NVIDIA GeForce RTX 2080 Max-Q vs NVIDIA GeForce GTX 1660 (Desktop) vs NVIDIA GeForce RTX 2070 Mobile

The NVIDIA GeForce RTX 2080 with Max-Q design is the power saving variant of the mobile RTX 2080 with reduced clock speeds and power consumption. Therefore, it is suitable for thin gaming laptops. It is based on the same TU104 chip is the desktop and mobile variant and offers 2,944 shaders and 8 GB GDDR6 memory connected by a 256 bit interface (12 GHz).

Currently it looks like there will be two variants, a low power 80 Watt variant with 735 - 1095 MHz core clock and a faster 90 Watt variant with 990 - 1230 MHz core clock).

The clock is not the only difference compared to the regular RTX 2080 though. The drivers for the Max-Q version were optimized for efficiency (and not performance; only for Max-Q models), there are optimized voltage converters for 1V operation, high-end cooling methods, and a 40 dB limit for the fan noise (with clock adjustments to ensure this at all times).

Features

NVIDIA manufactures the TU104 chip on a 12 nm FinFET process and includes features like Deep Learning Super Sampling (DLSS) and Real-Time Ray Tracing (RTRT), which should combine to create more realistic lighting effects than older GPUs based on the company's Pascal architecture (if the games supports it). The RTX 2080 is also DisplayPort 1.4 ready, while there is also support for HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and H.265 video en/decoding (PlayReady 3.0).

Performance

The RTX 2080 Max-Q should be slightly faster than a regular mobile RTX 2070 and therefore a high end gaming graphics card. It should be able to run all demanding games in 4k with maximum details. Raytracing features however may reduce framerates a lot.

The NVIDIA GeForce RTX 2070 for laptops is the second fastest mobile graphics card for notebooks in early 2019. It is based on the desktop RTX 2070 but with reduced core speeds (-11% Boost, -14% Base). The memory appears to be similar clocked and sized. Therefore, the RTX2070 offers 2,304 shaders and 8 GB GDDR6 memory connected by a 256 bit interface (14 GHz, 448 GB/s).

A more power efficient "Max-Q" version is also available with further reduced clock rates.

In April 2020 Nvidia refreshed the RTX 2070 with new "Super" cards. In addition to the RTX 2070 Super Mobile with 2560 shaders, Nvidia also introduced a slightly higher clocked RTX 2070 for laptops (N18E-G1R-A1, TU106-735-A1 chip) with a 1,305 base and 1,485 MHz boost clock.

Features

NVIDIA manufacturers the TU106 chip on a 12 nm FinFET process and includes features like Deep Learning Super Sampling (DLSS) and Real-Time Ray Tracing (RTRT), which should combine to create more realistic lighting effects than older GPUs based on the company's Pascal architecture (if the games supports it). The RTX 2070 is also DisplayPort 1.4 ready, while there is also support for HDMI 2.0b, HDR, Simultaneous Multi-Projection (SMP) and H.265 video en/decoding (PlayReady 3.0).

Performance

The mobile RTX 2070 should perform a bit slower than the desktop RTX 2070 and therefore on par the old GTX 1080 for laptops. Therefore, it should be able to run all demanding games in 4k with high details. Raytracing features however may reduce framerates a lot.
