Okay, technically the previous (the Radeon HD 4890) was “factory overclocked” and also the new card is “reference clocked,” which means there’s most likely more headroom for overclockers within the 7770. AMD states the low-carrying out, 75-watt HD 7750, is notable since it doesn’t need a separate energy connector.
AMD paper-released its much greater-finish (greater performance by design, but lower-clocked) 7900 series in December 2011, but cards for the reason that selection typically choose over $500. The 7770, by comparison, applies to $159, as the 7750 applies to $109. So you’re getting 7000-series performance on the shoestring budget, right?
The issue for AMD today isn’t the energy/performance curve, it’s the cost/performance curve. 16 several weeks ago AMD released the Radeon HD 6850 at $179 amongst fierce competition from NVIDIA. Disregarding the present cost from the 6850 for now, normally the 7770 provides 90% from the 6850’s gaming performance for 90% from the 6850’s launch cost. Quite simply in 16 several weeks AMD has moved nowhere across the cost/performance curve - should you pass launch prices you’re obtaining the equivalent performance per dollar today while you did in October of 2010.
According to current prices, the HD 7770 reaches best 15% less expensive than the GTX 560, though some cards can sell for less than $170, making the HD 7770 only 6% cheaper. Thinking about individuals figures, we can’t observe how anybody could justify buying the HD 7770. Its only redeeming feature is it consumes nearly 30% less energy under load, but many players would rather the additional performance to energy savings.
