Performance
For our performance comparison I actually dusted off some of our 2008 8-core Mac Pro data just to show you exactly how close to a high end desktop the new quad-core MacBook Pro has come. Note that we only have comparative data for a few benchmarks so you may see the Mac Pro disappear from a few charts.
Keep in mind that the Mac Pro numbers are taken with a 3.5" hard drive (vs. the 2.5" HDD in the MBP). The big difference however is microprocessor architecture. In 2008 the Mac Pro was still running Core 2 based CPUs, while Sandy Bridge is two tocks away. What the new MBPs lack in TDP headroom and core count, they can make up for in clock speed. The result is that for the first time since I've been reviewing Apple hardware we have portable Macs that can truly hang with their desktop brethren (with some caveats of course). In order to truly bridge the mobile/desktop gap you definitely need an SSD; a 2.5" hard drive just isn't going to cut it. The Mac Pro still has a pure core count advantage. The reason I feel like the mobile/desktop gap has narrowed is because while I feel that there is a general performance benefit when going from 2 to 4 cores, it's far more difficult to find applications or usage models that take advantage of 8 or more cores.
The gap will grow once more as the iMac and Mac Pro get updated with Sandy Bridge hardware later this year, but I suspect that for even desktop users a 15-inch MacBook Pro paired with an external display may be near perfect. I believe this is a big reason for pushing Thunderbolt in this generation. While the standard may not really take off until next year, the new 15-inch MBP is definitely built for desktop replacement usage models and for that to work without sacrifice you need high speed external storage.
Adobe Photoshop CS4 Performance
The Retouch Artists Speed Test we use for our CPU testing under Windows also works under OS X. We're running the exact same benchmark here, basically performing a bunch of image manipulations and filters and timing the entire process.
Photoshop performance is just amazing on the new systems. The high end 15-inch MacBook Pro is actually faster than last year's 8-core Mac Pro. Of course this is because Photoshop doesn't scale perfectly with core count but it just shows you just how powerful these new quad-core CPUs are.
Owners of last year's 13-inch MBP will notice that the new high end 13-inch can run through our CS4 test in roughly half the time. The performance improvement is of course exaggerated because Apple kept the 13 on Core 2 for longer than it should have, but what's important is that the new 13 is really fast.
If you do a lot of Photoshop work, the Sandy Bridge upgrade will be worth it.
Aperture 2 RAW Import
For my Aperture test I simply timed how long it took to import 203 12MP RAW images into the library.
Aperture performance is similarly class leading. Here the 2010 Mac Pro actually outperforms the high end 15 by around 6% but the fact that we can even mention the two in the same sentence is huge.
The new 13 is still really quick, itself faster than a Mac Pro from as recently as 2008 in this test.
Cinebench R10 & 11.5
I’m a fan of the Cinebench tests because they lets me show off both single and multithreaded performance in the same workload. First, the single threaded performance:
Single threaded performance is really where these systems shine and it's what makes them feel so fast in normal usage. Even the base 15-inch MacBook Pro has better single threaded performance than last year's high end model.
You'll notice that the 13-inch 2.7GHz MBP has a bit of an edge compared to the 15-inch 2.3GHz system here. Although both chips can technically turbo up to 3.4GHz with only one core active, Apple seems to limit the 13-inch dual-core less. As a result it will sometimes have higher single threaded performance than the 15. I noticed this in actual usage as well. The advantage is very subtle and really only visible if you do a side to side comparison however.
Multithreaded performance is obviously a huge boon on the 15-inch MacBook Pro. With four cores and eight threads the new 15-inch MBP behaves a lot more like a desktop than a notebook. Multithreaded performance is also one area where the high end Mac Pros do a lot better as they have twice the cores of even the 15-inch MBP.
Quicktime H.264 Video Encoding
Our final benchmark is more consumer focused. Here I'm taking an XviD and converting it to an iPhone-supported H.264 format.
Despite missing Quick Sync support, the 2011 MacBook Pros do very well in our video transcoding tests. If Apple does get around to enabling Quick Sync you can expect the performance advantage to grow even more.

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.
