High-End riMac Gaming Performance

yeah let me be the first to say, I'm running these based on recommendations of others, i have no idea what they are, what they mean, how they compare, or even if it makes sense to compare them to windows machines

all i can say is that SC2 works great! ill do another run on SC2 with hd settings

R9 285 is the Tonga Chip with 1792 GCN Cores.
R9 M295X should be slightly faster or at the same level considering lower clock speed, but higher core count.

Edit. This GPUs is very ... strange.

Looking at scores, and Teraflops performance it should be as fast as R9 280X in those benchmarks.

Maybe its because of the benchmark...? I have no idea whats going on.

One thing is for sure, OSX and Drivers are bottlenecking the GPU.

I was not expecting you to be able to put any sort of game up at 5k with anything but stop-motion effects resulting... Obviously most people are going to be gaming at 1440p max, and the frame rates there are excellent.

1/3 of a desktop gtx 970 is not good buddy...
 
In 3dMark tests made in Parallels you get around 10-20% worse results, than on Windows, native.

It is for a 5K rez in an iMac. I'm very impressed at that score the OP got.
Do you know what a 970 does at even 4K rez?
Google 4K gaming and check it out.

starcraft score seems to be very good, however the low score in unigine tells a different story
 
I would only pay close attention to actual game benchmarks. Among other things, AMD and NVIDIA are known to tailor drivers to do 'tricks' to get as high a score in synthetic benchmarks as possible, often in ways that doesn't translate to real games.

And speaking of drivers, let's not forget that this card is exceedingly new and not even available for PCs yet AFAIK. New drivers will almost certainly bump performance up, especially in Windows.

You might bo on to something.

Check the Thief Score. Tonga is all about high resolution performance, as we can see in that benchmark, 1792 GCN cores with 256 Bit VRAM Bus is on par with 2048 GCN cores with 384 Bit VRAM Bus.

And R9 295X is Tonga GPU, and should be even faster than that. Even faster in higher res than GTX970. Maybe this is why, the OP got 29 FPS at 5K resolution in SC2.

That GPU really maybe a beast in comparison even with Nvidia Maxwell GPUs...

Of course, those are the scores from Windows platform.

Why would we go quiet? So far (based on these preliminary tests), the GPU is no faster than the one two years ago in the 27" iMac.

Look at my post here, with the comparison benchmark.

I'm REALLY hoping it's just OS X/drivers holding the 295 back, but so far, it's very, very unimpressive.

I want to be wrong, since I have one on order...
 
at 1440 I'm getting and average of 63fps (range 45-71)

@OP

Just curious, once you get WOW down fully, could you play with the anti-aliasing settings at 5k (e.g. turn it off completely)? I really wonder if anti-aliasing would actually add anything to image quality at such a resolution.:cool:

PS: Of course I don't expect gaming at 5k, just for kicks though ;-)

nope, I'm done taking user requests

In Windows you would get at that resolution 75 FPS on average then.

FullHD should be in 100FPS range. In OSX. Over two times faster than SC2 scored on 7970M/8970M/M290X in Windows at that resolution.

Which means:

In normal resolution you will not see benefit from it. Only at Ultra High res - over 4K.

GTX780M in Windows at FullHD gets 75 FPS, which this GPU gets on 1440p. You guys are sure that is what you get at that resolution in OSX, on that card?

I don't care about benchmarks as long as it can run the resolution seamlessly and edit video smoothly, which it can going by reviews.

I'm really hoping this where the bottleneck is occurring. I mean considering how new the card is, I would expect better performance with driver maturity.

I'm getting excited by the results so far though - very promising.

I wish we had some Cinebench 15 CPU and GPU scores to look at :)
