Best CPU for UF: i7 or Ryzen?

Quite spectacular! I'm curious what times people with those 24-core M2 Ultra chips would get.

Hi Frederik,
Yes, but it's very expansive Btw I tried again now and the render time is still around 1.34 minutes, I have several programs open.
I am very happy because I decided to get the i7 14700K precisely to speed up the fractal calculation, taking into consideration that I have a 4K monitor so I wanted a fast processor without compromises.
I assembled it all myself I bought the components and assembled it, the case is not compatible because the heatsink hits the RAM and therefore I had to put the front fans on top and the heatsink in front, unfortunately I bought the case years ago and the Ram Viper Venom are tall, this is the composition:

CPU : I7-14700K, 3.4 ghz up to 5.6ghz raptor lake refresh 20 cores 16 threads
Motherboard: MSI Z790-A MAX PRO WIFI-7 DDR5
Video Card: Asus Geforce RTX 4070 Dual EVO OC 12GB
RAM: Patriot Viper Venom 32GB (2X16) 6800 mh/z, DDR5
SSD 1: Ediloca EN870 SSD 1TB PCIe Gen4, NVMe M.2 2280, up to 7450 MB/s, dynamic SLC cache
SSD 2: Ediloca EN870 SSD 2TB PCIe Gen4, NVMe M.2 2280, up to 7450 MB/s, dynamic SLC cache
Liquid heatsink: ARCTIC Liquid Freezer II 240 A-RGB
Power supply: Seasonic G12-GC 750W 80+ Gold
Case: Gamemax Draco NEW 4 ARGB fans (I had to remove a fan inserting the heatsink from the front)

Hello everyone, longtime UF user, wanted to share my own results of the benchmark test since I finally replaced my ancient i7-6700 a couple weeks ago.

I did have my browser open to Twitch and Discord running, but that's it. The CPU temp didn't get above 82.4c and it was audible, but I'm impressed at what this little machine can do, so I can't complain.

My new pc is a Minipc called the UM780 XTX by Minisforum.
CPU: Ryzen 7 7840HS (8/16)(5.1MHz Boost)
GPU: Radeon 780m iGPU (8GB vram)
Memory: Crucial 32GB at DDR5-5600MHz
Storage: Kingston 1TB PCIe4 NVMe

I forgot to test my old pc but I know it would have taken at least an hour to render the benchmark and sound like a jet trying to take off.

HI,
An update, the i7 14700K is a very good CPU, I am satisfied with the purchase, but it has a problem and that is that it heats up a lot, 20 cores and 28 threads heat up a lot and the CPU under load during rendering easily reaches 97 degrees.
I have to tidy up the airflow because I have to turn two fans, but I managed to gain 7 degrees already with this configuration, however the calculation time increases by 6 seconds.
So the i7 14700K is a CPU that has an excellent quality-price ratio and performance, but the temperature under load must absolutely be taken into consideration, because INTEL has put on the market a CPU that heats up like hell fire

This is the new test with the right temperatures :

Ciao

I did the test again, it now took 1.36 minutes, so the performance always seems stable, it can vary from 1.33 to 1.40 minutes.
I lowered the temperatures of the i7 14700K only by selecting BOXED COOLER in the BIOS, the temperatures are lowered however the performance in the calculation rises from 1.32/34 to 1.36/40.

Ciao

Last update, I turned the heatsink fans to improve the airflow and in the BIOS I put boxed cooler instead of water cooler, today I did the test again after turning the fans and the performance seems the same but the temperatures are much better, now under load there are only 2 cores that reached 85 but almost all the others are around 70°, now it's perfect.
Hello everyone and have a good weekend

I'm really curious what the newest many-core Apple Silicon CPUs would do with this benchmark.
