NVIDIA GeForce RTX 2080 Mobile vs NVIDIA GeForce RTX 2060 (Desktop) vs NVIDIA GeForce RTX 2080 Max-Q

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 desktops is a fast mid range graphics card in the GeForce Turing line-up. It uses a TU106 chip with 1,920 shader, 45 ROPs, 120 TMUs, 240 KI-cores and a 192 Bit memory bus that connects 6 GB of GDDR6 (clocked at 7 GHz leading to 14 GHz effective and 336 GB/s).

 The mobile variant of the RTX 2060 bears the same name, but offers considerable lower clock speeds (see our RTX 2060 laptop page).

Performance

The average RTX 2060 should be on par with a Radeon RX Vega 64 and between the GeForce GTX 1070 and GTX 1080 / 1070 Ti. Therefore, the RTX 2060 is most suited for 1920x1080 to 2560x1440 in demanding games.

Power Requirements

NVIDIA specifies that the RTX 2060 should consume a maximum of 160 W and therefore clearly higher than the old GTX 1060 rated at 120 Watt.

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).

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.
