Application Performance in Windows
by Vivek Gowri
In keeping with recent tradition, I'm in charge of evaluating the new MBP under our Windows notebook benchmark suite. Mostly, the MBP works very well as a PC, something I looked at last year with the old 13-inch MacBook Pro. I have the new base 13 in the labs, and I must say, the overall experience is pretty similar...unless you're gaming. But I'll get to that in a minute.
Unlike on the Air I was testing last time around, the Windows install went pretty smoothly thanks to the built-in optical drive. Unfortunately, that's probably going to be the last time I ever use it. And also unlike the Air, there's no problems with storage space here—with the 320GB drive included in the base 13, you have more than enough space for two moderately-sized OS install partitions.
With Windows and Boot Camp drivers out of the way, I fired up our notebook benchmark suite. The new MBP is the first dual core Sandy Bridge notebook we've had in our labs, so I was pretty interested in seeing the performance relative to Arrandale, as well as the old Core 2 Duo-based MBP13. According to CPU-Z, the base spec 13 that I have has the i5-2415M inside, a dual core processor with HyperThreading and clocked at 2.3GHz with max turbo frequency of 2.9GHz. The 2415M is an interesting chip, closely related to the i5-2410M. It's so interesting that Intel doesn't even have a product page for it, which made me curious as to what the difference between the two is. Turns out, the 2415M is the same chip as the 2410M, just in a smaller package. The normal mobile Core i5/i7 processors have a 37.5 x 37.5mm PPGA (plastic pin grid array) package, meant for Socket G2 (also known as rPGA 988B).
The 2415M, on the other hand, has a package size of 31 x 24mm with a micro-FCBGA mounting method. It's the same package size and mounting as the low voltage and ultra-low voltage Sandy Bridge processors, using the same BGA 1023 socket. Apple probably chose the 2415M to make packaging around the processor easier. Smaller is always better in the Apple world.
The other interesting wrinkle here is that Apple has forgone a separate graphics chip for the first time in a very long while. This is the first Apple with Intel graphics since the MacBook's January 2009 refresh brought Nvidia 9400M graphics, and the first MacBook Pro with Intel graphics. Ever.
What does all of this mean for performance? Let's take a look. If you're comparing to the old Core 2 Duo based MBP13, CPU-based performance is almost two times faster across the board. Given the huge jump in power between Core 2 and the further two generations of Core processors, this makes a lot of sense. It was seriously about time that Apple moved on from Core 2 in its smaller notebooks, and this huge performance jump is a direct result. We'll see what happens with the regular MacBook and MacBook Air, but I'd expect a similarly large increase in performance in those models when they're next updated as well.
Looking at the Arrandale-based Core i5-430M, which at 2.26GHz is a logical point of comparison to the i5-2415, we see that performance has improved 15-20%.
This doesn't look as impressive as the gains in performance we saw with our first look at the mobile SNB quad-cores, but Sandy Bridge quads are clocked a lot higher than the preceding Clarksfield chips. Our quad-core SNB mobile testbed had an i7-2820QM, with a 2.3GHz core clock and max turbo frequency of 3.4GHz. The 2820QM replaces the 1.86GHz i7-840QM, so the clock speed is 24% higher. Factor that in, and the increase is more in line with what we saw from the dual-cores.
The big deal here is that now, the lowest end SNB i5 performs roughly on par with the top end Arrandale i7 dual cores. Like Anand said in his Sandy Bridge review, you get yesterday's top of the line performance for a much lower price.

I'm really considering splashing out on the 13" but I've read countless articles and all I hear is the glossy screen is either horrible or awful. I don’t want the 15", I need the portability and I don’t know what on earth to do!??????????Then comes the SSD issue, if I want this option I have to wait 6 weeks!
I can always get this later down the line I guess?? Well from what the article suggests??
Any help (opinions) would be great as right now I’m lost! :(

