The Nvidia GeForce GTX 1650 Ti Mobile is a dedicated mid range graphics card for laptops based on the Turing architecture. It uses the same TU117 chip as the desktop version but for the mobile GPU all 1024 shaders are enabled. Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 Ti integrates no Raytracing or Tensor cores.
There are two packages of the GTX 1650Ti, the GB4D-128 with a 128 Bit memory bus and a TGP of 50 Watt and the GB4B-256 with a 256 Bit memory bus and a TGP of 55 Watt (compatible with the faster RTX cards). The clock rates seem to be identical for both versions, therefore, the 256 Bit version should be faster.
The Turing generation did not only introduce raytracing for the RTX cards, but also optimized the architecture of the cores and caches. According to Nvidia the CUDA cores offer now a concurrent execution of floating point and integer operations for increased performance in compute-heavy workloads of modern games. Furthermore, the caches were reworked (new unified memory architecture with twice the cache compared to Pascal). This leads to 50% more instructions per clock and a 40% more power efficient usage compared to Pascal.
Compared to the bigger Turing chips (like the TU116 of the GTX 1660 Ti and the RTX lineup), the TU117 does not include the new NVENC encoder but an older one similar to the one used in Pascal and Volta.
The power consumption of the 1650 Ti for laptops is specified at 50 - 80 Watt TGP (Total Graphics Power) by Nvidia and therefore 5 - 25 Watt higher than the GTX 1650. The power efficient Max-Q variant of the GTX 1650 Ti is rated at 35 Watt TGP.
The AMD Radeon RX Vega 8 is an integrated GPU for notebooks. It is used for the Ryzen 5 APUs, which were launched in the end of 2017. The GPU is based on the Vega architecture (5th generation GCN) and has 8 CUs (= 512 of the 704 shaders) clocked at up to 1100 MHz (Ryzen 5 2500U). 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.
AMD's reference design GPU is sitting between the GeForce 940MX / Radeon Pro 450 and GeForce MX150 / Radeon Pro 555. It can handle smooth gameplay in simple titles like League of Legends (med), Dota 2 (low), Overwatch (low), CS:GO (med), and Quake Champions (high) in 720p up to 1080p according to AMD.
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.
The Nvidia GeForce GTX 1650 for laptops is a mobile graphics card that is based on the Turing architecture (TU117 chip). Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1650 integrates no Raytracing or Tensor cores. The performance should be slightly faster than the old GeForce GTX 1050 Ti. Compared to the desktop version, the mobile GTX1650 can use all 1024 shaders of the TU117 chip, but there are also versions with 896 shaders.
Starting March 2020, the GTX 1650 Mobile is also available with fast 12 Gbits GDDR6 graphics memory (N18P-G61, 896 shaders) as a refresh.

The power consumption of the 1650 for laptops is specified at 50 Watt TGP (Total Graphics Power) by Nvidia and therefore 15 Watt higher than the efficient (and slower) Max-Q variant of the 1650. The TU117 chip is manufactured in 12nm FFN at TSMC.
