AMD Radeon RX 6550S vs NVIDIA Quadro RTX 4000 (Laptop) vs AMD Radeon RX 6600M

AMD Radeon RX 6550S

The AMD Radeon RX 6550S is a mobile entry-level graphics card based on the Navi 24 chip (RDNA 2  architecture) manufactured in the modern 6nm process. It features 1024 cores (16 CUs - compute units) and 4 GB of fast GDDR6 graphics memory connected with a 64 Bit memory bus. The chip also includes 16 MB Infinity Cache. The game clock speed is specified at 2170 MHz. Low power version of the Radeon RX 6550M with lower clock speeds (-15%) and a lower maximum TGP (-37%).

The performance should be similar to an average RX 6500M, as long as the memory bandwidth reduction wont has a too big impact.

The Navi 24 chip is manufactured at TSMC in the modern 6nm process and should offer a good energy efficiency. The RX6550S is specified at a TDP of 35 - 50 Watt and therefore well suited for thin and light laptops.

NVIDIA Quadro RTX 4000 (Laptop)

AMD Radeon RX 6600M

The AMD Radeon RX 6600M is a mobile mid-range graphics card based on the Navi 23 chip (RDNA 2  architecture) manufactured in the modern 7nm process. It features 1,792 cores (28 CUs - compute units) and 8 GB of fast GDDR6 graphics memory connected with a 128 Bit memory bus. The chip also includes 32 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The power consumption (TDP settings) ranges from 50 - 100 Watt with different clock speeds (similar to Nvidia).

At 100 Watt the game clock reaches 2177 MHz (max boost 2416 MHz) and the performance should be similar to a RTX 3060 for laptops. When Raytracing effects are activated, it falls behind the GeForce GPUs.

The Navi 21 chip is manufactured at TSMC in the modern 7nm process.
