Macbook Pro 15inch 2011 ATI 6750m Game Benchmarks

The 6750 is a lot faster (nearly doubled), but not just faster, the 6490 has "just" 256 MB Video RAM, this can be a huge Problem in Modern Games.
Here is something about the 6490M

Did you overclock your card ? I did the same test and only got 1531 points...well and i overclocked the card a bit. My temps were at 82°C...
yes. 750/925.
also, I'm getting a strong suspicion that the PSU supplied with these MBP's provides insufficient power to the system. I've noticed that when I run Crysis Warhead, I actually *lose* battery power, even when plugged into the wall.
WTF? Can these MBP's not handle the GPU and CPU put under load?
(Note: I've never had any game or OS crash; only the battery charge going in and out)
!amd!
If you've only had a Mac with an Nvidia GPU, you'll be suprised to know that AMD releases driver updates every single month. I've been getting that with my 5xxx series card (5870) for a year now, but I wouldn't bet on huge frame rate improvements.

When you overclock the GPU with MSI afterburn, does the clock stay that way forever? does the GPU automatically throttles the frequency down when the GPU is not used?
I think it will be dangerous to overclock if the clocks will stay at high speed all the time, right?

The clocks are dynamically changing as far as i know, they reach their maximum in graphics intensive applications and get lowered once you get back to the desktop. They get as low as 150mhz
I experienced the insufficient power supply issue too by the way. Despite having my mac plugged in, the battery slowly loosed power when i play games.
Question now is, is this something that can be fixed by a new ac cable or is a completely revamped macbook necessary ?
it throttles down. it shows you right in MSI Afterburner.
you can use GPU-Z if you need further confirmation.
The 85W adapter provided does not give sufficient power under heavy usage. Only hope is that Apple uses stronger adapters next revision.
EDIT: Notebookjournal.de did a stress test as part of their review and under load the MBP uses 87W.

Me three. Crysis and Starcraft 2.
Oh well, after like 2 hours, it was still at like 95%, so it's really not that critical. Unless you're planning on gaming for 50 hours straight. Although it does make calibrating the battery slightly more difficult, as it needs to rest for two hours fully charged before unplugging.
I see.
and I agree that it's not an issue...but I find it a little troubling that Apple would release these machines without adequate power supplies.
I think I'm going to call Apple about this tomorrow. It's easily reproducible. Does Apple sell higher power PSU's? If so, I'll be demanding one.
edit: nope, the 85W PSU is their most powerful. Either it's clearly not powerful enough, or we have bad PSU's. I think it's the former.

I know this thread is for the GPU, but this kind of a gaming question. I was wondering what your guys CPU gets up to after a gaming for a bit?
Mine was getting in the high 90's according to HWmonitor, but according to SpeedFan the cores weren't getting any higher than the low 80's. That was after just a quick 20 minute run through Mass Effect 1.
Is one of those more reliable than the other? And are those temps normal? My Sony Vaio FW only got in the high 70's running Mass Effect, of course it only had a T9600 C2D.

Although I agree apple should have used higher wattage psu's you should be thankful apple lets you use the battery to increase the power output.
Dell/HP and the like use a lovely tactic known as throttling instead. I would ratehr a bit of my battery is drained whilst I am needing the extra grunt than having my cpu or gpu clock down.
I have had a number of dells do this, Dell laptops throttle for both heat and high power usage, it used to drive me insane. Check out some of the dell sxps 16 forum threads for info.
Also its not all Apples fault, intel has allowed its cpu's to drive above tdp in all the i5 & i7 series cpus. The 45w tdp is often exceeded with max turbo boost. This caused a lot of problem when the first i7's came out as most manufacturers didnt realise this and a lot had thermal/throttling problems
Are you sure that the chips are exceeding the TDP? It would seem logical that turbo boost be limited by the TDP among other things. Do you have a source? I couldn't find any info other than it being governed by a "thermal and power limit" on Wikipedia.
It has been a general rule of thumb that the maximum power draw of components is around 30% higher than the TDP for ages. The aggressive turbo boost of the SB chips pushes this even further, as it allows the CPU to overclock even further when it's cold. No, I can't find any official docs, but I'm sure its true.
I will see if I can dig out some sources for you. But it was quite a while ago as this was big news when the first mobile i7's started hitting the shelves.
fair enough. it's not causing a problem. I'm just surprised that Apple wouldn't release a 90w charger...or something that would cover the power draw at maximum load.
but you're right, I'm really glad it doesn't throttle down. that's the worst.
Probably 640 x 480. Based on my experiences, there's no way he could be running it on the highest settings at native resolution and get such a wide ranging fps as 30-60. Maybe 20 fps, but definitely not around 45fps. Anyways, the poster apparently isn't using fraps or anything to actually measure fps.

Thanks both of you, that would explain why the 85W magsafe isn't enough.
