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 when comparing with the same GPU. In this case, I am curious to see how the RTX 5080 Founders Edition compares with the RTX 5090 FE, but the better comparisons will be against the previous xx80 cards and from AMD the 7900 XTX.

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. The RTX 5080 Founders Edition scored a 79045 in the base Fire Strike test sitting above the RX 7900 XTX but below the RTX 4090. It was an improvement over the RTX 4080 by 20%. In Fire Strike Extreme it scored a 39871, putting it over the 7900 XTX again and behind the 4090 by a good margin. That is a 20% over the RTX 4080 once again. Then for the last Fire Strike test, Fire Strike Ultra the RTX 5080 Founders Edition is once again sitting above the 7900 XTX and below the 4090 but the gap between it and the 4090 is larger here. Its 21262 score put it as a 24% improvement over the RTX 4080.

The next two were both based on the Time Spy benchmark. One is the standard test and then there is the extreme detail level. For the standard Time Spy, the RTX 5080 Founders Edition scored a 32642, once again sitting between the RTX 4090 and the RX 7900 XTX. Compared to the RTX 4080 it was a 16.8% improvement, a little lower than what we saw in the DX11-based Fire Strike tests. For Fire Strike Extreme it scored a 16244, a 17.9% improvement over the RTX 4080 and it sits way out in front of the RX 7900 with its 14786. The RTX 4090 however is still significantly higher with a score of 19009.

I did also test using the new 3DMark Speed Way which is one of their latest benchmarks and Port Royal as well. Speed Way is DX12 as well but combines more future-focused tech like Ray Tracing which up until its release where only used in feature tests, not full benchmarks. The RTX 5080 Founders Edition isn’t sitting ahead of the 7900 XTX for this test, the 7900 XTX was down lower in the chart and the RTX 5080 Founders Edition is way out in front of the 4080 SUPER here with its 9039 score putting it 23.4% ahead of the RTX 4080 and 41% over the RTX 4080 SUPER. For Port Royal the result is similar, 24.8% ahead of the RTX 4080 and 21.9% ahead of the RTX 4080 SUPER.

The last test is the newer 3Dmark Steel Nomad benchmark. Officially this is the replacement for the Time Spy benchmark. It is a DX12 benchmark and doesn’t include ray tracing but is updated to better take advantage of modern cards. The RTX 5080 Founders Edition has a larger lead over the two RTX 4080s and the RX 7900 XTX here with its 8198 score putting it 25.8% ahead of the 4080, 24.6% ahead of the 7900 XTX, and 22.6% ahead of the 4080 SUPER. It is still behind the RTX 4090 here but the gap is a little smaller than in the other tests.
