Ryzen 9 3950X vs. Intel Core i9-9960X rendering the igoBot
You don’t have to trample on the poor victims, but I still have one more. Both 16-cores are allowed to render our well-known bot, while I measured the power consumption. I then put the whole thing into relation to the actual power consumption over the render time, because the power consumption in watts is only a snapshot, which says nothing about the real amount of energy, because the factor time is missing. And that’s exactly when it gets worse for Intel’s glow plug, but always one after the other.
Next, let’s look at the pure render time in comparison. 16 cores Intel versus 16 cores AMD. Blender version 2.80 was used and it was only rendered on the CPU. HT (Intel) resp. SMT (AMD) were of course activated (and deactivated for a counter-test).
Let us now compare the power consumption of both systems, averaged as an average value:
And now it will be really painful in your wallet, because what counts in the end is the real energy consumption to master this task. Now let’s add the time factor and compare the fun once again with the energy needed to complete the job. The Ryzen 9 3950X is faster and more economical, which ultimately translates into a little less than half the amount of energy needed. Or to put it more popularly: the Core i9-9960X consumes twice as much for the (significantly slower) completion of the same task.
What comes to the fore with both CPUs is the fact that you are much more efficient with SMT and HT, whereas the difference with the Intel CPU is even bigger. This would be even more significant without all the security patches against the side channel attacks, but you have to be fair and test the actual state, not the ideal state without patches. I don’t even want to imagine what else could have been shown here with the 65 Watt Eco mode. As a buyer of the Intel CPU, this result is already painful enough for me.
