Radeon RX 6000: AMD is ahead of Nvidia

in benchmarks

In-house measurements of the Radeon RX 6900 XT and Radeon RX 6800 (XT) should show that Nvidia's Geforce RTX 3090/3080 are slower.

Following the announcement of the Radeon RX 6000, AMD published the benchmarks it created itself in an expanded form. According to the measurements , Nvidia's current top model, the Geforce RTX 3090 , is overtaken by the Radeon RX 6900 XT in 4K on average and the slightly slower Geforce RTX 3080 by the Radeon RX 6800 XT in 1440p on average.

The test system consisted of a not yet available Ryzen 9 5900X with twelve cores and Zen 3 architecture, plus 16 GB of RAM and an X570 mainboard with PCIe Gen4. With this structure, however, the Radeon RX 6000 benefit from Smart Access Memory (SAM), which is only possible with the Ryzen 5000 and allows the CPUs to access the full GDDR6 of the graphics cards.

According to AMD, the advantage of SAM amounts to 5 percent to 11 percent, so this must be taken into account in the benchmarks. In 1440p the Geforce RTX 3090 is at least overtaken by the cheaper Radeon RX 6900 XT in nine out of ten games, sometimes the Radeon RX 6800 XT and in Forza Horizon 4 even the Radeon RX 6800. The Geforce RTX 3080 again loses against cheaper Radeon RX 6800 XT also in nine out of ten games.

The Nvidia cards catch up a bit in 4K: The Geforce RTX 3090 creates a 5: 5 tie with the Radeon RX 6900 XT and the Geforce RTX 3080 can prevail against the Radeon RX 6800 XT in six out of ten games. Taking into account the Smart Access Memory, the Ampere models with other CPUs should be in the front, for example with a Core i9-10900K (test) or Ryzen 7 3800XT (test) . In view of the price differences of 500 US dollars (RTX 3090 vs RX 6900 XT) and 50 US dollars (RTX 3080 vs RX 6800 XT), AMD's values are still an announcement.
