#Can you upgrade memory in imac 5k series#

The Radeon R9 M200 series uses the same Graphics Core Next (GCN) architecture as AMD's other premium graphics processors. If you plan on doing a lot of graphically intensive tasks, or are worried about paying the 'Retina Tax', you'll want to consider paying for the more powerful graphics processor. For an extra $250, you can upgrade to a Radeon R9 M295X with 4GB of GDDR5. It also sports AMD's Radeon R9 M290X with 2GB of type 5 double data rate graphics RAM (GDDR5). For everyone else, a quad-core i5 processor clocked at the stock speeds is plenty fast for whatever you might be doing. If you plan to be doing a lot of data transformation or encoding or performing other tasks, consider bumping up the processor. If you prefer, you can spend $250 more for an even faster 4.0 GHz Intel Core i7 processor. Like most of the other iMacs, this one is a quad-core i5 chip, but it's a bit faster: 3.5 GHz.

The Retina 5K iMac comes equipped with a variation on the fourth-generation Intel Core processor used throughout Apple's other consumer Mac hardware. The result is a display that fills your field of vision with pixels so small you really can't see them, and so good you can see the images they produce with stunning depth and clarity.ДЇor designers, photographers, videographers, creatives in general, and those for whom display really, truly matters, this is the desktop Retina you've been waiting for. It's also what makes it possible - both in terms of keeping heat down and keeping it thin enough to fit inside the 5mm iMac casing. That lets the Retina 5K iMac hit the same brightness levels as previous generations, but at 30% less power. There are also new, even more power efficient light-emitting diodes (LED) used for the backlight. Apple says they individually color-calibrate each of the displays as well. Retina iPad innovations make an appearance in the Retina 5K iMac display as well, including an organic passivation architecture that reduces pixel signal crosstalk and improves color accuracy, consistency, and uniformity. The process makes for brighter whites and deeper blacks, both straight on and, thanks to a new compensation film, from the sides as well. Part of that is density, and part of that is quality.ДЄll those pixels are photographically aligned as well, down to the liquid-crystal molecules, just like with the iPhone 6. That's what lets it maintain uniform brightness and a consistent refresh rate.Д®very word, every button, every photo and frame of video looks pretty much perfect. Apple says that lets them charge each one of those 14 million pixels faster, and keep the charged longer.

The Retina 5K iMac use an oxide-based thin-film-transistor liquid-crystal display (TFT LCD).

While Apple pixel doubles interface, they leave photos and video at 1:1, so you can see up to 4K images and frames at full size and still have room left over for tools and palettes.ДЄnd all of it - every string of text, every button, every photo and frame of video - looks pretty much perfect.

From left to right: the original 1984 Mac, 1080p TV, the standard resolution iMac, 4K UHD TV (2160p), and the Retina 5K iMac.ДЄll those pixels make for a great looking display, but they also make for an incredibly usable display, especially for photo and video editing. Here's how the pixel size compares to previous generation Macs and standard display sizes. That lets them work around the existing limitations and ship 5K at 60 Hz now, today.

They're taking two 20 Gbit/s high bitrate 2 (HBR2) DisplayPort 1.2 streams and fusing them together for 40 Gbit/s of bandwidth on single chip. Some vendors are going to try and dual-link Thunderbolt 2 buses so each can drive half of an external 5K display, but that sounds like a hack, and could well 'tear' down the middle when you scroll.ДЄpple is doing it internally with a custom timing controller (TCON). However, it's only shipping as part of Intel's Skylake architecture - the one after the Broadwell architecture they're still struggling to ship - sometime next year. Thunderbolt 3, which supports DisplayPort 1.3 at up to 40 Gbits/s, will be able to handle 5K. Thunderbolt 2, which supports DisplayPort 1.2 at up to 20 Gbit/s, maxes out at 4K. That Apple was able to do it now is even more impressive. The Retina 5K iMac has a panel that's around 218 ppi, and measures 5120x2880. 5K is the industry term for a display that has roughly 5,000 horizontal pixels.

Retina is Apple's marketing term for pixels so dense they disappear at normal viewing distances. The Retina 5K display is such an important feature that it's right there in the name.
