AMD Radeon RX 6600M ‘Navi 23’ Laptop RDNA 2 GPU Tested, Slower Than The NVIDIA RTX 3060-December 2024-www.yitit.com

The first unofficial benchmarks of the AMD Radeon RX 6600M RDNA 2 GPU based on the Navi 23 SKU have landed. The benchmarks were posted over at Zhuanlan (via HXL) and show how well the latest RDNA 2 GPU competes against mainstream laptop offerings from NVIDIA.

AMD Radeon RX 6600M 'Navi 23' Laptop GPU With RDNA 2 Architecture Benchmarked, Slower Than The NVIDIA RTX 3060

The AMD Radeon RX 6600M is the first graphics chip to make use of the Navi 23 GPU SKU. The chip has yet to make an entrance on the desktop front so this is the first time we are actually looking at its real benchmarks. The chip was tested on an AMD Ryzen 7 5800H laptop which featured 16 GB of DDR4-3200 (Single Rank x8) memory. The same test platform was also used to test the competition which included the NVIDIA RTX 3060 and the RTX 3050 Ti. Before we get into the benchmarks, let's quickly recap the specifications for the Radeon RX 6600M.

AMD Radeon RX 6600M 'RDNA 2' Mobility Graphics Chip Specifications

When it comes to specifications, the AMD Navi 23 RDNA 2 GPU for the Radeon RX 6600M & Radeon Pro W6600M is expected to feature up to 28 CUs or 1792 stream processors. It will also come with up to 8 GB GDDR6 memory running across a 128-bit bus interface and with TGPs ranging up to 100 Watts. The AMD Navi 23 GPUs are additionally going to feature 32 MB of Infinity Cacheand will be the smallest Navi chip to house the brand new cache technology. Discrete GPUs below the Navi 23 such as Navi 24 and the integrated RDNA 2 chips on Van Gogh APUs are not going to feature the tech.
