Aside from the "all-day" battery life that comes alongside the upgrade to Intel's Haswell processors in the new MacBook Air, one of the other major improvements is the adoption of PCIe-based flash storage for much faster performance. The new PCIe flash will also be coming to Apple's radically redesigned Mac Pro later this year, and undoubtedly other Macs as well.
Available in capacities up to 512GB, this next-generation flash storage is up to 9x faster than a traditional 5400-rpm notebook hard drive. And it’s up to 45 percent faster than the flash storage in the previous-generation MacBook Air. So when you flip open MacBook Air, it’s ready to go right away. Even after a month in standby mode, the screen springs to life.
AnandTech has taken a closer look at flash storage performance and other benchmarks in the new MacBook Air, finding that read/write speeds are approaching 800 MB/s.
The drive in my system uses a Samsung controller, although I've heard that SanDisk will have a PCIe solution for Apple as well. A quick run through Quick Bench reveals peak sequential read/write performance of nearly 800MB/s.
This is a pretty big deal, as it is probably the first step towards PCIe storage in a mainstream consumer device that we've seen.
Beyond battery life and flash storage enhancements and the shift to Haswell, Apple's new MacBook Air brings several other enhancements as well, including faster 802.11ac Wi-Fi and dual microphones for reducing background noise.
I disagree with complaints out there that the MBA upgrades were optimized primarily for battery life, and not performance. As an example, the clock speeds were lowered to further extend battery life - keeping Geekbench performance roughly on par with last year's machines rather than providing the standard 20% improvement.
For one thing, this new Flash architecture isn't something to sneeze at.
But more importantly, I bet you anything the rMBP's are where they will look more to performance. Which only makes sense, as it would continue differentiating the two lines.
And if that's the case, going all-in for battery life is the right decision for their consumer-grade notebooks.
As an aside - 9to5mac anecdotally reports double the battery life on a 2008 MBP running Mavericks. Imagine combining those OS gains with the new Haswell machines!!!

Apple today released several open source large language models (LLMs) that are designed to run on-device rather than through cloud servers. Called OpenELM (Open-source Efficient Language Models), the LLMs are available on the Hugging Face Hub, a community for sharing AI code. As outlined in a white paper [PDF], there are eight total OpenELM models, four of which were pre-trained using the...
Apple has dropped the number of Vision Pro units that it plans to ship in 2024, going from an expected 700 to 800k units to just 400k to 450k units, according to Apple analyst Ming-Chi Kuo. Orders have been scaled back before the Vision Pro has launched in markets outside of the United States, which Kuo says is a sign that demand in the U.S. has "fallen sharply beyond expectations." As a...

Woosh.
That's the sound of a joke going right over your head.
lol "Alright". some people can not be pleased.
