NVIDIA GeForce RTX 2080 Super Mobile vs NVIDIA T600 Laptop GPU 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 T600 Laptop GPU (or Quadro T600 for laptops) is a professional mobile graphics card that is based on the Turing architecture (TU117 chip). It is similar to the consumer GTX 1650 with 896 CUDA cores and a 128 Bit memory bus for GDDR6 graphics memory (10 Gbits). The chip is manufactured in 12nm FinFET at TSMC. The T600 was introduced as a refresh together with the T1200 and should be slightly slower than the older Quadro T1000 (2.6 versus 2.5 TFLOPS peak SP performance).

The Turing generation did not only introduce raytracing for the RTX cards, but also optimized the architecture of the cores and caches. According to Nvidia the CUDA cores offer now a concurrent execution of floating point and integer operations for increased performance in compute-heavy workloads of modern games.

Furthermore, the caches were reworked (new unified memory architecture with twice the cache compared to Pascal). This leads to up to 50% more instructions per clock and a 40% more power efficient usage compared to Pascal. In contrary to the faster Quadro RTX cards, the T600 do not feature raytracing and Tensor cores.

Currently Nvidia only specifies the TDP of 25 Watt (the older T1000 had a TGP of 40-50 Watt). Therefore, the T600 should be well suited for thin and light laptops.

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.
