AMD Radeon RX 6800XT alleged 3DMark scores hit the web

Synthetic benchmark results of Radeon RX 6800XT graphics cards seem to be in the wild. 

AMD Radeon RX 6800XT, a tale of 3DMark

There are now three sources providing benchmark results of Radeon RX 6800 XT based on the UL 3DMark GPU testing software stack.

AMD Radeon RX 6800XT is the Navi 21-based graphics card based on RDNA2 architecture. This is the only Big Navi variant that will be available to board partners at launch. Naturally, board partners are the prime source for leaks (as they have always been). Thus, the results that are surfacing right now come from their internal evaluations.

Three different sources have posted their own benchmark results, which may not necessarily correspond to each other. We collected this data and quickly made this chart:

*Based on Combined Score (not Graphics only)

Igor’sLAB

Igor Wallosseek shared the data from two different sources (percentage comparison and score comparison). He claims that the data was generated from benchmarks run by board partners offering both AMD and NVIDIA graphics cards (so probably ASUS, MSI or Gigabyte).

Igor Wallossek:

If you compare the percentage differences, the picture in Ultra-HD is very different: While the Firestrike Extreme benchmark is supposed to be over 18 percent ahead for the Radeon RX 6800XT, the Timespy Extreme is only a good 3 percent. If one then adds the raytracing implementation of the Port Royal, the GeForce RTX 3080 FE is then proudly 22 percent ahead of the new Radeon. Here, the WQHD resolution of the default settings has been manually set to Ultra-HD, probably for the sake of uniformity. The older GeForce RTX 2080 Ti doesn’t even do too badly in the RT benchmark, but has to leave springs in the other benchmarks.

Wccftech

It appears that Wccftech received very similar results to Igor, also divided into two groups: percent different and score difference:

CapFrameX:

The developer of the benchmarking utility posted initial performance figures for the Big Navi, without confirming which SKU that is. The SKU would allegedly offer 8% better performance than RTX 3080 in Fire Strike Ultra, a DirectX 11 based 4K benchmark.

@KittyYYuko

A person who we still remember from a different nickname (Kitty Corgi) has provided many leaks that have already been confirmed. Yuko provided results in four different benchmarks of the Navi 21 XT sample, which allegedly features 80 Compute Units. However, based on what we know the 80CU version is exclusive to the XTX variant.

Kitty’s results have been put together by @harukaze5719:
