Firestrike is an excellent tool for our purposes and was the reason that I have been so vocal that it is not the windows scheduler or CCX thread switching as the primary cause of the performance issues (yes there is a small amount of latency added when threads switch but that is symptomatic of the low memory frequency and high memory latency. You don't use it in this situation looking at absolute numbers. The total score really doesn't mean much for out purposes, You use the balance of the individual component scores to identify trends.
FS Graphics scores for a given GPU all fall within a reasonably small range for that particular model of card eg a GTX 1070 will run roughly about 19000 stock and about 21000 when overclocked, give or take. That remains true on both Intel and Ryzen systems. That test Loads the GPU without stressing the CPU very much
FS Physics scores likewise tracks the CPU frequency/IPC pretty consistently for both Intel and Ryzen. At the same clocks, an R7 and a 6900K will both roughly sore about the same physics score. That has been true since release of the Ryzen CPUs. This test stresses the CPU and puts minimal load on the GPU. If it was thread switching causing the major part of the problem, you would see it impacting the physics score as well but both brands of CPU tend to track each other quite well. The 6900K only pulls ahead if it is overclocked above about 4.1Ghz.
The FS combined score demonstrates where the performance is being impacted. That is in the part of the system between the cores and the GPU itself that has to run double duty supporting both GPU and CPU related memory traffic and traffic between the CPU and the GPU over PCIe. 6900K will do a 9000-10000 Combined score and the R7 and R5 Ryzens have, until the recent memory OC breakthroughs, was stuck at the 6000-6500 level. Since 3200 c14 single rank speeds became a reality, The best scores are now at around 8500 which is almost matching the Intel equivalent chip. Dual Rank memory with the extra interleaving also seems to help the performance as well.
If a score of 10000 pops up, we then have the chance of analyzing what is happening on that system that no-one else is doing
Being forthright, you need to let that go. Furthermore, this is a stability thread. If you want to start a thread comparing 3DMark scores you can do so yourself, however, there is already one in the graphics section.
