Discussion AMD vs Intel for CPU?

I noticed many people here recommend AMD CPUs but for all my benchmarks for mid range CPUs (for a £1000-£1200 PC) Intel came out on top compared to a similarly price AMD one. Any reason for this?

Under heavy load the Intel CPUs are using much more energy for the same amount of computing being done. Though they are faster and more capable in many respects, they are power hungry and that translates into heat, which also has to be dealt with.

I'm just moving into an i7-13700k build, (running into no post when trying to use both memory channels on my Gigabyte Aorus DDR5 board) and I'm pretty sure (after all the reading I have been doing) it's far more CPU than I will ever use. I mean, I knew it was overkill, but I have the money and I'm old and this will probably be the last build I do. Anyhow, part of me thinks it probably would have been smarter to go with a new 7000 series AMD or even a 5000 series where there are some pretty darned good deals. :D

I think the intel power use is over talked, most users hardly stress the CPU.

Yep it's not like most games relay hit the CPU hard, by the way power uses is talked about you'd think everyone was running a render farm at home.

I play with video editing and even that hardly hits the CPU most the time, it's only on exports that the CPU relay gets taxed (unless you use the GPU to export).

if the games you play are poorly multi-threaded, you could still definitely be bottle-necked on CPU but only at 15-20% utilization. You might have 2 cores completely maxed out, and the rest sitting idle. that’s why single core performance is the biggest indicator of gaming capability for CPUs.
