NVIDIA GeForce RTX 3080 12 GB vs NVIDIA GeForce RTX 3070 Ti Laptop GPU vs NVIDIA GeForce RTX 3050 Ti Laptop GPU

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).

The Nvidia GeForce RTX 3050 Ti Laptop GPU (for laptops, NVIDIA_DEV.2583, GN20-P1) is a faster variant of the RTX 3050 mobile card and based on the GA107 Ampere chip. The chip offers 2560 CUDA, 20 Ray Tracing and 80 Tensor cores. The clock rate depends on the used TGP-version (from 35 - 80 Watt).

The performance (of the high TGP variants) should be similar to the old RTX 2060 and therefore most suited for 1080p gaming with high detail settings. The performance is not sufficient to enable Raytracing in most games, but the Tensor cores can be used for DLSS in some games (and get a performance boost with a slight quality reduction). Beware, that the low TGP variants will offer a significantly lower performance.

The GA107 chip offers 3,072 FP32 ALUs of which half can also execute INT32 instructions (i.e. 1,536 INT32 ALUs). The RTX 3050 Ti however maybe 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 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).
