notice that Gigabyte’s GV-N470UD-13I GTX 470 runs at stock reference speeds but achieves almost identical benchmark scores to last month’s kick-ass overclocked EVGA GTX 470. Blame it on new drivers versus old.To be fair, the N470UD-13I isn’t exactly a stock card. While the card ships at reference clock speeds for core, shader, and memory, Gigabyte builds the board using its Ultra Durable manufacturing methods, which includes two-ounces-of-copper PCB technology, Japanese solid capacitors, high-end Samsung or Hynix GDDR5 memory, and low RDS(on) MOSFETs, which are designed to minimize switching resistance for faster capacitor charging and discharging. The PCB itself is blue, unlike many reference GTX 470 cards.
