NVIDIA Quadro T1000 (Laptop) vs NVIDIA GeForce RTX 3070 Ti Laptop GPU

The Nvidia Quadro T1000 for laptops is a professional mobile graphics card that is based on the Turing architecture (TU117 chip). Compared to the consumer GTX 1650, the Quadro T1000 features less CUDA cores / shaders (768 versus 896). The Quadro T2000 uses the same TU117 chip, but features all 1024 cores (2x to the T1000) and is therefore significantly faster. 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 T1000 and T2000 don not feature raytracing and Tensor cores.

The Nvidia GeForce RTX 3070 Ti Laptop GPU (mobile, GN20-E6, Max-P, Max-Q) is a mobile graphics card for notebooks and the refresh of the RTX 3070. It was announced early 2021 at CES and is based on the same GA104 Ampere chip as the old RTX 3070 Laptop. Compared to the old card, the newer one offers 15% more shaders but less clock speed. It will still feature the 256 Bit memory bus and 8 GB GDDR6. The RTX 3070ti is available in different power variants ranging from 80 Watt TGP with a Boost clock of 1035 MHz up to 125 Watt models with a Boost clock of 1485 MHz. However, there are even some models with a maximum TGP of 150 Watt (e.g., Acer Nitro 5).

There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, Whispermode).

The performance depends on the TGP setting and cooling of the laptop. On average it should be somewhere between the old RTX 3070 Mobile and RTX 3080 Mobile (at similar TDP settings). Therefore, the card is best suited for QHD gaming in max details (for demanding games like Cyberpunk 2077). Less demanding games like the Farming Simulator 22 or older games should also run in 4K with max. detail settings.

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). The RTX 3070 Ti however won't use all ALUs on the chip. With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The RTX 3070 Ti mobile series uses 5,888 of the 6,144 cores. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA104 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip).
