The new MBAís optional 1.8 Ghz i7 turbo boosts up to 2.9 Ghz on a single core and 2.6 Ghz when both cores are utilized.

First benchmarks are popping up and they areÖ impressive.


(picture by macrumors, reposted)

//edit: ok, those scores look just plain wrong. I assume they are using a test that factors in SSD performance and the 2010 17" MBP is running a 7200 rpm HDD.

Interesting...I guess there's really not that much of a difference between the i5 and i7 in the Mini. Both have VT extensions, both have hyperthreading. I run into processor issues often on my 2.26 C2D Macbook Pro, but I guess the difference between the i5 and i7 compared to what I have really isn't going to be that big of a deal.


I wonder how much of that is on disk speed, and what it'd look like if the MBP also had an SSD.

Yeah, I just realized that. For a second I thought itís a pure CPU benchmark but that wouldnít make any sense at all looking at the scores and CPUs.

Received my 13" i7 256GB MBA today, upgrading from the previous 13" C2D 2.13 256GB model.

Differences so far:
  • Display looks much better to me, the "banding" issue that looked like dithering seems completely gone. I assume the new MBA has new panels?
  • SSD is a lot faster in synthetic benchmarks. 246.0/263.4 MB/s average, 264.9/280.4 MB/s peak in the AJA system test at 4GB/1080p/10bit.
  • I never realized how much I missed the background lighting until now that I have it back.
  • The A,S,D,E and R keys have a certain feeling of stickiness to them that shouldnít be there and makes me miss these letters while typing. Not sure where this is from since the device is brand new.
  • The i7 or faster SSD isnít really noticeable in everyday use, except maybe 1080p youtube videos. 8GB RAM would have been nice to have.

MSI displayed their external thunderbolt graphics enclosure at CES using a MBP. Windows-only, although most consumers would want to use this under Bootcamp to play games anyway. Supports cards up to 150W according to the picture. Iíd love to buy this and a 6770 to play games like Skyrim on my i7 Air.

The Ivy Bridge processors aren't supposed to be that much more powerful than the Sandy Bridge series, right? I'm still debating selling my current 13" Air and upgrading to the new model, mostly for the BTO 8 gigs of RAM, but I can't decide if it's worth it or not.

Not really worth it. The spec bump is relatively small and you already have Thunderbolt, so USB3 is no big deal either.
In my opinion it canít be too long until the Air gets a retina display and a dedicated graphic chip.
13" @ 2560x1440 would be around 225 ppi, the new Pro has 220.

My late 2010 C2D MBA won't turn on anymore after it completely ran out of battery earlier today.

The light on the MagSafe connector is amber after 5h of charging, I've tried two different chargers without success.
I also tried resetting the SMC and PMC, no dice. The machine stays off when the power button is pressed.
Is there anything else I should try before opening the case in an attempt to temporarily disconnect the battery?

I ordered a CTO rMBP last week and figure it will be assembled within the next few days.
What worries me the most are the ghosting/image retention issues.
Someone on arstechnica mentioned that it only affected the very first batch of rMBPs and the QC issue is completely fixed now. It would be nice to hear from rMBP owners with this issue and how they solved it.

AFAIK Apple doesnít do direct replacements for CTO items and that worries me (even though my machine has not arrived yet).

Took it to the Apple Store and they wouldnít replace it.
I ordered an identical 2012 model (13"/4GB/256GB) over night because I didnít want to wait for a BTO model and this machine will be replaced by the Haswell rMBP anyway.

After pressing the Power-button it took me less than a second to figure out that thereís something wrong with the display. It looks pretty terrible with a strong blue-tint. Blacks arenít as deep and the color looks less vibrant.

As it turns out this one has a LG display whereas my two old models (2010/2011) have a Samsung. I calibrated the screen with Spyder 4 and the difference is much less noticeable now, but side to side, this calibrated 2012 screen still looks worse than my calibrated 2011.
Text looks sharp and black on the Samsung and somewhat grey/washed out on the LG, but Iím sure a person that has never used a Samsung-MBA before wouldnít notice.
Iím not sure if Amazon would replace it. Probably not. Sucks.

mbp - if the fourth one has the same issue then I'm giving up and getting an air.

Good luck, both LG and Samsung build screens for the MBA. Iíll leave it to you to guess which one has visibly better contrast and black levels.

Iíve returned my second 2012 13" now because both of my old (2011 and 2010) MBAs had Samsung screens and so the LG screens just look like s*** to me, even after calibrating with a Spyder.

From Anandtechís review:

quote:

I had some friends over and tossed them a pair of 13-inch MBAs. One had the LG panel and one had the Samsung panel. They used the MBAs and swapped after a short while. Almost instantaneously they could tell the difference between the panels. Everyone significantly favored the Samsung.

