Sapphire RX 470 Platinum, Same Price As RX 480 But Weaker Performance
GamersNexus recently dissected Sapphire RX 470 Platinum edition and the result doesn’t seem very encouraging. When the RX 470 launched recently, it received generally favorable reviews thanks to its low price tag and entry level gaming target. That however seems to be changing now that custom variants of the GPU are surfacing.
One such custom made GPU is the Sapphire RX 470 Platinum, priced at $200 which is the same as reference RX 480 4GB. The RX 470 might be a good GPU in its regard but its bestselling point is its price tag, as long as it remains under $180 because upon reaching $200 or even beyond in the case of XFX with its $220 Black Edition, there is no point in getting this GPU when the RX 480 delivers better performance.
In their breakdown of the Sapphire RX 470 Platinum, GamerNexus discovered some disturbing things about the card.
The 470 seems to be using the same PCB as the RX 480 although the VRM (voltage regulator module) has been reduced to a four-phase power design to save cost. The card also has eight VRAM modules made by SK Hynix.
Unlike the 480, the RX 470 cannot be “unlocked” to 8GB memory. The VRAM modules used in it are combined in such a way that two modules make up 1GB GDDR5 memory at 1750MHz. By comparison, the RX 480 has modules at 2000MHz. The cooler in RX 470 is also a lot similar to 480 although without the copper coldplate.
So essentially, for the same price as a reference AMD RX 480 4GB, Sapphire RX 470 delivers identical cooling, slower VRAM and a weaker VRM.
The factory overclock that the GPU comes with is a mere 10MHz which provides no benefit at all at 1216MHz, especially when considering the result of Thermal Endurance tests which show the clock doesn’t remain stable at above 1200MHz.
