AMD Radeon RX 6600 XT vs AMD Radeon RX 6550M

AMD Radeon RX 6600 XT

The AMD Radeon RX 6600 XT is a mid-range desktop graphics card that is based on the RDNA 2 architecture and uses the Navi 23 chip. It offers 2,048 shaders and 8 GB GDDR6 VRAM with a 128 bit memory interface (16 Gbps, 256 GB/s max).

The RDNA2 architecture offers new features like SAM (Smart Access Memory) and Infinity Cache. PCIe 4.0, RIS (Radeon Image Sharpener) and Raytracing support are also included in the RX6600XT.

The gaming performance of the RX 6600 XT is comparable to a GeForce RTX 3060 (Desktop). The previous generation Radeon RX 5600 XT can be easily bested. Therefore, the RX 6600 XT is best suited for demanding games in 1080p and high details.

The power consumption is rated at 160 Watt (TGP) by AMD and therefore similar to a GeForce RTX 3060 (170 Watt).

AMD Radeon RX 6550M

The AMD Radeon RX 6550M 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 2560 MHz. Compared to the RX 6500M, the 6550M offers an increased core clock (+17%) but the memory bus i cut in half (64 versus 128 Bit).

The performance should be slightly higher than 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 RX6550M is specified at a TDP of 50 - 80 Watt and therefore best suited for normal multimedia laptops.
