AMD Radeon RX 6600M vs AMD Radeon RX 6600

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.

AMD Radeon RX 6600

The AMD Radeon RX 6600 is a mid-range desktop graphics card that is based on the RDNA 2 architecture and uses the Navi 23 chip. It offers 1,792 shaders and 8 GB GDDR6 VRAM with a 128 bit memory interface (14 Gbps, 224 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 RX6600.

The gaming performance of the RX 6600 is comparable to a GeForce RTX 2060 Super (Desktop). The previous generation Radeon RX 5600 can be easily bested. Therefore, the RX 6600 is best suited for demanding games in 1080p and high details.

The power consumption is rated at 132 Watt (TGP) by AMD and therefore offers a rather low power consumption compared to the previous generations with similar performance.
