Unlike pre-2007 models, where every USB port could provide 500 mA of power, only a single high-powered device can be attached to the USB ports, and software will enable one of its downstream ports to supply 500 mA of power. At this time we do not know if it applies to the new model. This is the oldest MacBook Pro to officially support macOS Sierra.Įditor’s note: The next paragraph is from the profile of the previous version of the MacBook Pro. This is the only current Mac notebook with ExpressCard/34.Īpple uses a true 24-bit display on all 17″ Unibody MBP models. Only the new 13″ MacBook Pro beats it.Īs before, 4 GB of RAM is standard, and it officially supports up to 8 GB of RAM. The new 17″ MacBook Pro retails at $200 less than the previous model, and you can get an antiglare display for an additional $50.Īpple has also improved overall field time – the 95 Watt-hour battery is rated at 8-9 hours of wireless productivity, a big improvement from 8 hours in the 2009 model. The Intel GPU uses 256 MB of system memory, while the Nvidia GPU has 512 MB of dedicated video memory. The other big change comes in the graphics department: These are the first Macs to use Intel HD Graphics – and the first to use Nvidia’s automatic switching GeForce GT 330M GPU. You can’t compare the new i5 and i7 models with previous ones by looking at clock speed, as they are not single clock speed chips. For instance, a 2.53 GHz i5 may outperform a 3.06 GHz Core 2 Duo.

These CPUs brings something new to Apple’s portable line, hyperthreading, which lets the dual-core CPU appear to the operating system as four cores.Ī further advantage of Intel’s “i” family of CPUs is that they can overclock themselves by 25% or more depending on the number of cores and processes in use.

However, because they use the mobile Intel i5 and i7 CPUs instead of the older, less efficient Core 2 Duo chips, they are more powerful despite lower clock speeds.

The 15″ and 17″ Mid 2010 MacBook Pro models have lower clock speeds than the models they replace.
