AMD Radeon RX 6550M vs NVIDIA GeForce GTX 1070 SLI (Desktop)

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.

NVIDIA GeForce GTX 1070 SLI (Desktop)

The Nvidia GeForce GTX 1070 SLI for desktops is a combination of two GTX 1070 graphics cards in SLI mode. Each card renders one frame at a time (AFR mode) but depends for most games on a good profile in the driver. Therefore, the performance can range from no gains over a single GTX 1070 to up to 90% faster performance. In most games with SLI support, the GTX 1070 SLI is therefore faster than a single GTX 1080. However, sometimes the combination also suffers from micro-stuttering.

The technical details of the card are identical to a single GTX 1070 (see for more information) and the power consumption is doubled (2x 150 = 300 Watt).
