AMD Navi 21 XT “Big Navi” GPU reportedly for Radeon RX 6900 XT reportedly 2.4 GHz clocks, 16 GB GDDR6 VRAM and 255W TDP


As reported by the specifications of the AMD Navi 21 XT “Big Navy” GPU for the Radeon RX 6900 XT graphics card Patrick shur Which is very reliable about its information. The AMD Radeon RX 6900 XT, according to reported specs, seems to be a beast of graphics cards with crazy clocks.

Patrick said in his tweet that the AMD Navi 21 XT GPU, reportedly the “Big Navy” GPU that all avid gamers are waiting for, will be a crazy chip. According to previous reports, the 21 XT GPU will be featured on the Radeon RX 6900 XT graphics card, but there are reports that a faster XTX variant exists which will be even faster.

Navi 21 XT GPU reportedly will be a powerhouse with a chip 2.4 GHz sports watch Which are the highest clock speeds we would be able to see on a consumer desktop-grade graphics card. This also suggests that we can expect higher frequencies considering Game and Boost Clock separately, as Game Clock is the average clock frequency that GPU can maintain in games while Boost Clock is the peak frequency that GPU hits. Can do.

The GPU is also called for a TGP (total graphics power) feature of 255W. This does not mean the power of the entire board, but the GPU itself. For comparison the GeForce RTX 3080 has a TDP of 320W and the GeForce RTX 3070 has a TDP of 220W.

The graphics card based on the Navi 21 XT GPU, which is reportedly the Radon RX 6900 XT, is called the 16 GB GDRD6. Memory Which we have seen in many previous leaks as well. For comparative measurements, the performance looks really close to the NVIDIA GeForce RTX 3080 graphics card, which is very impressive to hit AMD, and could be priced around US $ 499- $ 599 US if the Big Navy graphics card. , Then they will have a killer 4K solution in their hands.

Rogame had already indicated at least four SKUs for the Navi 21 (RDNA 2) GPU but we did not know anything other than the PCI ID. There is already active speculation about the exact specification and configuration of each SKU in terms of core counts, texture mapping units, and ROPs as we now know that GPUs have 5120 stream processor packs within 80 CUs.

According to Rogem, the Navi 21 GPU currently has the following SKUs:

  • Navi 21 XTX (0x731F: D0)
  • Navi 21 XT (0x731F: D1)
  • Navi 21 XL (0x731F: D3)
  • Navi 21 XLE (0x731F: DF)

AMD Radeon RX 6900 Series with Triple-Slot Cooling Solution:

As for the design itself, the Radeon RX 6000 flagship cooling design looks amazing with red and black design. The card has a triple axial-tech fan setup on the shroud and a large aluminum heat sink below it. The card has an LED-lit Radeon logo on the side and a large cut out for fans to vent hot air. The design is very reminiscent of the cooler, the founding version of the NVIDIA GeForce RTX 20 series. The card will feature dual 8-pin power and the display port will include a USB Type-C (VirtualLink), 1 HDMI and 2 DisplayPort connectors.

The card also has a fancy backplate with a retention bracket to keep it cooler in place. The Radeon RX “Big Navi” GPU looks like it will come in a standard 2-slot reference design that is similar to NVIDIA’s flagship RTX 3080, but not as huge as the triple-slot GeForce RTX 3090.

AMD will officially unveil its Radeon RX 6000 Series graphics card family on October 28. The second half of 2020 will surely be an interesting time for all hardware enthusiasts and mainstream PC gamers who are eager to upgrade their PCs with the best hardware.

How fast do you think AMD’s Big Navi (RDNA 2) GPU powered Radon RX graphics card will be?
