Synthetic Benchmarks

As always I like to start my testing with a few synthetic benchmarks. 3DMark especially is one of my favorites because it is very optimized in both Nvidia and AMD drivers. It's nice to not have to worry about it being favored too much either way and the repeatability of the results makes it a nice chance to compare from card to card, especially with this being our first RX 6800 XT and the Merc 319 having a higher clock speed of 2340 MHz compared to the stock 2250 MHz.

The first round of tests were done in the older Fire Strike benchmark which is a DX11 test. There are three detail levels, performance, extreme, and ultra and the 6800 XT just jumps completely off the charts. Nvidia’s last few generations haven’t liked the DX11 titles as much, but it is amazing how well Big Navi did here.

The next two were both based on the Time Spy benchmark. One is the standard test and then there is the extreme detail level. In these, the gap between the 6800XT wasn’t nearly as large. It did still come in above the overclocked 3080 in the basic Time Spy test, but with the extreme, the numbers were flipped with both 3080’s coming in ahead. The Merc 318 was still in this lead pack (without the 3090) which is out ahead of the 3070 as well as the older 2080 Ti. If you would have asked me last year, my guess would be AMD matching or just barely beating the 2080 Ti, so this alone is huge. Not counting the 6900 XT in the future as well.

Because my whole section of RTX and DLSS testing doesn’t apply to AMD I have the ray tracing test from 3DMark included here as well. Port Royal uses Microsoft DirectX Raytracing which AMD has support for as well. The 6800 XT didn’t catch up to the RTX 3080 here but did outperform the 2080 Ti with its score of 9400.

The last test was using the Unigine based Superposition benchmark and I tested at 1080p with medium detail and again at 1080p with the extreme detail setting. In the extreme detail setting which this graph is sorted the two 3080’s did come in slightly ahead. But the medium detail setting also impressed here being significantly higher than all of the 3000 series cards.
