ATI Radeon HD 4870 graphics card gets official

Just five days after ATI fessed up with an official release of its Radeon HD 4850, along comes a similar announcement for the just-leaked Radeon HD 4870. This dual-slot beast is finally being outed on the record, and at the very least, Diamond Multimedia's version will come stocked with 512MB of DDR5 memory, a clock speed of 725 MHz, 900MHz memory speed and 800 stream processors. The unit also provides CrossFireX upgradeability and should be available here soon from your favorite online retailer.
