Radeon RX 6000, what do we know about it?

The Radeon RX 6000 , also known as Big Navi or Navi 21, will be unveiled by AMD on October 28th. During the Radeon RX 5000 presentation earlier this month, AMD provided a preview of this new card.

Some information about its configuration has leaked

The full configurations of the Radeon RX 6000 series, based on the RDNA2 architecture, will be unveiled by AMD on October 28th. However, some details about its configuration have already surfaced. Rumors suggesting that the Big Navi cards would operate at frequencies exceeding 2 GHz appear to be well-founded. Indeed, according to Videocardz, the Navi 21 XT series will have a base clock speed of 2.4 GHz . The entry-level cards will run at 2.3 GHz, and the Navi 21 XL series will have a clock speed of 2.2 GHz.

According to some leaks, there appears to be a significant difference between the base, game, and boost clock speeds. For the XT series, the base clock speed is said to be around 1.5 GHz. It will increase to around 2.1 GHz in game mode and reach a peak of 2.4 GHz in boost mode. For the XL series, the base clock speed is around 1.4 GHz, then 1.9 GHz in game mode, and will reach 2.2 GHz in boost mode. There are therefore substantial jumps between the base, game, and boost clock speeds, roughly 500 MHz between the base and game clock speeds, and then 300 MHz between the game and boost clock speeds.

The performance of the Big Navi

In terms of configuration, the Radeon XT series is expected to have 16GB of GDDR6 memory with a 256-bit bus . The TDP is rumored to be around 250 Watts. Previewed on October 8th, the Big Navi features three fans and is powered via an 8-pin PCIe connector.

Big Navi's power is approaching the performance of Nvidia's GeForce RTX 3000 series. AMD CEO Lisa Su promised that these new cards can easily deliver 60 FPS at 4K resolution . According to tests conducted by AMD, the frame rate reaches 88 FPS on Call of Duty: Modern Warfare and 73 FPS on Gears of War 5 in UHD. It should be noted that these tests were performed with ray tracing disabled.

What's most surprising about this story is the huge discrepancies between the base, gaming, and boost clock speeds. We don't know if AMD is deliberately spreading these rumors to create a surprise effect and confuse its competitors. But in any case, we'll know the actual clock speeds of these Big Navi processors within a week.
