This card also fills the overall price/performance hole in AMD’s 5000 series lineup, giving them something between the $9 9 5670 and the $50-$60 5450. This allows AMD to fill a potential hole in their lineup by offering a low-profile GPU with better than bargain-bin performance. Here AMD is not leaving that up to their vendors, and is doing an official retail low-profile design for their more powerful Redwood GPU. For the 4000 series AMD’s only official low-profile card was the 4350, although vendors were known to do low-profile versions of the 4550 (RV710) and the 4650 (RV730). None of the SIMDs have been disabled however, so this is a fully functional Redwood GPU.įinally, in another significant departure from the 4000 series, this is AMD’s second official low-profile video card. 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. 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 first of which is to significantly castrate the 5670’s memory bandwidth. Instead it’s a slower Redwood card, putting it in the ballpark of the 5670’s rather than the 5450’s.ĪMD has done 3 things to differentiate the 5570 from the 5670. 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. Right off the bat, the 5570 marks a bit of a departure from AMD’s numbering scheme for the 4000 series. Today we’re looking at that 5500 series card, the Radeon HD 5570. Last week we saw the launch of the 5450, utilizing the Cedar GPU and finishing off AMD’s chip stack. When AMD launched the 5670, they told us they had 2 more cards on the way: the 5450, and a 5500 series card.
