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.

So I roll with my optical drive replaced with a Vertex 2 SSD inside an OptiBay daily. It's an awesome combination if you can do it.One problem I noticed however is that Apple's EFI won't boot optical drives other than their own $79 external drive. That means if you want to use boot camp, you have to install Windows with the optical drive (internal SATA) connected, then do the swap to OptiBay SSD + HDD.

I'm just not that interested in this years lineup. The better CPU performance is nice but given how much more features Windows notebooks provide today, I feel I can rely on Windows notebooks as a desktop replacement much more than I can a Macbook Pro. I will still use my MBP 13 2010 for home use but for business, I rely on my Windows laptop.Braddik - Thursday, March 10, 2011 - link
Amazing article! I love how thorough and detailed you are. Mad props! I work in a medium-large size organization and the Dell vs. Apple debate is hot right now. Our Mac user base is growing, but the majority of the organization is Dell. I would love an article that compares the performance/value/support of MacBook Pros vs. Dell Latitudes in the Enterprise environment. Which is better? Can/should organizations feasible make the move to a full Mac environment? I would love your input! Thanks!Anand Lal Shimpi - Friday, March 11, 2011 - link
Thanks for the kind words. I'm not sure I can offer much advice in terms of how the MBPs fare in an enterprise environment. While I know of many corporations that now issue OS X systems as an option, those systems typically have some form of Windows on them (either via Boot Camp or as a VM).Perhaps someone else may be able to offer more input?
Take care,
Anand

I still think it's too early to completely throw away desktops.With my T410, I also made the change to use it as my main "working" computer. At home, I can dock it and use my big, comfortable screen. It's very fast in "normal" usage like simple programming, texting, surfing, some "medium" load graphical stuff, some MATLAB etc. etc. - it's just perfect.
But as soon as I want to do really heavy stuff like hours of video encoding, I still switch to my desktop with 4 or more cores and a fast dedicated GPU. It's just not the same and I really don't like to stress my laptop that much (allthough it is a Thinkpad). I don't know - I'm even less comfortable with a quad in my notebook. I don't know, but it's just not the same as a Desktop for really heavy stuff.
I do like the new MacBooks - I don't like the resolution of the 13" model though...it's awful...

While i expect a Mac Pro refresh late 2011 early 2012 I wonder if it could be the last. With the discontinuation of xserve and as this review demonstrates a mobile CPU matching less than year old server level parts in performance and thunderbolt allowing highspeed access to a NAS box I can see Apple discontinuing there last product targeting solely the professional market and truly becoming a CE company.rural_oregon - Friday, March 11, 2011 - link
Yes, I have to agree with you. With macs only 20% of Apple's total revenue, and the mac pro only perhaps 5% of the mac revenue, at some point soon it just won't be worth the effort. I think it's even possible that there may not even be a sandy bridge mac pro.tipoo - Friday, March 11, 2011 - link
It certainly seems like a possibility. Apples focus really has shifted to mobile devices, and its Mac revenues are only about a fifth of what the company makes. I can't imagine the Pro is any substantial percentage of their revenue, 1-5% perhaps. Might not be worth the effort for them. On the other hand, it would irk mac developers and creative pro's.wast3gat3 - Thursday, March 10, 2011 - link
Just a short thanks for such an in-depth review.I have a mid-2010 15" MBP and am upgrading this week to the 2011 15" MBP as the performance gain is just too good to pass up. Interesting though that Apple locks the TRIM support in to their own SSD. I'm still going with the 7200rpm 500GB option and will move that disk to an opti-bay and the 3GB controller now knowing that they are using B3 stepping and fit a 6gb sata SSD. Hopefully LION will fix that TRIM support or some clever cookie works out how to enable it.
Once again thanks!

I always wait for AnandTech reviews because they are almost aways the most comprehensive. I love how the technology behind the reviewed product is summarized, and that there is some footwork to better describe the exact hardware being used (e.g., CPUs for MacBook Pros).Thanks for the informative reviews. No one comes close.
