hello, Replacing the Processor intel i3 intel xeon X3470. I found this video https://www.youtube.com/watch?v=Aqd3lii0… for me is this: http://s29.postimg.org/9xrmccidj/Screen_… who knows how to do that properly seen imac processor? best regards Leo
Here’s a user submitted guide on how he did it: Upgrade iMac Intel Core i3 CPU to Core i7. Just to be clear here the GeekBench test tool does not correctly identify the CPU. It shows up as a Xenon because the instruction set is 64bit. There is no Xenon upgrade chip for this system only the i5 or i7 (most people going to the i7 chip).
Because of EFI (driver) problems you can not just stick any old Intel CPU in an Apple box. So if you have the lesser CPU of your model run you could conceivably upgrade to the fastest OEM version by either replacing the CPU from a damaged unit (if your model has a removable CPU - not all do) or replacing the entire logic board. Either is a very advanced DIY project (not a place to begin DIY computer upgrading) requiring you to completely disassemble then reassemble the entire machine. If this answer is acceptable please remember to return and mark it.
I performed this replacement on my iMac11,3 2010 27" A1312, and “upgraded” to a X3470. The results were unexpectedly POOR. In fact, the machine operated SLOWER than with the i3-550. After experiencing this, it seemed that the appropriate upgrade path was the recommended one. I bought the i7-870 chip and immediately saw the performance gain I had hoped for. Here are my Geekbench 4 metrics for an iMac11,3 Mid-2010 27", running macOS 10.13.6, with 16Gb RAM on a 1Tb Samsung 850 EVO SSD. i3-550: Single-core: 2419, Multi-core 5016 x3470: Single-core: 1238, Multi-core 4180 i7-870: Single-core: 2893, Multi-core 9324 While the specs suggest the x3470 to be superior silicon, my experience with a simple 1 for 1 for 1 swap demonstrated a significant reduction in performance. The Single-core index helps explain why my iMac became sluggish, but doesn’t explain why things slowed. I bought the i7-870 on eBay for ~ $25… and fully appreciate the maximum performance this older machine can still deliver.
but what about 21.5 2010? can i replace my i3 530 to Xeon l3426?
