Review: Apple with Core i3, i5 and i7 for iMac
See how Apple iMacs with “Nehalem” Core i3, i5 Dual and Quad Core CPUs and Core i7 Quad Core can do.
The most recent iMacs advanced Apple’s consumers by launching its “Nehalem” Core i3, i5 Dual and Quad Core CPUs and Core i7 Quad Core options. Throwing away Core 2 Duos which were used on the previous of iMacs they developed.
The newest processors for the system has a 3GHz territory, which has a range of 3.06 or 3.2GHz Core i3 or 3.6GHz Core i5 options on the 21.5 inch model (each with 4MB of L3 cache), or a 3.2GHz Core i3 or 2.6GHz Core i5 (both with 4MB of L3 cache) or a Quad Core 2.8GHz i5 or Quad Core 2.93GHz Core i7 (both with 8MB of L3 cache) on the 27 inch model.
The previous Cores, i5 and i7 iMacs were only equipped with 2.8GHz or even below. But its still out spaced the 3.33GHz Core 2 Duo. This gives credit to the Quick Path memory architecture of Nehalem. It includes a direct memory controller on the CPU rather than RAM’s external chipset.
The Nehalem microarchitecture puts and end to the former Apple partner, NVIDIA and its integrated 9400M across the board which provide Macs with standard chipset functions (e.g.: providing a memory controller, SATA, USB, PCIe, audio, and networking functions) and graphic features.
The new iMac models will offer ATI Radeon HD dedicated graphics processors:
The low end 21.5 inch iMac uses an ATI Radeon HD 4670 with 256MB of GDDR3 memory.
The higher end 21.5 inch iMac uses ATI Radeon HD 5670 with 512MB of GDDR3 memory.
The dual core 27 inch iMac uses an ATI Radeon HD 5670 with 512MB of GDDR3 memory.
The quad core 27 inch iMac uses an ATI Radeon HD 5750 with 1GB of GDDR5 memory.
Windows PC’s are often packed with more graphics RAM. Just like Acer’s similarly equipped Gateway One, that supplies the same ATI Radeon HD 4670 and a 1GB dedicated graphics for RAM. Its prime benefactors are video games because it allows the game to load texture maps and other graphic data RAM for best performance. iMacs are designed not to feed on graphics RAM but more or less be a digital media hub running iLife and other creative apps. This gives us the idea that Macs are not for video gaming. But more or less, the gamers still opt for Windows instead of Mac. Well, the iMac’s new options for 512MB to 1GB of Graphics RAM will help users who plan to have Windows games to run on Mac with the help of Boot Camp.
“Base models of the iMac ship with 1TB 7200 RPM SATA hard drives and offer an identical 2TB upgrade option (apart from the entry level 21.5 inch model, which ships with a 500GB hard drive). All models also ship with 4GB of RAM, expandable to an officially supported 16GB (8GB on the 21.5 inch models). Prices are unchanged from the previous models, and range from $1199 or $1499 for the 21.5 inch iMac to $1699 or $1999 for the 27 inch model.”
“CPU upgrades cost a $200 premium, the video card bump costs $150, while the 2TB disk upgrade has dropped from a pricy $250 option to a more reasonable $150. Both models provide four RAM slots, giving users the option to upgrade incrementally without having to throw away RAM to make room for new parts”
