Radeon RX 6900 XT is the official new halo product of AMD. Surpassing AMDs own high-quality graphics card Radeon RX 6800 and Radeon RX 6800 XT By creating a fully enabled Navi 21 with 80 computer units.
For quite some time we have seen the most expensive and latest generation GPUs sit. We have seen AMD sell their GPU priced at 1000 USD and this rate is more on Radeon pro-Duo (2016).
This duo AMD was limited in quantity. Rx 6800 and Rx 6800 XT want to show the best performance and try to show competitive performance to the Geforce 3090. The main goal of AMD was to make their own marketplace in the place of Geforce 3090.
This year 2020 comes with a pandemic of Covid-19. Because of this pandemic situation, everything has been delayed. Like other things, AMD takes some time to release and announce their best graphics card.
AMD presents its products as RDNA2-based technology. By this, a new graphics technology was added. Hybrid DirectX Ray Tracing. Already Two years old NVIDIA was pioneering with their RTX 2000 series.
AMD made some delay to call the original NAVI GPU. That’s why the landscape of graphics changed, and the plan of AMD’s roadmap was changed.
At this moment Microsoft and Sony were embedded with AMD technology and Ray Tracing was going to be supported because of this set of trends we can see the desktop graphics announced.
The triplet of 6800 and 6900 graphics cards is a very closed GPOU. In Fact, the Big NAVI holds the same GPU. Just extra is binned and somewhat weakened. The GPUs are optimized for 7 main nodes derived from TSMC. In this card, we get PCle 4.0 interface compatible.
With 64 shader units and 5120 shading processors, Radeon RX 6900XT received 80 activated multiplied CUs.based On a 256-bit memory bus this graphics card got 16GB of GDDR6 memory.
You need to know the GDDR6X memory for RTX 3080 and 3090. This means the bandwidth of this memory is 512 GB/s. 300 watts are listed for this product by TDP. The clock was boosted very highly by 2250 GHz.
Which is like two siblings. 128 MB infinity cache makes this card more special than others. Radeon RX 6900 XT is the finest card of the NVIDIA GeForce RTX 3090. The price of this best graphics card is $999 USD which is cheaper than Geforce RTX 3090.

GPU architecture and specs
In this release, AMD focused on the high end of the enthusiast class. But we have no doubt that the Radeon RX 6900 XT is an RDNA-based structure.
Radeon RX 6900 XTs GPU is holding 26.8 billion transistors. By AMD they improve 50% performance and make it double their last generation performance. Let’s look at the overview of some product specifications…
Radeon RX 6900 XT

|Memory bandwidth||512 GB/s||512 GB/s||512 GB/s||448 GB / s|
|Infinity Cache||128 MB||128 MB||128 MB|
In this overview, we can see clearly that AMD is able to double stream processor count for the fully enabled GPU.
Moreover, there is a huge difference in transistor count, of course, this is a big chip. We also observed that a fully enabled Big Navi GPU keeps 80 computer units. Each computer unit keeps 64 shading cores. That’s why when it is multiplied it ends on 80×64= 5120 shading cores.
Infinity cache is one of the most important changes from previous GPU architecture. Here anyone can think why infinity caches ??
Well. The infinity cache because GDDR6 is cheaper than GDDRX. This amount helps the bill of other graphics cards. In fact, 16 GB AMD faces the challenges of 256-bit limits.
512-bit is much-complicated more wire-wise and signal that’s why they add a cache memory which helps to take offload for the memory bus. That is helping Raytracing.
So there simply set up an infinity cache memory. And for this, the cache memory is placed into its own chip itself. Another reason is that the GPU of Navi 21 is bigger than the Navi 10. Moreover, because of IC memory, we get significant, faster data in a significant manner.
Now Hardware installation of every graphics card is very straightforward. When the graphics card is placed into the PC make sure to connect with the PC and surely with any external power connector like 12-pin PEG or 6/8- pin power connectors.
Make sure a power supply has its own PCLe PEG power supply. AMD Radeon RX 6900 XT calculates your power supply. It provides the best power supply depending on your PC.
It provides a power supply as needed for your PC at half load value. So during gaming, you use 300 watts on average, but by generic rules, AMD recommends you 600-watt power supply.
Once installed boot the windows and install the best drivers and after reboot, all should be working. Here no required configuration so just installed and feel the real advantage of this best graphics card AMD RADEON RX 6900XT.
- Excellent 4k and 1440p
- gaming experience
- Lower TDP
- Launch stock is low.
- High price
- Lacks lead in some games
AMD can provide a heavy GPU that can provide super strong shading performance, but in Raytracing it lacks a bit. Overall the performance of this product is surely great.
Radeon RX 6900 XT is surely the best graphics card. This product is best with the proper amount of memory. The performance of this product is great. However, if you want premium quality RX 6900 XT is the best option for you.
