Description

Apple iMac “Core 2 Duo” 2.4 20-Inch Aluminum (Early 2008/Penryn) is powered by a 2.4 GHz Intel “Core 2 Duo” processor (E8135), with two independent processor “cores” on a single silicon chip, a 6 MB shared level 2 cache, a 1066 MHz system bus, 4 GB of RAM (800 MHz DDR2 SDRAM, PC2-6400), a 250 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading DVDR DL “SuperDrive”, ATI Radeon HD 2400 XT graphics  a built-in iSight video camera, and built-in stereo speakers underneath the 20″ glossy TFT Active Matrix LCD (1680×1050 native) display.

Physical Features

Externally, the iMac “Core 2 Duo” Aluminum (Early 2008/Penryn) models essentially are the same as the original Aluminum models that these replaced, with the same housing and glass cover that “joins precisely to the aluminum enclosure creating a virtually seamless front surface”. The Early 2008/Penryn models, likewise, are paired with the same “ultra-thin alumium” Apple Keyboard (0.33 inches at the front edge).

Super Fast Connectivity

Connectivity includes three USB 2.0 ports, a Firewire “400” port and a Firewire “800” port, built-in AirPort Extreme, and Gigabit Ethernet, as well as mini-DVI, which supports an external display in “extended desktop” mode.

Energy Efficient
Internally, however, the “Early 2008/Penryn” revision of the “Aluminum Core 2 Duo” models have faster and more energy-efficient 45 nm “Penryn” processors compared to 65 nm “Merom” processors in the original “Aluminum” models — larger level 2 caches (6 MB compared to 4 MB), faster frontside buses (1066 MHz compared to 800 MHz), and faster memory (PC2-6400 compared to PC2-5300). Some configurations shipped with more default memory as well.

The ATI Radeon HD 2400 XT graphics

The Radeon HD 2400 XT is a graphics card by ATI, launched in June 2007. Built on the 65 nm process, and based on the RV610 graphics processor, in its RV610 PRO variant, the card supports DirectX 10.0. The RV610 graphics processor is a relatively small chip with a die area of only 85 mm² and 180 million transistors. It features 40 shading units, 4 texture mapping units and 4 ROPs. ATI has placed 256 MB GDDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 650 MHz, memory is running at 500 MHz. Being a single-slot card, the ATI Radeon HD 2400 XT does not require any additional power connector, its power draw is rated at 25 W maximum. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. Radeon HD 2400 XT is connected to the rest of the system using a PCIe 1.0 x16 interface
