“Apple’s 5K iMacs have been extremely popular, especially with content creators, and this year’s hardware refresh packs in even more bang for the buck,” AppleInsider reports. “Externally, the 2017 iMac is basically identical to the 2015 version apart from the replacement of two Thunderbolt 2 ports, which have shifted to Thunderbolt 3 with USB-C connectors. Thunderbolt 3 is a huge step up from Thunderbolt 2, as it’s not only twice as fast at up to 40Gb/s, but can adapt to almost anything including a single 5K or two UHD 4K displays.”
“Let’s start getting into some benchmarks, starting with the the PCI SSD which received a performance boost with the redesign,” AppleInsider reports. “Speed increases are impressive, especially write performance which went from 1,217MB/s all the way to 2,126MB/s and read speeds improved from 1,981MB/s to 2,718MB/s. In fact, the new PCI-SSD’s are so fast that they maxed our preferred disk speed test from Blackmagic so we ended using AJA System test.”
“If you’re planning to edit video with Final Cut X, render using OpenCL or spend time gaming, the 2017 i7 Kaby Lake iMac with the 8GB Radeon Pro 580 provides a massive performance improvement over the previous iMac,” AppleInsider reports. “If you’re a photographer or edit video with Premiere Pro, it’s really not worth upgrading. With that said, if you’re comparing both models, the 2017 is still a better value since it now sells for $300 less in the best configuration with 32GB of RAM and a 512GB SSD. ”

MacDailyNews Take: If you can, max it out! Its useful life will likely outlive your ability to deny yourself an upgrade before you need it. Apple Mac’s TCO is unmatched.

8 bit color is 256 colors.
16 million colors in 24 bit.
10 bit color is 1.07 billion colours.
you are doing it wrong.
No, I am not.

2 people voted down math.
…but they probably voted up Hillary….
I’m not going to tell you how just obviously stupid your comment is, seeing as tRump is the one that actively recruited the “uneducated”, which you obviously are.
You know th…. oh why bother.
I think I see your mistake.
24-bit color is indeed 16.7 million total colors. That total of 24 bits has 8 bits each for the 3 colors, Red, green, and blue.
10-bits PER COLOR would give you 30 bits for color total, or 1.07 billion colors.
… you certainly know your MATH, but HE knows the technology. And the technology description of “24-bit color” is 8 bits per each of three colors (8×3=24). This is based on the old-school tech of TV colors – because the family TV was the likely screen used for a computer way back when.
Were you even BORN then?
Today we are still using the “old school” RGB per dot method (Additive color), what changed is the technology to emit and control the light. Anyway 8-bits screens or panels are really 24 bits and 10-bits are 30 bits in total, because the screen is measured as 8 or 10 bits per color and not as a total 24 or 30 bits (this is a simplification and nothing more).
Add to this some screen panels are 10 bits dithered, really 8-bits per channel “displayed at a time” but the internal processor is capable to process 10 bits of color and produce smoother gradients or color transitions.

LOL… somebody voted down math.
Math is highly over rated. 😜
A lot of people voted down math.
It had to be Firsty or Botty who down voted because math and science have a liberal bias. ROTFL
I know huh. I didn’t have to put the sarcasm tag.
Something for bottwipe.
Hey Bottwipe,
Coming back from Yucca Valley today after making a payment on a place there for my retirement, I ate some of that hybrid edible I like. The one that makes me “think”. I know you are going to latch onto that turd so I’ll just let it go.
Anyway, thinking of you and that coal dust in your nostrils. That is when you can find shift work.
I think you need a story.
he Parable of the Burning Bridge.
I was in Honor Camp. Fighting fires, stream clearance, maintaining fire breaks. It was a crisp cool Autumn night. Crystal clear, leaves rustling slightly. We were standing around the firepit in the visiting area. Maybe 12 feet across, 7 feet deep. Nice fire. Talking about the day. Thing is we were high on PCP. Marveling at the Infinite Bounty of the Universe. The wonder of life. Anyway…….. the fire was dying down.
Bummer.
That’s a drag. So I’m standing there and say, “what about the bridge”. The nice kiddie bridge across the ‘stream’ bed through the visiting area.
I was kidding of course but could see the realization that “what about the bridge”. So the next thing I know, the bridge is across the fire pit.
Simple English Botvinnik. I did not move the bridge.
Well, after the bridge caught, it dawned on people that maybe they should get away from the scene and you could watch people drift off.
Soooooooo…… the bridge was burnt.We enjoyed the PCP.
Riddle me this Batman.
Am I liable, responsible, cause of, etc the burning of the bridge. Should I have learned a lesson about it. Should I confess to a priest?
I don’t do anything special or design render video nothing but I WANT IT! lol
I know, huh.
I had mentioned how there were a number of articles I read where they had tested the iMac under full load and it thermal throttled. I mentioned it here and someone got angry and said I was full of it. There are numerous articles on the internet claiming the iMac had thermal throttling issues. As it is, the iMac can’t be overclocked, so why handicap it even more. I don’t see the point of Apple putting in a more powerful CPU and GPU if it’s going to slow down when under full load. That’s careless of Apple to build something like that. A consumer is paying for a more powerful processing and getting less than what he paid for. The tests didn’t say what the ambient temperatures were when they ran the tests so maybe that could be a problem if the ambient temperature is already high to start with.
That’s why I’m going with the iMac Pro with the claimed much better cooling and hopefully, I won’t really have to run it much under full load in case that new iMac also thermal throttles the CPU. In tests, they showed that Radeon Vega GPU kicking up fan speed under load and I hope the iMac Pro can move plenty of air. That’s a terrible design fault to have a slim-looking case that isn’t all that practical for a fully-loaded CTO iMac.
Nonsense, I just got one of these iMacs, and is smooth as butter as far as GPU intensive tasks that are optimized for Open CL. Sure, the processors don’t run top speed for prolongs periods of time, but I am at least getting 4.1GHz while rendering, and that is good enough for me.
So, the ridiculous quest for thinness forces your iMac to slow itself and this is OK with you?
Since I bought my GoPro Hero5 Black last month I’ve realised my 2010 MacBook Pro just doesn’t cut it anymore, so I have decided to wait until the iMac Pro is released then by which time I’ll have done enough overtime to afford it… and have months of gorgeous 4k footage to play with.
Snappy.
Don’t even bother.
Wait for iMac Pro and then buy it.
The 2017 iMac is using 2015 technology and just remember we are now 7 months into 2017 – 2018 is coming and iMac Pro kicks the year off at the end of 2017.
You wil not be sorry.
That is 2,522 MB/s read & 2,172 MB/s write write for iMac 2017.
Apple should have chosen (or at least allow user upgrades) a much better and cheaper disk like:
Samsung 960 PRO Series – 2TB PCIe NVMe – M.2 Internal SSD (MZ-V6P2T0BW) Sequential R/W (read/write) speeds up to 3,500/2,100 MB/s and random R/W speeds up to 440/360K IOPS, respectively.
