The system I started with:
Mid 2011 iMac 27" | Memory | 8GB 1333MHz DDR3 | | HDD | 2.7GHz 1TB (7200 rpm) | | Graphics | 2.7GHz AMD Radeon HD 6770M 512MB | | Processor | Intel Core i5 2.7GHz |
The system I currently have (only changes listed):
| Memory | 32GB 1333MHz DDR3 | | HDD | 4.0TB (5900 rpm) SSHD Solid State Hybrid Drive |
The System I want
| SSD | 120GB 6G SSD Optical Bay Hard Drive Replacement | | Graphics | Mid 2011 iMac 27" Radeon HD 6970M 2Gb Graphics Card | | Processor | ...? |
(SSD is OWC 120GB SSD)
I'm not as impressed with the HDD as I thought I would be. It is way better, but it is also way more than I need. I have just under 40GB of consumed storage on my system (i.e. currently 3.96TB available), so with the 120GB I can make a 60GB partition for the entire system (startup, apps, files), and another 60GB partition for another drive (storage, OS, whatever). The 4TB HDD will be for deep storage, should I ever need it.
I am confident the GPU upgrade will work. Apple also has technical specs stating that the graphics are "Configurable to AMD Radeon HD 6970M with 2GB GDDR5".
The processor is where I'm having trouble. Hardware is not my schtick, and there are endless feeds talking about various processors, and whether or not they work.
One person might say that "You can only use an
i7 core Apple offers as a OEM upgrade or you'll have firmware problems."
Another person might say that "they're using a "regluar
i7-2600" and having no problems.
But which is it!? Will any old processor do?
From there, I've narrowed it down to five
Intel Core i7 Processors (all five compared on same page after links):
... Here is a one-page comparison of all five ...
But from here, I really don't know what any of it means. Bigger numbers often mean better (more cores, higher processor frequency, more memory, faster speeds, etc), but this isn't always the case.
They are all within
0.2GHz, which is hardly noticeable or worth splitting hairs over. Same number of cores. Same cache. Same max memory. Same package (ignoring
LGA1155). And the rest is basically identical between them, with the occasional differences that I likely don't understand.
One standout difference for the
3770 series are that they both have lower
Thermal Design Power, which will help with internal cooling and fan noise. BUT, the same series is also the only one without
Intel Fast Memory Access, which sounds pretty great!
On top of not being able to adequately differentiate them, I wouldn't know if any of these processors is/is not compatible with the graphics card and other components I've set up, or if they'll sun with my current OS.
Just to recap, the hardware:
| Memory | 32GB 1333MHz DDR3 | | HDD | 4.0TB SSHD Solid State Hybrid Drive | | Graphics | Radeon HD 6970M 2Gb Graphics Card | | SSD | 120GB 6G SSD | | | | | OS | macOS Sierra (10.12.1) |
Can You Help Me?
Can any one of these processors be used for my upgrade? Thus making the real deciding factor the features, cost and availability?
Or are only some of them suitable candidates? Which ones? Why?
If the first is true (any will work), is any particular processor more renowned than the others? I'm trying to stay away from opinions for this question, but maybe one or two of them are known to be industry go-to.
