[ Power Consumption & Temperatures ]

The Radeon HD 7770 proved to be very power efficient, using slightly less power than the old HD 6750 and considerably less than the HD 6770, which is impressive given on average it was 26% faster. The Radeon HD 7750 used slightly less power again, and despite using 27% less power than the GeForce GTX 550 Ti it was on average just 2% slower. The HIS Radeon HD 7750 with its upgraded cooler maxed out at 64 degrees when stress testing with FurMark, this is the same temperature reached by the Gigabyte GeForce GTX 460. The majority of low-end to mid-range graphics cards operated at around 60 degrees, so nothing out of the ordinary here. On the other hand the AMD Radeon HD 7770, which is based on the reference design, did get quite hot reaching 81 degrees. We should point out that at this temperature the graphics card fan never spun up to speeds that made it more noticeable over the case fans. Furthermore the Radeon HD 7770 is one of the few graphics cards using a reference cooler in the above graph.

Posted on: 02/15/2012 09:03 PM AMD you are ripping us off, nVidia give us some competition please. Such a small chip can't be expensive to produce an certainly not worth what the consumer is charged for. 4770 -> 5770 -> 6770 -> 7770...... Looking for a GPU for my Mini-ITX HTPC but probably stick with a 6850 (I have the space and PSU). For this price I expect something that can play Full HD (Games ) with more frames then this offers. Too bad because I do like the power envelope of this thing. (Steve, thanks for the review)

ProX	Posted on: 02/15/2012 09:43 PM I agree massive rip off. How can AMD release a product that is so much slower than the competition and charge pretty much the same price. As the review said the GTX 560 is like 9 months old now and still much faster. Shame on you AMD!
