After using NVIDIA's G84 chips in its MacBook Pro, Apple announced a new version of its iMac today, which will be powered by AMD Radeon HD 2400 and 2600 GPUs.
The new iMac sports a 20" or 24" glossy widescreen display at 1680x1050 or 1920x1200, respectively. The 2.0GHz 20" iMac uses a AMD Radeon HD 2400 XT with 128MiB of GDDR3, while the faster 2.4GHz 20" and 24" models contain the Radeon HD 2600 PRO with 256MiB of GDDR3.
One thing of note is that these are not the traditional desktop RV610 and RV630. Instead, the new iMac is built upon Intel's Santa Rosa platform and as a result, all chips used are their mobile variants. The Core 2 Duo is one of the mobile T-series chips, and the Radeon 2400 is M72 while the 2600 is M76.
The new iMac is available now, with prices ranging from $1199 for the 2.0 Ghz 20" model to $2299 for the 2.8GHz Core 2 Extreme-powered 24" model.
