Although the $1,999 15-inch model ships with Intel’s Iris Pro integrated graphics, users can always opt the $2,599 model, which includes a Nvidia GeForce GT 750M GPU which should provide you with more graphics processing power over Iris Pro.Ģ.5GHz dual-core Intel Core i5 processor (Turbo Boost up to 3.1GHz) with 3MB shared 元 cacheĢ.4GHz dual-core Intel Core i5 processor (Turbo Boost up to 2. This could extend battery life an additional two hours beyond the previous models, offering a total of up to nine hours of usage and 30 hours of standby time. 2012 Survey of AARP Members in Indiana on Election Issues. Apple claims that battery life has gotten a significant boost thanks to updated specs and software optimization courtesy of Mavericks. Crucial MX500 SATA 2TB Intel Optane SSD 905P 480GB Pros Up to 2.6GBps read speeds Durable. The 13-inch model 15-inch models are slightly thinner and lighter than their predecessors, measuring 0.71 inches thick and weighing in at 3.46 and 4.46 pounds, respectively.

Both the 13-inch and 15-inch MacBook Pros feature the newly-launched Mavericks OS, in addition to 802.11ac Wi-Fi and Thunderbolt 2.0, and integrated graphics courtesy of Intel Iris and Iris Pro.Ĭosmetically, the new models aren’t vastly different. There are a lot of USB 3.0 drives on the market, and they are far more affordable than Thunderbolt drives. The USB 3.0 specification is over 10x as fast as USB 2.0 and has half the bandwidth of Thunderbolt.

The SATA cable is the weak link, one of many reasons Apple went to the PCI-e and soldered-in storage. They can be damaged quite easily if the unit is mishandled during assembly or re-assembly. This type of cable can experience cracks in traces due to aging, heat, vibration, impact and abrasion. Those SATA cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires. As it cools down, electrical contact may once again be restored. As a unit heats up, it expands, and as it expands, the crack widens, eventually forcing a complete electrical separation to exist on both sides of the crack, hence a failure.

In the case of an intermittent generic failure, the electrical continuity of a cracked trace on both sides of the crack is very often a function of the temperature of the unit at the point where the crack exists. It is however no mystery why old cables fail when switching from HDD to SSD. Agreed, a new SATA cable is a nominal expense and highly recommended.
