AMD Radeon 780M vs NVIDIA GeForce GTX 1650 (Desktop) vs NVIDIA GeForce GTX 1660 Ti (Desktop)

AMD Radeon 780M

The AMD Radeon 780M is an integrated GPU in the Ryzen 7040 series for laptops (Phoenix, e.g. Ryzen 9 7940HS). The iGPU is based on the new RDNA3 architecture and has 12 CUs (= 768 shaders) clocked at up to 3 GHz (depending on the CPU model). As the predecessor Radeon 680M, the 780M supports hardware raytracing, although the performance is too slow to use it in current games.

Thanks to the new architecture and higher clock speeds, the Radeon 780M should be clearly faster then the old Radeon 680M. This means most demanding games should be playable in minimum graphics settings (like Cyberpunk 2077) and less demanding games like Fifa 23 can be played in higher settings and resolutions (1080p). In early 2023, the Radeon 780M is the fastest iGPU on the market.

Thanks to the modern 4nm process and clever power-saving features, the power consumption is comparatively low (according to AMD). The whole chip of the first two models can be configured between 15 - 54 Watt TDP.

NVIDIA GeForce GTX 1650 (Desktop)

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.
