AMD Navi 33 chip utilizes a 5nm manufacturing process

As previously reported, AMD’s partners are preparing mid-range graphics cards based on the RDNA 3 architecture, with plans to showcase the Radeon RX 7600 series at Computex 2023. Equipped with Navi 33, this implies that the new graphics cards may be launched within the next two months.

According to Moore’s Law is Dead, a source who had access to early Radeon RX 7600 samples has revealed that the Navi 33 chip utilizes a 5nm manufacturing process (as opposed to the previously rumored 6nm), employs developmental graphics card drivers (which implies performance limitations), and has a total card power consumption of 175W. The performance surpasses that of the Radeon RX 6650 XT by approximately 11%, offering not only superior performance but also lower power consumption (the RX 6650 XT’s total card power consumption is approximately 185W to 190W).

Although this Radeon RX 7600 is an early sample running developmental drivers, such performance indicates that, with optimization, a 5% to 7% performance increase could potentially achieve levels comparable to the Radeon RX 6700 XT. If the total card power consumption remains at 175W, the Radeon RX 7600 would require only a traditional 8-pin connector to meet its power supply needs, suggesting a smaller cooling module and greater installation compatibility for gamers.

The Radeon RX 7600 is equipped with 8GB of GDDR6 video memory, identical to the existing Radeon RX 6650 XT, and features a 128-bit memory bus. It is understood that the core frequency of the Radeon RX 7600 will exceed 2.6 GHz.
