please run some intense gpu like video editing or the easiest way a gpu game and tell us how far the temperature is goind and how about fan noise
i said game because it is the fastest way..i think in about 5 min we know if they resolve the M295X problems or not

My Late 2015 iMac 5K with the M395X arrived today.

4.0GHz quad-core Intel Core i7, Turbo Boost up to 4.2GHz
32GB 1867MHz DDR3 SDRAM - two 4GB
3TB Fusion Drive
AMD Radeon R9 M395X with 4GB video memory

And the tests so far:
  • BlackMagic disk speed: 662MB/s write, 1833MB/s read.
  • Cinebench R15: 103 FPS OpenGL, 872 cb CPU
Edit to add: results vary between 103 and 110 FPS, and 830 and 880 cb.

Really haven't got time to install and run a game.

I ran the CPU test 2 times in a row and there was noticeable fan noise.

I then ran the GPU test 3 times in a row and there was no fan noise.

500 GB SSD test results on a 4GHz i7 8GbDDR3 (waiting for 32Gb to be delivered) AMD M395X 4GB

Oh wow! That's what I have coming next week. Those are truly insane numbers. The SSD benchmark just about quadruples what I get with my Samsung 512Gb SSD in my 1st gen 2012 rMBP! And my laptop still feels like a speed demon 3 years later...

Glad you were able to confirm that the new iMac has the same pcie SSD as the 2015 MBP. Thanks for testing and uploading!

My Cinebench R15 results are similar: 106 FPS OpenGL / 862 cb CPU
The keyboard is fine but I ended up switching back to my standard with numeric keypad.
I did find that I couldn't boot into Recovery mode using the new keyboard but could with my old one.
I also like the longer key throw on the numeric keyboard.
The mouse is an improvement as it's a bit heavier and for me that's an improvement.
Having run Lightroom 6 a bit, it is a very satisfying experience.
Not hearing any fan noise whatsoever. YMMV since I'm 62!
Here's some temps, w/not much activity, shown in centigrade from iStat:
