    So I have done some research. The SSD is WAY nicer and more GB which might increase performance ALOT.
    I forgot, whats the diff in speed in SSD and HDD? I saw a huge diff I was just not sure.
    Also,
    http://www.macrumors.com/2008/10/18...oding-of-h-264-on-new-macbooks-pros-and-airs/
    Seems that the new graphics card is WAY better for modern tech.

    But seriously, anyone with a Rev. B. What are your impressions?
    I did not see a thread of people talking about the new version so I didn't know. Let me know guys :)

    More GB in a drive =/= better performance, if the new SSD's are better its simply because the technology has grown up a little.

    What I meant was Not enough free drive space will hamper performance, a larger drive will not necessarily improve performance but it can help.


    With basic tasks though, I see no need for more then 2GB of ram. But 4 would be nice for other functions.

    you don't see a lot of people talking about the new revisions yet because they haven't arrived. many have gotten shipping notices but no one's received yet. you will see many more reviews in the next week.

    Oh, really? See I thought it had been long enough by now, like almost a month. I guess I missed something. Thanks. I shall wait.

    Yeah, the MB and MBP were available pretty much right after the conference, but the MBAs needed longer to start shipping. Nobody knows why.

    I'm looking forward to hearing the reports this week though.

    Nice, thanks for the help guys! I am excited. I am buying one for college, I just don't know if I should wait for an update. Does anyone have a guess when the next revision/update will be. I still have a year before college.

    with the new revision the MBA should now be equivalent to the the MB now and not slower.

    What MacBook might that be? Because surely not the 2.4GHz Aluminum one....and its still a bit behind the 2.0Ghz too (4200rpm is gonna kill you)

    At this point, I think it's a pretty good guess that the delay has something to do with the new 4200rpm 120GB hard drive. Thus far no one with that configuration has said they have shipping confirmation (only SSD versions to my knowledge). Plus it is the one major piece of hardware that is significantly different, and not shared among the MB or MBP.

    Either way, back to the original question, is the new revision "WAY" better? Obviously depends on your definition of "WAY" :) For a big gamer fan like myself, the major improvement in the graphics is enough to warrant an upgrade. Usually when gamers are upgrading they often look for graphics/performance improvements in the 50% and above range - in this case we are talking close to 500%!! This change should make the MBA a legitimate portable gaming computer on top of all the other great stuff it's already capable of.

    Now add to that additional hard drive capacity and more efficient processor/mainboard/memory, and I'd say that yes - it is way way better!!

    To an extent.....2.0 still has roughly a 10% increase in speed, the SSD still has slower write times than a 5400rpm HD, and the 9400M is still clocked lower (4x) thann the MacBooks (5x)

    but yeah its not TOO far behind the 2.0 MacBook.......with that being said its still $1,200 more than the 2.0 MacBook (With SSD as you said) =\ Im so torn....I want a 3lb laptop that runs OSX why must it be so much!!!!

    I agree that the definition of "way" better is relative. Since I don't game or run extensive rendering on my MBA, even though the graphics may be 5x what it was before - it makes little difference to me.

    I'll also add that the 9400m upgrade is still just a midrange card. A benchmark of the 9400m in the Aluminum MB 3dMark06 score was ~2300. You can bet that score will be less in the MBA. For comparison, my single desktop 8800gt 512mb card on my quad core desktop scores over 14k on 3dmark06.

    I'll wait on reviews and benchmarks before I decide if it is "way" better.

    Somebody correct me if I am wrong here, but I am fairly certain that at the current time, the Mac OS does not support GPU decoding for h.264 videos - all of them are still processed by the CPU.

    There is no support for GPU decoding for compressed .x264 files in VLC anyway.

    Youtube videos are dependant on CPU, not GPU - and well... your internet connection.

    So.. to answer your question - not yet and no.

    Even with GPU support, the only files you would see a noticeable difference are HD h.264 files - and at way over 10gb per movie in 1080p, there is little reason why you would need it anyway.

