NVIDIA GeForce RTX 2080 Super Mobile vs NVIDIA GeForce RTX 2060 Max-Q vs NVIDIA GeForce RTX 2070 Super Mobile

The NVIDIA GeForce RTX 2080 Super Mobile is the fastest mobile graphics card for laptops in early 2020. It is based on the desktop RTX 2080 Super, but most likely with reduced core speeds. According to early information it will be only slightly faster than a RTX 2080 with the same TGP setting (max. 200 Watt).

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 Super 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 Super Mobile should perform only slightly better than the old mobile RTX 2080. 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 can be set with 150 or 200 Watt TGP according to early information. Therefore, the normal Max-P variant is only suited for thick and heavy gaming laptops. A Max-Q variant for thin and light laptops is also planned (most likely at 80 - 90 Watt as the RTX 2080 Max-Q with similar performance).

The NVIDIA GeForce RTX 2060 with Max-Q design is the power saving variant of the mobile GeForce RTX 2060. Therefore it is a high end gaming graphics card for thin laptops. It is based on the same chip as the RTX 2060 but with reduced clock speeds and a lower power consumption. It was released in 2020 with the Zephyrus G14 gaming laptop.

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).

The clock is not the only difference compared to the regular GTX 2060 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).

The performance should be only slightly below the normal RTX 2060 due to the decreased clock rates. It should be most suited for 1080p gaming at maximum detail level. Raytracing features however may reduce framerates a lot, so using raytracing will be limited to some games.

The chip is specified at a TGP of around 65 Watt and therefore clearly lower than the 80 - 90 Watt of the regular RTX 2060 Mobile.

The NVIDIA GeForce RTX 2070 Super Mobile is a high end gaming graphics cards for laptops. It is the 2020 refresh of the GeForce RTX 2070 Mobile and may now also use the TU104 chip with more shaders (as the desktop RTX 2070 Super did). The older mobile RTX 2070 uses the TU106 chip with 2,304 shaders and should be slightly slower than the new Super model.
