AMD’s RDNA 2 Silicon, CU counts and clock speeds reportedly confirmed

Thanks to AMD’s latest ROCm 3.8 software updates, a lot of information about the company’s RDNA 2 silicon has been revealed, including CU counts, clock speeds and power consumption targets.

These Navi 2X products are due to become AMD’s RX 6000 series of graphics cards, offering hardware specifications that stretch beyond the capabilities of today/s RDNA products, even when broader architectural changes are not considered. 

The Redditor stblr, has compiled a lot of data for AMD’s upcoming RDNA 2 series chips, revealing that AMD’s flagship Navi 21 silicon will feature 80 compute units and higher clock speeds than the company’s older Navi 10-based RX 5700 XT. This alone should give AMD a significant performance leap with its RDNA 2 product lines. 

AMD’s RX 5700 XT features a boost clock speed of up to 1905 MHz and a Game Frequency of 1755 MHz. With AMD’s Navi 21 silicon, clock speeds of between 2050 MHz and 2200 MHz are expected, as are relatively low power consumption targets when compared to Nvidia’s RTX 30 series. 

Radeon’s Navi 22 silicon will offer users 40 CUs, matching the RX 5700 XT’s Navi 10 silicon. This makes Navi 22 AMD’s RDNA 2 replacement of Navi 10, offering users AMD’s RDNA feature set, higher clock speeds and impressive power consumption figures. This silicon will likely be used to create AMD’s RX 6700 series products. 

Navi 23 will be AMD’s lower power Navi offering, catering to the lower end of the PC market. Navi 23 will also be AMD’s best silicon for mainstream gaming notebooks, especially if AMD’s performance-per-watt claims for RDNA 2 hold true. 

Based on this new information, AMD’s RDNA 3 Navi 31 silicon will also feature 80 CUs, suggesting that AMD’s RDNA 2 successor will feature redesigned CUs to enable a generational leap in gaming performance. 

The data for AMD’s Navi 1X silicon below appears to come from AMD’s low power RDNA Pro silicon. The data below may not be representative of future AMD RDNA 2 products. 

AMD hasn’t currently announced any performance numbers for its upcoming Radeon RX 6000 series. Radeon fans should expect a significant performance leap over Navi, thanks to the efficiency boosts of Radeon’s RDNA 2 architecture and the addition of new features like VRS, Mesh Shaders and DXR 1.1 support.
