It was 15 minutes before closing time, I ran it on a store owned machine, and I couldn't recall the exact settings. ninja2000 ran it on a m395. I ran it on a m390 (the more inexpensively priced, 24 GB SSD version). I realize that "24 GB " has likely turned off quite a few mac aficionados, but "how much do you lose by picking the lower priced version" is a question that must be asked.
Got a tip for us?

Thanks a lot, i know enough now to get the 395
It is interesting though as AMD doesn't list a chip with 16 Compute units running at around 958mhz.
Could be a R9 M390X with half it CU's shut down and a ramped up clock speed.
Or it's an R7 370 desktop card but then used in a laptop format.
It has 16CU and around the same speed clocks.

m290: 14 compute units?
m290x: 20 compute units
m295x: 32 compute units
m370: 10 compute units (the macbook pro 15 uses this to drive a smaller screen...)
m380: ?
m390: 16 compute units
m395: 28 compute units
m395x: probably 32 compute units
Of course, the clockspeeds are over the map.
IIRC on a GCN card, there are 64 unified shaders for every compute unit, but since luxmark only reports the number of CUs, it wouldn't be prudent to speculate.
Here is a comparison between the M380, M390, M395, M395X and even the M390X (for reference), it's from the Canadian AMD site (it doesn't say much, sorry): http://products.amd.com/en-ca/compare?prod1=50&type1=Laptop Graphics&prod2=53&type2=Laptop Graphics&prod3=55&type3=Laptop Graphics&prod4=56&type4=Laptop Graphics&prod5=54&type5=Laptop Graphics
This is kinda useless comparison as it basically only lists features... it doesn't list concrete specs. Those clockspeeds are just listed as maximums and what they really are in each card is totally up in the air. It is shame that AMD itself doesn't list more detailed information. I was looking at that myself some days ago and was stoked this was the best they had on their site.
In the game-debate comparison link, they just say that the M390x is similar to the M290x. However all the rest of the data there compares the M380 to the M390 and not the M390x. Maybe there is no equivalent to the M390, so they told us about a related product the x version in that specific subsection.

You're right, there is virtually no information to be found directly from them. Sorry about that, I noticed right after posting.

Sold my late 2014 5k iMac away for a good price last spring....didn't need it, late 2012 27" is still enough for me at the moment. But if the next 5k iMac is still with AMD i just might get that one...

Unfortunately because we are talking about Apple here, this will not translate to increased performance but... TATATATATADAAA...The Thinnest iMac Ever!!!
Same question. The only graphics-intensive apps I use are Lightroom (now has GPU acceleration) and FCP X.
Any1?
Well, Adobe Programs and Final Cut Pro X make use of the GPU RAM and power of the GPU. So the more money you spend = more power = less waiting time for items to render, encode, or play back at full resolution. For the work I do (working in 4K with LUTs, RAW Photos) it is a no brainer that I get the most powerful GPU with the most RAM. If you think you'll be working with graphically intensive materials in a year or two, then yes, you need to spend the coin now to get the best performance later.
Ok, thanks for the link. For my surprise, M390 and M390X nether have True Audio DSP. So they're not a Tonga chips.. but a lot older generation GPU's. Maybe M390 is Pitcairn XT and M390X Tahiti LE...
UPDATE: that link is contradicting with this one:
http://developer.amd.com/resources/hardware-drivers/ati-catalyst-pc-vendor-id-1002-li/
According to latter link, M390X and M395 are based on same GPU. So... then both of them should be Tonga chips.

Absolutely. You're driving a lot of pixels, so doing anything remotely intensive will take advantage of the extra memory!
Has it been proven though? Somehow I don't think 4gb of vram really has any performance difference compared to 2 gb. Even the 395x probably doesn't have as much as a performance boost as having an i7 with hyper threading vs an i5.
This French website has benchmarks for old gen vs Iris Pro 6200 vs M390 vs M395X

Hi everyone! Just registered to this forum and already got a question for you all:
considering I'll be using the iMac mostly with Lightroom and perhaps a few games, do you think a 27" with i5 and m395 would be more than enough, or you suggest to upgrade to an i7 or m395x? Prices tend to get absurdly high but I don't want to have an obsolete machine in the years to come…
Thanks

Just placed an order on an i5 3,3GHz, M395. Good to hear the fans are quiet. But that temp worries me a bit, I didn't get apple care. I wonder if I should cancel my order and get the M390 instead... Has anyone run a similar test on that card?
The case on every iMac I've ever had has turned scorching hot to the touch. Never had a problem.
They'll test run the design for days on end at full load in high temperatures before release.

Indeed, the mid range 5k with the M390 seems to be a good value for it's Price tag.
But I was a little surprised, that the 4k iMac with i'ts Broadwell CPU seems to be better (CPU wise) than the i5 Skylake.
i can't translate but is the M395x better than M295x in performance and how about the fan and noise ?
