AMD Radeon RX 6550M vs NVIDIA GeForce RTX 3080 Ti Laptop GPU vs NVIDIA GeForce RTX 3060 Max-Q

The Nvidia GeForce RTX 3080 Ti Laptop GPU or 3080 Ti Mobile (for laptops, GN20-E8) is the fastest graphics card for notebooks in early 2022. It is based on the GA103S Ampere chip and offers 7,424 shaders and 16 GB GDDR6 graphics memory with a 256 Bit memory bus. It supports PCIe 4.0 and will be available in different variants (80 - 175 Watt TGP currently known). The maximum Boost clock can vary from 1125 (80 W) to 1590 MHz (150W and up).

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. Thanks to the higher core count, the RTX 3080 Ti should be clearly faster than the old RTX 3080 Mobile and therefore well suited for 4K gaming.

The GA103S chip offers 7,424 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,712 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The GA103S integrates 58 Raytracing cores and 232 Tensor cores (e.g., for DLSS). The L2 cache is 4 MB. 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). Compared to the GA103, the GA103S integrates only a 256 Bit memory bus.

The GA103S 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 3060 Max-Q (for laptops, GN20-E3, Max-Q) is the former name for a RTX 3060 Laptop GPU with Max-Q technologies. In previous generations, the Max-Q name was used for low power versions. With the RTX 3000 series, every TGP-version can now use Max-Q technologies and all GPUs are called RTX 3060 Laptop GPU (60 - 115W).
