AMD Radeon HD 6790, a new video card for full HD 1080p gaming

Available for $150, the Radeon HD 6790 is AMD’s answer to NVIDIA’s GTX460 and here are some of its specifications; 1024MB GDDR5 memory frequency, 840MHz GPU and 800 stream processors.

What AMD is trying to achieve is a more powerful device than the HD 5770 card but not so much as the HD 6850.

Predictably, its performance offers no threat to AMD’s single-GPU flagship, but the 6790′s 840MHz graphics and shader clock speeds plus 1GB of GDDR5 running at an effective 4.2GHz data rate don’t seem like anything to sniff at either.

Coming soon: AMD Radeon HD 6990

AMD Radeon HD 6990 gets closer to an official release date. The video card based on two series graphics core Cayman, the same used by Radeon HD 6970, has faced similar problems related to maintaining acceptable levels of energy consumption, but the AMD relative is believed to have the advantage of using a less expensive graphics processors.

The specifications for the Radeon HD 6990 promises a total of 3072 stream processors and no more than 4GB memory of gDDR5 (2GB for each GPU). Nevertheless still unconfirmed rumors claim the presence of no less than 3840 stream processors, a detail that would make a serious competitor for the GeForce GTX 595.
