Any one please share your upgrade experience?
How much performance benefit we will get?
I am a game programmer and working with Unity game engine and xCode in combination daily.
what kind of boost I will get after upgrade? I read all messages exist over this thread.

The 2012 series came with three options 2.7 or 2.9 GHz (Core i5) or 3.1 GHz (Core i7)
Depending on your applications a single threaded app won't see much improvement, a multi-threaded app will see the most! As you can compare here:
To get a better idea if its worth it for your workflow review your apps to see which ones are multithreaded, then figure out what actions you perform that consumes the most time. Then you should be able to extrapolate if given the needed work, costs and risks of damage is worth the effort. As an example is 10 minutes of time waiting for an image to convert from one file type to another going to benefit you? One or two files likely not, hundreds for sure!
I'm a photographer so my needs are a bit different from a game developer,
But I'm sure this is not the best system for that as you need a collection of different skills between the coding you need the graphics (drawing & animation). All of these really require a more powerful system as well as a larger display to work off of if you are a serious developer for Mac games. IF you are doing iOS gaming then you might be able to work in the smaller screen but I'm sure you'll want more power.

@danj thank you sir for your reply -- if I consider current cost for the processor then its around $160 so rather than upgrade I required to go for new m1 or m2 based system because more upgrades not much worth for the future.
@siddharth3322 - So tell me what is the difference between this series iMac's i5 and i7 chips? Just the slight improvement in the clocking speed! And then there is the 4 cores (threads) vs Hyper Threading which gives you upto 8 virtual threads!
So are your applications able to leverage these higher threads?? Most desktop apps don't and the few that do only leverage them during a given task! Like compiling code or rendering a video.
Intels chips don't offer core/thread partitioning so you can't control which concurrent app is using so if you think you can compile in background while you are working on something else forget it! All you'll get is the foreground lag which is a big distraction!
How about getting a used Mac Mini! Using it as your compile station! That would be a cheaper and better option! I saw a i7 for $210 the other day!
Using an Ethernet connection you can control it from your iMac (the mini is headless). Thats how I started on my photo editing! Before I got a 2013 MacPro.
@danj Basically I was running Unity, different adobe products and filmora 11 for my daily tasks and by profession I am mobile game developer.
can you able to share any video link which show setup of macmini parallel processing with imac?
This will be crazy for me :)
@siddharth3322 - Give this a read Apple Remote Desktop User Guide
Not much to see as its all within your iMac's screen! Think like how you see an externally connected HD so you move your work over to it (or use a shared NAS drive) so you remove the local iMac's file I/O for this task.
Then using the remote desktop you run the Mac Mini's apps from it. So the window to the Mac Mini is where you launch the app access the local files and Bam! Off it goes leaving your iMac for something else!

To start off which system you have will make a big difference on what is possible!
As an example: If you have iMac i5 2.7GHz system the CPU is soldered to the logic board and would require a full logic board swap out!
If you have iMac i5 2.9GHz system then you can replace the CPU chip alone! But you are limited to what Apple offered iMac i7 3.1GHz system.
Now while the iMac i5 2.9GHz system only needs a chip is the performance improvement worth it? Is the risk of damaging the system to high? Just opening the system is tricky! Many people damage the display in the process as its not easy!
Frankly, if you need performance for serious game programing this is not the best system. I would go with a 4.2 GHz Core i7 (I7-7700K), 3.6 GHz Core i9 (I9-9900K) or 3.2 GHz Apple M1/M2 system if your applications support Apples processor.
Maybe you should look as a laptop system using an external display for now like a 13" MacBook Pro 3.2 GHz Apple M1/3.49 GHz Apple M2
or wait a bit as its likely the 24" system will get the expected M2 upgrade or a more Pro/Max version iMac or Mac Mini/Mac Studio system

@danj Thank you for your reply :)
I have this model of iMac Late 2012: 2.7 GHz Quad-Core Intel Core i5
I have already opened my iMac 2 times, and checked what processor exist, its i5-3330S, as like normal PC processor.
So that I considered it for the upgrade and round $120 to $150, I will found processor from the market.
As per support, it will support i7 3770s processor.
I have already upgraded with 1TB SSD and 16GB RAM within my iMac and I don't have performance related issue.
To make it work more better, Is it worth to spend more for processor?

I converted your question into its own as you had dropped it in someone else's question which is a different system, so all of the examples I posted above don't apply!
