Macbook


  
Although it shares its name with the earlier MacBook models from yesteryear, the MacBook "Core M" 1.1 12-Inch (Early 2015) and its slightly higher-end brother -- the MacBook "Core M" 1.2 12-Inch (Early 2015) -- are radically different than their predecessors.

"Reinvented" for the ultimate in portability, the "Early 2015" MacBook models are even lighter and thinner than the smallest models from the MacBook Air series, and with just one USB-C port for connectivity and a headphone jack, the hardware more resembles an iPad with an attached keyboard than it resembles earlier Apple notebooks. However, like the MacBook Air, these MacBook models run OS X rather than the iPad's iOS.
The MacBook "Core M" 1.1 12-Inch (Early 2015) features a 14-nm 1.1 GHz Intel "Core M" processor (M-5Y31) with two independent processor "cores" on a single chip, a 4 MB level 3 cache, an "integrated" Intel HD Graphics 5300 graphics processor that shares system memory, 8 GB of onboard1600 MHz LPDDR3 SDRAM (that cannot be upgraded), and 256 GB of onboard PCIe-based flash storage (that also cannot be upgraded).

This all is housed in a wafer thin (0.14-0.52 inch), 2.03 pound, aluminum case offered in "traditional" silver color as well as gold (pictured) and a darker slate "Space Gray" color option. It also packs a lowly 480pFaceTime webcam, a backlit full-size keyboard with a thin "butterfly mechanism" keyboard design, a clever haptic-capable "Force Touch" trackpad, and a beautiful 12" TFT LED-backlit active-matrix "Retina" display (2304x1440 native resolution at 226 ppi). Apple boasts that the notebook additionally uses a new "tiered" battery design to maximize space inside the chassis and delivers 9-10 hours of runtime depending on use.

The MacBook Pro "Core i7" 2.5 15-Inch (Dual Graphics/Force Touch - Mid-2015 Retina Display) features a 22 nm "Haswell/Crystalwell" 2.5 GHz Intel "Core i7" processor (4870HQ), with four independent processor "cores" on a single silicon chip, a 6 MB shared level 3 cache, 16 GB of onboard 1600 MHz DDR3L SDRAM (which cannot be upgraded later), 512 GB of PCIe-based flash storage, and dual graphics processors -- an AMD Radeon R9 M370X with 2 GB of dedicated GDDR5 memory and an integrated Intel Iris 5200 Pro graphics processor with 128 MB of "Crystalwell" embedded DRAM (and shared system memory). It also has an integrated 720p FaceTime HD webcam and a high-resolution LED-backlit 15.4" widescreen 2880x1800 (220 ppi) "Retina" display in a case that weighs just less than 4.5 pounds (2.04 kg). It does not have an internal optical drive.
Connectivity 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.

In addition, this model has a backlit keyboard, a new advanced "Force Touch" trackpad, a "MagSafe 2" power adapter, and an internal, sealed battery that provides an Apple estimated 9 hours of battery life.

Compared to its predecessor, this model is similar, but it has a faster graphics processor, faster flash storage, a higher capacity battery, and a more advanced "Force Touch" trackpad. It has some different identifiers, too.

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 onboard1866 MHz LPDDR3 SDRAM (which can 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, and an integrated Intel Iris Graphics 6100 graphics processor that shares memory with the system. It also has an integrated 720p FaceTime HD webcam, and a high-resolution LED-backlit 13.3" widescreen 2560x1600 (227 ppi) "Retina" display in a case that weighs just less than 3.5 pounds (1.58 kg). It does not have an internal optical drive.
Connectivity 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.

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.

Compared 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.

The Apple MacBook Air "Core i5" 1.6 13-Inch (Early 2015/Broadwell) features a 14-nm "Broadwell ULT" 1.6 GHz Intel "Core i5" processor (5250U) with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 4 GB of onboard 1600 MHz LPDDR3 SDRAM (which can be upgraded to 8 GB at the time of purchase, but cannot be upgraded later), 128 GB or 256 GB of 4 Lane PCIe-based flash storage, and an "integrated" Intel HD Graphics 6000 graphics processor that shares system memory.
This all is packed in a razor thin 0.11-0.68 inch), 2.96 pound, aluminum case with an integrated 720p "FaceTime HD" webcam, a backlit full-size keyboard and a 13.3" widescreen TFT LED backlit active-matrix "glossy" display (1440x900 native resolution).

Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, analog audio out, a single "Thunderbolt" 2 port, two USB 3.0 ports, and an SDXC-capable SD card slot.

Compared to its predecessor, this model looks effectively identical, but has a more advanced processor and architecture, more advanced graphics, "twice as fast" 4x PCIe storage and Thunderbolt 2 support. It has some different identifiers, too.

The Apple MacBook Air "Core i5" 1.4 11-Inch (Early 2014/Haswell) features a 22-nm "Haswell" 1.4 GHz Intel "Core i5" processor (4260U) with two independent processor "cores" on a single chip, a 3 MB shared level 3 cache, 4 GB of onboard 1600 MHz LPDDR3 SDRAM (which could be upgraded to 8 GB at the time of purchase, but cannot be upgraded later), 128 GB or 256 GB of PCIe-based flash storage, and an "integrated" Intel HD Graphics 5000 graphics processor that shares system memory.
This all is packed in a razor thin (0.11-0.68 inch), 2.3 pound, aluminum case with an integrated 720p "FaceTime HD" webcam, a backlit full-size keyboard and an 11.6" widescreen TFT LED backlit active-matrix "glossy" display (1366x768 native resolution).

Connectivity includes 802.11ac Wi-Fi, Bluetooth 4.0, analog audio out, a "Thunderbolt" port, and two USB 3.0 ports.

Compared to its predecessor, this model is practically identical -- with the same design and architecture -- but it has a faster processor, longer reported battery life (due to OS X improvements rather than hardware), and a few, but not many, different identifiers, as well.