    The current MBA line has no problem playing 720p/1080p x264 files with the CPU independently anyway.

    Actually in traditional drives, yes it does. Say, for example's sake you have 2 2.5" hard drives. Both 2 platter, 5400RPM, and from the same model range by the same manufacturer. Only difference between the drives is that one is 100Gb and the other is 200Gb. Because the higher volume drive has double the density of information store on it, it can read more information than the smaller drive in exactly the same time. You won't get double the performance, but it is a boost none the less.

    Now, I known this has nothing to do with the SSD side of the equation, but it does mean that your read speeds from the 120Gb traditional drive should be slightly better :)

    Well it's not really a midrange card since it's still integrated.

    Agreed on this point, until we get real gaming data it will be tough to tell. I'm expecting something like 2000 for the 3DMark06. However, a more important data point for myself was seeing the video of the guy running Warhammer Online on a new Macbook, that is really the standard I've set for my personal gaming. I'm not going to compare performance to my desktop, which like yours is running a much more substantial video card. To have a complex game like WAR running on a netbook-weight-like portable computer... I just wouldn't have thought it possible a year or 2 ago.

    I do like to think of it like this: if there was a game I was barely able to get running on the original MBA's X3100, at say, 5-10fps (like Warhammer for instance) - I now expect it to be 100% fully playable at 20-40fps. Or a game that I could run in the worst settings before, would likely run in highest settings or a higher resolution. To me that's a very substantial improvement.

    Yeah, the SSD is deff AWESOME and very fast. I am sure you CAN compare a 128 GB SSD MBA to a 160 GB HDD MB

    But remember that the MB and the MBP are BOTH capable of the SSD upgrade... so it depends.
    If I get an air I WILL get the SSD upgrade... its totally worth it!

    obviously excluding gamming :p

    Oh and the graphics card, BOOOOOOSTS performance ALOT.
    The 9400 has some extra in it that works really well video.... here is proof:

    In addition to the graphics boost, the new 45nm processor has a bit more L2 cache and runs cooler; 17 watts vs. 20 watts for the old rev-A 65nm processor. This should make it a touch faster and cooler on your lap. For the first time, I'm considering an Air. Since the new MacBook doesn't come with Firewire either, in my mind it's now much less attractive than the Air.

    Perhaps that's part of Apple's intention by dumping Firewire on the MacBook. Those like me who might not have considered an Air because of the lack of Firewire, now consider it because the low end doesn't have it either. (I don't want a MBP because it's larger, heavier and costlier; even though I would really like Firewire on my new portable.)

    Please don't take offense to this, but it is hard to read your post and believe you share an objective viewpoint.

    While SSD has faster read times, the write times have been reported to be slower. From the the Ars review of the SSD vs HDD:

    Does Ars think SSD is worth the premium?

    Even with the faster read times, raw computing power of a 2.0ghz or 2.4ghz macbook will still trump the macbook air.

    Regarding your "proof" that the 9400m "works really well":
    Your proof has never been substantiated and is just a rumor. In fact, a follow up from arstechnica says:

    Before you get everybody's hopes up, I think everybody should wait until benchmarks and reviews are released to objectively judge the differences.

    Yeah your right... and NO I did not take offense. You gave alot of good points. Just a thought I was conveying. I was talking about read times, not write times. But you all have to agree that SSD is better.
    Still, for basic use, I think the Air can almost compare.

    I'm not sure I'd agree that SSD is better. Perhaps you mean compared to the tiny hard drive in the Air.

    I don't pretend to be an expert but what I've been reading would lead me to believe the long-term dependability of SSDs is in question. Will they wear out before a hard drive will? I don't know, but I'm more inclined to go with a hard drive any day, than an expensive unproven SSD, which is only marginally faster.

    Its new tech, so it hasn't been proven bad yet. The only problem that COULD happen is the reader dies out. You could write and delete info in the same place a million times without problems, but how long will the reader last?

    Yeah, What I am saying is, SSD is going to be our future. Just needs to come down in price :p
