LuxMark v4.0
Next up is LuxMark, a long-time standing OpenCL benchmark. We are using the newest version 4.0 which provides new render scenes supporting Path Tracing. The two scenes we are going to test are “Hall Bench” and “Food.” Hall Bench is a Path Tracing + Global Illumination test. The Food benchmark is a pure brute force Path Tracing test. The result given is an overall score.
In the Hall Bench test above the Radeon RX 6700 XT improves upon the Radeon RX 5700 XT by 24%. Unfortunately, it is thoroughly trounced on by the GeForce RTX 3060 Ti and GeForce RTX 3070. The GeForce RTX 3060 Ti is 22% faster, and the RTX 3070 is 39% faster. Once again, if the RX 6700 XT is priced closer to RTX 3070, the RTX 3070 is massively faster here.
In the Food bench above the Radeon RX 6700 XT is 18% faster than the Radeon RX 5700 XT. However, once again the RTX 3060 Ti and RTX 3070 are faster. The RTX 3060 Ti is a whopping 47% faster and the RTX 3070 is a huge 70% faster. Remember, this is OpenCL vs. OpenCL here, same renderer.
SPECviewperf 2020
SPECviewperf 2020 is a traditional benchmark for testing workstation application performance on GPUs. It uses very common and standard applications used in the professional workstation-class arena. We are using the new 2020 version which includes newly updated tests. The applications tested are 3dsmax, catia, creo, energy, maya, medical, snx and solidworks. In our graphs below, the green bar is RTX 3070, the grey bar is RTX 3060 Ti, the orange bar is RX 6700 XT and the blue bar is RX 5700 XT. We are running these tests at 3840×2160 (4K.)
Let’s start with 3dsmax. The Radeon RX 6700 XT does provide a big upgrade from the Radeon RX 5700 XT here, 64% which is pretty significant. The RX 6700 XT performs just under the RTX 3060 Ti, but they are close. However, the RTX 3070 is 12% faster than the RX 6700 XT. At least the RX 6700 XT is sort of keeping up in this app, better than the RX 5700 XT anyway.
Now let’s look at catia. This one surprised us, the RX 6700 XT is actually just a smidge above the RTX 3060 Ti finally. However, the RTX 3070 is still faster by 12%.
Things fall back again in creo though, the RX 6700 XT falls way back from even the RTX 3060 Ti. The RX 6700 XT doesn’t seem to be that much faster than the RX 5700 XT here. The RTX 3060 Ti is a big 29% faster and the RTX 3070 is 37% faster.
Then things take a turn in the energy test, the Radeon RX 6700 XT for the first time in all the testing is actually faster than the RTX 3070, slightly. Though, the number grouping is pretty tight for this test.
Things go back again though in the maya test. The RX 6700 XT is falling way behind the RTX 3060 Ti. The RTX 3060 Ti is 16% faster and the RTX 3070 is 33% faster.
The medical test is another test of tight groupings. However, like the energy test, the Radeon RX 6700 XT is the faster video card in this application.
We also see a very positive result for the Radeon RX 6700 XT in snx. For whatever reason, the two RTX video cards fall way behind here, the reason is unknown. This puts the Radeon RX 6700 XT on top by 310% compared to the GeForce RTX 3070! Either something is bottlenecking the RTX cards here, or the RX 6700 XT has some kind of advantage we are unaware of in this application.
In solidworks the Radeon RX 6700 XT falls behind again though, the RTX 3060 Ti is 37% faster and the RTX 3070 is 57% faster.
