearing in games. Radeon RX 590 supports FreeSync, while the other Nvidia cards include support for both FreeSync and G-Sync. The cards that support multi-GPU technology are GTX 1070 and RX 590. GTX 1070 supports SLI through HB SLI bridge, while RX 590 support CrossFire or mGPU without need of any bridge or connector. One other thing that is common across all these cards is that all them support hardware based H265/HEVC and 4K H264 Encoding and Decoding for Video Editing and Rendering.

Features that are only present in GTX 1660 Ti here are Dedicated FP16 Cores, Adaptive Shading / Motion Adaptive Shading (MAS) / Content Adaptive Shading (CAS) and a new NVEC Encoder that delivers 15% improved efficiency over prior-generation nvidia graphics cards and is optimized for Open Broadcaster Software (OBS).

gtx-1660-ti-benchmarks-1440p

From the above gaming benchmarks, we can clearly see that GTX 1660 Ti is the fastest card here in most of the games. It is as fast as GTX 1070 and sometimes better, and around 40% faster than GTX 1060 in almost games. Also, it beats RX 590 clearly and is around 20% faster (or slightly more) than it. So, the winner here is clearly GTX 1660 Ti when it comes to gaming at 1080p and 1440p.

Power Consumption

When it comes to power consumption then the winners are GTX 1060 and the new GTX 1660 Ti, whereas the card that consumes the most power is the RX 590, which is no surprise at all. Also, you will need a good 450W to 500W PSU for these mid-range graphics cards.

Final Thoughts

Nvidia has finally hit the sweet spot with GTX 1660 Ti after that humongous disaster with RTX 20 series cards. The card is basically a GTX 1070 replacement, but with much lower price tag and lower power consumption. There is absolutely no point in comparing GTX 1660 Ti with GTX 1060 and even RX 590, because it crushes them easily in every benchmark. The only thing in which GTX 1070 and RX 590 has an advantage over GTX 1660 Ti is the greater amount video memory i.e. 8GB. However, for 1080p and 1440p gaming, 6GB is enough for most of the current AAA games, and the faster GDDR6 memory in GTX 1660 Ti makes up for lack of 2GB VRAM it has in this case. So, in my opinion GTX 1660 Ti is really a great product at merely $279, and is clearly the winner among all these cards here.
