The 5670 is noticeably faster than the GT 220. However the ATI 5670 is at best an entry level card. It's not a gaming card by any stretch.|||When AMD launched the 5670, they told us they had 2 more cards on the way: the 5450, and a 5500 series card. Last week we saw the launch of the 5450, utilizing the Cedar GPU and finishing off AMD’s chip stack. Today we’re looking at that 5500 series card, the Radeon HD 5570.
Right off the bat, the 5570 marks a bit of a departure from AMD’s numbering scheme for the 4000 series. While the Radeon HD 4550 was the faster of the two cards utilizing AMD’s cheapest GPU (RV710), the 5570 is not a faster Cedar card. Instead it’s a slower Redwood card, putting it in the ballpark of the 5670’s rather than the 5450’s.
AMD has done 3 things to differentiate the 5570 from the 5670. The first of which is to significantly castrate the 5670’s memory bandwidth. While the 5670 had 1GHz (4GHz effective) GDD5, the 5570 drops that for simple 900MHz (1.8GHz effective) DDR3, giving the card only 45% of the memory bandwidth of the 5670. The second change is more customary, and that is lowering the core clock from 775MHz to 650MHz, leaving the card with roughly 83% of the computational/rendering/texturing performance of the 5670. None of the SIMDs have been disabled however, so this is a fully functional Redwood GPU.
Finally ATI 5670 is better than GT220|||What GPU is the best depends on your whole rig. But for itself the ATI wins here.|||ATI 5670... one of the most powerful gc.
