680MX Benchmarks please

To note: The difference between Need For Speed: Most Wanted with and without an overclock (285/425) is quite staggering at 2560x1440. Whereas the framerate would drop into the 30s when doing burnouts with most settings on (not super sampling) at stock clocks, the frame-rate sticks pretty close to 60fps with the overclock.

There's no question in my mind: The 680MX GTX is a serious overclocking beast.
 
Hey William, can you FRAPP that game, with and without overclocking, get a precise average number to compare? For me overclocking in Planetside 2 was giving me only an extra 5 frames per second average, 38-43fps, but was increasing the GPU temp by 8 - 9 degrees.

I was using FRAPS. The difference was unbelievable. I couldn't quite believe it, actually.
 
Crysis 3 Configuration and FPS

Crysis 3 really stresses the GTX680MX... a lot!
When setting everything on high (with +285/+425 oc) I get 15fps.
With the Nvidia recommended settings (via the Nvidia experience) that actually sets almost everything to low/off and OC I can get 59fps but with significant drops in some action scenes. However to my eyes, there is no noticeable difference in graphics between "all high" and "all low". The game looks stunning either way!

The issue is that while I use Lubbo's fan control @ 2500/2600 rpm, the temperature goes over 86 degrees which troubles me a lot. What configuration do you use (game config/overclock settings) and what fps and temps do you get?

I wonder what positive effect (if any) a deskfan, pointed at the back of an iMac, would have during gaming.

None. The dispel of heat is to come from inside to the outside, blowing air into the device would only counteract the fans trying to dispel the heat in the first instance.

You only get 15fps on Crysis 3 with settings on high (and overclocked)? What drivers are you using? That's not right.

Use 250/375 max for Crysis 3 (285/425 gives a minimal difference, but more heat...not worth it). I've said this a dozen times, but I'll say it again. Don't use AA in 1440p in newer, demanding games...period. :) That's why you're getting 15fps. If you want to use AA and 1440p, you shouldn't have bought the iMac. Then you'll gonna need GFX Titan or a SLI rig.

So i'd be curious what max temperatures most people are getting (without overclocking and without Lubbo's) who have the Serial ATA Drive and the Fusion Drive. I have the Serial ATA and my max temperature without overclocking is 85. With overclocking (285/425) 94 degrees.

I've never overclocked my 680MX and I have the iMac with the 1TB Fusion Drive. I've seen my GPU hit 84 degrees with standard fan settings while plating a few modern games (Bioshock Infinite, Battlefield 3 and Tomb Raider). I was playing around in the CPU-intensive GTA IV the other day and I saw that my CPU was 93 degrees so I disabled Turbo Boost by limiting my maximum CPU speed to 99% in Windows. Since then, both the CPU and the GPU were around 80 degrees while playing. I had a look at what my fan was running at during those temperatures and it was about 1600rpm I think. I've tried setting it to 1800rpm and I shaved a few more degrees off but I'm not sure that I really need to do that.
 
I keep turning off turbo boost and yet there is no difference in my GPU temps. Could it be a windows 8 vs 7 issue, it works in 8 but not 7? I just find it curious.
 
Picked up Need For Speed: Most Wanted yesterday, and my goodness does it pummel the graphics card in our iMacs. 2560x1440 is only attainable at 60fps with a lot of turning down of options, and even then it dips into the high-40s-to-low-50s when there's a lot of tire smoke on screen.

But my goodness does it look gorgeous! Ambient occlusion is astonishing in this game. Just... awesome.

Overclocking really helps here, people! I went with a conservative overclock of 225/350 and it helps maintain 60fps, but don't expect 60fps with everything turned on. I'm not sure anything out there could do it!

I want to get into playing some games on My computer.

I haven't games since Half Life 2 and that was on a PC. What do I need , I'm a beginner here. I usually play games on My PS3, but just bought a new imac and wouldn't mind trying out some demos even.

Also what controller do you guys use? Can I use my PS3 controller to play?

thanks
 
Since this is the benchmark thread, check out these results for a 285/425 overclock in PassMark.

i7 3.4Ghz, 32GB RAM. 314.22 drivers.

Faster than a desktop 680GTX overall. :D

I only have the trial version of PassMark, but here are my results for the GPU. I used the iMac late 2012 i7 680mx benchmark downloaded from PassMark. As a comparison I downloaded from PassMark two benchmarks for computers with the same CPU (i5 and an i7) and a geforce GTX 680 (listed as a generic intel core...) The "This computer" is my iMac overclocked at 285/425. So in this comparison at least, the overclocked 680mx is not coming close to the desktop 680 GTX.

At that overclock 680MX is performance-wise between GTX670 and GTX680 at stock speed, but overclocked dekstop cards will obviously win out...
Btw., the summer heat finally arrived here, and I noticed the iMac got a few degrees hotter during gaming. So I compared 285/425 vs 250/375 performance-wise. I've only tested Crysis 2 and Far Cry 3 so far, but the difference was about 1-2 fps (framerate around 40-50). Possibly 250/375 is a sweetspot in terms of performance vs. heat/power consumption. Judging from these cases anything over 250/375 just seems like unecessary strain on the GPU and iMac overall. Maybe other games might behave differently though...

We don't know if those PassMark profiles you downloaded were from overclocked systems, though... That may well be a 680GTX overclocked, or an overclocked processor... or a combination of the two.
 
In case anyone's interested I played a lot of Metro: Last Light over the weekend, everything maxed apart from AA with 250/375 OC. Averaged around 30FPS, maybe a bit higher, much better performance than Metro 2033 on similar settings. I've been a console gamer for years, so although I love the smoothness of 60fps, 30fps suits me just fine.

I am also finding the game to be much more enjoyable than 2033, which I started but kind of got bored of.
 
Yes 680MX is a very good card, but 30fps doesn't cut it IMO. A steady 60fps makes for a completely superior experience. (Not to mention 120hz screens and 80+ fps.) Looking forward to see what Nvidia is able to do with the Maxwell architecture. 6-7 year old games like STALKER and Crysis still have relatively low framerates in 1440p with high gfx settings.

I just tested my 2012 iMac with 680mx and it scored a whopping 15556 on 3DMark Vantage Extreme! It beats out a AMD 7950, and is almost, by a few points, at the level of an AMD 7970. It's, with a base overclock, basically a 660ti, and with a slight over clock a desktop 670. Beast of a card! :)

That may be, but assuming most people over-clock, doesn't that make your point somewhat moot?

Looking at all the high end cards, http://www.videocardbenchmark.net/high_end_gpus.html the 680mx is #10 on the list, not bad. (And for me personally having a 5770 (#78 on the list) in my old Mac Pro circa 2006, this iMac is a big upgrade.) There really isn't a huge leap in performance until you reach the top of the list with the Titan, though the 680 is a fairly big leap as well.

Part of me kind of wishes I knew about the 680 coming out for the mac before I bought the iMac, I just might have opted for a mac pro or a used mac pro.

Titan on a mac? Now that would be cool.

Question, the Nvidia control panel, I just left everything on the default. Does anyone have suggestions as to tweaks / adjustments to the settings they believe are necessary for performance boosts or better gameplay? Thanks.
