But for single threaded stuff, the GHz weren’t measuring up. It destroys at multithreaded tasks like video encoding, with 16 v-cores. But at six years old, it’s starting to feel its age. I upgraded the video card, upgraded to dual SSDs in RAID-0, upgraded to a PCI-e internally-RAID-0 SSD card, added a Blu-ray drive, bought a 30-inch screen in addition to the 24 I had. But way before that, in 2009, I got a Mac Pro tower. In 2012, I got a 13 inch MacBook Air (3 pounds). In 2010, in an effort to atone for my sins against gravity, I “downgraded” to a 13 inch “unibody” MacBook Pro (only 4.5 pounds!). In 2007 I upgraded to the ridiculously large 17 inch MacBook Pro. I started in 2005 with a 15 inch PowerBook G4. Nothing more.My history with portable Macs has been all over the place. In addition, this model has a backlit keyboard, a clever haptic-capable “Force Touch” trackpad and an internal, sealed battery that provides an Apple estimated 10 to 12 hours of battery life depending on use.Ĭompared to its predecessor, this model looks nearly identical externally, but it has a more advanced processor and architecture, more advanced graphics processor, faster RAM, a faster SSD, and a higher capacity battery as well as the aforementioned more advanced “Force Touch” trackpad.ġ3.3″ widescreen high-resolution LED-backlit 2560×1600 (227 ppi) “Retina” display It does not have an internal optical drive.Ĭonnectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, two USB 3.0 ports, two “Thunderbolt 2” ports, an HDMI port, an audio in/out port, and an SDXC card slot. It also has an integrated 720p FaceTime HD webcam, and a high-resolution LED-backlit 13.3″ widescreen 2560×1600 (227 ppi) “Retina” display in a case that weighs just less than 3.5 pounds (1.58 kg). The MacBook Pro “Core i5” 2.7 13-Inch (Early 2015 Retina Display) features a 14 nm “Broadwell” 2.7 GHz Intel “Core i5” processor (5257U), with dual independent processor “cores” on a single silicon chip, a 3 MB shared level 3 cache, 8 GB of onboard 1866 MHz LPDDR3 SDRAM (which could be upgraded to 16 GB at the time of purchase, but cannot be upgraded later), 128 GB or 256 GB of 4 Lane PCIe-based flash storage by default (only 128 GB by default starting on October 27, 2016), and an integrated Intel Iris Graphics 6100 graphics processor that shares memory with the system.
