Imac 5K performance?
on Jul 10, 2015 at 4:48:23 pm

Hello all,
long time reader here, first time poster.
So I'm looking into buying a new computer soon,
and the 5K Imac gets my attention,
but I'm wondering about it's performance:
can any of you who actually work with it day to day chime in?
I'm particularly interested in knowing
if the display doesn't take too many ressources
from the graphics card?
Does the computer respond well with for instance
After Effects or Da Vinci Resolve,
which are pretty demanding GPU wise?
What about working with FCP X?
Is the GUI responsive?

Really appreciate all your thoughts on this.
Since Apple discontinued the high end non retina 27" Imac
with the 4Gb GPU it seems like you have to get
the highest specced 5k Imac in order to get
a powerful computer from them,
but the price is quite hefty,
so, is it worth it for you?

Thanks again!

Yep it's great- screen is solid and performance good. However, that said it cannot compete with the higher end CPU/GPU options on the Mac Pro if you want ultimate firepower.

Actually, if you want "ultimate firepower" you'd have to switch to another platform.

Which platform would that be?

Interested in what you suggest suggest by switching platform? As I'm looking for advanced video data flow solutions. Moving 10's TB of data from multiple editors between continents to and from mainly FCP X users but also VFX.

[Anders Utterstrom] "Which platform would that be?"

Windows or Linux if you depend heavily on CPU bound tasks like simulations and 3D rendering - applications like that will benefit immensely from having as many fast cores in a machine as possible. For newer GPU based renderers like Octane or Furry ball, the ability to stick three or four powerful video cards in a machine can cut the process of look development and final render down from weeks to days. For editors... it probably doesn't make much difference.

Yeah, I'm not going for "ultimate firepower",
I know you can do better than Imacs for that;
just a good powerful computer
that will handle occasionally heavy jobs
but mostly light stuff.
Not that I wouldn't go higher end
if money wasn't to be considered...

Thanks!
Sure, I know the mac pro is better,
if you get at least the mid range one,
but then again, the price is also pretty higher -
if you consider you must also get a screen -
and one I'm not sure I can afford right now.
But maybe a refurb?
Also, it seems like it may get refreshed later this year,
so also waiting to see what they come up with, if anything.

used one for a couple of weeks, cutting in premiere and doing some AE - for what I was doing it was great, and it was an i7 with 16GB and a 2GB radeon? i think apparently there is an overhead to drive the display, it's maybe best to stack up the specs - but everything is worth it for that display.

I do seem to read everywhere the display is fantastic,
haven't gone out to see one yet,
but what about reflections?
On older Imacs this was definitely an issue,
but I know they've gotten better.
What was your impression?
Was it comfortable to work with
even in a well lit room?

yes it's super comfortable - it's a print density display around two feet wide on the diagonal.

Good to know that it is working out. How important is the 4 G video card vs to 2 G? My mid 11 27 inch just boots to a gray screen, so I am guessing I will be upgrading once the genius bar guys tell me its junk. What about the internal drive? They now offer a 2TB fusion drive with 128 G SSD. I use an external raid for my FCPX files. Damn, sounds like $3k is about to fly out the window.

My 5K IMac handles everything I throw at it. 6-8 K photo images open in a snap. 4K plays back beautifully and I edit with 1080P, UHD and 4K H.265 footage.

I have a fully loaded 5K iMac from back in December.

If you want to go full bore, check out my friends at FCPWorks and their system solutions.

The IMac 5K is a very good computer and the screen is gorgeous.

Facebook is the only thing that gives me an occasional spinning beach ball.

Good luck

Ultimate FCPX firepower was my implication. If you want the ultimate firepower, get the Death Star.

And since I'm still here,
another question:
what about heating?
Do the fans kick off very often/easily?
I know Imacs often heat up quickly
and then can get noisy,
but I've also become used to that,
so it's not such a big deal for me,
just curious to know if they've made progress on that front also,
especially driving that monster display!!!

Fan noise on iMac & Mac Pro is non-existent compared to most Macs I've ever used.

Agreed on the mac pro,
that thing is unbelievably quiet!
But what you say about the imac
is even more impressive,
having to drive that display
and doing it quietly, wow!

No, there is no noise.

Well, besides me blasting old Swedish punk like Ebba Grön.

Mauricio, now hit the button and buy the machine -:) Come back here, for any follow-up questions.

Spanish or Italian? M.? I'm obviously Swedish -:)

Thanks for all your answers!
great to see it's working so well for everyone,
it definitely has quieted down some of my concerns.
Now I'll wait nonetheless to see what they come up with in the fall,
as I think there are good chances for both a Mac Pro
and an Imac refresh...Well, at least I hope so,
time will tell!

The only noise you will be dealing are external chassis e.g. Thunderbolt and RAID drives.
I have a 2012 Mac Pro right beside a 2013 trust me I can make the 2013 kit louder by just turning on all the externals.

As of 3 days ago I can now comment on this thread with absolute authority in that I'm now the owner of a 5K iMac. I chose a special build with the 4 GHz Intel Core i7 and AMD Radeon R9 M295X 4096 MB.

I had been waiting for the next iteration of this well reviewed machine but here it is on my desktop working just fine. The 5k display is gorgeous and flatters everything you put on it and with the new processor FCPX rendering time has definitely speeded up.

What prompted me to buy the machine now rather than waiting for the next upgrade was that I had both a Samsung 28" UHD monitor hoping to have 4K on the cheap only to discover, due to lack of research that it would only work on newer machines than my 2012 27" iMac, so that prompted me to click the the buy button.

So the 2 screens work very well together, the Apple screen is obviously higher quality but the Samsung U28D590 is remarkably good value. At the moment my 4K acquisition and editing is limited to GoPro 4, DJI Inspire and Sony RX10 11 but it is a pretty addictive resolution and I'm hoping to upgrade my C300 to the Mk2 version in the autumn.

Likewise I pulled the trigger on a 5K iMac last week with the same specs 4 ghz i7 and the better GPU. This I mac is a really sweet machine.... and I'm about to start hammering on it with a hefty doc project using lots of different formats and codec. Here we go....

Mark and Mark,
congrats on the new machines!
Be interested in hearing from you guys once you
really start putting them through the hoops!

Those still interested, here is my test between my $5000 new MacPro (6core, D700 graphics) VS a $3000 iMac 5k (i7,4GB M295x). Very interesting results, especially in FCX! If you want the short version, the 5K iMac is faster in FCX in most tests, and in Ppro its about 90-100% performance of the MacPro depending what your doing. Also keep in mind for the money you get a gorgeous display, keyboard/mouse where the MacPro comes with the cylinder and a power cable.

Sometimes, I think back, and I wonder about my purchases. My worst purchases were my pizza box, G3, my G4 and the cube. But, they all had a purpose which I fully exploited. My best purchases were my first air and my first imac.

The new iMac 5K I bought back in December is by far my best machine. It's rock solid. But, did I enjoy my older machines, sure did! Especially the cube.
