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 wanted to see how the RTX 3070 Ti SUPRIM X compares with the 3070 Ti Founders Edition. The RTX 3070 Ti SUPRIM X has a clock speed of 1860 MHz where the Founders Edition is slower at 1770 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. The RTX 3070 Ti SUPRIM X moved up to the top of the tightly bunched group of the RX 6700 XT’s along with the Founders Edition 3070 Ti. That lead grows bigger in the extreme detail and then in the ultra detail both 3070 Ti’s take the lead with the RTX 3070 Ti SUPRIM X having 272 points up over the Founders Edition.
The next two were both based on the Time Spy benchmark. One is the standard test and then there is the extreme detail level. Time Spy is DX12 based and the last few generations of Nvidia cards have been doing very well in both Time Spy tests. You can see how the RTX 3070 Ti SUPRIM X has now jumped up higher in the chart compared to the Fire Strike benchmarks and once again the RTX 3070 Ti SUPRIM X has a nice lead on the Founders Edition in both detail levels. This doesn’t get it close to the RTX 3080 but pulls even more away from the 2080 Ti.
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 the RTX 3070, Ti SUPRIM X has a 2.8% increase up over the 3070 Ti Founders Edition. That is far from enough to catch up to the 6800XT but it does help.
