CES: 1GHz HD 5870 from Gigabyte Posted on 13/01/2010 at 03:03 by Damien
Gigabyte were showing a series of customized Radeon HD 5800s at CES, all based on an identical PCB (some components may differ however). While the cooling system is similar, it isn’t completely identical on the Radeon HD 5850 Overclock as on the two Radeon HD 5870s: the Ultra Durable and Super Overclock have an extra heatpipe. We don’t yet know the clocks for the first two of these but the Radeon HD 5870 Super Overclock will be clocked at 1000 MHz (GPU) and 1300 MHz (GDDR5). In comparison with the stock model clocked at 850/1200 MHz, this corresponds to a 17% increase. The 8% increase in bandwidth is more modest.
Given that the Radeon HD 5870 is more limited by memory bandwidth than processing power in current games, it’s a shame that the bandwidth hasn’t gone up more. Lastly, note that Gigabyte has told us not to expect 2GB Radeon HD 5800 models in the immediate future.
