The inch iMac with Retina 5K display is designed with the following features to reduce its environmental impact: 4. Compare all Mac models. Storage 1. Video Support and Camera. Stereo speakers Studio-quality three-mic array with high signal-to-noise ratio and directional beamforming 3.
Connections and Expansion. While both the standard glass and nano-texture glass options of iMac are engineered for extremely low reflectivity, it helps to consider your work environment when deciding which one is right for you. Typical matte displays have a coating added to their surface that scatters light. However, these coatings lower contrast while producing unwanted haze and sparkle.
The nano-texture on iMac is actually etched into the glass at the nanometer level. The result is a screen with beautiful image quality that maintains contrast while scattering light to reduce glare to the barest minimum.
The processor orchestrates all the tasks performed by the hardware and software that make up your iMac. So the more powerful your processor, the faster your iMac will get things done. With the standard 8-core Intel Core i7 processor with Turbo Boost up to 5. And it takes advantage of Hyper-Threading, a technology that kicks in when the processor is handling several big jobs at the same time. Upgrading to the core Intel Core i9 processor will take performance to an extreme level.
With 10 cores running at 3. The more memory you choose, the more apps you can run simultaneously with a higher rate of performance. More memory RAM increases performance and enables your iMac to perform better and at a higher speed.
The standard memory configuration is perfect for day-to-day tasks such as email, word processing, and web surfing, as well as complex tasks such as photo editing, creating illustrations, or building presentations. For optimal memory performance when installing additional memory, match memory vendor, capacity and speed. The discrete GPU delivers fast graphics performance, accelerating tasks like photo editing, 3D workflows, and game development. For faster performance and more graphics compute power, upgrade to the Radeon Pro , which features 36 compute units paired with 8GB of GDDR6 memory.
For ultimate performance in graphics-intensive workflows, such as developing 3D content, editing videos with complex effects, or designing high-resolution textures in games, the new Radeon Pro XT graphics option will offer a huge leap in graphics performance and productivity by offering 40 compute units and 16GB of GDDR6 memory.

Follow the excellent iFixit guides to remove these items. Not mentioned in the guide is that you have to remove the IR sitting in back of the front Apple logo before you can remove the motherboard.
Flip over motherboard, gently remove 4 x Torx 8 heatsink screws on the bottom not the big Phillips screws on the top. Use Arctic Silver thermal compound remover and preparation solutions to get rid of factory compound. Note arrow on CPU bottom left in picture. New CPU must be installed in the same orientation. Apply Arctic Silver thermal compound with finger covered in plastic. Spread evenly on CPU only.
Guide is here - How to Apply Thermal Paste. More than 5 years later - now running High Sierra More than 6 years later - now running Mojave Dark Mode makes the upgrade worth it. It will barely run and the experience is terrible. After Mojave installation, your colours will be inverted. Cancel: I did not complete this guide. Badges: Ok a word of caution about doing this. I installed an i7 in my 27" i3 iMac and the system works, it reports the correct stats for the i7 but the cpu fan runs at high speed from boot.
I've researched a number of forums and found no way to resolve this, I also know there are a number of people with the same problem. So either I screwed up my logic board or it just doesn't like the i7 processor. It's the correct processor that people have used the i7