If a person bought a MacBook Pro in the last 18-24 months,I don't see the reason to upgrade unless you're on the Bleeding-edge of performance needs and Mac your living with your Mac. Many Apps and advanced Software aren't even optimized to take advantage of multiple Cores,or Hyper-Threading/Turbo Boost. I don't care as much for Auto Switching Graphics,since I have total control of my Graphics with my March 2010 MacBook Pro 17"/Core 2 Duo/2.8 Ghz/4GB RAM/AG/500GB HD/512MB or 256(IG) VRAM-dual cards/express card. if I was buying new today,Hyper-Threading and Turbo Boost schemes would be OK,but there's no way that I'd trade or sell my machine for these updates! To me,speed hasn't been an issue in 2 or 3 years! My 2006 20" iMac was at 2.0 Ghz,and the newest Macs are 2.0-3.0Ghz or so. I know that Sandy Bridge is faster than a Merom Core Duo,but most improvements seem to have come from adding more Cores and RAM,so that more tasks can be done simultaneously! I don't care for gimmicks,Turbo-Boosting,Hyper-Threading,and poorer graphics to convince me to upgrade my Macs. Unless you are a Digital Video Content Creator,or other high-powered user,or your Mac is 3 yrs. Old or so,you should Max-out your RAM,get a faster HDD or an SSD,rather than buying a Whole New Mac! If you have the money to spend,good for you,but a combination of Power,Battery-Life,and Portability,are the REAL issues! I wish people would stop telling others that they're Idiots for paying Mac prices,since it's our Money,and only YOU can determine what's good value for the Performance,elegance,and Stability of Apple Hardware!rredge - Thursday, March 17, 2011 - link
Today, the local Apple store acknowledged that my 15" MacBook Pro is not functioning properly and refunded the purchase price despite the fact that I was just past the 14 day return period.The problem is that the computer ceased to respond to the trackpad even when rebooted with the power button.
In the course of trying to figure out what the problem was, I discovered that there are reports of people experiencing similar problems for all three models (13", 15", 17") on Apple's support forum, where one thread alone now runs 19 pages, as well as elsewhere on the internet.
The Apple store personnel told me that Apple has not acknowledged that there is a problem with this line of computers, although they acknowledged in less than two minutes that my computer has a problem sufficiently serious to warrant a refund out of the return period. I declined a replacement because they expressed ignorance of the issue, indeed said that Apple did not acknowledge an issue, and were unable to give me any assurance that a replacement would perform any better.
The questions at this point are how widespread this freezing problem is and whether Apple is going to acknowledge it and fix it.

The second paragraph should have said that the computer ceased to respond to both the trackpad and keyboard.nitrousninja - Thursday, March 17, 2011 - link
I saw the benches but I dont know if that translates into a big real world difference in SSDs. I'm mostly doing stuff in Word/Excel, some light video editing/converting, and occasionally some WoW. This would be in the base model 13"Should i go with the stock 3GB 128GB SSD or the OCZ 6GB I can get at Microcenter and install it mysel?. I've never done that on a Mac.
Thanks for the help!

Doubt you're still wondering but, if you want to have any space left after installing an OS and still want an SSD then you should splash for the 128GB SSD or wait till a reliable larger SSD is available. I wouldn't go less than 120GB.As to whether you should get an SSD, just ask yourself this question:
Have you ever sat, even for a moment, and wondered why an otherwise well specced (but magnetically driven) computer seemed slow?
If yes, then you'll likely be able to set that question aside by putting in an SSD.

Hello Rredge,how frustrating your experience sounds!
2011 was the year I was finally supposed to buy myself my 1st ever MBP after 18 years in the Windows environment.
It took me long enough to choose between a 13-inch or 15-inch one but then I started reading about these freeze issues a lot of users have been facing. being French i only heard about this problem within French forums and i was hoping this would have to be a specific problem for a batch of units delivered in France but now I have to admit this really is a larger scope problem.
For what it's worth there were comments on the forums I went through about I-Stats being a cause for these problems as it installs by default with a settings that take over the fans control.
Did you have that app on your computer?
Best regards
Tranksen

Bonjour Tranksen,The fan on my computer was acting normally when this happened and I do not have that widget installed. I was running Terminal, TextEdit and Safari and the processor was under extremely light load.
You will find a good deal of discussion about this problem on the Apple U.S. support forum at http://discussions.apple.com/category.jspa?categor...
This is not an imaginary issue. Apple agreed to the return of my computer for full refund despite it being outside the 14 return period.
I would consider repurchasing one of these computers, but not until Apple clarifies what the problem is and fixes it.

You said that noise was an issue with the larger MPB, but I'd like that to be quantified in decibels and compared to other laptops in a table, in future reviews.Omid.M - Monday, March 21, 2011 - link
Can the AT team comment on this please:http://apple.slashdot.org/submission/1504006/2011-...

Can you guys duplicate this issue? Is it just simple overheating and poor design on Apple's part? I really want to know...
Also tweeted to the three of you. Thanks for your thoroughness, gang.
