NVIDIA GeForce RTX 2080 Mobile vs NVIDIA GeForce RTX 2080 Super 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 2080 Super with Max-Q design is the power saving variant of the mobile GeForce RTX 2080 Super with reduced clock speeds, performance and of course power consumption. It is intended for thin gaming laptops and based on the same TU104 chip with 3,072 shaders, 8 GB GDDR6 memory and a 256 Bit memory bus.

Currently it looks like there are three variants with a TGP of 80, 85 and 90 Watt. The clock speed ranges from 735 - 975 MHz for the base clock speed and 1080 - 1230 for the boost.

With the refresh, Nvidia also reworked the Max-Q technologies for more efficiency. Low Voltage GDDR6 (lower clocked but more headroom for the GPU) and improved regulator efficiency should improve the performance per Watt. Two new optional features can also be implemented by the OEM. Max-Q Dynamic Boost is able to shift power from the CPU to the GPU on a per frame basis to increase overall performance. Furthermore, the laptop manufacturer can also implement Advanced Optimus with a dynamic display switch (hardware) to enable Optimus, G-SYNC and high refresh rate displays (up to 4K 120 Hz).

Performance

Due to the lower clock rates, the Max-Q variant is clearly slower than the mobile RTX 2080 Super. In our benchmarks with the first devices, the performance is very similar to the old RTX 2080 Max-Q and only on a level with the non Max-Q RTX 2070. Therefore, the performance is ideal for 1440p gaming at max details for demanding games like Red Dead Redemption 2, Control or Borderlands 3. Less demanding games like F1 2019 can be played in 4k with maximum settings. Detailed gaming benchmarks can be found at the end of this page.

The power consumption of the card is between 80 - 90 Watt TGP and therefore significantly lower than the RTX 2080 Super Mobile (150 - 200 Watt).
