iMac with underclocked ATI Radeon 4670
November 8th, 2009
It’s sad Apple lied, as usually, on the Graphic Card implemented in new iMac…
Not only Radeon 4670 are underclocked on iMac (680Mhz core instead 750Mhz, -10%), the memory is underclocked too (790Mhz instead 800Mhz), but they put only 256MB video ram instead usual 512MB or even 1GB that you could find on any retalier for the same GPU!
2X or 4X more memory on usual Radeon 4670 makes a real difference when you have a 2560×1440 display to drive!!!
Addenda: Actual Mac Pro have ATI Radeon 4870 option. But with only 512MB video ram instead 1GB or 2GB that you will find in retail! 512MB is good for entry-level cards, not for high-end!
