second thunderbolt port (now you can have 2 displays native and not be down a precious USB3) move the thunderbolt port beside the power connector (no more stethoscope when plugged in driving a display) Here are some "cheap" things they could have done to actually make this product an upgrade:

MICHAEL VEY BOOK 4 QUIZ PC
You've been criticizing PC makers for 2 years about the 1366x768 resolution, and here we have apple in 2013 and you say they "perhaps should have changed" "The only thing that hasn't changed, that perhaps should have is the display. Apple has been deliberately stifling user upgrades for years….That is why they have proprietary connectors…ON EVERYTHING.your readers, and your reviewer knows this. I think anand, like many other review sites invested heavily in apple stock and are now trying to stop the bleeding. "the m.2 spec wasnt far enough along to be used in this generation" Whoop dee f*ckin do…….This is apple innovation? Ultimately, You get a slower, longer lasting air for a 100 bucks less that carries over all the little annoyances from last year." "intel came out with a new CPU, samsung made a new SSD and apple slapped it together last minute in an existing design.
MICHAEL VEY BOOK 4 QUIZ UPGRADE
The upgrade costs $150 regardless of base model. I don't suspect this will matter much for most MBA users, but anyone looking to play around with Haswell's TSX instructions will want to opt for the higher end SKU. What's arguably coolest about the i7-4650U is it enables Haswell's Transactional Synchronization Extensions (TSX-NI), a feature which is unfortunately disabled on the i5-4250U. Intel likely maintains the same TDP by binning for power the i7-4650U is probably capable of running at higher frequencies without any appreciable increase in voltage. All in all, this should be a very healthy upgrade in performance. The 4650U retains the same 15W TDP as the i5-4250U, but it increases its base clock speed to 1.7GHz and max turbo to 3.3GHz.

Haswell does feature a not insignificant gain in IPC compared to Ivy Bridge, which should help offset the power constraints that could otherwise force a larger regression in performance.īoth 2013 MBAs ship with the same CPU by default, and both can be upgraded to the same higher end SKU: a Core i7-4650U.

Max turbo clocks are identical between the Haswell ULT CPUs Apple picked this round and the Ivy Bridge models before, but with a lower TDP it’ll be harder to always sustain the same frequencies given the right workload. In Ivy Bridge the PCH was off package and wasn’t included in the 17W TDP. The thermal limit is even more dramatic since with Haswell ULT, the 15W includes the CPU/GPU as well as the on-package PCH. The lower base clock alone shouldn’t mean much, but the max TDP of the CPUs in the new MacBook Air falls as well - from 17W down to 15W. When faced with a power/performance tradeoff, it’s clear on which side of the fence Apple will fall whenever the MacBook Air is concerned.
MICHAEL VEY BOOK 4 QUIZ PRO
The Air is about portability, while the Pro is about performance. The line between MacBook Air and MacBook Pro has to be well defined. To understand Apple’s CPU choice, you have to understand that Apple is primarily concerned about improving battery life this generation. Apple keeps things simple across the 2013 MacBook Air lineup by configuring both 11 and 13-inch models with the same base CPU: a Core i5-4250U.
