AMD Radeon RX Vega 6 (Ryzen 2000/3000) vs NVIDIA GeForce GTX 1660 Ti Mobile vs NVIDIA GeForce GTX 1660 (Desktop)

AMD Radeon RX Vega 6 (Ryzen 2000/3000)

The AMD Radeon RX Vega 6 is an integrated GPU for notebooks. It is used for the Ryzen 3 APUs, which were launched in early 2018. The GPU is based on the Vega architecture (5th generation GCN) and has 6 CUs (= 384 of the 704 shaders) clocked at up to 1100 MHz. The performance depends on the configured TDP (12-25 W at launch), the clocks, the cooling, and the memory configuration). The GPU should benefit from fast dual-channel DDR4-2400 RAM (contrary to DDR4-2133 single-channel, which is also possible).

The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.

Currently we estimate a performance around a Intel UHD Graphics 630. Therefore, only lower demanding games of 2016 should run in low detail settings fluently.

Thanks to the 14nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks.

NVIDIA GeForce GTX 1660 Ti Mobile

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).
