AMD Radeon RX 6000 officially presented with RDNA2 architecture

The new AMD Radeon RX 6000 graphics cards with RDNA2 architecture have been officially presented, a long-awaited leap in performance and integration of new technologies. Let’s see what this new generation offers us.

The new AMD Radeon RX 6000 Series graphics cards come to compete in gross performance directly against NVidia’s 3000 Series. With the new RDNA2 architecture at 7nm we already have in our PCs hardware support for many of the techniques we will see in the new generation games of Xbox Series X and PS5.

For now, we have released only three models of these graphics cards, we have in the high range the AMD Radeon RX 6900 XT that enters to compete with the NVidia 3090, a model Radeon RX 6800 XT to similar to the top of range with less Compute Units (CU) that competes against the Nvidia 3080 and another that if you change more radically its configuration as is the Radeon RX 6800 that competes against the Nvidia 2080Ti. All of them have the new 128 MB Infinite Cache integrated and a 256 bit interface.

One of the most interesting points of the new AMD Radeon RX 6000 Series GPUs is the inclusion of the Infinity Cache inside the die of the graphics processor, this 128 MB cache allows a performance improvement of up to 2x in certain scenarios. Thanks to this system AMD can mount GDDR6 memories obtaining results that can compete with the GDDR6X much more expensive and with stock problems.

On the other hand AMD presents the AMD Smart Access Memory system that connects directly the AMD Ryzen 5000 processors with the memory of the GPU, with this you get direct access to resources and reduction of the lag between components. To use this system we need a motherboard with B550 or X570 controller. It has also integrated the Rage Mode to overclock directly by pressing a button.

AMD is the only one that can offer a complete combo between its AMD Ryzen 5000 processors + Radeon RX600 GPU + FreeSync monitors that synchronize all its components to reduce response times.

These new graphics cards have full support for DirectX 12 Ultimate and all its advanced features, plus it is possible to use DirectStorage to directly access data from our NVMe disks and speed up load times significantly. It also integrates all the FidelityFX image enhancement features supporting 35 games for now but with many more to come.

In terms of ray tracing performance we have the Ray Accelerator (RA) solution that integrates one ray accelerator unit for each Compute Unit (CU) integrated in the graphics processor. This system uses DirectX 12 Ultimate and its DirectX Raytracing (DXR) feature, the same ray tracing system that we will see in the Xbox Series X consoles. The performance for the tests performed is 25% below its direct competitor from Nvidia.

In addition, the AMD Radeon RX 6000 Series GPUs offer full HDMI 2.1 support, with VRR (Variable Refresh Rate) and other features that enhance performance and connectivity with our next-generation displays. It also has hardware acceleration AV1, the new codec that comes to be implemented in all streaming systems of the main content distributors or to transmit live efficiently.

Without a doubt the new AMD Radeon RX 6000 are very interesting products because of their features, especially if we are going to use them in conjunction with the new AMD Ryzen 5000 processors.  We are left with the doubt that weapon will use AMD to fight against the NVidia DLSS system that offers a spectacular improvement of performance by AI, it is rumored that they are working on a global solution but for now in this area we do not have news.

The new AMD Radeon RX 6800 XT and Radeon RX 6800 will be available on November 18th for a price of $579 and $649, the top of the range AMD Radeon RX 6900 XT will be available on December 8th for a price of $999.
