NVIDIA T500 Laptop GPU vs NVIDIA GeForce RTX 2070 Super Max-Q vs NVIDIA GeForce RTX 2080 Super Mobile

The Nvidia T500 Mobile (formerly known as Quadro T500) for laptops is a professional mobile graphics card that is based on the Turing architecture (TU117 chip). It is based on the consumer GeForce MX450 and features the same 896 cores and a 64 Bit memory bus. Currently it is available with 2 or 4 GB graphics RAM (GDDR5 or GDDR6). The TDP ranges between 18 - 25 Watt depending on the variant. As the MX450, the T500 also supports PCIe 4.0. The chip is manufactured in 12nm FinFET at TSMC. 

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 T500 does not feature raytracing and Tensor cores.

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).
