At medium settings, it's a bit worse, but L4D2, Mass Effect, STALKER, and SC2 remain almost playable. Battlefield and DiRT, not so much. Overall, we see performance goes down from the 320M by just under 20% on average (not counting StarCraft, which is again marginally faster due to the reliance on CPU performance).
We see a similar result in the Cinebench 11.5 OpenGL test—a 24% decrease in performance relative to the old MBP.
Given the huge leap in CPU performance, I'd have been okay if the graphics stayed on par with the previous MBP 13, but I was a little disappointed to see it that much slower. This is a weird one, since the same GPU gave us significantly better performance in the SNB test system. The only explanation we have has to do with turbo. The max turbo supported by the HD 3000 in the Core i5 2415M is 1.2GHz, down from 1.3GHz in the 2820QM. Now max clock speed isn't enough to explain this performance difference, but perhaps under Windows the 2415M's GPU doesn't turbo up quite as aggressively as the 2820QM's.
Anand consistently saw 10-15% faster results during the first run of a benchmark than the next four or five runs of the same test. This is probably due to thermal limitations—heat soak and overheating are pretty time-honored MBP traditions. However, my system shouldn't have been affected by thermal stress over time—I let it sit for some time between each benchmark run to let it cool, just to eliminate residual heat as a factor.
Based on CPU-Z, Apple isn't underclocking the GPU—it's running at the same 1.2GHz that's on the Intel spec sheets. The difference in performance is a little odd. The MacBook Pro, especially in 13-inch form, does have the potential to be thermally limited due to the size of the enclosure, but I'm not sure why a supposedly low-power graphics solution would be so thermally limited, even when testing to avoid the effects of heat build up as much as possible.

Total NYC sales tax is 8.875%.NY state tax is only 4.5%

i'm sorry... state is 4%, city is 4.5%, plus Metropolitan Commuter Transportation District surcharge of 0.375%= 8.875% sorry... mixed up the city and state rates.gstrickler - Thursday, March 10, 2011 - link
What are you talking about? Most of us non-gamers don't even need a dedicated GPU, much less 256MB of graphics memory. I'm currently running on a late 2007, 15" MBP which has an 8600M GPU with 128MB of graphics RAM, and I only use it because there is no IGP on this machine. Once you get to the level of the Nvidia 9400M, IGP is plenty for a non-gamer, and even 32MB allocated to graphics RAM is more than adequate. The exception is if you need OpenCL support, since Intel's IGPs don't support OpenCL.I wish Apple offered a 13" MPB with a higher resolution (1440x900) matte display or a 15" with AES-NI and without a dGPU. I could use the faster CPU and HT, but I don't really need quad-core (but it's nice to have it available when on AC power), and battery life is far more important to me than a GPU or maximum CPU speed.
In fact, what I would really like is a 15" with matte display, no dGPU, Core i7-2720QM (for AES-NI support) with the ability to disable 2 cores/4 threads when on battery power. The 2011 15" lets me get close, if I use gfxcardstatus to disable the dGPU. If I can get software to disable 2 cores when on battery, it'll give me everything I'm asking for, but at a fairly hefty premium ($+150 for the matte display, $+400 for the Core i7-2720QM and Radeon 6750M + 1GB that I'll never use). Of course, what that means is that I'll either get the entry level 15" without AES-NI support and use gfcardstatus to disable the dGPU, or I'll wait for the next update and see if the options are any better.
Notes to Apple:
1. Make a matte screen an option on all machines, for no more than a $50 premium (no forced upgrade to a higher resolution)
2. Offer a 15" without a dGPU (e.g. make the dGPU a separate plug-in module)
3. Offer a 1440x900 screen for the 13" MPB.
I doubt I'll see any of those, but it doesn't hurt to ask.

"Most of us non-gamers don't even need a dedicated GPU"Most people don't need a truck, that doesn't mean no one does. This is branded as a pro machine, and at nearly 2 grand the GPU doesn't fit the bill.

MAcbooks are thin, long battery life, nice screen and good build quality first. specs second. until sandy bridge came out laptops with long battery life cost just as much as a macbook or more.a lot of the people that buy these are mobile pro's who need to use a laptop for hours while away from a power source

256MB is fine for the 64xxM series GPUs. The performance improvement going to GDDR5 and a faster GPU is much higher than the improvement from 256 to 512 would have given. For customers who really need the additional graphics performance (and corresponding graphics memory) apple is offering the very fast 6750M with 1GB.Demon-Xanth - Thursday, March 10, 2011 - link
...Apple is more like Sony than Acer? Their core buisness is no longer computers, but gadgets.michael2k - Friday, March 11, 2011 - link
Um, this was evident in 2001 when the Titanium PowerBook was first unveiled, then the iPod later that year, then the music store in 2004, etc.Also, you have it backwards, their core business is computers, they just happen to know how to turn computers into gadgets. They treat the iPod like a computer (firmware updates on a regular basis), which means they aren't disposable. Contrast that to the average phone OEM with Android who won't see updates for longer than 6 months, where Apple pushes updates to their iPhone for over 29 months.

Nearly all of Apple's products are computers:Mac Pro = desktop expandable computer running OS X
iMac = all-in-one desktop computer running OS X
Mac Mini = non-expandable desktop computer running OS X
MacBook Pro = high end laptop computer running OS X
MacBook Air = high end netbook computer running OS X
MacBook = basic laptop computer running OS X
iPad = tablet computer running OS X
iPhone = handheld tablet computer with phone running OS X
iPod Touch = handheld tablet computer running OS X
AppleTV = multimedia appliance computer running OS X
OS X has two variations - Mac OS X and iOS. The core operating system is the same for both.
Apps for both are written using Apple's XCode Development System.

I'm surprised SSD isn't standard to begin with. $1199 for a 13" laptop and you don't even get dedicated graphics? Seriously? The HDDs aren't even 7200rpm. This is insulting to the nth degree.If you want a solidly built, well-spec'd, thin and fairly priced system, get the Envy 14. You get 7200rpm HDD, dedicated graphics, an HD webcam with TWO microphones (necessary for sound cancelling), a backlit keyboard and even Photoshop and Premiere.
Until Apple drops their prices to a realistic and reasonable level, avoid it completely.
