13-inch Gaming Performance under Windows
Like I said earlier, this is the first Apple portable with Intel graphics in over two years. What does this mean for graphics performance?
Bad things. See, when Jarred looked at HD 3000 in our SNB mobile testbed, he found that it was a bit faster than the 320M at low settings, and a little bit slower at medium settings. The i5-2415M has the same specs as our testbed, with 12 execution units with a max clock speed of 1300MHz. Given the gaming performance from our Sandy Bridge review, I was actually pretty optimistic that the new 13" MacBook Pro's graphics weren't actually worse than the outgoing models.
Oh how I wish I wasn't wrong. 3DMark scores go down about 20% relative to the SNB testbed and stay within 10% of the old MBP. So far, so mediocre.
The good news in the gaming numbers is that everything is playable, at low settings at least. Unfortunately, performance is, for the most part, a lot slower than the outgoing 13" MBP. 30% slower in STALKER, 20% slower in Mass Effect 2, DiRT 2, and Battlefield: Bad Company 2, 10% slower in L4D2, and a hair faster in StarCraft 2. StarCraft isn't actually that surprising, since it's by far the most CPU-centric game in our benchmark suite.

iPad is only just starting to sell and iPhone still has lots of space to grow. The trend is Apple are making more units and more money from ARM specific products.Nvidia has just recently stated that Project Denver will be ARM 64 bit. And aiming at HPC and Desktop. Full Compatible with current ARM instruction set.
Currently Apple must have a ARM version of Lion testing, and few years down the road, they could switch their Mac over to ARM 64 bit. Using a single Instructions Set for their whole product line.
For some reason i have been thinking that Apple and Intel aren't doing too well together like anand has felt. I dont think Thunderbolt is any indication of their current relationship. it is merely they have been working on it for such a long time, no one wants to lose our at the end.
Of coz it could have been the other way round x86 moving into iPhone, although that depends how much intel is willing to bend towards apple.

Anand,Can you guys run your high-end 15 through the Windoze tests that were used on the 13?
Thanks

Hello guys!First, I have to say this review is really awesome, as usual! Just what I was hoping for. The thoroughness and practical sense of your reviews continues to amaze me every single time.
For the 13" MBP, you mention "bouts of instability". Can you elaborate on that? Stuttering? Crashes? In what way do you notice that instability? I'm a little concerned now.

my wife has been bugging me about our wifi since we moved and get a poor signal in a lot of the new apartment. told her i can get a new router with 3 antennas but we will also need a new laptop as well with the antennas to take advantage of it.which brings me to my question. i know the 15" model has the 3 antennas. does the 13" do MIMO as well?

They all use the new card.By the way, have you tried switching wifi channels, or installing DD-WRT and boosting signal? Even so, you don't need a new laptop after getting a new router if signal strength was the only problem.

i'll try that, thxa lot of wifi around me these days. we only have work laptops now so that would be our only personal computer if we bought one. i was looking for the cheap SB models when they come out

"told her i can get a new router with 3 antennas but we will also need a new laptop as well with the antennas to take advantage of it."This is not completely true. A base station with multiple antennas CAN do the equivalent of phase-array beam steering to direct most of the output power towards the target laptop. The laptop will thus see a stronger signal, and one of the better modulation schemes (eg 64-QAM 5/6) can be used rather than one of the weaker schemes. Thus your laptop, even if it has only one (or two) antennas can still see better performance.
Note, this is a theoretical possibility. I do not know the current state of the art in how well base stations utilize the various forms of transmit diversity that are available. And no review ever seems to talk about this stuff, either by testing how well the kit works with a single antenna device, or by talking to the manufacturer about what's in their product.

The 13" does have 3x3 MIMO as well, the exact same broadcom solution as the 15" I tested extensively.-Brian

Anand and crew,I am very disappointed with the battery life numbers in this review. This is the first review of a laptop where it appears you have used a 3rd party app (Cody Krieger's gfxCardStatus tool) to significantly inflate the numbers of the new 2011 systems. 35-60% by your own numbers back on the discrete GPU battery life page, which you then fail to report in the battery life tables later on!
When you are tasked to review a system (especially an Apple product I might add) it should be reviewed as is, with no tweaking or 3rd party add-ons to boost performance/benchmarks. When have you EVER installed an add-on for a Windows-based laptop to improve performance/life? I can't think of one.
At best this was a simple oversight where you have benchmark numbers WITHOUT the gfxcardstatus, at worst this was a cover-up job which I have always argued in the forums against and on your site's behalf.
Please update the tables to show what a stock newly-purchased laptop at the Mac Store would deliver.
I am very disappointed in this coverage.
