45 NM means > 8% increases in the MBA! Reliable, Cool, Quiet, Dependable, Working Mac
^ ^ ^ Reply to the post by SeanU above. ^ ^ ^
I never said that it was the CPU only providing the performance differences between rev A and rev B MBAs. The other poster's point was since the rev A and rev B MBA have the same clock speed they are the same and could not be "Worlds Apart." I replied separately to that in another post.
The problem is your reply above is extremely misleading as it does not report all of the information.
It should be clearly noted that the Merom chip was/is part of the overheating problem with the original MBA. So, I think you failed to miss the point that the 45 NM Penryn SSF 17W CPU is FAR SUPERIOR to the original MBA's problematic CPU. Why don't you include more educational information about the differences in the two CPUs rather than just clock speed? It really leads people down the wrong path to believe that the differences between the original MBA and revised MBA are 8% gains of the rev B MBA's Penryn CPU (only expressing speed differences between Merom and Penryn of same clock speed).
In my opinion, your points about the CPUs used in the both MBAs are EXTRMELY MISLEADING. So, while you are quoting "facts," I believe it would be far more educational for you to explain while the Penryn CPU is only 8% faster, it is a Low Voltage CPU. It uses LESS power than the Merom CPU used in the original MBA. By using less power, the Penryn CPU is far less likely to overheat the MBA. You could also explain that the Penryn CPU used in the revised MBA has 6 MB L2 Cache, while the original MBA's Merom CPU had only 4 MB L2 Cache (and explain what that means to the end user). Or you could point out the differences between the 65 NM process of the Merom CPU versus the 45 NM process of the Penryn CPU. Why just point out the 8% difference in computing power, and not further explain the ramifications of using the 65 NM Merom 20W CPU? Apple obviously learned its lesson with the original MBA, and it put a much nicer Penryn CPU in the rev B MBA. The much nicer Penryn CPU is a big part of the reason the revised MBA doesn't overheat! It extremely minimizes the chance of overheating, core shutdown, and complete lock ups... all well documented problems of the original MBA.
Your "fact telling" is part of the problem here with these types of posts. You provide a few "facts" but fail to tell the complete story of the Merom CPU used in the original MBA. Without telling people ALL of the differences between the original MBA and the revised MBA, people are likely to be led down a path that may be completely wrong for them.
The original MBA may be right for SOME people, but your information reporting is very misleading for most readers. Your facts make people believe that if they buy a rev B MBA, for double the price, their MBA will only be 8% faster than the original MBA. That is a serious disservice to Mac Rumors members. The revised MBA is NOT about an 8% gain in power. It is about components all being really well incorporated into a system that eliminates the problems experienced with the original MBA. A revised MBA buyer gets a much improved graphics system with a GPU (also eliminates heat). A revised MBA buyer also gets a SATA drive controller instead of a PATA drive controller (how about you quote the speed differences there)! The RAM in the new MBA is FASTER (why not quote the differences there too)! So, by spending more money, the revised MBA buyer doesn't just get an 8% faster CPU. You left out a lot of information that really matters and affects performance output a heck of a lot more than 8%! The rev B MBA buyers get a computer that performs really well; its an excellent computer that experiences very few of the common problems that plague the original MBA.
Proving someone wrong based on a technicality may make yourself feel smart, but it is not providing the audience with all of the necessary information to make a properly informed decision.
To make your point valid, you could have stated all of the differences and then pointed out some changes (like Cool Book helping some problematic original MBAs or how software rewrites has helped the underperforming original MBA). But there are a ton of differences between the two chips. And clock speed for clock speed comparisons really do not show the complete picture of differences between the original MBA and the revised MBA. This is a lot more than an 8% difference. The component makeup of the rev B MBA is completely different than its predecessor. To only include the difference between the two with same clock speeds is not helpful to the audience and tends to lead opinions down the wrong path.
I urge the audience to use ALL information and determine which MBA may be right for them. In this thread, I advised the OP to keep the unibody MB and add a 24 LED ACD in favor of trading it in for an original MBA and buying an iMac for heavy lifting. I believe the unibody MB is a solid Mac and paired with the 24 LED will do everything buying two separate computers will do. I was not attempting to sell the revised MBA to anyone. However, I dont believe the original MBA is right for most people. And I believe that sharing all information will lead potential buyers down the right path which is NOT always the cheapest path.
There goes 30 minutes I will never see again.
