Indeed.
Barefeats has some indication (see Diablo III) but not enough shootouts yet...
I'll be getting my i7 with 780M later in the week. I will be testing X-Plane on it vs. my good ol' Mac Pro '08 with Radeon HD 7950.
I will share the results of real life X-Plane 10 with a H U G E amount of add-ons!

I look forward to.
Especially interested in whether there is a difference 780m/775m Alienware in the iMac, I think that in the iMac may be cutting back on the frequency.

Did you fly it yet? Very curious to see your results.

Some 3DMark11 scores there, and some Tomb Raider ones too:
(as I said in that thread, "dependable" benchmarks for real games are hard: many games don't offer benchmarking tools)

Yep.
Love my new iMac.
I did a few simple comparisons between these two Macs:
1. Mac Pro '08, 8 x 2.8 GHz, 16 GB RAM, Radeon 7950 Mac Edition 3 GB VRAM, SSD-boot, X-Plane 10 on 2nd internal HDD.
2. iMac '24, i7 3.5 Ghz (3.9 turbo), 32 GB RAM, GeForce GTX 780M 4 GB VRAM, SSD-boot including X-Plane 10.
The Mac Pro was running the first versions of Mavericks GM
The iMac the "real" GM, i.e. 13A603
I used for the comparison 1920 x 1200 resolution (as that is the monitor setup on the Mac Pro)
First of all, my real-life environment in X-Plane 10 is as follows:
- Loading the default 747-400 (with KLM livery)
- Pay-ware Schiphol Airport (EHAM)
- ZL17 photo scenery of Amsterdam
- Also loaded in this scenery: EHRD, EHEV and ZL17 photo scenery of Rotterdam, Domburg, Eindhoven, Utrecht, Enschede)
- 15 extra AI aircraft (using Morten's specialised AI aircraft)
- Worldtraffic 1.1.6 with EHAM ground routes
These settings use about 2.5 GB of VRAM.
These extra's make my X-Plane experience totally different from most online tests like Barefeats.
These are my results:
1. Daytime rendering: Mac Pro: 21 FPS, new iMac: 30 FPS.
It's obvious that the CPU was the bottleneck on the old Mac Pro. The new iMac can even up the settings quite a lot and still keep the same FPS, even at the higher resolution of the 27" iMac.
The new iMac is a huge benefit!
2. Nighttime rendering Mac Pro: 20 FPS, new iMac 19 FPS...
This one is strange. On sway or another nighttime rendering is worse on the new iMac.
I assume that GTX 780M or the drivers are to blame here.

I will be very interested in more results of X Plane 10. Have you ever used more than 3 GB of video RAM?
I am running X Plane 10 on an early Core i7 Hackintosh with a video card of 1 GB, and I am probably going to build another Hack with a GTX 780. My current Hack has 6 GB RAM, the new one will probably have 16 GB. But, I wonder if it is really necessary to have more than 8 GB.

Multiplayer. 64 player server.. High is even more than 40 fps.. lets say 40-50
yup on the gtx 780m.
its impressive High+1440p..on my friend (that has 680MX)we never get over 40fps on these settings. So still a game that is made to use all of that vRam of your gpu make the 780M superior to 680MX like 10% right?
high settings at 1440p in battles my friend get 38-40fps

The maximum amount of VRAM I have used was close to 2.9 GB. See screenshots. This is by far the most extreme scenery I can load (most extreme there is...), and thus with my favourite settings I reach around 20 FPS.
On the ol' Mac Pro I got max 15 FPS (with lower res, and slightly lower settings)
Note that texture compression is turned "ON", otherwise VRAM consumption can be double (!).
I reach that when I load "New York":
- Pay-ware KJFK, KLGA, and also freeware KEWR.
- ZL17 Photo scenery of New York
- Converted ManhattanX
- 15 extra AI aircaft (Morten's)
RAM consumption of X-Plane 10 alone can easily exceed 8 GB. If you want RAM not to be an issue, I strongly advise 16 GB RAM total.
12 GB is probably enough, but then no other app next to X-Plane 10 can use much RAM.
See my RAM consumption below too.

Hey ... thanks so much for posting these. I have an older iMac (late 2009). There's absolutely nothing wrong with it ... other than I can't fly xplane 10. I'm trying to decide whether to get a new souped-up 27" iMac ... or wait until the specs come out for the new Mac Pro. Good to see with your set-up ... that you can fly at decent frame rates.

Thanks for that info about the RAM. Will install 16 GB for sure. My research tells me that the 780 GTX is a lot more robust than the GTX 780M. What are your thoughts on this?

The "full-blown" GTX is indeed far more powerful than the mobile (M) version.
X-Plane 10 will love it, as long as your CPU is fast enough, i.e. later generation i5 / i7 Quad Core > 3 GHz.

Core i7 Haswell 3.5 Ghz teamed up with the GTX 780 should work fairly well, don't you think?

If you are interesting in BF4, have a look at the multiplayer test results...
