Well, it seems there's little performance improvements according to this. So, according to this too, the new iMac still has the same heat and noise issue. Thats pretty disappointing. I could have accepted more or less the same performance as last years model if was at least going to run a bit cooler when under pressure.
Well, honestly, the results are pretty good. About 10% inrease, which is pretty nice. If anyone was expecting double performance with the M395X, they were delusional. Even in the PC world, double performance is unheard of in an evolutionary step of a gfx Card (i.e. 295x to 395x and not 295x to Titan)

Also looks like the M395 beats the M395X in some tests, which I am highly dubious about.

That doesn't sit well with the test in this thread which put the 395X about 20-25% ahead of the 395.

I agree, it helps to compare with old gen, you can have a global overview, you can see the difference between different gen or differences into each gen...
First comparing retina and non retina iMac benchmarks has not much useful point. Secondly, this thread is to decide what configuration to choose for the latest iMacs, not to ensure your past purchase is still relevant.

Hi all. I'm cross posting from #118, because it is getting out of hand:
All sorts of benchmarks are coming out as the new retina iMacs come in, but they are not standardized, and so it's impossible to compare. Here is what I have collected so far. If you can add to the information, please post, but do so with the same quality settings.
If you want any different benchmarks collected, ask and I'll add them to the list.
I will collect the results in this post.

Anyone have the benchmarks from the integrated gpu from the 21.5 inch Rimac?

Thanks!

I certainly was not expecting crazy amounts of performance increases, and I never stated any thing as such. There never are any such massive jumps these days. I stated clearly that I could have accepted even the same performance as last year if the extreme heat and noise issue was less of an problem.

Agreed. That barefears heat info sorta has me regretting the M395X now, should've stuck with the M395.
 
Yowch... look at that noise and temp! I am still wondering if the i7 is heating up the enclosure (display) and causing as much or more of an issue than the GPU. I may be delusional but I believe the best gaming setup would be the i5 + M395X (maybe even the M395 based on the results of those tests). So goes the inability to isolate the GPU from the CPU because most people are checking the boxes for both GPU&CPU if doing custom order.

REQUEST: Does anyone here on the forums have an i5+M395X? I would be willing to chip in a couple bucks to pay for games and benchmarks so we can see how it stacks up to the Barefeats tests and other users on the forums.

Thinking about it and looking at the benchmarks more, the M395X is most likely a rebrand of the M295X so the performance increase shown is likely all due to Skylake update over Broadwell (which is the chip I believe is in the 2014 5k iMac).
I have an i5+M395X. I will do a Heaven benchmark repeatedly (4-5 times or so) to see if there's any noise or throttling when I get home.

Huh? Didn't you have a suspicion that the 2015 model would be similar to the 2014 model?
I had absolutely no idea how any of the GFX cards stacked up when I ordered early on. So instead of sensibly waiting a week for reviews I decided to blindly throw money at the issue and hope for the best lol :D:D

I'm not a huge gamer so there's still hope the heat won't affect me much.

Oh ok gotch ya. Yeah I was going to say the second they announced the new models there was a very good chance they would perform the same as last years. If you have no need for a 4GB card then you might want to return it. It's going to run hotter either way, even if your watching a 1080 HD video on youtube. It will be a great computer either way but will have some quirks
 
I would love to see how much the i5 vs i7 plays into the different heat and noise with each of the current gpus.

Me too. Looks like Barefeats is tackling that next. I ordered the i7/m395 which is still processing. The i7 definitely has a bigger power draw when idle and ramped up so curious how benchmarks look and whether it makes sense to save the $250 and just go with stock high end iMac (+change to the 512ssd)
 
Still very interested in the m380 here. I am thinking of ordering the base model plus 512 ssd, and returning last years model with the m290x. Mostly because of the fusion drive not that I expect the m380 to be better, but if its underpowered I might save myself the coin as I want to keep this computer for at least 4 years.

The iMac is a beautiful machine but I'm really sorry to say that the GPU performance is simply pathetic for the cost of the machine involved.

Apple could really benefit from making this half an inch thicker and solving some of these cooling/noise issues and pack it with more power and perhaps a cut down desktop card while they're at it.

It's just so frustrating that there is no Mac option for a great graphics card as the pro is constantly behind and the iMac they keep seeming to think needs to be filled with laptop guts so it can be pointlessly thin.

:-(
 
Can we please get back on subject here. Honestly if you have an older iMac or hackintosh, I can guarantee you that no one cares. Nobody in this thread cares how much better your older iMac handles graphics at your lower resolution, or how your hackintosh with a top of the line desktop graphics card performs better than the AMD 3xx series.

The goal here is to help undecided iMac buyers help decide which configuration to purchase.


There are a lot of goals here. You're not the czar that decides.
 
I can't imagine the 395X will be that different from the 395 in terms of heat...

Unfortunately if you read the barefeats article it says the following:

"The M395X runs just as hot as the M295X. Both quickly climb from 45C to over 100C when stressed."

The design really needs to change to handle these higher end GPUs temps. You can see all the test results here:

Yea Im saying, whats the difference between these two cards besides RAM? The 395x is maybe clocked slightly higher than the 395? I don't see why heat would be that different

Ah sorry I misread your post, I'd like to know that too. Most sites only bench the high-end it would be nice to see how the m395 handles the UI along with things like Lightroom/Final Cut/Premiere etc. My thought is that the extra VRAM is more important than the clock speeds.
 
So, is it worth to spend the extra money to get the 395x for Lightroom raw image editing?

I'm still not sure!!
 
Haven't been following these graphics threads much, and a bit behind on the current state of GPUs. However, most of the reviews of GPUs seem to be around gaming performance and what-not. But that's not the only reason to get a nice GPU. Personally, I upgrade dot the 395x because I want to ensure I can comfortably drive several high-res displays. Currently, I'll only be pushing a 5k and two 2.5 Ks, but I may be upgrading my external displays at some point. When I do, I just want to ensure that everything flows fluidly, and without lag. I know that the new 5k supports two external 4k, just not sure they can both be at 60z. And that's my desire.

Anyhow, does gaming performance always correlate with diving more pixels for non gaming kinds of tasks? I seem to remember reading, number a years ago, about how workstation and gaming GPU values weren't always aligned. That some GPUs that were screamers at gaming things didn't do as good of a job with lots of pixels.

This is not something I'm asserting, just something I'd like to know. Could it be that Apple chose this line of GPUs for their ability to better support pros driving lots of pixels for work applications, instead of people trying to play games? Just wondering...?
