As you may have noticed by now, AMD just introduced the Radeon HD 7790, a new $149 card that fills the empty space between the Radeon HD 7770 and the Radeon HD 7850. According to AMD, the card offers almost 50 percent more processing power than the Radeon HD 7770, while having a TDP of just 85W, only 5W more than the 7770.
The card has 896 stream processors, 56 TMUs, 16 ROPs, a 128-bit memory bus, 1GB GDDR5 memory clocked at 6000MHz and a 1GHz core clockspeed. It also introduces dynamic clock adjustment technology for reducing power consumption.
A quick look at The Tech Report's review shows the Radeon HD 7790 more than holds its own overall. In real-world performance the card is quicker than the GeForce GTX 650 Ti, while also outdoing the Radeon HD 7850 1GB in many tests.
Add to that the Radeon HD 7790's power efficiency, its low noise levels, and the free copy of BioShock Infinite in the box, and it looks like we have a winning recipe from AMD.
