Is it save to upgrade to i9?
I have an iMac Retina 5K, 27“, 2019 with a 3.7GHz i5 (and a Radeon 580X with 8GB of memory). I‘ll be upgrading it‘s internal hard drives soon.
When the iMac is open I could upgrade the CPU to an i9-9900k. But is it ok? Is the cooling sufficient for the i9? Does the main board deliver enough power?
I saw a video on youtube but that doesn‘t imply that it‘s ok.
So, I replaced the internal blade by a 970 EVO NVMe M.2 (1TB) which I used in an external case for some time. Additionally I replaced the internal hard disk by a MX500 (2TB) SSD. Again, I used it in an external case for a while.
Finally I replaced the i5-9600K by an i9-9900K. Both have a TDP of 95W.
Everything is working. After watching some YouTube video I was frightened a bit on replacing the CPU, but I did it.
Easier than I expected. The WiFi part on my board is different compared to the board in the instructions, but no problem.
Replacing the CPU was not that complicated. I’m writing this answer on that pimped up Mac. So,
The performance comparison: iMac (27-inch Retina Early 2019) vs iMac (27-inch Retina Early 2019)
Basically, the i5 is in GeekBench: v5/cpu/840724 and the i9: v5/cpu/5685935
Это хороший вопрос?
Hi, which stepping does your i9 have? Srels or srg19
$ sysctl -a | grep "machdep.cpu.stepping"
