Imac 27 Inch in Benoni, Gauteng for sale

Soort:
Apple
The iMac "Core i5" 2.8 27-Inch Aluminum (Mid-2010) is powered by a Quad Core 2.8 GHz Intel "Core i5" I5-760 (Lynnfield) processor with a dedicated 256k level 2 cache for each core and an 8 MB shared level 3 cache. In lieu of a system bus, it has a "Direct Media Interface" (DMI) that "connects between the processor and chipset" at 2.5 GT/s.
By default, it is configured with 4 GB of RAM (1333 MHz PC3-10600 DDR3 SDRAM), a 1 TB (7200 RPM) hard drive, a vertically-mounted slot-loading DVD±R DL "SuperDrive", and ATI Radeon HD 5750 graphics with 1 GB of dedicated GDDR5 memory.
It also has a built-in iSight video camera and built-in stereo speakers underneath the 27" glossy 16:9 LED-backlit TFT Active Matrix LCD (2560x1440 native) display "with IPS technology".
Connectivity includes four USB 2.0 ports, a Firewire "800" port, built-in AirPort Extreme, and Gigabit Ethernet, as well as an audio capable Mini DisplayPort, which supports an external display up to 30" (2560x1600).
Externally, the "Mid-2010" iMac line uses the same "edge-to-edge" glass design and "seamless all aluminum enclosure" as the "Late 2009" models replaced. Internally, however, the "Mid-2010" line is equipped with faster processors, faster graphics processors, and faster memory, as well as support for the SDXC SD card format.
The "Mid-2010" iMac models include a compact aluminum Apple Wireless Keyboard and a multi-touch "Magic Mouse," but for US$69 could be upgraded to include a multi-touch "Magic Trackpad" that "enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe three fingers to flip through a collection of web pages or photos" just like on Apple notebooks from the same era.

2.8 GHz
Processor Type:
Core i5 (I5-760)
Details:
This model is powered by a 64-bit Intel Core i5 "Lynnfield" processor with quad cores (four independent processor cores on a single silicon chip). Each core has one thread, for a total of four threads for the system, as well as a dedicated 256k level 2 cache. The processor cores share an 8 MB level 3 cache. It also supports "Turbo Boost" -- which "automatically boosts the processor speed based on workload" (so if an application is only using one of the four cores it will automatically increase the speed of the core in use and turn off the unused cores) -- up to 3.33 GHz when needed. However, it does not support Hyper Threading.




Custom Speeds:
2.93 GHz (Core i7)
Architecture:
64-Bit
Details:
