Ahead of next week’s RDNA 2 event, _rogame has shared the alleged base, game, and boost clock speeds for AMD’s flagship Radeon RX 6000 Series graphics cards.
Navi 21 XL (Radeon RX 6900?) will supposedly feature a base clock of 1,350 to 1,400 MHz and a game clock of 1,800 to 1,900 MHz, while its boost clock will be 2,100/2,200 MHz.
Navi 21 XT (Radeon RX 6900 XT?) will supposedly feature a base clock of 1,450 to 1,500 MHz and game clock of 2,000 to 2,100 MHz, while its boost clock will be 2,200 to 2,400 MHz.
What’s interesting is how much lower the base clocks are in comparison to the Radeon RX 5700 flagships. The Radeon RX 5700 XT 50th Anniversary Edition and Radeon RX 5700 XT have base clocks of 1,680 MHz and 1,605 MHz, respectively, while the Radeon RX 6900 Series purportedly taps out at 1,500 Mhz.
On the other hand, the boost clocks are a clear and welcome improvement, with the Radeon RX 6900 XT potentially boosting to 2,400 MHz. In contrast, the Radeon RX 5700 XT 50th Anniversary Edition only boosts to 1,980 MHz.
The clock speeds appear to line up with a Navi 2X table that was previously shared at Chiphell’s forums. According to the chart, there will be at least seven Radeon RX 6000 Series models, the most powerful of which will be a match for NVIDIA’s GeForce RTX 3090.
