AMD HD7770 Review
The target for the HD7770 is, as always, the sub $200 (about £150 usually) market. This is one of the tightest contested sectors in the whole graphics card world, with a tenner here and there moving you a few models up or down, gaining lots of extra performance if you can step up to the next one. As we're still waiting for the HD78x0 cards there will be quite a gap between the performance of the HD7770 when compared to the next model up in the Radeon range.
One of the many benefits that Steam brings is the ability to see what is genuinely the most popular card around, and unsurprisingly the HD5770 is still up there. Although this does beg the question "What happened with the 6 series", as none of the cards AMD have chosen to highlight are from their much-maligned previous iteration.
The clockspeeds that we can attain from the ever-shrinking dies are becoming mind-blowing, and nowhere is this truer than with the HD7770 which comes out of the box at a whopping 1GHz core. Even more surprising is how low the power consumption is. A mere 3W when your monitor has gone into power-saving mode, and only 80W when rocking hard.
