Blender benchmark shows AMD in front of Intel when it comes to CPU energy consumption

The never ending (although silent) battle between AMD and Intel continues, and will probably go on for a very, very long time. Going blow for blow doesn’t seem to suffice for any of the competitors.

With that in mind, a new Blender benchmark graph slightly shook the Windows community as it shows the total energy used by both Intel and AMD CPU‘s for a specific task.

CPU battle: What processors use more energy? AMD or Intel?

Here’s the OP’s screenshot:CPU energy usageThis info quickly filled the forums with controversy, as AMD and Intel fans debate the use scenarios for certain CPU‘s and how could this new benchmark results affect them.

Here’s what one user is saying:

I think in specific use cases this could be a superior benchmark. I’d imagine server owners in particular would like this benchmark, as it shows a realistic estimate of consumption vs. finishing a task at hand.

While this is half true, you’ll have to understand a couple more things to get the big picture:

Servers are sold in large part on energy per task, but this benchmark here is somewhat misleading because you can decrease the energy per unit of work by decreasing total performance (since power consumption increases faster than clockspeed)

Don’t forget that despite a very high efficiency, ARM CPUs haven’t had much success in the server world.

This somewhat surprising result has it’s rooted in the manufacturing process. While most of the CPUs from Intel are 10 nm or above, AMD CPUs are working with 7 nm processors for a while now.

Basically, that means that AMD is using smaller transistors and packing more stuff into the same place/smaller place. This leads to higher core count, lower heat/power consumption, and higher clock speeds.

If these results will have an impact in the future of CPU manufacturing or not, it remains to be seen.