I was actually a bit surprised how quickly they noticed the difference. With these type of things I always assume I'm just more sensitive than most, but in this case the difference was noticeable enough to pick out. Everyone added (and I agreed) that the difference was most pronounced because they were able to switch between two. In a vacuum each one seemed fine.

On the topic of MBA temperatures, I have to say that my 2012 13" gets much hotter than my old 2011 13" when playing games on OS X.

The area around the WASD keys gets hot enough to be quite uncomfortable while playing Portal 2. The CPU temperature never goes beyond 85įC so I doubt itís a thermal paste problem.

Both machines are 100% silent and cool while idling/websurfing (without flash).

The 13" rMBP is basically an Air...with a retina screen.

In some ways it is (itís a lot smaller compared to the old MBP), in some ways it isnít (the weight difference is still there while traveling and itís not wedged to be almost flush with the desk like the MBA is).

To me the 13" rMBP would be a very†desirable machine if it had a GPU in the 650m range, but now that Intel is focused on closing the inegrated GPU performance gap with every iteration, I donít think we'll ever see dedicated GPUs in the 13" anytime soon.

Itís quite absurd that right now the MBA offers a noticeably more fluid and snappyô user experience than the flagship rMBP.

As for rMBA speculation, weíll probably see IGZO screens appear in products next year.
The improvements in power consumption pave the way for a rMBA. I would also expect the rMBA battery life improve to at least 8-9 hours then.

Although thinking about it, the iPad mini is probably going to be the first one to get the IGZO update.

Are these Haswell chips suppose to be super great? I want to replace my 2010 era 13" MBP with a new 13" MBA, but I don't need to and can wait another half year for the new ones. The way I see it, I think the current era MBA is already more powerful than my MBP, and my MBP is still doing great, but I like new and shiny things.

Current desktop leaks, rumors and speculations point at a 10% CPU (IPC) increase and a decent 20-50% GPU performance increase at the same TDP.
Clockspeed will apparently stay the same, give or take a 0.1 Ghz increase for marketing reasons.

I expected Haswell to bring much larger increases than that. The improved powerful iGPU is a very nice thing for gamers and the 13" rMBP, but it seems to take up a large part of the thermal envelope so that the CPU performance difference between Ivy Bridge and Haswell is shaping up to be moderate at best.

I've mostly been using Screen sharing from the iMac and my MBP to control it, however, occasionally the screensharing will get all kinds of visual artifacts, like black squares or corrupted video. I can usually drag a Finder window around and get it to "Repaint" those areas, but this is pretty annoying. If I connect an actual monitor then the video looks fine on the real monitor, it's just messed up over screensharing.

Anyone else experienced this? Is this a hardware problem or a bug?

I am experiencing the same issue on my headless Mac Mini (2010 or 2011).
I havenít found a way to get around this, although I often use Splashtop on my iPad which is much more responsive than the OS X VNC client.

My battery is now below 50% capacity an it is time to replace it.
The new 2013 MBA has a battery with a "carrier" and connector that appears to be identical to the old one.
It has a nominal voltage of 7.6 V instead of 7.3 V, but a ~4% increase doesnít seem like a huge difference considering the voltage of Li-ion batteries fluctuates depending on their state of charge. The capacity would be higher too (7150 vs 6700 mAh) which would be nice for that extra half an hour of battery life or so.

FWIW, I replaced the battery of my 2012 13" MBA with the newer, larger 2013 battery (A1496 instead of A1405) it is a success so far, 5 cycles in.

It should give me slightly longer runtime at no additional cost. My old battery pretty much "died" around 515 cycles, it had 38% maximum capacity left at that point. The nominal voltage of the new battery is 0.3V higher than the old one, but since the battery voltage rises and falls depending on the level of charge, I donít think this will be an issue.

I do wonder what happened to the "80% at 1000 cycles" claim mentioned here.

quote:

Your new Apple notebook features advanced battery chemistry that greatly extends the batteryís lifespan. The built-in battery of your MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles before it reaches 80 percent of its original capacity. In addition, Adaptive Charging reduces the wear and tear on the battery giving it a lifespan of up to 5 years.

I wonder if the firmware of your 2012 has the battery capacity hardcoded at all.

In theory its possible that the final cutoff voltage for the new 2013 battery is also 0.3V higher and thus a complete discharge could be worse for this battery than the old one, but I try to avoid running the machine down to below 5%.

System Report does show the correct maximum capacity. I did a full SMC and NVRAM reset right after replacing the battery, then charged it to full and let it run down to zero for calibration purposes.
Not sure if that was a smart idea as that single deep discharge seems to have cost me ~200 mAh of the maximum capacity but whatever.

I imagine a USB 3.0 or Thunderbolt enclosure with a desktop SSD in it would feel as fast as the built in SSD for most everyday tasks.
