AMD Radeon RX 7900 XTX & RX 7900 XT 3DMark GPU benchmarks leak, trading blows with NVIDIA RTX 4080

The first 3DMark GPU benchmarks for AMD’s Radeon RX 7900 XTX and RX 7900 XT graphics cards have been leaked by Videocardz.

AMD Radeon RX 7900 XTX & RX 7900 XT Leaked 3DMark Performance Benchmarks Show Trading Blows With NVIDIA RTX 4080

The benchmarks give us a look at the synthetic performance of AMD’s upcoming Radeon RX 7900 XTX and RX 7900 XT graphics cards launching next week. Benchmarks include 3DMark FS (Fire Strike) and 3DMark TS (Time Spy), both of the most popular to date. Each benchmark was run on two presets. For 3DMark Time Spy, these presets are 4K Extreme and 1440P Performance while for Fire Strike, these are 4K Ultra and 1440P Extreme.

Starting with the 3DMark Time Spy performance score, the AMD Radeon RX 7900 XTX is over 50% faster than the Radeon RX 6950 XT while the Radeon RX 7900 XT is over 25% faster. Meanwhile, the NVIDIA GeForce RTX 4090 is 12% faster than the 7900 XTX and 18% faster than the RX 7900 XT.

In 3DMark Time Spy Extreme, the difference is smaller as the Radeon RX 7900 XTX and RX 7900 XT are only 5% slower than the RTX 4080 while being about 50% faster than its predecessor, the Radeon RX 6950 XT.

Moving on to the 3DMark Fire Strike Extreme numbers, this particular benchmark has always been better on AMD cards and we see similar results in this benchmark. The Radeon RX 7900 XTX can beat the RTX 4080 (even overclocked) here while the RX 7900 XT is within reach. The 7900 XT also ends up being 30% faster than the Radeon RX 6950 XT graphics card.

Finally, we have the 3DMark Fire Strike Ultra benchmark results where the Radeon RX 7900 XTX & RX 7900 XT trail the NVIDIA RTX 4080 by a bit but not by a huge margin. This may be due to insufficient optimizations at low resolutions as both cards target the 4K gaming segment.

Again, these are just synthetic performance benchmarks and do not represent actual gaming performance. It remains to be seen how the cards perform in games, especially ray tracing titles as all console and PC games seem to be going like this. So it is wise to wait a few more days before making a purchase.
