NVIDIA GeForce GTX 1660 Ti Mobile vs Intel UHD Graphics 24EUs (Alder Lake-N)

The Nvidia GeForce GTX 1660 Ti for laptops is a mobile graphics card that is based on the Turing architecture (TU116 chip). Compared to the faster RTX 2000 GPUs (e.g. RTX 2060), the 1660Ti integrates no Raytracing or Tensor cores. The performance is similar to the old GTX 1070 (laptop) but at a reduced TGP of 80 Watt (versus 115 Watt). Compared to the desktop GTX 1660 Ti, the clock speeds are reduced (3% lower base, 10% lower boost).

In April 2020 Nvidia refreshed the GTX 1660 Ti with the new codename N18E-G0-A1 with similar specs and pin compatible to the refreshed RTX chips (e.g., RTX 2070 Super Mobile).

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 up to 50% more instructions per clock and a 40% more power efficient usage compared to Pascal.

The power consumption of the 1660Ti for latops is specified at 80 Watt TGP (Total Graphics Power) by Nvidia and therefore 20 Watt higher than the efficient (and slower) Max-Q variant of the 1660 Ti. The TU116 chip is manufactured in 12nm FFN at TSMC.

The Intel UHD Graphics 24EUs (Xe-LP, Alder Lake-N, Gen 12.2) is a integrated graphics card in the mid range Alder Lake-N models like the Intel Processor N100. It is using the current Xe-LP architecture (Gen12) and was announced in late 2022. The GPU uses 24 of the 32 EUs (execution units) in the chip (192 of the 256 shader cores).

The performance is severely hindered by the single channel memory controller of Alder Lake-N, the low CPU performance and relatively low shader count. Therefore, only very low demanding games like Dota 2 in lowest settings can be played with the UHD Graphics GPU.

The whole SoC is manufactured in 10nm (Intel 7 process) at Intel.
