Intel UHD Graphics 600 vs NVIDIA GeForce RTX 2080 Mobile vs NVIDIA GeForce RTX 2060 Mobile

The NVIDIA GeForce RTX 2080 for laptops is the fastest mobile graphics card for notebooks in early 2019. It is based on the desktop RTX 2080 but with reduced core speeds (-7% Boost, -9% Base). The memory appears to be similar clocked and sized. Therefore, the RTX2080 offers 2,944 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 planned with further reduced clock rates.

Features

NVIDIA manufacturers 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 mobile RTX 2080 should perform a bit slower than the desktop RTX 2080 and therefore definitely faster than the old GTX 1080 for laptops. Therefore, it should be able to run all demanding games in 4k with maximum details. Raytracing features however may reduce framerates a lot.

The power consumption of the card was reduced from 215 Watt for the desktop RTX 2080 to 150 Watt. However, it is still only suited for thick and heavy gaming laptops. For thinner and lighter designs, the Max-Q variant of the RTX 2080 is intended that can be configured at 80 or 90 Watt (at much lower clock speeds).

The NVIDIA GeForce RTX 2060 for laptops is a fast mid-range gaming graphics card for laptops. It is based on the desktop RTX 2060 chip but at reduced GPU clock rates (-30%) and reduces power consumption (80 - 90 Watt TGP versus 160 Watt for the desktop version).

In 2020 Nvidia also released a refreshed version with the same name. It is based on the TU106B chip and offers new voltage regulators and controllers. Furthermore, the maximum TGP was increased to 115 Watt and therefore the GPU can clock higher (1005 - 1560 MHz). The memory speed however was decreased to 11 Gbps leading to a slightly better overall performance compared to the old version.

NVIDIA manufacturers the Turing 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 2060 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).

The gaming performance of the mobile RTX 2060 is similar to an old Nvidia GeForce GTX 1070 (Desktop) and clearly behind the desktop RTX 2060. The mobile GTX 1660 Ti is only a few percent behind in our gaming benhcmarks, but offers no raytracing features built in the GPU. For demanding games of 2019, the RTX 2060 is most suited for full HD (1080p) and high / ultra settings. However, there is not much headroom to activate the taxing raytracing features in most games.

The power consumption is rated at 80 - 90 Watt TGP by Nvidia and therefore similar to the Max-Q variants of the RTX 2070 and RTX 2080. In our real world laptop-tests the power draw of the whole systems running The Witcher 3 shows that the RTX 2060 slots in slightly below the Max-Q Variants and slightly above the GTX 1660 Ti mobile (as expected).
