AMD Radeon RX 6800 XT Review - RX 6000 SeriesAMD is known to push for 4K gaming with its previous “high-end” graphics card releases with some units packing in liquid cooling solutions out of the box. Today, it seems like AMD has finally achieved glorious 4k gaming via the RDNA 2 Architecture without the caveats as even the cheapest RX 6000 GPU is marketed for 4K Gaming.

AMD Radeon RX 6800 XT Review - Infinity Cache

AMD’s main goal with the RDNA 2 architecture is to make it very power efficient which led to the debut of AMD’s Infinity Cache solution. Infinity Cache is a new method on how data is delivered in GPUs. Every card in the Radeon RX 6000 family is equipped with a 128MB of AMD Infinity Cache enabling high-performance bandwidth vs GDDR6 all while consuming far less power.

AMD Radeon RX 6800 XT Review - DX12 UltimateNvidia was first to market with full DirectX 12 support, now known as DX 12 ultimate. AMD’s RDNA 2 architectural improvements allow the brand to catch up and finally support the full level API as well as Ray Tracing, variable-rate shading, mesh shaders, and sampler feedback.

AMD Radeon RX 6800 XT Review - Ray Tracing

AMD’s Ray Accelerators is AMD’s answer to Nvidia’s RTX Ray Tracing via RT cores. Each RDNA 2 Compute Unit(CU) includes a dedicated Ray Accelerator that can calculate up to 4 ray/box intersections or one ray/triangle intersection every clock. We’ll see how AMD’s first take on Ray Tracing via Ray Accelerators compares against Nvidia’s RT cores.

AMD Radeon RX 6800 XT Review - Smart Access Memory

Processors only access a fraction of GPU memory, typically around 256MB resulting in a less efficient data transfer and restricted performance AMD Smart Acess Memory or SAM enables more memory space to be mapped to the base address register(BAR) resulting in performance gains in select games, particularly those who are memory heavy. With SAM enabled, the whole PCIe bandwidth is utilized allowing AMD processors to fully access the entire GPU memory. As of writing, Smart Acess Memory can only be enabled if you meet the necessary hardware requirements as well as the latest BIOS and drivers.

Smart Access Platform Requirements

  • AMD Ryzen 5000 Series Processors
  • AMD Radeon RX 6000 GPUs
  • AMD B550/X570 Series Motherboards

Above 4G decoding and Re-size BAR support must be enabled to enable Smart Access Memory. These settings can be enabled on the BIOS and are usually found under PCI-Subsystems.

Our Verdict
The way AMD shocked the industry with the RX 6800 series performance is definitely astonishing, so much that it downplays AMD's struggle with the Ryzen CPU line snatching the crown from Intel. To put it simply, AMD's Radeon RX 6800 XT is on par with the RTX 3080 but it comes with several asterisks. If you're willing to forego Nvidia's shiny RTX exclusive features, AI-performance enhancement, and overall stable drivers, then the RX 6800 XT is a more than good enough alternative. What the AMD RX 6800 XT or the RX 6000 series lack in thermals and feature sets, they make up with brute force performance and relatively competitive pricing.
