ExtremeTech thinks iMac Retina does 5K @ 30Hz

Media is ****ed up nowadays. Bad publicity for Apple generates a lot of clicks. It's all about ads and dollars for those sites...

Maybe the game the reviewer was playing downscaled to 30hz and the reviewer misunderstood this and assuming it runs in 30hz all the time.

Whether running in 2560 or in *unscaled* 5120, it runs at 60Hz.

Here's a 5120 screen shot attached for the record. It's way more usable that I thought it would be. Not optimal, but there's a time and a place for everything.

Again... would you mind mailing me the imac to confirm the 60hz for myself? Not that I think you're a liar. I'll be sure to send it back after I'm done ;)
 
This thread is a perfect example of what's wrong with the internet.

The title proclaims "iMac Retina operates at 30Hz when in 5K" from a source that clearly doesn't know what they're talking about. It's then regurgitated as fact by the thread creator - and thus spreading misinformation.

I feel sorry for Apple. I imagine a few people have cancelled their order because of this.

The 5K Retina iMac does NOT operate at 30Hz. It runs at 60Hz.

Phew. Rant over ;)
 
They say the GPU is limited to DisplayPort 1.2 in there article and thats where I think they came to there 30 Hz conclusion.


Sounds like they are making an educated guess based on the standard gpu driving an external panel. There's already been discussions how these are probably customized parts with proprietary connections.
 
LOL - it's 100% 60Hz folks. Seen in the flesh and used one of these and I literally did visual test to check this was the case. Simply moving the mouse around on screen is enough to tell the difference between 30 and 60Hz.

PS - the screen is amazing.
 
I don't think they would make that claim without it being true so you had better cancel.

Do you intend to run you iMac at 5k?

You're trolling right? its very easy to make a claim which is untrue - even better to do it to ***** with people and get them to cancel orders.

To be clear, its 60hz.
 
This is unacceptable! Jesus! The fail is strong in apple this year!
Thanks for sharing the link, i've just canceled my order! Ill wait for the 2nd gen, as always there's something wrong with a 1st gen.

**** The Retina 5K iMac is 60Hz. ****

The author of that article on ExtremeTech clearly should be writing articles on technology.

I'll continue to enjoy my first generation 60Hz iMac with Retina 5K display.

:cool:

Dear MacRumors forum mods. It might be a good idea to change the title of this thread as it's completely wrong and totally misleading.
 
I saw the imac retina in the apple store today and definitely 100% 60hz. Was very obvious with the mouse movement. I was also happy to see I was able to use SetResX without any kind of special administrative power and thus was able to run it at its native 5120x2880. It was very nice and easily usable for me.
 
I've tried borderlands the pre-sequel, set it to high settings and capped at 60FPS. I'd say it is 60FPS for sure as I have captured it on my iPhone w/ 60FPS mode. Really butter smooth!

No way you played Borderlands at 5k on a mobile-class GPU and got 60fps. Even 4k taxes the most powerful desktop GPUs. You were playing at a downscaled resolution.

i did not mention that i played it in 5K. it was 1440p, max i could set in the settings btw. I'm saying the display is displaying 60FPS as it should... Unless you have evidence to show that it does somehow cap at 30Hz at 5K? is that even possible?

Hahaha. My god I hope you are joking.

Edit: I see from your post history you're merely a habitual troll. Lame, not funny any more. :(

Is this about 30hz screen refresh or 30FPS and what is the difference?

The claim that the new iMac runs at 30hz is false, but anyway:

30hz means your monitor refreshes the pixels on the screen 30 times a second. This is independent of whatever some game on your computer is doing (unless you have vsync enabled and then the two happen in a logical order).

IF the iMac was 30hz (which it certainly isn't and that's indisputable fact) then the maximum fps on your computer that you'd ever notice would be 30fps, plus awful tearing most likely.

Also, even for just regular use, 30hz is awful. Originally I was running a 4k monitor at 30hz and it was a terrible experience.
 
That guy just opened a game, tried to play it at 60fps at full 5k resolution, didnt work, worked at 30-> wow its running at 30hz.

A game with smaller resolution than 5k 60hz works fine that just makes sense but that is in A GAME. Thats a whole different playing field. FPS and resolution go together. At a lower resolution much higher frame rates are possible and the other way around really high resolution cant drive a high FPS most of the time if you want it you need a really good GPU, "gaming" GPU. (In Game)

The iMac is running 5k (best for retina) at 60hz in OSX
 
More importantly, that tweet quotes his discussion with Cameron Rogers, who is likely to know. He says it's two DP1.2 channels running 60Hz (unlike what Anandtech is guessing).

Cameron Rogers' address is 3 Infinite Loop, Cupertino. OK; great credentials, but, the info about two DP 1.2 channels from the GPU to the display came from Jeremy Brown, a fellow in Pennsylvania whose credentials are unknown.

How did this guy from PA come by this interesting information when it's not available to anyone else and not stated publicly by Apple?
